There are no pricing or availability details for the devices, but they're estimated to be released toward the end of this year. The most exciting news about this technology is that it's not limited to just device chargers. According to RCA, the AirPower can be embedded into any device. This means that soon, phones, MP3 players, and other battery-operated gadgets may be able to charge simply through a WiFi connection! Talk about an awesome (and electricity-saving) breakthrough.
