So my power bank decided to stop working, and as I am useless at this stuff, I thought one of you guys could help me fix it. The LEDs don't light up and it doesn't seem to charge itself or anything else. If anymore pictures are required, please let me know in the replies. Any help would be greatly appreciated.

 

Have you measured the battery voltage?

 

Have you measured the battery voltage?

I haven't measured it but it supposedly has a 5v-2a input and a 3.5a output
How would one measure voltage?

 

By using a voltmeter or DVM.

 

If one or more of the cells has died the protection circuit on the PCB will prevent the battery being charged or further discharged. This is a safety feature to avoid fire or explosion. Replace the power bank.

It's a few weeks old

Is there any way of checking if this has happened

I've had 2 of them power banks die both was simple as heck to find problem.
start by looking ad the battery mine had the weld break on both they looked to have tin spotwelded to them to tie them together and then soldered to the main board both welds had popped off.

 

In my power bank while discharging the D6 led is always on but not charging my phone.Also the power bank is not charging. What might be the problem ?.help me to find solution.

 

If the cells are good, buy an "empty" power bank from your favourite overseas electronic bazaar and install them. Or if you have a working power bank that has weak cells, use the good ones to upgrade it.
