In 2017, Apple announced the Qi-compatible AirPower Mat, a device that would charge multiple devices at once simply by placing them on the mat.

That product has been seriously delayed due to reported interference and overheating issues, with a whole year going by without hearing much about the availability of the product. In fact, Apple’s total silence on the matter led some to believe it may have been canceled altogether.
