Contactless Charging Devices are Coming

Charging your mobile device wirelessly is certainly less of a hassle than plugging it in, but still requires the device be in physical contact with its station to actually work. That's about to change now that the Federal Communications Commission has approved the first wireless charger that works from up to three feet away. San Jose-based startup, Energous, announced on Tuesday that it has received the first such FCC certification for power-at-a-distance wireless charging with its WattUp Mid Field transmitter. The transmitter converts electricity into radio frequencies, then beams the energy to nearby devices outfitted with a corresponding receiver. This differs from the resonant induction method that the Pi wireless charging system relies upon and offers a greater range than the Belkin and Mophie chargers that require physical contact with the device.
