My Power Bank Doesn T Charge My Phone. When I put the power bank for charging only one light blinks for sometime and then all four lights start blinking together but the power bank doesnt charge. Naturally power banks with large battery sizes are going to take longer to charge.

Shortcut due to high humidity or a defective cable and appear to be defective. Charge the power bank via a wall socket not via a laptop USB. Power banks ensure that your devices wont run out of charge.

We mean thats not very convenient since its the same way you charge your phone anyway. PowerBanks sometimes just switch off for safety reasons eg.
