Power bank not working. What to do?

Question

Electronics

Good day, gentlemen. In general, a friend gave me her idle powerbank. And it is not working because it does not show the charging indication and does not charge the connected devices. When the bank is connected to charging, the first of the 4 charging indications turns on and goes out after a moment. When you connect the device, it starts charging for literally half a second, after which it no longer charges. What could be the cause of the problem?

Answer 1

dead driver. you open - you change the driver - you use. but it's long and tedious.
it’s easier to open it, check if the banks are alive, order an empty power bank from China and put live banks into it.
if on lipoic batteries, then look in China for a driver's scarf, suitable dimensions and replace it.
