Hello, im new to this forum and i hope to be part of this community share and help.
ok i have a couple of power banks that i really like to fix, maybe understand and improve design is for study ,im and IT tech with some very basic electronic but with hungry for knowlegde and i hope to find the answers that i look for in here, sorry for bad english i im self learner.
The subjet:
So this is a one cell energy bank i bought some time ago i take it aparte and teste it,measure voltages and change lithium cell. know it doest light up and charge the battery just to 2v, i also remove the leds but i think its part of the circuit i cant see the ic number i have search over the internet and it seems to be something similar to the F6316,i also see that it has very few components that sorrounds it and maybe can be improve.
I will post some images and put some data you ask i have basic equipment to measure and soder and components to change i will like to troubleshoot it in case i need to fix it again and know more about the quality and the commons faults.
