Apple has officially canceled AirPower. I cannot find any evidence of another time Apple has announced a product and then canceled it. Here is the timeline;
September 12, 2017 - Apple Announces Airpower and says it will be available in 2018.
September 12, 2018 – Apple Removes almost all mention of AirPower from its website.
September 20, 2018 – iPhone XS packaging mentioned AirPower as a way to charge.
January 1, 2019 – Apple officially misses the deadline they gave to ship AirPower. They provide no statement regarding delay.
March 25, 2019 – New AirPods ship with an image of AirPower on the back packaging.
March 29, 2019 – Apple officially cancels AirPower.
AirPower was the perfect solution. The ability to charge an iPhone, Apple Watch, and AirPods all at the same time on a single mat without having to precisely place them in a specific spot was something that has never been done. Sadly, that still remains true.
