A:AnswerYes this charger works with my GFs iPhone 11. The magnetic feature is unique to iPhone 12 natively. You can buy third party magnet rings to adhere to any other phone with Qi wireless charging capability to duplicate the physical behavior but, not the 15w charge rate. I think it charges at 5w, 10w and 15w increments.
A:AnswerTechnically, it should in an emergency without other charging options. In any other case it would be a poor choice. It is really only designed to work well with MagSafe enabled iPhone12, it is even a bad choice for other iPhones at this time.
A:AnswerNo, you will have to take the wallet off each time. The magnet on the charger can mess with your cards in the wallet and end up clearing them or something!
A:AnswerOnly as a standard wireless charger and will not charge your phone fast. Someday there will be third party cases that will have magnets allowing this to work with other models but for now and by itself, it will not magnetically charge.
