Wireless charging is a cool bit of technology as it is, but for the first time, the US Federal Communications Commission has just certified a “power-at-a-distance” charger that makes the current technology look as old-fashioned as sticking in a cord looks now.
The device is called the WattUp Mid Field transmitter, and Energous, the startup responsible for making it, claims it lets you charge multiple devices at once from a distance of around three feet.
The intended device needs a special internal or external receiver for the WattUp transmitter to work, but apparently the receiver is small enough to fit into most phones, and it reportedly also works with waterproof devices.
Unfortunately, a distance of three feet probably means the phone still needs to sit in a fixed spot, so you shouldn’t get the impression that you can charge your phone in your pocket while strolling around the office.
Even so, Energous’ official announcement gives the example of “charging a fitness band even while wearing it,” which appears to mean it may work if the transmitter is beaming the waves at you while you’re on the treadmill.
Energous has also developed a version of the charger that works from 15 feet away, but for now only the three-foot version has been approved by the FCC.
