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
