Charging a mobile device wirelessly has finally become a thing in 2017. However, when the method is certainly convenient than plugging in, it still requires the device be in physical contact with its station. That’s about to change, now.

The Federal Communications Commission (FCC) has approved the industry’s first wireless over-the-air, power-at-a-distance charger that can work from up to three feet away.

Energous, a San Jose-based startup, announced on Tuesday that it has received FCC certification for power-at-a-distance wireless charging with its WattUp Mid Field transmitter.

The technology used in the WattUp transmitter converts electricity into radio frequencies, then transmits those to nearby devices with a corresponding receiver. The method differs from the resonant induction method which is used in Pi wireless charging system.

As it’s explained in the video, WattUp can charge multiple devices simultaneously and works on any device, from a phone and tablet to a keyboard and earbud, as long as they’re outfitted with the right receiver.

Energous, though, does not have any retail-ready devices available, they plan to show off the latest technology at CES 2018, which starts on January 9th in Las Vegas.
