Apple announced its wireless charging mat AirPower in full glory in 2017. However, the device couldn't see the daylight due to technical limitations. Now, a video shared by Apple Demo on X (formerly Twitter) shows a prototype AirPower charging mat powering an Apple Watch. Apple Demo noted that AirPower gets quite warm as it manages to charge the Apple Watch, "given wireless chargers today generally can't charge Apple Watches." For reference, the Apple Watch relies on a magnetic puck charger to power itself wirelessly.

It's amazing that Apple Watch charging works, given wireless chargers today generally can't charge Apple Watches. However, the Apple Watch on AirPower gets quite warm. #appleinternal pic.twitter.com/GfywG3KZS9
