I bought this 20,000mAh (probably more like 8,000mAh) power bank on ebay from a UK seller for about £10 and then took it to bits. (Well there's a surprise.)
One moment please…

" and I love electronic shit from China " EPIC. What a guy 😁
Why all these milliamps?
Did they stop selling power banks on ebay? seems almost impossible to find cheap chinese ones now apart from kits that don't include the cells, obviously these are always questionable but considering power banks cost an absolute fortune at local stores (since we don't have something like poundland) it would be nice to get some cheap cells even if their capacities aren't too high. I'm guessing their packaging was always a bit questionable for batteries like this so maybe shipping companies figured out how to stop them?
FIRST RULE OF CHINESE products and battery packs I have found very consistently that they add one more '0' to the pack so this is and I will bet that it measures less than 2000mAh , every battery i bought was the same as removing one zero, the 9800mAh turned out to be 980mAh
I'd be curious to see the inside of a Vinsic 20000mah.
I've loved mine – no complaints whatsoever, but I'd still be interested.
First thing is to examine that cell in the pink box for signs of spot welding on the terminals …. this will show it's been recycled from used laptop battery …. all trustfire , ultrafire , etc are recycled used cells , which have two end caps added to hide welded marks on terminals … the sellers re slieve and sell any cells which 'hold charge' … could have 500mAhrs or less , dont expect new cells in power banks.
The removable cell power banks are sold all over ebay for cheap and usually don't have any protection at all, they look EXACTLY like the Dollar general one I bought 2 years ago and used for 5 minutes before it caught on fire in my classroom, immediately plugged it in to my phone to get it up from 7 to whatever the charger could so I could make it to the end of school and get home, fucking waste of $7, told the store about it and they immediately stopped selling them, the lady even grabbed the manager right there (we go there a lot since 2013) and they went around the store and pulled them off the shelf
You shouldve stayed with this type of setup for videos
I'd love to see what is inside the zero lemon 8500mAh s7 edge phone case battery
i had one of those 6 cell banks and it only lasted an hour at 1amp load ?
get 6 3000mah lg hg2 cells then it will be true 18ah 18,000mah
