Best overview of a powerbank I've ever seen. Thank you!
Waiting for this one. Thanks mate. Most wanted review ever 😍❤
That was the best review i ever saw on a powerbank. Really in-depth and professional. Thanks! :)
I bought the 100 W Zendure. Even it is more expensive, it uses better battery cells and offer a repair service. With the Anker, the day it fails you find yourself with an expensive doorstop.
Thank you for the great teardown and component analysis...
I cannot wait till the EU mandate of replaceable batteries in consumer electronics.
2027 cannot come any earlier.
I really enjoyed this video! Super thorough and you went into it all! Keep 'em coming
Superb teardown, details and info. Truly excellent, thank you 🎉🎉👍
Our pleasure!
Your channel and concept is amazing!!!!!
I just bought one of these, waiting for it to come in the mail. Excited to see what it looks like inside. I am wondering what the prospect for changing the cells would be in the future.
Wao this teardown we have been looking for a long time
Awesome teardown
Awesome teardown review! How would you rate the difficulty in replacing the batteries if they dont hold the same charge compared to new ones anymore?
I totally appreciate this teardown, and I've charged my 16 inch m1max to 80% in 40 minutes (sleeping, not with active use) with this battery, but knowing that this costs €150 for a battery because I bought it 1 month ago, makes me cry a little that you had to rip apart such an expensive piece of equipment :D hahah
Prepare to cry again: These go on sale for $100 occasionally
@@74862 isn’t that always the problem? You buy something and then a month later, it’s on. Big discount sale 🤣🤣🤣 dammit!!
This is my favorite power back thanks for the in-depth review 👍🏽
No problem 👍
I've been waiting for you to review that new PD powerbank from Anker. Good review! I'm considering buying this. Hopefully you'll also review the new basues GaN 140w charger.
Wonderful video fantastic review :))))) big fan of your videos now ;))))
Love to see powerbank series that can after being teardown can easyly attach it back
That's some serious kit!
Very well explained
Wow!!! 20v/5A, 28v/5A Awesome
I just got one of these two days ago it works great
I got this one because it has a separate USB C that can output the full power but only output my phone will sometimes try to fight with a power bank that has a common in and out port where it sometimes the phone will try to charge the power bank but with the output only port I could charge my phone without it being able to fight back
Real Good!! Video - Thanks
Very nice review. it is great
Thanks for the video, I would like to ask if you know if it is possible to charge a mobile phone and charge the powerbank at the same time?
What does the hidden switch do inside. Also is that a way of clipping it open without tearing it apart like you did ?
It's a nice device, although it's important to remember those cells do not live forever and needs replacing at some point. My 18650 cells always die at about 6 years of usage.
Hey mate, have you taken apart any of the Anker Fusion? Cheers
Interestingly, it does not use a switching power with a high-frequency transformer but a bulk-boost chopper, is that normal on PowerBank? I think that bulk-boost has less efficiency.
Are you able to check the new goal zero AC battery charger?
good video thank you
wow, interesting, is it possible to DIY something similar with nice screen from market available PCB?
Looks huge to carry about
Best Anker 737 review ever!... Very very interesting! Thanks a lot!...
My pleasure!
Thanks!
Great video
wow this thing is a beast...
Me dio una pena que destruyera asi una buena powerbank, un poco mas de paciencia, unas gotas de alcohol o thinner y ya estaba listo. Fuera de eso excelente explicación de componentes, solo por eso se gano un nuevo suscriptor. La Anker powercore elite 3 tiene unas celdas que fallan muy facil, veo que aqui han cambiado de fabricante a uno que la verdad no reconozco espero que sea mejor que LG. saludos.
Can you attach more batteries to it pushing the battery capacity to 80,000mAh ?
I am thinking of doing it and 3d print a new shell for it too.
When will Anker Prime 1340 and its analysis be available?
Is there a button combination to actually reset or hard reset this power banks software?.
I'd love to see additional testing of cells itself to see how consistent they are in specification, with 18650 I had lots of bad luck with chinese batteries, especially when introduced to temperature fluctuations, mostly outside use in winter it just dropped far below 3V
Yes. I have another anker power bank using 21700 but they are lg
These are 21700 batteries
Not all chinese cells are bad. Anker is a reputable brand. I am pretty sure they are sourcing these 21700 cells from well known makers. The general bad 18650 cells are those ultra fire or similar named stupidly high capacity claimed cells..
