My powerbank platinet 9000mAh after 5 minutes of standby goes asleep and wakes up when I plug in charger or any device.
When I connect raspberry pi, usb camera, wifi adapter or pendrive my powerbank wakes up. Problem is with my samsung galaxy s5. Nothing happens when plug my smartphone - powerbank remains in sleeping mode. Firstly I have to connect any other device - then it's wakes up for 5 minutes and I can plug in my samsung and charge.
Where is the problem? There are no buttons on powerbank.
