Motorola’s upcoming Moto 360 smartwatch has been largely shrouded in mystery. While we’ve seen developer examples of the Android Wear operating system that powers the Moto 360, most of the hardware details have simply been teased since its original announcement back in March. Google’s I/O conference will likely provide more information on the Moto 360 and Android Wear tomorrow, but the FCC has revealed ahead of time that Motorola’s smartwatch will support wireless charging.

In a test filing, a "Motorola Wireless Charger" is listed as a circular stand "intended for use with the Moto 360 wrist-worn device." The charger uses the Wireless Power Consortium (WPC) protocol, commonly known as Qi, which indicates the Moto 360 will sit on top of the device to charge wirelessly. It’s possible that any Qi-compatible charger will work with the Moto 360, but that will depend on exactly how Motorola has implemented its wireless charging support. Motorola is planning to release its Moto 360 smartwatch this summer, so more hardware details and pricing should be available in the coming weeks.
