As a small child, I heard from an adult that houses were built to last 100 years. From this, I concluded that the second the house reached 100 years, it would immediately collapse, with the inhabitants inside.
I work in the car industry and some customer told me, "they can build older semitrucks to last a million miles but you think that exist now?" Later everyone went the vw route and started making their parts out of plastic... Plastic intake manifolds, plastic valve covers, etc. And having the 2.0 liter turbo engine has the holy grace of power and fuel consumption. VW had veen doing that since 2005 Harley Davidson has also been doing the european treatment for years making their bikes harder to work on If its popular, theirs some millionaire douche wanting to make the most profit iff it Why do you think most car dealerships charges over 150$ an hour for Labor, that car is made for you to come back in and spend more 💰 😉
I have been using 18650 battery's for 6 years now, still working great, all of them have no problems, They have been heavily used..... And i have old anker power banks from 5 years ago, still working well....
I've had Anker batteries I've bought in 2014 lasting up to 5-6 years. The issues that start to arise is the following: LED indicator saying how much battery is left stops working, it just cannot be charged anymore, it will charge but not discharge and the last culprit is that it will charge for 5 minutes and then suddenly stop even though the battery still has juice.
That's what I;'ve done as well. I bought the Powerhouse II for when I'm out of my car and purchased their Anker 737 for when I'm out on long forages through the forest @@legendisme8693
Thanks for posting this - as it was the video that finally put me over the edge to just get this backup battery! I've had some anker battery banks for 7-8 years now and while they still work fine, I need to upgrade to a USB-C setup!
I just bought one. This life cycle isn't bad at all. Also, after 3-5 years, I'd probably want the latest technology that would have been developed by then anyway.
@@rickandmorty4-ever61years ago we have Nickel-Cadmium. Then to litium-polymer. To lithium-ion. Now we have Gan technology. And years ago we don't have fast charging, wireless charging. USB C
@@rickandmorty4-ever61 Just a few years ago you'd call a powerbank fast or powerfull if it could output 2x10W or charge with 10W via Micro-USB. Now the new Anker Prime Powerbank can output 250W and charge with 170W over USB-C. It may not be a big step from 20W to 250W for all people, but i wouldn't say nothing changed
I've had an Anker power core 20100 in regular use since 2017, with no noticeable drop in capacity. I ran a dash cam with it for months as well. It's a workhorse powerbank.
@@MyOnlyCommentIsI use mine at work and drop it a lot from high areas since I climb stuff sometimes, been a year and it still works great although it’s all scratched from dropping it. Love the product overall
Great video with great information. I just got 2 of these batteries recently myself with a Black Friday deal. I've already got almost 1000wh on them because I mainly use them to power my laptop during peak rates here in California (about 30wh/hr). I am trying to extend their lifespan by utilizing 80-40% (because it is convenient for me to do so). Tempted to get the next generation of this battery that allows control with bluetooth but I'm going to hold onto these for a few years at the very least. I've been using Anker batteries for years and years, usually donating them to family/friends who then use them for many more years.
I just bought one myself and realized myself the 300 cycles. I knew of how the cycles worked on a battery but still was a little concerned. After watching your video it made me realize the biggest reason I got mine. And that was as a battery backup for my ROG Ally. (I've got plenty of lower power delivery battery banks for my other devices). But the use would be: if I'm ever a passenger going on a long trip and won't have access to a inverter in a car (not very often), a power outage (which happens more often then long trips but still not very often.) A camping trip (which is about as likely to happen as will). So the use will probably last me years. I still have an old Anker 20k mah 3x a-port with power iq bank that charges but the display is dead and another Anker 13k mah 2-a port with power iq that works fine for my other devices. I'm excited to get this battery bank and after watching your video it made me sit and realize that I, like others where probably zeroing in on that 300 cycle part just a little too much. There's nothing to worry about. :)
hi, friend. You still have it, how many more cycles did you get out of it after those 300 cycles? How long did those 300 cycles last? And I also wanted to know if you charged it almost every day?
Rav power 20,000 have performed well also I have 2 of them. One in 2018-19 still going strong. Powers off when not touched but still charges in trickle mode
I wish people will actually get a course in batteries and technology or something. Because 80% of the people out there or 85% of the people don't really know what they're talking about. This guy has a great. Understanding of understanding of batteries. I've worked in cellular for 10 years. Dealing with the battery's reconditioning batteries. Sell on cell phones and working in wireless and being a trade engineer. This guy explains it quite well. I don't mean to be rude to people, but Jesus, come on. People stop panicking most of you will never even getting or meet, reach a full potential and using this device, you probably would drop and break it, or you'll lose it or something like that before you have even reached 300 cycles.
I mean... your typical li-ion cell has a rated life of about 500 cycles, though that's usually quite conservative (80% of original capacity) compared to what most people will be OK with (closer to 50%, probably). Unless you reverse-charge them, they don't just quit on you, rather they gradually become useless. Given the rated continuous load on that thing (which equates to over 6A per cell, if their marketing diagrams are to be believed), a reduced rated cycle life is not surprising in the least. I'm not sure what type of li-ion cell they're using, but it'd make sense if they're high-drain IMR cells, which would also have the 300 cycle rated life. That's the price we pay for being able to draw 140W from the thing. Probably best to stick to smaller loads, if longevity is a concern.
Hello friend, how are you . When you published this, did you use them every day? And I wanted to know if you still have it and how it has hurt you and how many cycles has it taken?
A lithium ion cycle is also considered full discharge and recharge. If you can keep your cycles from 100 to 60 and recharge you will get much more life. 80 to 50 to 80 is the most ideal for a these batteries but I mean we are here to use them not baby them.
Any update on this power bank? I just got mine last week and charged it with an Anker 736 100w and after only 1 cycle my battery health dropped to 99% from 100%. Is this normal? I feel like I got a defective one. In one recharge it can’t lose health already… might contact Anker. Let me know what you recommend please. Thanks in advance!
