JAYLENE Portable Power Bank (50,000mAh, 22.5W)

I ripped mine open for science. For how heavy this thing was, there was no fake weight. It has 3 chonky 10000mAh 3.7v pouches in there which will realistically put it a little under 30000mAh total (haven’t got to test that yet, I can’t find my dummy load). But the downside is the cells are all connected parallel with no battery balancing or protection that I can see. Which means it will work great until it doesn’t; Then it has a chance of turning into a smoke grenade/fire bomb.

I probably won’t carry this in my backpack as originally intended, but if the cells test out anywhere near their rated capacity, they are worth $16 for other projects.

There’s no protection circuitry under the tape, I took it off after taking the picture.

Control chip if you want to go Big Clive on it.
