The box for Apple's new AirPods might be a hint that the long-promised AirPower might finally be released after over a year of delay

The AirPower, Apple's long-promised wireless charging pad, has resurfaced on packaging for Apple's updated AirPods.

The AirPower was first unveiled in September 2017 alongside the iPhone 8 and iPhone X, but it was delayed amid reports that it had faced technical challenges in development. 

People who received the new AirPods this week quickly noticed that the AirPower mat is pictured on the packaging and mentioned by name on the box, dropping a hint that it could finally be on its way. The biggest new feature in the new AirPods is a wireless charging case, so it would make sense for Apple to launch its own wireless charger in a similar timeframe.

Based on previous announcements from Apple, AirPower will be able to charge up to three Apple devices wirelessly by placing them on the surface of the mat.

The iPhone X, Xs, Xs Max, Xr, 8, and 8 Plus models all suport wireless charging using devices made by third parties including Mophie and Belkin, but Apple's AirPower will have some secret sauce — the iPhone will be able to display on its screen the charging level of any Apple Watch or AirPods also on the mat. 

Apple is selling the new AirPods with the wireless charging case for $199; standalone wireless cases for use with existing AirPods are available for $79. There's still no official release date for the AirPower, but we've reached out to Apple for comment.