According to the spec sheet for the cells, it can retain 60% capacity after 300 cycles when charging at 1.5C to 4.2V with .1Amp cutoff (Full) and discharging at a whopping 8C (discharging the entire battery in about 7 minutes) down to 2.5V (empty). Keep in mind that a lithium ion battery is still useful even below 50% capacity remaining. Also know that this type of usage is no where near real world for this battery bank with these cells, only discharging at my estimated average of 2C continuous assuming you always use 140W discharge. Assuming you do slow charging (5 hours) and discharge at about 80-100W the spec sheet claims greater than or equal to 80% capacity remaining after 300 cycles. So yes you can get more than 300 cycles with over 80% capacity remaining if you don’t leave it fully charged for more than 15 minutes. You might even be able to push 500 cycles if you rarely charge to over 80%.
The capacity it retains after 300 cycles is a good thing to include and doesn't matter what it is, should be listed and other brands not listing it just makes anker look bad I suppose
@@rokiedecentra9656 not really. You still need a lot of context to determine remaining capacity. How long you leave a battery full, how fast you charge and discharge and many other factors can give you 50% after 300 cycles to 70% after 1000 cycles for the same lithium ion cell. Sometimes cell manufacturers don’t even have all that information publicly available. Even if a brand lists capacity after so many cycles, they can still claim using long life usage characteristics not representative of real world usage. It would be more ideal for a brand to provide the spec sheet and the consumer determines what kind of cycle life they can expect with their usage.
@@battery_wattage i just noticed your username..... well many powerbanks actively hide the Wh rating so i dont have faith in them sharing that much info but yeah i also want them to be more transparent
You're forgetting another big factor though, batteries have a shelf life too cycles is just one factor for longevity. The state of charge is another an power-banks are a backup form of power so they almost always sit at 100% the most stressed state. Hence you probably expect 2-3 years before the battery degrades to 80% regardless of the cycles. This isn't just Anker but lithium ion batteries in general.
This is why i have a few power banks to rotate i use them for convenience and emergencies had mine for 2 weeks and only have 2 cycles and I went out of my way to get those two cycles just to test this bank if I use this how I plan on using it It will take me maybe a week and a half to drain this battery to where I have to charge it one charge lasts forever when your using here and there instead of stressing it and draining it completely every time you use it if you're one of those people who really use it like every single day and it's your main charging source I would recommend getting the bigger generator style power banks ALWAYS remember You DO NOT have to change to phone to full capacity every time you use the power bank its a waste of a cycle
Depending on the specific duty cycle, results will vary. The trickle setting or only running the pack down to 50% before a recharge. It will last significantly longer. It comes down to stress and dendrite growth between the anodes and cathodes.
Yea I got 7 years old anker 10k, still working just fine. I bought this one because I believe I will get same quality products that will last as long if not more
300 charge cycles is about typical for most rechargeable batteries. Li-Ion do a bit better (I have a Mophie that is now about 8 years old and holds about 80% of it's original capacity, but I don't know how many times I've recharged it though, and it spend about 6 months unused). The only reason I now have to get rid of it is is the battery is starting to swell (no longer sits flat) otherwise I'd keep it, but it's kind of dangerous to use with a swelling battery obviously. Paid about $150 for that one (it was a 20,000 Mah charger with 3 USB-A ports -- no USB-C) but still think I got my money's worth out of it. Hopefully these Anker batteries will do the same. But 300 charge cycle is about normal. If you charge it say twice per week from fully dead, I mean that's still about 3 years of use (104 charge cycles per year). That's probably pretty aggressive usage IMO, and most people might only recharge it once a week if that, unless they're using it to contasntly charge multiple devices each day or week, and running it down, but even at 100 charge cycles per year, it's not too bad, and probably is still better value than a cheap one that lasts only 6 months and then starts to have charging issues. My experience is that for most people, 300 charge cycles on anything will be more than you think, unless you routinely run down your battery every 2-3 days, which some people might, but most people won't, and that those numbers are probably worst case. You may get 350 or 400 charge cycles out of it. The other key is how you charge it. If you charge it when it's 80% full, you're wasting charge cycles in some cases, but if you also run it down to 0% then you're also going to put more strain on it and it may only get 300 charge cycles, but if you do what most people recommend with Li-Ion and recharge when the capacity is between 20-60% then you should get the maximum life out of it that you can, whether that's only 300 cycles or more (probably more). I've seen that some of these power banks and charge themselves while powering something else and while you can still do that, that may also decrease the recharge cycle too, so I would not advise doing that if you want the maximum number of charge cycles. It likely doesn't have a huge impact on overall charge cycles, but not something I would do regularly myself. I would probably just do what I mentioned and let it run down to 20-60% before recharging. Obviously running it down below 20% on occasions likely isn't going to harm much either, but routinely doing that will decrease the life of the battery overall. But even my Samsung Galaxy S10 has managed to survive 5 years of me letting it run down to 20% or less and powering off, and it still holds a decent charge (enough for 1 day at least) now 5 years later, and that's the original battery it had when it was new (5 years ago).
In comparison, normal battery life for Macbooks is around 400-500 cycles. I've replaced 3 batteries on my MBPs over the years and found that 400 cycles equates to over 5 years of use. Usage of this device will be more intesive so I would expect 2-3 years of life should you use it regularly. So about $40/yr. Not bad.
We're on vacation and now it's broken. The display is black and doesn't do anything anymore. It was only charged with an Anker 45W charger. I love the display on the Anker 737 but will probably never buy such an expensive power bank again. And Anker's service is absolutely bad. They have a list of questions where the back and forth takes a week.
I think some people just don’t understand that batteries are consumables. Same as such things like tires, brake pads, wiper blades, and so on. They simply can’t be designed to last forever because of how they function.
Very true but exactly as with tyres (I'll go with the British spelling), brake pads etc, they vary enormously in quality. I guess I would personally expect better than 300 cycles from batteries in a device like this.
I am still using the old anker 26800mah that charges by micro usb. It last long because high capacity to low capacity devices , less battery stress. Im out and about almost everyday. Charges my phone twice(3300mah) still have 75% left. I rarely push it to below 25%.
