A:AnswerI use it with my iPhone 11 and it charges fine, I’m sure the 12 pro would work on it as well. I charge my series 6 watch on it and it charges perfectly. Had to modify mine a bit due to my choice of watch case but I’ve had no issues with it at all.
A:AnswerYes. Works with all apple watches (you must provide your own magnetic charging cord for the watch portion), and any phone that works with Qi wireless charging (IPhone 12 Pro Max falls into this category)
