Does not work well. Power button doesn’t do anything. It charges my phone only half way and takes a really long time to charge.

Doesn't work as the brief instructions indicate. Switch that is supposed to turn charger on and off does nothing. LEDs do not function per instructions. Tried charging unit overnight - only 1 LED ever lit up. Returned to store for refund.