Yes! The dual micro usb charge still works on mine and it even spent the night in 3 inches of water (on accident) this happened years ago and I still use it to this day. Plenty of drops too, it’s a tank.
My 737 just fried my 45w samsung charger and my anker charger, luckily anker is replacing both chargers and my 737 but still kinda scary that it suddenly started killing my wall chargers
It would be pretty poor from a sustainability standpoint as well as customer satisfaction to physically limit a device. I'm sure you're right that it's just some 21700 cells being well used. I've just checked my device and I'm only up to 70 cycles. 🙂
The Anker power core 20100 is great had it for nearly 10 years still running like it was the first time I got it probably batteries are now shorter from age but not noticeable
Mine got zero cycles. :) It arrived dead, would not charge.... I contacted support and they said they'd send me a solution by email and I never heard back. I just did an amazon return on it. So I think I got the record...
I have an 8 yo jackery 6000 mha power bank with an orange aluminum shell , 4 blue led’s for power level and a single led flashlight, it has lead tough life and is still the go to when my ICRAP 13 needs a quick charge
Maybe a stupid question, but, why do you use a power bank? I mean, why not just plug your devices into the electric socket? Or, charge in the car, or when you get to a hotel when on trips? Just curious?
Is that really a serious question? You do realize some people go on long trips or hikes or maybe even camp somewhere. Literally lots of scenarios where you don't always have access to a wall socket or a car charger...
I ask myself the same thing, I guess if you have a laptop/phone while on the road, away from a wall plug, these would be crucial to have around, it's no longer a matter of convenience but in many cases, it is a cool thing to have portable power with you.
It’s normal for any battery that it will lose capacity over time while being used. I‘ve a 125 Ah LiFePo solar battery with detailed stats readable via Bluetooth and it started losing capacity ever so slightly over time. After 40+ cycles it has approximately 124,3 Ah left. To reach 80 % SoC will take a while. Same with the Anker powerbank. And if some of the safety features will kick in, it would actually be a good thing! Does it have a hard lock at 80 %? Can‘t say yet, but I doubt it. Anker would need very good safety reasons to do something like that. In the EU there are regulations against deliberate obsolescence of products - and the fines are high for companies that disregard this. Anker as a renown brand probably don‘t want to risk it.
Anker make LiFeP0 'portable power stations' those are 300watt hr to even 2kwh in capacity. Those have a 3000 cycle life and that will bring them down to 80% capacity. Ecoflow however seems to make superior products as they give their 3,000 cycle batteries a 5 year warranty.
@@peterc4082 Thank you for your answer. I recommend to read the fineprint of Ecoflow. Not sure if they guarantee 5 years above 80% of capacity regardless of the usage? Personally I would prefer LiFePo over a regular LiIon battery due to the increased safety that comes with it.
@@herrschafts-wissen They're guaranteed for load shedding relief in countries with frequent rolling blackouts. I've had an Ecoflow Delta 2 fail on me about 3 months down the line with maybe 20 cycles max consumed but I had the retailer exchange mine for a new unit. I didn't go the Ecoflow RMA route. The replacement one works fine.
Battery counter in tech product just give me range anxiety My old 2016 macbook pro already in 5000+ cycles But the battery is still fine, yes it doesn't has long standby time anymore But it still usable And they add battery health in iOS My phone on 75% now. And it said 'battery poor' Yes I charge it more frequently but I can still use it for my daily driver Now I never open battery setting anymore
One last thing to mention always discharging constantly at 140w is probably not ideal for the cells and also charging at 140w is not ideal either if you can use 60w pd charger it will be much better for the long term life.
I'm at 149 cycles on my Anker 737 and battery health is 94%. 12995wh total input, 12894wh total output. I usually charge it with a Dell 100w laptop charger and it's used to charge phones (maybe 15w output?) One question I have is if it's a standard 18650 can I not just switch the batteries for new ones later?
Mine stopped working at just 1 Cycle. Yeah, 1. I used it at over 100W power discharge for my laptop and charged it at 65W. and it just started failing to take a charge. It triggered Undervoltage alarm and would not charge, but kept discharging fine until it completely drained. Now it is completely dead and useless. So... I think we should be more worried about the circuit design than the cells lifespan here. I am blown away from the fact that this kind of failure came from a +120€ powerbank.
Funny you should say that. I have a video coming out today or tomorrow on the Anker Prime 200W which failed while I was filming some testing. I had to send it back.
For everyday use that’s kinda true. For users who use it to charge laptops at 100W the scenario isn’t that nice(and also temperatures). Plus if you re using even 60W charger it still gets a little bit hot. And it causes to charge it every day. By that speculation, for a heavy user it won’t have even 80% SoC after one year
One thing I noticed with this power bank it doesn't stop charging your device even when device is fully charged. I charged my s9 tab ultra with this power bank and noticed it says 37% power left. S9 tab ultra took 50% of power to charge and yet s9 tab ultra has battery 11200mah so where did the rest go? I noticed power bank was charging my Hauwei p50 phone even when it's fully charged. Meaning I was losing power in bank. Strange power bank indeed!
Dead cell in the pack most likely triggering UVP. The charge puts the cell up to normal voltage but the second you remove the charge current the voltage drops.
Mine is damaged after a year of use. After about six months months of use, it jumps from 50% to 0% and then one day I plugged it in to my Samsung 45w charger and it started popping and smoking. Never touched it back.
I use the belkin 20,000mAh portable charger compatible with 20w input and output. If I had a 5w charger to charge it with, it could probably last about 6 years given that it goes through 1 charge cycle a week
I doubt it's hard limited. I doubt it would go wrong after 300 cycles, other than it won't perform as rated anymore. That's why they say not to use it after 300 cycles are up.
