When I use my iPhone for watching media, I like to have it connected to an external power bank to preserve its battery.
When tried the same thing with a USB-C iPad Pro, I found that when the external power-bank got exhausted the process went in to reverse and the iPad started charging the powerbank.
Is there any way to stop that happening?
