At its iPhone 8 and iPhone X event in September, Apple announced plans to release a wireless charging mat called the AirPower. February rumors suggested the device would make its debut the following month, but that never happened.

Now, word has it we're still months away from AirPower's launch. Bloomberg reports that AirPower is taking longer than expected to arrive "due to a series of technical hurdles," and that Apple now aims to release the device "before or in September."

Apple did not immediately respond to PCMag's request for comment.

Accessory makers like Mophie and Belkin already make wireless iPhone chargers, but AirPower's killer feature is supposedly its ability to charge an iPhone, Apple Watch, and AirPods charging case all at the same time. The only problem: Apple hasn't yet revealed when AirPower will be available or for how much.

"An executive at an Apple partner that manufactures third-party wireless chargers for iPhones, who asked not to be identified, said that the multi-device charging mechanism is challenging to build because it likely requires different sized charging components for the three types of devices, which would all overlap across the mat," Bloomberg says.

This is just the latest in a series of recent Apple product delays, including AirPods and HomePod. Originally slated for an October 2016 release, AirPods didn't start shipping until December of that year, and were initially only available in limited quantities. Apple first unveiled HomePod in June 2017, meanwhile, and said it planned to start selling it that December in time for the holidays. But the Siri-backed smart speaker's launch was delayed until this past February.
