A look inside a fairly common USB power bank sold on eBay. Note that I do not recommend that the output is loaded above 1A as demonstrated in the video, as 140C+ is way too high for semiconductor components!
Other than the slight undersizing of components for full 2A output, the unit is actually quite well made and fits a very large lithium cell into a rugged alloy case.
Jack Youngs pointed out that if the unit is using a buck converter during charging then the input mAh I measured is not going to reflect the cells mAh capacity, so it will actually be closer to 5Ah.
Here's a general search link for eBay.com.

Don't forget that the seller would've spotted your UK address so would have sent you the UKCA version of the product. According to footage from The I.T. Crowd on fire extinguishers, UKCA standard devices are supposed to catch fire. 🔥🇬🇧😋
Aside from that, the enclosure looks like it was originally intended for cheap external hard drives. It looks just the right size for a 9mm drive and a SATA-USB bridge circuit to go with it. 💾😇
Some brilliant quotes in this video. The one about poking a lithium cell with a sharp blade made me laugh out loud!
"It's like opening a bomb" and then "Oh, that came out just a little bit easier than expected". Something tells me, the second sentence is nothing you want to hear when doing the first thing 😛
In America we just call it "Cream Soda" and it used to be popular in the past but some people still drink it now
At least this didn’t start with a spicy pillow, lol
Also, I wouldn’t call cream soda popular here, but it’s a thing… I like cream soda
"This is where things go horribly wrong."
And the audience let out a collective "Oh goody". 😁
i like how this chinese product is actually good quite suprising
not much spacing between the cell and the case (defeats the cell from having expanding design?) – sorry waking up an old thread 😉
Looks like you got yourself a pocket warmer. Good for cold weather nights . You just need to move it from one pocket to the other. It don’t think the manufacturers printed out any instructions so be careful charging up your iPhone.
I REALLY REALLY DISLIKE FLIR, WHY does your silly little "watermark" need to be on 500+USD devices? SERIOUSLY? HOW EGOTISTICAL do you have to be?
what a waste of paper 🙁 learn to use screenshots and video editing
Nouice
Pink and acceptable
Cream soda is in grocery stores in America but it is one of the least popular probably.
I have recently found a new pop (Michigan term, soda to the rest of the world): Dr. Pepper and cream soda. Please allow me to quote the ad: "A brand-new duet that is sweeter than any other. The beloved Dr Pepper paired with the richness of cream soda makes for perfect flavor harmony. Take a sip of the symphony of deliciousness."
If you can find it, try it! If you can't, let me know and I'll try to get you some.
Put a modest amount of charge in it while drinking heavily is my new favorite quote.
