- I opened up a fake apple MagSafe battery pack only to find out that the capacity advertised was not the actual capacity of the battery pack. That got me wondering, who else is lying about their capacity. In this video, we find out the answer to that question.

Hey Guys! A lot of criticism on this video about how I came to the conclusion that some battery packs were lying about their capacity. Let me explain why I did this the way I did. The reason I did not charge and discharge these batteries was to save time ( I am running a full-scale repair business as well as creating these videos). While there is a slight chance the writing on the batteries was fabricated the likelihood of that is not high. Batteries in battery packs are often sourced from different manufacturers than those who create the battery packs, which is why the stamping on the batteries were different from the advertised mAh of the packs that we're being dishonest. The point of this video was to raise awareness of this issue and ensure any individual buying a battery pack from Amazon, Ali express or any similar website thinks twice before purchasing a battery pack with absurd advertised capacities. If anyone would like to charge and discharge the batteries I have taken a look at in this video, feel free to tag me and I will repost the video. P.S - my team and I use two of these battery packs currently and are planning to make one large battery pack with the leftover batteries ( Aside from the pierced one ). Hope this clears up any confusion, once again thank you guys so much for the support and I hope you guys are having a wonderful day :)

If they just said 16000mah, that still is impressive and it's truthful.
True man
It's like they said here's a 16000 MAH power battery and someone higher up said" just lie and double the number. They would have already bought it at that point anyway."
The issue is that if they say higher then they are better than the lower ones. Hence, more sale. If they try to match other then there is more chance that other people will buy other brands.
you can't tell a battery capacity by the print on the back. It's lying just like the titles of the listings and the product boxes.
@@nicks3608 Definitely seems accurate
It is important to note that even if your battery is 10,000mAh you still aren’t going to get all 10,000 you can expect to lose about 10-100 watts from the circuit that is responsible for stepping up the 3.7 volts to 5 volts depending on how well made the circuit is.
10000mah 3.7 to 5v = 7400mah plus the efficiency loss
10-100 watts? Most of thease power banks can't even output more than 22.5w lol.
@@Random_4400 i dont think you understand. He probably meant you are losing 10-100Wh (wich is ridiculus, probably more like 0.1-0.2Wh on modern ones). imagine this, you have a 10000mah battery listed with 29Wh capacity. If it can output 29Watt continuously, it will be able to charge your whatever for 1h. If it can charge at 22.5Watt, it will last for 1.29h. Got it? great. you cant lose 10-100watt as it doesnt tell you how much capacity you lose. watthour/-s does.
Thank you so much for this! Was getting really fed up looking for a power bank but reviews said they were lying on the capacities.
Seeing how the first one has more Watt hour than my laptop powerbank, I already knew something was off. Its good that people are more aware of these scams now
This video will definitely help some people when buying a power bank
Or you could just buy an anker battery charger
It actually did help. Now ima use them every time I go in vacation or to charge my phone if I forget
Power banks are a dying tech..
All day battery + Fast Charging are the solution.

I just hope my anker one is fine (probably is)

