iPad charging issue only with 18w adapter
So I have a very weird issue. All the sudden my iPad Pro started not charging it just charges a bit and stops on and off the icon just flickers. But in testing the charger I switched cables and bricks. It will charge fine with my MacBook charger, directly from my MacBook or from a usb a to c cable plugged into a hub. With an Apple or non Apple cable. However the issue occurs only when plugged into the Apple 18w brick that is included I have tried 3 different ones and all do it. Tried 3 cables and all do it. Try those same cables on the MacBook or the MacBook brick and they work just fine. What would cause only an 18w brick not to work?
Is this a good question?
