Charging a sick power bank
Hi,
I have a power bank (branded Power Bank). It used to charge via a surface mount micro USB, but that is now surface unmounted. Ive opened the unit up (but not got my DMM on it yet. It consists of a small pcb (about 1cm2) and a cell / battery (A little bigger than an AA). Does the team think this could be recharged by connecting a regulated PSU to it? And if so, what voltage It might require? TIA Chris |

Big Clive has a lot of good videos on soldering on his YouTube channel including surface mounted stuff. Tim -- Please don't feed the trolls |

If you can get at the USB 5v input rails and give it 5V, the board should still charge it. I wouldn't charge the lithium cells directly without protection, since they could catch fire. If the power bank is sufficiently generic you might be able to find a replacement PCB: https://www.aliexpress.com/wholesale...power+bank+pcb or more likely transplant the cells into a new case: https://www.aliexpress.com/wholesale...power+bank+diy (harder if they're pouch cells than 18650s) Theo |