Linus: Be very careful, these cells could explode in your face!
Phone Repair Guru: *Casually pokes battery with metal tool*
Yeah. Definitly not a guru.
It gave me anxiety too
Only charged cells are dangerous. Below 10% and you can mangle them as much as you want. Linus said it was dangerous without telling how it’s dangerous.
Don’t get sucked into the fear mongering about batteries, handle it properly and it’s fine.
Prodding a metal spudger into a new battery which should be around 60 to 75% charged is not handling then properly. These packs go up in toxic smoke and potentially flange very easily.
@@jakejakedowntwo6613 ? Did u not see the spark and smoke of the one he poked? Not just 10 % charged... And being brand new right out of the box as shown, no way to be safely sure about the charge %... Not to mention, Best Practices/etc... So, not sure what point you're trying to make, but quite sure you've failed.
I actually own two of the 20000MAh INIU packs myself, and one of them can charge my 4500mah phone 4 times, so I can confirm that the actual capacity is very close, if not the same as the one listed. Their warranty is also great because when I thought that mine broke, I requested another one and they shipped it to me within 3 days. Additionally, the powerbank is nice to touch, albeit it is easy to scratch the soft material, and if you drop it you should say bye bye as I did in my case.
Thanks for the short review, def picking up one soon
if you can get 4 charges (about 18000mah) out from it, it means that the battery is actually around 20ah or more. Powerbanks generally loses 10-15% of their capacity to powerlosses for example the battery is 3,7V and it needs to be boosted to 5V so there is loss already, then the cables etc resistances so you are looking at 100% legit battery
@@volcaprojects8333 but seriously who charges they're phone with 0% ? He might be charging with 5-15%
I am currently charging mine on my power bank, it charges my phone ab 4 times before dying
I have the same power bank, I have a 5000mah phone, and a full charge drains the bank to 66%. I get just under 15k usable capacity.
Load testing is hella easy but seeing them broke open intrigues me as well
Load testing / Capacity recording is not accurate as some power is wasted through heat from the ICs.
@clarkandrews8073 it should still get you close enough to tell if they're lying or not
This sooooo much needed to be done. Thanks for taking on the task for the good of the people.
Lawsuits need to start since false advertising, deliberately lying about a product and not giving the exact product purchased is a crime
When these products and their sellers are based in china that’s pretty hard to do… Best we can do is have them removed from Amazon

Thank you for looking into this. I am so sick of crooks.
This vid is so cathartic. Can’t count how many batteries I’ve got that are definitely not what’s advertised.
Finally somebody who finds out. It was about time. I capacity test every battery I buy for cameras and send them back when they don‘t have close to the advertised capacity. And I sent back tons of batteries. Almost all of them are lying. It became so bad that a company doesn‘t sell anything when they advertise the real capacity. This has to change either through customer awareness or legislation.
You can directly contact Chinese companies and request very high quality batteries and get them shipped. That`s how I get the best 18650s and NiMH for hurricane emergencies. They`ve been honest about their claims.

Thank you for making this video. I'm looking into purchasing one of these and your investigation really helps!
Omg thank you for making this video. Last week I spend around 4 hours each day looking for a power bank for 6 days straight. I was looking for a 20,000mah power bank. Almost every powerbank is marketed with false information and I am grateful for the customers that went ahead to show evidence of the deception. So many of the 20,000mah I checked were truly 10,000 or sometimes even worse 5000mah.
This frustrated me as a consumer and I really wish Amazon can do something in regards to this problem. At the end of the week I got frustrated, and just went ahead to purchase an anchor charger off target.
There are some reputable brands. Anker usually the best but also a bit pricy. I have used brands like Mi, Romoss and Pineng and they are good with accurate capacity and overcharge protection. Unfortunately, there are also fake ones so be careful
I've only ever bought anker powerbanks for a few years, and more recently buying their charging cables. If I've spent hundreds on my iPhone, why would I save 10 on a powerbank that could mess it up?!
Anker is dope
Using Anker for years, saving me many times.
Especially during the days when iPhone has weak battery. Travel to many countries, charge on trains, buses and plane journeys.
Take pictures, videos without any worries afterwards. Happy customer here.
Agreed. Banker has been my go to company for years. Everything from mobile charging to audio that I've had from them has been great.
I've been using my Anker battery pack since 2016 and it's still going strong.
I have Anker, EasyAcc - neither has let me down for like 4 years
I can’t tell you how helpful this video is! Thank you so so much! Subbed❤