I have upgraded with a pair of these after many years (very pre covid) with a pair of "dumb" Anker powerbanks. I am not a power user and also do not need to charge the powerbanks at anywhere near the maximum capacity stated. My existing powerbanks have been passed on to grateful family kembers. I charge an android tablet, an android phone and a Garmin smartwatch using the powerbank. I only bought these because 1, I am very happy with my Anker products (I have a larger pack with 2 240v sockets built in for camping with a solar panel, and two pocketable lipstick style packs too) and 2, having state of charge and charge rate info on the screen is incredibly useful. The internet is definitely the place for stupid peopke to make ridiculous claims and hatch incredulous conspiracy theories. The tiring bit is that it takes longer and longer to filter out the chaff. I prefer to buy quality. It tends to be better at what it is supposed to do and is usually far more reliable. And if it breaks the companies are generally better at dealing with these issues.
Don’t store it at 100% and try to not discharge it below 10%. Try to store it at 80%. Tesla know how to look after 18650 cells and they do this. Their warranty on these packs is 8 years. If you can’t get 10 years from this which is not working nearly as hard as a car…. Then there’s an issue.
Mine is on 25 cycles and I bought it two years ago and when it gets to around 20% remaining, it'll bootloop and won't charge anything until its charged back up again. I dunno what happened to it. But it's a bit strange
I wanted to get shargeek storm 2 but I heard their customer support sucks compared to ankler, and that Ankle 737 is better in terms of specs. If I were to experience any issues, I can send the ankler over to their store in my country, whereas for Storm 2 I need to pay for the delivery to the US if I need to return it (that is only if shargeek agreed to the return, I read that they don’t reply to customer after awhile).
hello, I have this powerbank and a macbook pro 16 from 2021 and an asus rog strix g15 and now the question is why this powerbank charges these laptops with me up to 50w if this powerbank has 140 of them?
Depends on how much power the laptop can take over the USB-C power delivery cable. Some are limited to 60W which is absolutely fine for almost all tasks. It also depends on the cable used as not all cables will support 140W, 200W etc.
A cycle is when the entire capacity of the battery is outputted once (regardless of how it's charged) and the battery clocks exactly how much power it has provided so I imagine its just this Wh figure divided by the Wh capacity of the battery.
Espero que esta powerbank sea mejor que la basura del anker 737 26k que tenia una falla en las baterias LG. Fue buena bateria pero con un error fatal, fuera de que no estaba bien aseguradas las baterias y se desconectaban.
But if I only need to recharge it once a week, worst case is 300 weeks, or nearly 6 years. But, I know my requirements for this device - at least at this point in time - so let's say I recharge it every 2 weeks. You get the idea. So unless I have catastrophic problem with this device, it may be the last bank I need, as I'm 67 now.
I do have a question I don't know if you have the answer I couldn't find it anywhere if I charge the battery to 80% and just leave it how long should it be before I need to recharge it again
Well that's a good question. Difficult to answer as there are so many factors involved but only charging to 80% is a very good start as this will reduce the self-discharge rate. After that, it's a guess as we don't know how Anker have made these things. Maybe 1-2% per month of discharge. 🤷♂️
@@tdcattech yeah I learned some interesting things, but I'm still testing so if you don't manually turn off the screen apparently it doesn't go off 😆.at least mine didn't I had it in my backpack for one day it went from 80 to 77 in a single day I was kind of freaking out but then last night I specifically made sure to hold down the button for 2 seconds to turn the screen off. then when I woke up today several hours later it was still on 77 I was under the impression that if idle, it just turns off but I'll give updates in the future maybe in like a week or so. Edit 12 days later battery still holding at 77% making's sure I turn off the screen did the trick in the manual it says that you should discharge and recharge every 3 months if you're going to store the battery bank just thought I would let anyone else who's curious know
You get 300 full cycles from Panasonic or Samsung premium Li-Ion cells, if their temperature never exceeds 25 °C. I doubt Anker uses premium cells. They spend way too much on advertising...
Remember our cell phones after four years dont charge hold a charge so well and also our car batteries will sometime be completely dead and we change those and those cost much more.
If you really wanted too, those 18650s are extremely ubiquitous, so long as there isn't a soft lockout, you could probably replace those batteries. Provided you can open the thing without damaging the case or electronics
If you intend to spot weld in new batteries, I’d probably go with the shargeek options. This is glue together and will likely break, the shark geek just has 4 screws.
Mines lasted over a year and I’ve dropped it from heights of 6ft plus numerous times while at work. Screen scratched up and battery health down only 3% but still works like a champ
Yea Anker is itching to make a customer happy I had a Anker nano power bank go out and they were on it looked up the serial number and everything @@lemon9.9
Life cycle maybe short because it’s from Anker (made by Chinese company) I am sure you can find a higher quality portable charger at the same price if you’re careful enough you can find one Made in Taiwan
I bought this power bank less then a year ago , put on 129 battery cycle and my battery health dropped to a 5% , now i dont abuse it but for god’s sakes someone tell me what the hell is wrong with it ?

One question I didn't get answered from your video.
Does it come with it's own UK compatible power brick?
No, at 300 cycles, it should be at 80%. lifep04 battery have well over 3k before 80%.
I have power Banks from anker that are 5 to 7 years old and they still work perfectly fine
Anker's portable power stations are Lithium iron phosphate and those have 3000 cycles to 80% capacity. Although Ecoflow beat Anker.

I just bought one. This life cycle isn't bad at all. Also, after 3-5 years, I'd probably want the latest technology that would have been developed by then anyway.
Exactly. Things move on quickly. I think people get a kind of 'range anxiety' when it comes to this sort of stuff.

@@rickandmorty4-ever61it has, by a lot.
I've had an Anker power core 20100 in regular use since 2017, with no noticeable drop in capacity. I ran a dash cam with it for months as well. It's a workhorse powerbank.
How did you took care of it?
I don't. I just use it. Charge it up when it's flat. If anything I just charge it slowly.
