Amazon カスタマー 5 The adapter has USB-A and USB-C ports, but both cannot be used at the same time. On the contrary the phone battery starts losing its power!When only one USB-C port is used then the phone can be charged no problem.This disfunction is probably caused by the wrong inner design of the adapter.Even after getting a replacement, the situation hasn’t changed. I can’t charge my iPhone and iwatch at the same time.