These Lishen cells are pretty good quality, on par with Samsung 40T but expect a lot of 100/140W PD charging to really the life cycle count. Cells that are driven near their max will degrade much faster than standard 800-1200 cycle life. Check the datasheet to see if Lishen goes into detail or just gives one number
@@ericklein5097 Capacity ≥ 2,400mAh @300 cycles
(60% of the standard capacity @ 25℃)
- Charge: 6A, 4.20V, CCCV 100mA cut-off@ 25℃
- Discharge: 35A，2.5V cut-off @ 25℃(80℃ cut-off)
Is it possible to take it out and put it back in? The USB C that charge it stopped working and I’d like to repair it as it’s a shame to throw.
Is it possible to reassemble?
Nice good its so verry good job review Totalitas
If I have a light with 45Wh and 12V, how long does it take to consume the power bank? thank you
Anker is one of the best power bank manufacturing company.
you have diagram electronic circuit for this power bank ?
I have this PB, unfortunately the screen is faulty, looking to replace it. Does anyone know the part number?
just wondering, is there any batter management as far as balancing leads to help maintain the batteries health?
Yes, the lower board does all that. The cells must have balancing or they will eventually drift apart and give you less and less capacity as the charger stops working when the lowest cell hits a predetermined low voltage cutoff.
I also found and bought the following product baseus elf 65w 20000mah powerbank, I'm really happy with the built-in type c cable, very useful. Apart from that, I couldn't buy it because the price is a bit high 🙃 Baseus 100w 20000 mah powerbank is also available, a very stylish design and a useful product.
i have it and it charges my mac only for 2700-3000mah with 75w
Looks huge, next time add a 0.5 liter Coca Cola bottle for scale.
It would have been more useful for this thing to come with a 200W USB C charger.
Anyway, I guess you can "charge it" at 140W while having another device draw 140W from it.
will there ever be 240w power bank?
Hey why don't you guys review remax power bank?
Please do the 60000mAh power bank from remax
plzzzzzzzzzzzzzzzz
Love you
device was cool
nice
what is the device you use to test usb-c cable? i have a ton of usb-c cables and need to test them for maximum watts etc.

Wow!
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.
Which LCD screen is that?
Very geeky in the good way but will be better if you can translate those engineering info into comments about how safe this power bank is.
is this made by ZMI ?
I was thinking about getting this but now that I see the batteries can’t be replaced without destroying it I’m not sure I will. Too bad you have to toss out a $150 battery bank all because it can’t be opened in a nondestructive way
why would u ever want to replace the cells?
@@bachoyaryarashvili2793 because they can go bad quite quickly while the really good electronics driving the powerbank would probably work for decades.
@@geraldh.8047 Yeah it's unfortunate.
I know, right? I wish I saw this before buying one myself, then I would've bought a shargeek storm 2. They're so much better repairability wise.
Thanks for pointing this out. Going for the Shargeek 2 now instead.
A beautiful charger. But sacrificed for SCIENCE!
Hi there, I have a favor to ask you for. I watched your video and opened up my defected anker 737 today, I didnt have a grinder so i had to pry it open with a spudger. I succesfully opened it up but in a process i broke its display lcd. I was wondering if you still have that display with you somewhere sitting and if its not in use can i buy it from you ? I'd really appreciate it and it might help me revive my powerbank, since I kind of figured out what's wrong with it, it's b2, b4 and b6 batteries are under voltage, rest of the 3 cells are around 4volts but these 3 are between 3.01-3.17. they discharge to less than 2.5 very quickly and the powerbank shuts down automatically. I was initially thinking it might be the firmware issue but um its not, Maybe just a BMS and these 3 cells are the main issue here which i'll try my best to fix on my own but i broke my display.
Please let me know if you read my comment, if i could buy your tore down 737 display. i have very low hopes but um yeah.
have a good day sir. :)
Hi, I appreciate your message and the effort you've put into trying to fix your Anker 737 power bank. I'm glad to hear that you found my video helpful in your troubleshooting process.
However, I must apologize because the display from the Anker 737 that I tore down in my video is no longer available. It was a part of a teardown done quite some time ago, and I don't have any spare components from that teardown.
Best of luck with your power bank repair, and have a great day!
What parts are GaN?
Why not battery 5000mah x 6 ?
This model available bring with hand carre in flight/airplane?