@@MyOnlyCommentIsI use mine at work and drop it a lot from high areas since I climb stuff sometimes, been a year and it still works great although it’s all scratched from dropping it. Love the product overall
Great video with great information. I just got 2 of these batteries recently myself with a Black Friday deal. I've already got almost 1000wh on them because I mainly use them to power my laptop during peak rates here in California (about 30wh/hr). I am trying to extend their lifespan by utilizing 80-40% (because it is convenient for me to do so). Tempted to get the next generation of this battery that allows control with bluetooth but I'm going to hold onto these for a few years at the very least. I've been using Anker batteries for years and years, usually donating them to family/friends who then use them for many more years.
I just bought one myself and realized myself the 300 cycles. I knew of how the cycles worked on a battery but still was a little concerned. After watching your video it made me realize the biggest reason I got mine. And that was as a battery backup for my ROG Ally. (I've got plenty of lower power delivery battery banks for my other devices). But the use would be: if I'm ever a passenger going on a long trip and won't have access to a inverter in a car (not very often), a power outage (which happens more often then long trips but still not very often.) A camping trip (which is about as likely to happen as will). So the use will probably last me years. I still have an old Anker 20k mah 3x a-port with power iq bank that charges but the display is dead and another Anker 13k mah 2-a port with power iq that works fine for my other devices. I'm excited to get this battery bank and after watching your video it made me sit and realize that I, like others where probably zeroing in on that 300 cycle part just a little too much. There's nothing to worry about. :)
How long does it take to charge your rog ally to full, or do you use while playing it?
hi, friend. You still have it, how many more cycles did you get out of it after those 300 cycles? How long did those 300 cycles last? And I also wanted to know if you charged it almost every day?
i like this guy presenting style, it felt like top gear
True ✔️
Haha, Nah Fr
Rav power 20,000 have performed well also I have 2 of them. One in 2018-19 still going strong. Powers off when not touched but still charges in trickle mode
sucks they got banned
My experience with their 20.000 has been that the capacity is down the drain after 3 years.
I can charge my iPhone 2.5 times with it.
I wish people will actually get a course in batteries and technology or something. Because 80% of the people out there or 85% of the people don't really know what they're talking about. This guy has a great.
Understanding of understanding of batteries. I've worked in cellular for 10 years. Dealing with the battery's reconditioning batteries. Sell on cell phones and working in wireless and being a trade engineer. This guy explains it quite well. I don't mean to be rude to people, but Jesus, come on. People stop panicking most of you will never even getting or meet, reach a full potential and using this device, you probably would drop and break it, or you'll lose it or something like that before you have even reached 300 cycles.
I mean... your typical li-ion cell has a rated life of about 500 cycles, though that's usually quite conservative (80% of original capacity) compared to what most people will be OK with (closer to 50%, probably). Unless you reverse-charge them, they don't just quit on you, rather they gradually become useless.
Given the rated continuous load on that thing (which equates to over 6A per cell, if their marketing diagrams are to be believed), a reduced rated cycle life is not surprising in the least. I'm not sure what type of li-ion cell they're using, but it'd make sense if they're high-drain IMR cells, which would also have the 300 cycle rated life. That's the price we pay for being able to draw 140W from the thing. Probably best to stick to smaller loads, if longevity is a concern.
I've been using mine for 2-3 months, and it is only at 3 cycles. So if I guess this is going to last 30 years then it is not too bad...
Hello friend, how are you . When you published this, did you use them every day? And I wanted to know if you still have it and how it has hurt you and how many cycles has it taken?
A lithium ion cycle is also considered full discharge and recharge. If you can keep your cycles from 100 to 60 and recharge you will get much more life. 80 to 50 to 80 is the most ideal for a these batteries but I mean we are here to use them not baby them.
Mine is at 84 cycles right now and still rock solid at 100% battery health
How many cycles we at now boss?
Any update on this power bank? I just got mine last week and charged it with an Anker 736 100w and after only 1 cycle my battery health dropped to 99% from 100%. Is this normal? I feel like I got a defective one. In one recharge it can’t lose health already… might contact Anker. Let me know what you recommend please. Thanks in advance!
After three cycles I’m at 98% this is worrying me it’s almost like I can only recharge it 100 times
According to the spec sheet for the cells, it can retain 60% capacity after 300 cycles when charging at 1.5C to 4.2V with .1Amp cutoff (Full) and discharging at a whopping 8C (discharging the entire battery in about 7 minutes) down to 2.5V (empty).
Keep in mind that a lithium ion battery is still useful even below 50% capacity remaining. Also know that this type of usage is no where near real world for this battery bank with these cells, only discharging at my estimated average of 2C continuous assuming you always use 140W discharge.
Assuming you do slow charging (5 hours) and discharge at about 80-100W the spec sheet claims greater than or equal to 80% capacity remaining after 300 cycles. So yes you can get more than 300 cycles with over 80% capacity remaining if you don’t leave it fully charged for more than 15 minutes. You might even be able to push 500 cycles if you rarely charge to over 80%.
The capacity it retains after 300 cycles is a good thing to include and doesn't matter what it is, should be listed and other brands not listing it just makes anker look bad I suppose
@@rokiedecentra9656 not really. You still need a lot of context to determine remaining capacity. How long you leave a battery full, how fast you charge and discharge and many other factors can give you 50% after 300 cycles to 70% after 1000 cycles for the same lithium ion cell. Sometimes cell manufacturers don’t even have all that information publicly available.
Even if a brand lists capacity after so many cycles, they can still claim using long life usage characteristics not representative of real world usage.
It would be more ideal for a brand to provide the spec sheet and the consumer determines what kind of cycle life they can expect with their usage.
@@battery_wattage i just noticed your username..... well many powerbanks actively hide the Wh rating so i dont have faith in them sharing that much info but yeah i also want them to be more transparent
Very interesting. Thanks. I have two of these. Love them.
Same here, got one, had to get another :D. Justified it by giving away several of my older Anker batteries. .
You're forgetting another big factor though, batteries have a shelf life too cycles is just one factor for longevity. The state of charge is another an power-banks are a backup form of power so they almost always sit at 100% the most stressed state.
Hence you probably expect 2-3 years before the battery degrades to 80% regardless of the cycles. This isn't just Anker but lithium ion batteries in general.
