I’m going to let everyone here on a little secret, apple AirPower mat worked just fine with iPhone or AirPods, you could place them anywhere and anyhow, and it worked just fine, the problem was with the watch, when charging it was setting off secondary coils, next to the device, which in fact made the mat heat up more then usual, and after extensive tests these stoped working in a proper way. However, the project is not scraped, as a matter of fact, there are extensive tastings on a new way of achieving this, plus 2021 most likely will bring in long range wireless charging, be patient.