Yes, it's less than 100wh
Now i want to see if you would tear down the Anker 3-port 27,650mAh 250w version. Thanks.😂
There are some things u say which are not accurate nitpicks tho, (thermal pads dont realy dissapate heat the used to conduct it... etc)
Thermal pads can conduct the heat and then, the heat will be dissipated faster.
That's wild to me that a USB cable can be rated for 140 watts.
there's working cables that can go up to 240w now
@@HearMeLearn like the one in the video, that clearly are a 240watt rated cable when its fitted with an Emarker claiming it can do 50v 5A 0:54
Its an 240 watt cable that come with this powerbank, but since its a 14w max product.. they just posted the same wattage on the cable, but its inner chip says its a 240watt cable., and it does feel like high wattage cable it as its annoying as f..from all the heavy amount of strains inside that makes it quite stiff...
Just sted it on the Fnirsi FNB58 BT USB meter, it labels it also as a passive, 0-1m cable with a rating of 50v and 5A, so a max of 250watt. but its a short cable at around 60cm
Maybe you know the reason why the message is displayed SCP ?
You are a nice person
Hello, I am Abdul Salam. I work in phone maintenance. I had a customer who needed to replace the USB-C1 port because it was broken. The power bank was opened well and I took out the motherboard and worked on it. I replaced the USB-C1 port, but the device no longer worked after that, and a notification appears that says The temperature is very low and the battery percentage is also zero. What is the solution? I do not know that there is a diagram that shows me information about the IC along the impedances and resistors.
Can anyone help in finding a solution and repairing the power bank?
👍👍👍
The only problem I have with Anker is that it's too pricey and too small capacity
👍
After my son accidentally dropped my 737, the screen broke. Anker informed me that they do not offer any repair options. Now, I'm weighing the cost of repairing it myself versus buying a new one to see which is the better option.
Everything has become disposable.
Shame how difficult it is to open, makes it absolutely unrepairable without destroying it.
6A max cell current? That will be 6A at 18v when the cells are low and under load. 140W output will then be out of spec for the cells...
Sounds abotu right, mine had ports cutting out and power delivery going down when 2 devices were plughged in no matter the ports used. It also had issues withthe steam deck and would require a full reboot (by leaving it for 10 mins unused) to try and get the right wattage. but as soon as you plug a 20w phoen in the 38 watt charge went down to 22w... Was an absolutely awful product, I showed the videos of the poor performance and anker's response was this is normal function. I find the 140w number extremely misleading
There is "Continuous Discharge Rating (max): 35A / 45A with 80°C temperature cut" in the LR2170LA specs. It's strange that only 6A was announced in the video.
It's possible it can go beyond that 6A spec for short periods of time
Basically a GAN Charger but with batteries 😃
Yes
Better put it back together again
😂
Any idea what that hidden switch does?
It's only used in production and assembly
@@ChargerLAB yes but inquisitive minds want to know what it actually does!
Can you bring this on a plane??
Yes
How to deal with this SCP?
I would buy one but the persistent fear of happiness gets in the way .
You FORGOT to mention that Anker doesn't give you a +watt adapter.
How many of us have a nano adapter?
That's an extra £50.
They should have included the adapter for the price tag.
Got mine yesterday & had to charge it overnight at 10w=8hrs.
My 737 lasted a few weeks got it to about 7 cycle's. Put it on charge the other evening it said charging came back later to find 0% charge. I thought thats strange. Anyway it turns out that the battery thinks it's temp is -40 and it's basically given up saying it's got 5% battery and 0 cycles on the detail screen 5% on the other screen. Won't take a charge and won't give a charge. I'm really not impressed with such an expensive piece of kit doing this so quickly I wanted it to last me years at that price. Seems like they've overcomplicated things with the software and it has glitched displaying incorrect information. The next day the screen was completely dead as if the battery is thoroughly drained itself will not take a charge or anything. 👎
Those Lishen cells are essentially Samsung 40T clones. 35A/45A with temp cutoff. A 6A cell would stand no chance powering this power bank.
Ahhh Chargerlab meant 6A charge current
I got this power bank a few days ago after only three charges and and discharges, it stopped working. It displayed a 50% charge. I discharge it completely, since then it won’t charge with anything. Got a couple of pictures if anyone is interested.
I‘m so sorry about that. You may contact Anker to get a refund or replacement.
