I have one like that, and it doesn't last long due to the heat generated by the circuit board getting too hot if used for too long with fast charging on
I guess it's either overheating or a battery that doesn't have a BMS, sometimes when the percentage is below 50% the power bank suddenly turns off and shows 0%, I don't know what the problem is
I have this powerbank. how to calibrate the percentage? the battery % is dropping very quickly from 100% to 1% in 20 minutes. when it reaches 1% it will be steady for a long time 10-12hrs straight usage before it reaches 0% pls help how to calibrate
I ordered that from China. The problem is seller did not give me the right side outer shell. the one with lightning port , type c and USB hole. There is no way to give it back. is there any way to make the shell? without it i can not complete the power bank
It's been more than a month since I bought the same power bank circuit case. But I can't get good quality 18650 model lithium battery in my local market so I can't even make power bank.
use old laptop battery and you can get best quality cell from it. in a 4 or 6 cell battery you will get 2 to 3 cell fully good. you can get old laptop battery for free or few bucks from repair shop

That causes the battery to overheat and damage it, I have replaced it many times but the result is the same
But i never get that issue 🤔
The circuit gets hot but not that much to melt plastic

Maybe your circuit is faulty?
Or defected ic?
The interesting part is it can output 5V 4.5A , where to buy?
AliExpress, eBay, daraz , and other platforms

I think it's factory fault cannot be repaired
it says on the sellers website, you are supposed to fully charge and drain it a few times it will calibrate the percentage
That looks amazing
Thanks
I have this, home made too. but is this just 2 out 3 input ???
Maybe 3 i don't know about type c Port , it can be PD mode also

You can ask for a return or refund from the platform you ordered from
i was away from home when the deliver was done, now refund time is over. is there anyone who sell spare parts online??@@Electronic_For_You
