    I recently got the Samsung fast wireless charger. It lists input power as 5 volts, 2 amps. The USB to AC outlet adapter that comes with the Galaxy S7 edge is 5V/2A. I used that with the cable the phone came with to power the wireless charger. When I plug it into the wall with the wireless charger, the AC adapter itself starts to beep. The phone is not beeping, the charger is not beeping. The adapter is beeping. It's not a continuous beep but it is frequent at regular intervals, very high pitched very quiet. But it's noticeably there in a quiet room if your close to it. It is not present with lower amperage adapters. But I would like to use the fast charging feature without this annoying beep. Is it an adapter problem? A charger problem? Is it normal? Is the adapter engineered to warn you of something like this? Thanks in advance

    Maybe you could use your own samsung adapter or another new 5V 2A adapter to see if the same problem?
