Can an Apple 20 W charger be used to charge this device? Also, are the LED lights supposed to come on when charging?
May be it can be done, though very slow.
Give it a try.
There is a half circle of led on the pb “increasing” when charging
All blue when charging is done!
Probably. Don’t look at Watts, look at protocols and volts.
Probably 20W is 9V 2.2A, the Powercore wants 9V and at least 1.5A.
Yes lights come on when charging, if not then charging not working
It should work but I wouldn’t expect faster charging times
