Amazon Power Bank Companies Are Lying To You.....

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 :)

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.

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.

[@volcaprojects8333]

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

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.

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.

[@fat_pigeon]

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.

This is the exact reason why I build my own power banks. That way I know their true capacity and that they’re also rebuildable.

[@TheWtfnonamez]

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

[@Asmodeon1986]

Good guide, thanks

[@allezvenga7617]

Thanks for your sharing

[@camelCased]

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.

[@bradleymartin6254]

Coincidentally the ones that were honest did seem the easiest to open

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.

Just FYI - you can buy a USB meter to discharge and count how many mah is drained. Saves disassembling all these 😆 fun video either way

Greetings: Are you giving any of the battery banks away? Thank for the review and I'm glad your safe after such an ordeal. Be Safe!!! Be Blessed!!!

[@ivanvarlev]

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 ;)

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

[@iancalandro8180]

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.

[@Sapient_Pearwood]

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.....

[@tacosmexicanstyle7846]

@@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

[@tacosmexicanstyle7846]

@@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.

now THIS is the video i was looking for. fully prepared to return my power bank based on my findings here.

[@Beau1010011]

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.

[@jacobnathanielzpayag3885]

You should also check the efficiency rating of the power bank like how much of their total charge can actually be used.

[@hardikpshah25]

Thank you bro🧡

[@RyanMartinez]

LOL The ReviewTechUSA "skippity bop mm dottup" intro.

[@corelpo]

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.

[@S_wali]

Wdym power the cell phone? . Are you referring to efficiency cuz that's completely different

[@razgriz1214]

@@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.