I bought one a year ago and use it for EVERYTHING and charge it a lot yet I’ve only used 10 KWHs and 113 charge cycles
This is why i have a few power banks to rotate i use them for convenience and emergencies had mine for 2 weeks and only have 2 cycles and I went out of my way to get those two cycles just to test this bank if I use this how I plan on using it It will take me maybe a week and a half to drain this battery to where I have to charge it one charge lasts forever when your using here and there instead of stressing it and draining it completely every time you use it if you're one of those people who really use it like every single day and it's your main charging source I would recommend getting the bigger generator style power banks ALWAYS remember You DO NOT have to change to phone to full capacity every time you use the power bank its a waste of a cycle
Thank you! This is both reassuring and informative!
Really well made and informed video - kudos and cheers!
Depending on the specific duty cycle, results will vary. The trickle setting or only running the pack down to 50% before a recharge. It will last significantly longer. It comes down to stress and dendrite growth between the anodes and cathodes.
i have a power bank with 10000mah from like 7 years ago still runs good. really thinking of getting this one.
Yea I got 7 years old anker 10k, still working just fine. I bought this one because I believe I will get same quality products that will last as long if not more
Jackery explorer 100 plus, 2k cicles 120 euros, 128w delivery, lifepo4, the best solution for the money miles away from the rest.
300 charge cycles is about typical for most rechargeable batteries. Li-Ion do a bit better (I have a Mophie that is now about 8 years old and holds about 80% of it's original capacity, but I don't know how many times I've recharged it though, and it spend about 6 months unused). The only reason I now have to get rid of it is is the battery is starting to swell (no longer sits flat) otherwise I'd keep it, but it's kind of dangerous to use with a swelling battery obviously. Paid about $150 for that one (it was a 20,000 Mah charger with 3 USB-A ports -- no USB-C) but still think I got my money's worth out of it. Hopefully these Anker batteries will do the same.
But 300 charge cycle is about normal. If you charge it say twice per week from fully dead, I mean that's still about 3 years of use (104 charge cycles per year). That's probably pretty aggressive usage IMO, and most people might only recharge it once a week if that, unless they're using it to contasntly charge multiple devices each day or week, and running it down, but even at 100 charge cycles per year, it's not too bad, and probably is still better value than a cheap one that lasts only 6 months and then starts to have charging issues.
My experience is that for most people, 300 charge cycles on anything will be more than you think, unless you routinely run down your battery every 2-3 days, which some people might, but most people won't, and that those numbers are probably worst case. You may get 350 or 400 charge cycles out of it. The other key is how you charge it. If you charge it when it's 80% full, you're wasting charge cycles in some cases, but if you also run it down to 0% then you're also going to put more strain on it and it may only get 300 charge cycles, but if you do what most people recommend with Li-Ion and recharge when the capacity is between 20-60% then you should get the maximum life out of it that you can, whether that's only 300 cycles or more (probably more). I've seen that some of these power banks and charge themselves while powering something else and while you can still do that, that may also decrease the recharge cycle too, so I would not advise doing that if you want the maximum number of charge cycles. It likely doesn't have a huge impact on overall charge cycles, but not something I would do regularly myself. I would probably just do what I mentioned and let it run down to 20-60% before recharging. Obviously running it down below 20% on occasions likely isn't going to harm much either, but routinely doing that will decrease the life of the battery overall. But even my Samsung Galaxy S10 has managed to survive 5 years of me letting it run down to 20% or less and powering off, and it still holds a decent charge (enough for 1 day at least) now 5 years later, and that's the original battery it had when it was new (5 years ago).
I got the 250 watt it’s a wonderful addition to the power bank collection
Is that the new line? Yes, I might take a look at one of those.
@@tdcattech currently shipping in a few weeks/months from anker, do it!!!!! Lol
In comparison, normal battery life for Macbooks is around 400-500 cycles. I've replaced 3 batteries on my MBPs over the years and found that 400 cycles equates to over 5 years of use. Usage of this device will be more intesive so I would expect 2-3 years of life should you use it regularly. So about $40/yr. Not bad.
We're on vacation and now it's broken. The display is black and doesn't do anything anymore. It was only charged with an Anker 45W charger. I love the display on the Anker 737 but will probably never buy such an expensive power bank again. And Anker's service is absolutely bad. They have a list of questions where the back and forth takes a week.
I think some people just don’t understand that batteries are consumables. Same as such things like tires, brake pads, wiper blades, and so on. They simply can’t be designed to last forever because of how they function.
Very true but exactly as with tyres (I'll go with the British spelling), brake pads etc, they vary enormously in quality. I guess I would personally expect better than 300 cycles from batteries in a device like this.
I am still using the old anker 26800mah that charges by micro usb.
It last long because high capacity to low capacity devices , less battery stress. Im out and about almost everyday. Charges my phone twice(3300mah) still have 75% left. I rarely push it to below 25%.
Yeah, I use one of those. Great power bank. Slow to charge but it's fine if you're vaguely organised and just put it on overnight.
Yes! The dual micro usb charge still works on mine and it even spent the night in 3 inches of water (on accident) this happened years ago and I still use it to this day. Plenty of drops too, it’s a tank.
Will be back in a few years for the "replace batteries and reset charging cycles" video
My 737 just fried my 45w samsung charger and my anker charger, luckily anker is replacing both chargers and my 737 but still kinda scary that it suddenly started killing my wall chargers
How
Thank you for the video. It’s excellent and I’m happy that I learned that today.
If this is rated like other power banks, the cycle count is to 80% capacity which just means after 300 cycles, it’s only at 20% less capacity.
It would be pretty poor from a sustainability standpoint as well as customer satisfaction to physically limit a device. I'm sure you're right that it's just some 21700 cells being well used. I've just checked my device and I'm only up to 70 cycles. 🙂
Thank you Todd, was thinking the same.
I trust anker porducts.. i order anker 737 its look nice and good for outdoor use
The Anker power core 20100 is great had it for nearly 10 years still running like it was the first time I got it probably batteries are now shorter from age but not noticeable
Mine got zero cycles. :)
It arrived dead, would not charge....
