HI Asish,

Probably the mainboard have problem.There is not much thing you can do because there was no info about this type of circuit board. What you can do is to reflow the ICs and do some cleaning using IPA. If the memory ICs is corrupted there is no way to find one unless you can find the exact same model to copy it out.

Hi Ashish,

How long you have been using this power bank? Have you opened it up and check the battery voltage?

Hi Clinton,

How long has you been using the power bank? It could be the battery can't sustain the current draw.

HI Tonn,

Make sure the batteries are good first before checking on the circuit board. After few years in service the batteries usually will go bad first.

Hi Okpala,

Check to see if the battery voltage is depleted or not. if it is too low then it would be difficult to charge it. You may use an external charger to charge it or direct replace with new batteries.