10,000 is more than enough. (For A Phone.)
Thanks, I was literally finna ask to see if you could send me the link 😂
Check ANker and ROMOSS powerbanks
Test the Poweradd battery packs,
We should ask those manufacturers who are not lying to make their products easier to open. If you are honest, then you have nothing to hide 😀Anyways, waiting for the second part with the inner battery tests to detect even more liers.
Coincidentally the ones that were honest did seem the easiest to open
Prevented me from cheaping out, you are doing gods work. Godspeed vigilantly
He needed to capacity test the batteries to find out their true capacity.
mhm, they could easily write fake specs on the battery
@@thejpt yeah but that's up to the battery manufacturers, not the companies making the banks. So likely true info.
Exactly! Any battery manufacturer can label their batteries with anything. You can't know for sure what they are until you test them. Lots of cheap cells are fake but still show the "right values" on their casing.
@@dominus6695 Wrong. You're supposed to have quality control and test the parts frequently from each batch (and even the finished products, at least on a sample basis). That's why most powerbanks and non original chargers are crappy.
Exactly, what a useless video!!!
"So I went on Amazon and bought literally every battery pack I could find"
Tests 6 battery packs. I guess lying is contagious.
I heard that, what a tosser!!
He couldn't find more at MSRP
Where I live only 5 are willing to deliver to me so I guess that's what he's referring to?
Did you really think he was gonna every single battery pack on amazon?
He should have tested reputable companies like Spigen, Anker, and etc.
I think its amusing that one of my smallest, most modest, battery packs, outlasts nearly all of my others. Clearly it was the one pack that came with the battery it claimed
Love the INIU power bank. It's the one with a paw on it! Great to see you give the product a gold star. Thanks for the info!

