Apple is all for wireless accessories and one particularly interesting product it announced back in September 2017 was AirPower. AirPower was touted as a wireless charging mat that will simultaneously top up the iPhone, AirPods, and The Apple Watch. Although the company has a good track record when it comes to following through on announcements, it missed the alleged 2018 launch date of AirPower and hasn’t really mentioned its plans for the future. Up until now, it was thought that AirPower has been shelved due to overheating problems, but a new product listing in Malaysia has reignited hopes that we might see Apple announce the accessory soon.

When Apple’s new Smart Battery Cases went live on its website, it contained a reference to the AirPower. The listing has since been pulled off, but the Malaysian Apple Store still mentions the accessory. The product description says that the new iPhone XS battery case is compatible with AirPower, raising speculations that Apple might announce wireless charging accessory soon.