@@ChargerLAB the battery was bad for eBay at a lower price price. It worked fine 3 charges. Anker doesn’t want to help me in this matter.
@@grusamgrid so you bought a known bad (defective) device? Why?
@@geraldh.8047 what I meant to say is “bought from eBay”
@@grusamgrid then you should complain at eBay and open a case. With eBay in case of conflict they tend to mostly side with the buyer. Should be no problem if it was bought recently (and since this is a very new device I would guess it was bought recently).
The batteries should be connected in parallel to reach the 24000 mAh , not in series
Yeah, I don't exactly get what they are doing here, there has to be more to it or you would have 4000mAh capacity. There has to be some type of switching going on.
mAh it's been a marketing measure unit for a long time. What do you care how they are connected inside if voltage that you get is regulated and more to it - not 3.7v for which mAh has been calculated...
@@neve_dimka Because I'm curious, because I work in the field and have a very expensive lab setup, because I enjoy it. That said, this is just a video I watched real quick.
@@pietromoopy2010 my comment was to Enelyson Fields. Anyway it answers your question too - mAh written on a box is for marketing reasons. The general public is accustomed to mAh, so manufacturers keep presenting their products this way.
@@neve_dimka Oh I agree it's a useless measurement.
Can i repair my apple 20 waTT Adapter
@chargerlab
We won't recommend you to do this.
The teardown convinced me never to get this, basically not fixable. Cells should be replacable without destroying the thing. Thank you for the review as always, and shame on Anker for the absolute trash design.
A bit disappointing that for the price you only get generic cells
Provide schematics also 😂😂
I haven’t seen a commercial powerbank with “removable” batteries
until now
Checkout 'LAER'
Wake me when there's a power bank that can output the full 240W EPR range.
So it can be discharged in about 20 minutes when powering a gaming laptop?
@@willng34 To be entirely fair, that's about a 50% extra battery life for something that has a nominal battery life of about 40 minutes, and that might just be enough to get someone through something. Granted, you can also swap the USB power bank out halfway without shutting the laptop down, like you used to be able to do with multiple laptop batteries in the good old days
25 minutes at Airplane maximum capacity
@@tsujimasen indeed, last time i check TSA still limit 100Wh (or 27000 mAh) for power banks
And I thought a power bank just has two wires positive and negative straight to my device...
If I plug this 140w device into my 40w Apple iPad Pro… what happens? 💥?
your device communicates with the charger and it would use only as much as it would need at the right voltage and amperage, so no boom
@@run00n0 - Cool! So I can plug my iPad Pro directly into a wall socket with no adapter. Thanks!
@@run00n0 Nonsense. There is no communication for that purpose.
Clearly the basics of electricity are not understood. I shall explain.
When a power source specifies a watt figure, this is the maximum power that can be drawn from the power supply. It does NOT mean that the power source will always deliver 140 watts regardless of what you connect to it.
For voltage sources, which this is (as opposed to a current source), a set voltage is output. Now, the load, the thing the power source is connected to, will draw current and how much current is drawn is entirely up to the load (within limits which are set by the power source).
So the the power drawn is a combination of the voltage and current (P=V.I), therefore as the load or different loads draw different amounts of current, the power drawn from the source also changes.
So if you connect a 140W charger to a 40W IPad, then as long as the power supply has the correct voltage for the IPad, then there is no problem, the IPad will draw the amount of current it needs, and the power source -the battery - can deliver it (because the requirement of 40W is less than the maximum power of 140W the power source can deliver).
No need for any communication between battery and IPad.
Now, USB-C supports multiple voltages, unlike earlier versions of USB which are all fixed at 5 volts, so there is a danger that too high a voltage could be delivered to the load, to the device being charged, and that is then where communication comes in, to ensure that the correct charging voltage is used.
@@deang5622 Are you new to this? There is an entire communication protocol set up for Sources and Sinks to negotiate a voltage.
Source: Hi I can do X Y and Z
Sink: Hi I can accept X and Y so I will take Y
Source: Sending Y
This missed opportunity here it to collaborate with another TH-camr that works with wood, or epoxy resin etc. And re make it into something cool. Like built into a piece of luggage. A table. Or a bike.
Side note. WTF the world needs to ban non repairable electronics ASAP. If every phone had a user replaceable battery. And every consumer electronic device was user replaceable batteries the world would be a much better place.
looks like a small brick
Like watching an autopsy. 😢
