A Columbia University startup wants to take wireless charging mainstream

Wireless electricity of the sort envisioned by Nikola Tesla seems to be the charging ideal which the world is striving toward. Who wouldn’t, after all, love to be able to plop down their smartphone without having to plug it into a wall socket, set it on a charging pad, or dig for the appropriate cable? Given the acute lack of such chargers on the market, you would be forgiven for dismissing true wireless charging as a pipe dream. But thanks to bright minds at Columbia University, the dream is closer to reality than you think.

Yank Technologies, a startup headquartered in Columbia University’s startup lab, developed a router-like wireless charger, the MotherBox, capable of delivering power at a distance to multiple devices simultaneously. It works without wires, a charging pad, or a dock, and doesn’t require a physical connection between the charger and smartphone. Charging takes place entirely over the air.

The MotherBox is simple to use. Once a receiver is attached to an Android device, iPhone, or another compatible smartphone, charging begins. The closer the devices are to the charging pad, the faster they charge. And from there, users can move around the MotherBox at will — the transmitter automatically compensates for obstructions. A companion smartphone app lets users customize the rate of charging and serves push notifications when connected devices begin to run low on battery.

The MotherBox and smaller MotherBox, the MotherBox mini, have ranges of up to 20 feet and 10 feet. The MotherBox mini must be connected to an outlet, while the MotherBox Mini packs a rechargeable battery that can be used on the go. Both ship with a USB cable and receiver.
