Hi.
Just curious.
After fully charging your device with a PowerBank (external battery), Is there any issues having your smartphone running using the PB batteries until drained, then switch to the device battery?
More specifically, should a PowerBank battery be used as a backup charger and/or be used only when there are not electrical outlets?