I contacted support and they said they'd send me a solution by email and I never heard back.
I just did an amazon return on it.
So I think I got the record...
I have an 8 yo jackery 6000 mha power bank with an orange aluminum shell , 4 blue led’s for power level and a single led flashlight, it has lead tough life and is still the go to when my ICRAP 13 needs a quick charge
Maybe a stupid question, but, why do you use a power bank? I mean, why not just plug your devices into the electric socket? Or, charge in the car, or when you get to a hotel when on trips? Just curious?
Is that really a serious question? You do realize some people go on long trips or hikes or maybe even camp somewhere. Literally lots of scenarios where you don't always have access to a wall socket or a car charger...
I ask myself the same thing, I guess if you have a laptop/phone while on the road, away from a wall plug, these would be crucial to have around, it's no longer a matter of convenience but in many cases, it is a cool thing to have portable power with you.
It's a life support machine what if there was a power cut in hotel or even the whole country was power cut
I picked one up in the Oct Amazon Prime Days for $109 CAD, great price!
Also there is an option to open the unit and have the cells replaced new. Whether it’s done on your own accord or by a reputable repair facility
It’s normal for any battery that it will lose capacity over time while being used. I‘ve a 125 Ah LiFePo solar battery with detailed stats readable via Bluetooth and it started losing capacity ever so slightly over time. After 40+ cycles it has approximately 124,3 Ah left.
To reach 80 % SoC will take a while. Same with the Anker powerbank. And if some of the safety features will kick in, it would actually be a good thing! Does it have a hard lock at 80 %? Can‘t say yet, but I doubt it. Anker would need very good safety reasons to do something like that. In the EU there are regulations against deliberate obsolescence of products - and the fines are high for companies that disregard this. Anker as a renown brand probably don‘t want to risk it.
Anker make LiFeP0 'portable power stations' those are 300watt hr to even 2kwh in capacity. Those have a 3000 cycle life and that will bring them down to 80% capacity. Ecoflow however seems to make superior products as they give their 3,000 cycle batteries a 5 year warranty.
@@peterc4082 Thank you for your answer. I recommend to read the fineprint of Ecoflow. Not sure if they guarantee 5 years above 80% of capacity regardless of the usage? Personally I would prefer LiFePo over a regular LiIon battery due to the increased safety that comes with it.
@@herrschafts-wissen They're guaranteed for load shedding relief in countries with frequent rolling blackouts. I've had an Ecoflow Delta 2 fail on me about 3 months down the line with maybe 20 cycles max consumed but I had the retailer exchange mine for a new unit. I didn't go the Ecoflow RMA route. The replacement one works fine.
@@herrschafts-wissen Just to add Ecoflow are Lifepo now, the old non pro ones were LiNMC and had a max of 1000 cycles.

Battery counter in tech product just give me range anxiety

But it still usable
And they add battery health in iOS
My phone on 75% now. And it said 'battery poor'
Yes I charge it more frequently but I can still use it for my daily driver
Now I never open battery setting anymore
any update on how many cycles now and how is the power bank? thanks
One last thing to mention always discharging constantly at 140w is probably not ideal for the cells and also charging at 140w is not ideal either if you can use 60w pd charger it will be much better for the long term life.
Very informative. Thanks mate! 👍
I'm at 149 cycles on my Anker 737 and battery health is 94%. 12995wh total input, 12894wh total output. I usually charge it with a Dell 100w laptop charger and it's used to charge phones (maybe 15w output?)
One question I have is if it's a standard 18650 can I not just switch the batteries for new ones later?
Mine stopped working at just 1 Cycle. Yeah, 1. I used it at over 100W power discharge for my laptop and charged it at 65W. and it just started failing to take a charge. It triggered Undervoltage alarm and would not charge, but kept discharging fine until it completely drained. Now it is completely dead and useless. So... I think we should be more worried about the circuit design than the cells lifespan here. I am blown away from the fact that this kind of failure came from a +120€ powerbank.
Funny you should say that. I have a video coming out today or tomorrow on the Anker Prime 200W which failed while I was filming some testing. I had to send it back.
Its not hard limited.
Every powerbank will slow over time. The data on display is awesome to see.
Have you hit that limit already and gone over?
For everyday use that’s kinda true. For users who use it to charge laptops at 100W the scenario isn’t that nice(and also temperatures). Plus if you re using even 60W charger it still gets a little bit hot. And it causes to charge it every day. By that speculation, for a heavy user it won’t have even 80% SoC after one year
My 2017 20100mah anker is still working well!
One thing I noticed with this power bank it doesn't stop charging your device even when device is fully charged. I charged my s9 tab ultra with this power bank and noticed it says 37% power left. S9 tab ultra took 50% of power to charge and yet s9 tab ultra has battery 11200mah so where did the rest go?
I noticed power bank was charging my Hauwei p50 phone even when it's fully charged. Meaning I was losing power in bank.
Strange power bank indeed!
I'm getting a UVP warning and ot shutdown off. Can only use it as a passthrough if it is plugged in.
Dead cell in the pack most likely triggering UVP. The charge puts the cell up to normal voltage but the second you remove the charge current the voltage drops.
Mine is damaged after a year of use. After about six months months of use, it jumps from 50% to 0% and then one day I plugged it in to my Samsung 45w charger and it started popping and smoking. Never touched it back.
I use the belkin 20,000mAh portable charger compatible with 20w input and output. If I had a 5w charger to charge it with, it could probably last about 6 years given that it goes through 1 charge cycle a week
I doubt it's hard limited. I doubt it would go wrong after 300 cycles, other than it won't perform as rated anymore. That's why they say not to use it after 300 cycles are up.
This is intresting. My powerbank shows 95% battery health after 27 cycles. I use Anker Nano II 65W for charging. What could be wrong?
Сколько сейчас показывает? Проблема решилась?
I have upgraded with a pair of these after many years (very pre covid) with a pair of "dumb" Anker powerbanks. I am not a power user and also do not need to charge the powerbanks at anywhere near the maximum capacity stated. My existing powerbanks have been passed on to grateful family kembers.