You get what you pay for. This is also extremely common in flashlights with their excessive lumen claims.
06:50 Vroom 🚗🚗🚗😂😂😂
6:51
Thanks for cracking them open for me!
By the way , the "smaller" 10,000 mAH pack is also a higher voltage LI-ion pouch cell (3.85 volts nominal over 3.7 volts nominal) means they can get a little more capacity in a slightly smaller form, granted those higher voltage Li-ion cells typically degrade faster because of the higher voltage.
That is correct and that is science.
What if your phone only supports a lower voltage?
@@mujtabaalam5907 your phone never sees the charger bank's battery voltage, there is a boost circuit to bring it up to 5v volts at a minimum or if it's using fast charge 9, 12, 20 volts or any other modes USB-C PD can do.
USB battery testers are definitely something that are worth having in your kit, especially since you can pick one up for around 20 bucks.
now THIS is the video i was looking for. fully prepared to return my power bank based on my findings here.
This was so awesome! Thank you so much! 😀
Whenever buying powerbank, always always buy those that are branded and from a trusted source. Batteries are just too scary to be meddled with, especially when it's in your bag, pocket or even your car!
3:22 I actually own that one and I was happy to see that they weren’t lying like a lot of other companies
Luck 100
Hey this really helped me after my previous bank (the last iniu you tore open) fried and being not 100% in the know on battery sizes didn't think about the 30ks lying, so thanks!
Most unbranded lithium cell is lying with their printing as well, need to measure it.
Coming from someone who changes the batteries on all their devices, I wouldn't necessarily trust what is printed on the batteries. Most of them can also be flat out lies.
I wish all the thousands of commenters, I mean every one of them, would've stopped to think about this. That's exactly why this is a total bullshit video... don't trust what he says here. All he did was fucking rip apart the battery packs and read the print on the battery cells. Yeah right, like that's gonna give you an accurate representation of their battery capacity... Lol! Bullshit!
There's one thing this video does right: entertainment. That's it. But if you actually want some real objective truth? Go somewhere else. Watch a video from "Gadget Addict" (I think that's his username, if I remember correctly): he actually used a proper fucking meter connected to the battery pack to electrically measure the battery's true electrical capacity! Not just ripping apart the damn thing and reading the print on the battery cells.
I seriously cannot believe some of these commenters actually trust this video for actual legitimate proof... because it's not legit. That print on the battery cells could be lying just as much as the advertisements.
Seriously, the comments that point this out should be getting the hundreds or thousands of likes/replies, not the stupid ones. This should be the case with all TH-cam videos, for that matter. The comments that actually tell it like it is and call out bullshit when they see it are the ones that should be getting all the attention. But then again, we live in a society that's afraid of being brutally honest and telling things like they are and calling out bullshit where needed. All they want now is to be "entertained" regardless of whether it's legit or not.
You are doing a huge service to the TH-cam community! Please make more battery videos. Amazon reviews are completely unreliable anymore..
He's certainly not doing a "huge service" with his totally unlegit testing methodology. Come on, you really think just ripping apart a battery pack and reading the print on the battery cells is gonna give you an accurate representation of the battery capacity? Bullshit! That print on the battery cells could be lying to you just as much as the advertisement. You need to actually do an objective test, using a meter that's actually measuring the electrical output of the battery, if you want to know the true battery capacity. This guy did none of that whatsoever.
In summary: this video is bullshit. It just is. There's one thing it does very well: entertainment.
thx so much man i was incredibly paranoid on amazon while searching for these, absolute relief you confirmed which ones are legit
Thank you. We need more out here like you.
Really informative, thanks for taking so many apart! Please be more careful though! It's so easy to puncture those batteries with a metal object and start a fire
Just taking apart a battery pack and fucking reading the print on the battery cells is not at all an accurate metric for determining the battery capacity, though. That's exactly what this guy in this video did. So... this video is bullshit. That print on the battery cells could be lying to you just as much as the advertisements. You need to actually get an objective measurement using something that's actually measuring the real electrical output from the battery over time... that's the correct way to do it. Not by reading some pretty print written on the battery cells!
Yes, I've said this before in other replies to other comments... and yes, I will happily continue to say it. Because... this video is bullshit. The guy's just wanting you to click on his fucking Amazon affiliate links; pretty common with these youtubers. And he does this at the expense of proper objectivity; pretty common with these youtubers.
Great video tho, actually it's not just the battery themselves,
The quality of the batteries plays a HUGE role in the power bank's capacity,
Also there are other factors such as the charging board efficiency too
@Wedak Tofi sussy
I purchased 2 20000mAh iniu banks after watching this video. Love them so far. Thank you so much for this
You're doing a great job. Keep it up. This is the way
Makes you wonder if there isn't any sort of agency that checks these products before they can be sold in a country and then slaps their label on it so we know it's good...
I definitely notice battery pack not being as exact as advertised because whenever I use it to charge my iPhone I would often count how many times I’ve plug it in and most of the time it’s much shorter than the supposed battery pack content.
you know 1000 mah from battery wont charge 1000mah to your phone , you know why?
@@VJETRAwhy?
@@rafiihsanalfathin9479 1000 mah is 4 volt on power bank battery , so it need it to step up the voltage to about 5 volt to charge other battery that mean about 200 to 300 mah is converted to extra volt , and the converter also take some power itself . Plus your phone may use some power during charge so you Wont see 1000 mah increase in your phone.
Thank you so much Bro... this saves me so much time from mangling powerbanks on my own. Thumbs up 👍👍
I found this video by searching to see if somebody broached the topic. I bought 20,000 mah battery bank that was about the right size to actually have it - thinking I was going about it in a smart way - and in reality it topped out at no more than 4400mah. Super upsetti
My claims to be 10,000 but I think it's somewhere around 6800 to 8000
2:03 GENIUS
In some cases it’s not lying. Companies just keep consumers ignorant about battery information. I hate it when even honest companies only use mAh when they should be using Wh. Some power banks base their mAh on the standard 5V output instead of the actual battery cell’s nominal voltage, plus different battery chemistries and factories can have different energy densities.
I agree that power banks' capacities ought to generally be specified in (m)Wh. However:
> Some power banks base their mAh on the standard 5V output instead of the actual battery cell’s nominal voltage
x mAh @ 5V is *more* energy than x mAh @ 3.7V.
Your video was well done and ripping these companies a new one was so refreshing to see as they have mostly been lying to us for so long they believe there own sales pitch
I believe they don’t think we even went to school as well in being able to read and test things for our self.
Thank you for your video it was a breath of fresh air so have a good safe and good Christmas.
And did you not stop to think that maybe this video is itself lying to us?
good video, nice to see people smart enough to know when they are being lied to
You should definitely get a battery drain tester if you plan on making these videos. You could have returned all those powerbank after testing the capacity if you hadn't opened them
He Can send it back for a full refund still. Because not as described and he is eligible for full refund in rhat case
the issue is that the 10000mah the battery has not not what the powerbank gives due to losses so the only real way to do it is to open it to see the cells inside
You could wire the output of the Vurt battery to a shunt and volt meter. Then track the level of the battery over time.
Good, interesting video. I understand your approach, it is really about honesty by the supplier, and some are blatantly dishonest. Like your presenting style, clear and concise and no "look at me" stuff. Now subscribed. Well done.
And did you not stop to think that his approach of "testing" these battery packs is actually a bit flawed?

