Hi, I have (had) a broken Power Bank unit that apparently had 50,000mAh capacity - pretty sure it was broken because the USB sockets were damaged physically. I cracked it open and it has 8 18650 batteries inside which I have been able to remove (and measured the voltage - they are currently at 3.6V)…
