AirPower is Apple's wireless charging pad; an oval-shaped surface large enough to hold your iPhone X, 8, or 8 Plus, or Apple Watch and charge them. The whole setup works without cables and can charge up to three devices at once.
AirPower will also work with AirPod headphones, provided you buy Apple's new battery case for the headphones with wireless charging capabilities. It's likely the AirPower units and the charging-enabled AirPods case will launch at the same time, though there's no mention of that in MacOtakara's report.
Apple is separately expected to launch a second-generation pair of AirPods.