But I was still skeptical if there lying...
Thanks for clearing that up!
I feel attacked!
I am using the battery pack you reviewed first! OH my goodness my emotions!
Great video. Please take in consideration that the battery also needs to power the cellphone while it's charging, so it will never be 1:1 ratio. If your phone has a 4000 mA battery and you are using a 8000 mA portable battery, it won't charge it twice to 100%, it will fully charge 1x time and ~40% on the second time.
Wdym power the cell phone? . Are you referring to efficiency cuz that's completely different
@@S_wali i think he meant to charge the phone you need higher voltage than the cell you're gonna charge.
Power Bank usually state the 3.7v to rate the capacity but that need to be changed to at least 5v to be able to charge.
Hence why it'll never be 1:1 ratio. But if the pb is genuine, the total power (Wh) should be close or same.
@@razgriz1214 plus the phone gotta step that back down to the cell voltage
Wait they sent the entire order in one box ?!? Since when does Amazon do that
It's a setting you can do with Amazon to consolidate packages. You have to go into settings. It used to be an option during checkout, but they buried it.
Wow you really opened my eyes thanks mate no wonder I can't fully charge my 5000mah phone using 10000mah powerbank.
I think it really boils down to whether the companies have a name, and if they want to keep that good name.
I mean, if a power bank is unbranded then they have absolutely no reason to be honest because you can't really do damage to the company if nobody knows who they are.
But thanks, this video was really helpful.
I was already suspicious of those unbranded 40,000-50,000mah power banks, so I definitely won't be buying one now!
Watching you rip into these hurt me so bad man. All you had to do was order one of the little USB dangles to monitor the power input/output and voltage. You'd have been able to figure it out without having to destroy the packs.....

Thank TH-cam for removing the damn dislike button. So glad I wasted 2 minutes of my time on this attention seeker -_-
@@Norinia The iPhone 13 Pro has a capacity of 3095mAh, so if your power bank is truly 30k you should get NINE full charges with some power left over.
If you’re only getting five charges, then your capacity is likely closer to 15,000mAh. This video isn’t fake, your battery is fake lol
@@ethylg7572 The numbers on the battery cell are always correct per the strict regulation. These are just generic LiPos put into power banks manufactured by third parties. These companies can print whatever numbers they want on the plastic casing and retail packaging, but they can’t do that on the cell itself.
Unless you want to sit and watch a discharge cycle for hours, the only way to find true capacity is to look at the cell. The capacity readings from the PCB use voltage, but voltage doesn’t decrease linearly over time so these are usually wrong.
@@Norinia this video has 1.1K dislikes at time of replying. Get TH-cam Vanced.

Great work bro , thanks for the info, keep kicking `em on da nutz
You are an honest man. God bless you.
The ones on ebay are even more rediculous. I have often messaged sellers asking them how their battery pack that's the size of a poptart can make three times the capacity of a Tesla Model X battery.
They make up some "marketed capacity" excuse whenever I have done that.

