A charger that absorbs Wi-Fi signals for energy

RCA Airnergy Charger Lets You Charge Devices With Wi-Fi

At CES 2010 in Las Vegas last week, RCA revealed what could be the world’s very first practical wireless charger — the RCA Airnergy charger.

The Airnergy charger connects to devices via a mini-USB port, and gets its energy from Wi-Fi signals, of all things. That means you can charge your devices whenever you’re in a hotspot, without ever having to plug into AC power. The Airnergy was tested on the CES floor, and it was able to charge a Blackberry from 30% to full-charge in an hour and a half.

RCA says the wireless charger will hit store shelves this summer at $40 a piece, and that the technology to harvest Wi-Fi will be released soon after.
