A:AnswerMy daughter has an 11 Pro and it works. When I've set my 11 on there, I have to move it around a bit for it to charge. I'm sure the 12Pro should work. If you can't find the right spot, there more then likely is something wrong with the charger.
A:AnswerI bought this Mophie 3-in-1 charger for my wife to eliminate having to have multiple chargers for her devices (iPhone, Earpods, Apple Watch). She's found that the phone charging section of the Mophie 3-in-1 is VERY particular about how you place the phone. Even when placed initially in an acceptable orientation (phone beep+ solid white charging light on the Mophie), the phone will sometimes give an audible "beep" in the night, and the white LED charging light on the Mophie will be blinking. Given this experience, I would recommend avoiding this charger if you plan to keep your pop-socket.
A:Answerthere is an indention that exactly fits air pods pro so I expect a larger, flat object would not rest on the charging spot. I also expect that an ipad would be too large for the charging pad.