LOL The ReviewTechUSA "skippity bop mm dottup" intro.
I bought one called charge Worx w o r x, you can charge it by solar or just buy a light. It in my duffle bag for three years I had forgotten about it, and it's always fully charged. I've had it for years I don't remember where I bought it but it's the best one I've ever had
It's been 9 days since this video is posted. I checked the Amazon listing for these power banks. Surprisingly, they are all still there. I checked the latest review on the product, nobody mentioned about lying capacity.
To be fair, many people aren’t aware of how long they should actually last.
Hear me out! Crazy idea here... if you wanna save/use the batteries and still properly test em' - just go ahead and use a battery tester. It would have been a lot cheaper and A LOT more environmentally responsible! These are now just e-waste.
Edit: Oh, and you can't always blindly trust the print on the battery pouch... trust me ;)
Use a multimeter
@@limegreentechnologies8803 please explain wtf a multimeter is going to do
@@jimmysyar889 measurements
@@limegreentechnologies8803 yeah what measurements
I've seen a youtuber that uses a portable meter for usb applications that display voltage current and total capacity of the powerbanks. He totally drains them with a dummy load simulating normal consumption. Took a bit of time to perform but good experiment to debunk advertised capacity
"Im gonna try as hard as i can to not to break this one"

You earned a subscriber and taught me something important. Thank you.
I actually measured that first battery pack (well, the version without the wireless pad, but otherwise identical) Mine came out to 48Wh. Way less then the advertised 113Wh, but more than what the pouch inside is rated for. Maybe there's two pouches in parallel? 48Wh was at a ~10W draw over the USB port. I only paid about 30euros for the pack which is fine for 48Wh. My biggest gripe is that it doesn't want to charge with half of my USB-C chargers. Oh, and I wrote a negative review on amazon.. which got declined.
This was such a helpful video. I’d love to see more videos that validate Amazon vendor claims.
But you don't validate anything by just reading the fucking print on battery cells as if that automatically gives you the true battery capacity. That's exactly what this guy did. Come on, don't be fooled. The guy in this video never once measured the actual electrical capacity of the batteries! So... as I've said before, and I will happily continue to say, this video is bullshit. There's one thing it does well: entertainment. But if you actually want some real objective truth? Look somewhere else. That print on the battery cells could be lying to you just as much as the advertisements.
this helped a lot thank you very much for risking your safety to help us buy smarter.
yo your my fav youtuber i learned how o repair phones from you and wanted to thank you for all your efforts
I appreciate that!
You're just checking the labels, not testing if they actually hold the charge.
He did basically no testing (very poor video) as all he did was read off of the "printed" labels on the battery packs which are well known to be re-printed or overlaid as a sticker to cover up the original markings. He also doesn't account for voltage conversion losses or that the mAh rating is calculated on the native 3.7V Lion/LiPo voltages.
You should also check the efficiency rating of the power bank like how much of their total charge can actually be used.
Thank you, your vides are a huge help! cheers man!
I bought a Road Proof Superboost Portable USB Battery Charger, to charge and operate various electronic equipment. It has lasted me a long time I am really happy with my purchase. I had also bought a Duracell Jump pack to start a dead car battery, it was junk (even the alligator clips were too small to stay on the battery posts (and you cannot swap the the clips out, as they are embedded in the unit)
So since I bought my first 20k battery pack, I have also tested all my battery panks... I've also found that most of them are under the advertised amount. My 2 20k ones have been 17k and 14k respectively. The 10k ones have been at around 7k and 4k, and some even 1k. I believe it often also comes down to the charging speed, but in the end, it does often depend on the cell quality
Cell quality yes but also the circuit efficiency+ 5v vs 3.7v
batery pack is on 3.7v and it needs to be converted to 5v before it can charge your device
That's why i always look at the Wh not mAh.
The 20k one usually state 74k Wh. So 74000:3.7 we get 20k.
But to charge it needs to be 5v. 74000:5 we get ~15k not counting the efficiency due to heat loss. This is the capacity that you're gonna get.
Your powerbank is genuine if you can get at around that 15k and even better if beyond that.
and it could also be that it shows the cell capacity but not how much is a buffer to be used to preserve cell health kinda like how ssd's and hard drives clock a little under advertised capacity due to file systems for the drive taking up space.
It's actually really easy. For instance a 15000mah power bank at nominal 3.7v is in fact a 15000mah, however when you charge stuff at 5v (over usb) it's more like 9000mah. Banggood actually has a really nice blog post about this.
Thanks for sharing
Wow, this was hard to watch. Glad you weren't hurt in the process, but ngl I had to cover my eyes a couple times
Thankyou ❣️ so much for such effort
