Why My Power Bank Cannot Charge. Here is how I solved it. Such power cables do not support fast charging technology as the power bank requires.
We have seven main reasons why the solar power bank does not charge. Also The problem can be a board or battery that c. Unplug the Power Bank from the Charger.
If your charger does not charge you should first check its connections.
Keep in mind that the first four here account for 98 of all problems with the rest. If the phone is idle and goes into sleep mode that seems to be the problem. It seems another explanation is polarity mismatch. Also the USB socket on the power bank should not be loose.