I charge an android tablet, an android phone and a Garmin smartwatch using the powerbank. I only bought these because 1, I am very happy with my Anker products (I have a larger pack with 2 240v sockets built in for camping with a solar panel, and two pocketable lipstick style packs too) and 2, having state of charge and charge rate info on the screen is incredibly useful.
The internet is definitely the place for stupid peopke to make ridiculous claims and hatch incredulous conspiracy theories. The tiring bit is that it takes longer and longer to filter out the chaff.
I prefer to buy quality. It tends to be better at what it is supposed to do and is usually far more reliable. And if it breaks the companies are generally better at dealing with these issues.
Mine just hit 50 cycles today still going strong.
Does it has a pass-through?
what would be a good industry standard of delivering Watts to laptops at 65?
I have the anker 747 haven’t used it for couple months went back to it and it not working
Don’t store it at 100% and try to not discharge it below 10%. Try to store it at 80%. Tesla know how to look after 18650 cells and they do this. Their warranty on these packs is 8 years. If you can’t get 10 years from this which is not working nearly as hard as a car…. Then there’s an issue.
Could you post an update on this please? (if you haven't already, and i just can't find it!)

That’s good knowledge and it should be shared. Ty 😊

I wanted to get shargeek storm 2 but I heard their customer support sucks compared to ankler, and that Ankle 737 is better in terms of specs. If I were to experience any issues, I can send the ankler over to their store in my country, whereas for Storm 2 I need to pay for the delivery to the US if I need to return it (that is only if shargeek agreed to the return, I read that they don’t reply to customer after awhile).
Thought for sure those cells 21700 series.
hello, I have this powerbank and a macbook pro 16 from 2021 and an asus rog strix g15 and now the question is why this powerbank charges these laptops with me up to 50w if this powerbank has 140 of them?
Depends on how much power the laptop can take over the USB-C power delivery cable. Some are limited to 60W which is absolutely fine for almost all tasks. It also depends on the cable used as not all cables will support 140W, 200W etc.
I used a safe solution for the powerbank, so since they added it to the 140w powerbank, it should do the trick
My battery health down to 99% after 1 cycle , is something wrong ?
Probably. I still use mine daily since making this video and it’s still at 100% reported battery health.

@@BenMilford no , it's still 99% for now , over 20 cycles
The 300 cycle life is only put out by Anker for liability purposes, it will still function after that. People seem to worry over nothing.
A question
How the charging cycles calculated
A cycle is when the entire capacity of the battery is outputted once (regardless of how it's charged) and the battery clocks exactly how much power it has provided so I imagine its just this Wh figure divided by the Wh capacity of the battery.
Espero que esta powerbank sea mejor que la basura del anker 737 26k que tenia una falla en las baterias LG. Fue buena bateria pero con un error fatal, fuera de que no estaba bien aseguradas las baterias y se desconectaban.
300 cycles? All you have to do is never let it run empty and charge it up to 85% and you'll be fine.
But if I only need to recharge it once a week, worst case is 300 weeks, or nearly 6 years. But, I know my requirements for this device - at least at this point in time - so let's say I recharge it every 2 weeks. You get the idea. So unless I have catastrophic problem with this device, it may be the last bank I need, as I'm 67 now.
I do have a question I don't know if you have the answer I couldn't find it anywhere if I charge the battery to 80% and just leave it how long should it be before I need to recharge it again
Well that's a good question. Difficult to answer as there are so many factors involved but only charging to 80% is a very good start as this will reduce the self-discharge rate. After that, it's a guess as we don't know how Anker have made these things. Maybe 1-2% per month of discharge. 🤷♂️
@@tdcattech yeah I learned some interesting things, but I'm still testing so if you don't manually turn off the screen apparently it doesn't go off 😆.at least mine didn't I had it in my backpack for one day it went from 80 to 77 in a single day I was kind of freaking out but then last night I specifically made sure to hold down the button for 2 seconds to turn the screen off. then when I woke up today several hours later it was still on 77 I was under the impression that if idle, it just turns off but I'll give updates in the future maybe in like a week or so.
Edit 12 days later battery still holding at 77% making's sure I turn off the screen did the trick in the manual it says that you should discharge and recharge every 3 months if you're going to store the battery bank just thought I would let anyone else who's curious know
I'd probably check the cell yearly, ideally.
Hi there, can it be taken in hand baggage in an international flight as per rules?
Yes. It's under 100Wh so should be fine (carry on luggage only).
The information about how many times the display was turned on give me more anxiety that the cycle of the cells. :P
Same😂😂😂
You get 300 full cycles from Panasonic or Samsung premium Li-Ion cells, if their temperature never exceeds 25 °C.
I doubt Anker uses premium cells. They spend way too much on advertising...
Remember our cell phones after four years dont charge hold a charge so well and also our car batteries will sometime be completely dead and we change those and those cost much more.
If you really wanted too, those 18650s are extremely ubiquitous, so long as there isn't a soft lockout, you could probably replace those batteries. Provided you can open the thing without damaging the case or electronics
This battery actually use 2170 cells.
how many cycles have you used to date?
Mine stopped charging after 8 cycles
How is it now one year later?
If it's easy to remove the case, I'll replace the batteries, which I always do
If you intend to spot weld in new batteries, I’d probably go with the shargeek options. This is glue together and will likely break, the shark geek just has 4 screws.
Mine had 75 cycles before showing battery health of 5%. Although anker is honoring its warranty on the device

Life cycle maybe short because it’s from Anker (made by Chinese company) I am sure you can find a higher quality portable charger at the same price if you’re careful enough you can find one Made in Taiwan
Very useful to know. Thank you.
That’s good enough for me
what's the actual state of your
anker 737❓
Great video brother thanks
I bought this power bank less then a year ago , put on 129 battery cycle and my battery health dropped to a 5% , now i dont abuse it but for god’s sakes someone tell me what the hell is wrong with it ?
