After showcasing the prototype of the first-gen Apple Watch in early 2020, prototype-device collector Giulio Zompetti has now got his hands on a rare engineering model of Apple’s canceled AirPower wireless charging mat. The Italian man recently shared some interesting tidbits about the wireless charging device that Apple could not deliver to its customers.

Speaking about the overheating issue for which Apple canceled the AirPower project altogether, Zompetti says that he has not been able to reproduce the said issue on his model. However, he adds that he “still can’t say it isn’t there.”
