I guess this has to be the gadget of the year. No matter how much I surf for new gizmos this one gets the cake, I mean we have heard about wireless charging but this one beats them all. The device I am talking about is an RCA charger from Airnergy that harvests electricity form Wi-Fi signals to charge batteries. Now that is certainly cool, but wait there is more to it.
It was unveiled at CES 2010, and charged a BlackBerry from 30% to 100 % in about 90 minutes. All it needs is a Wi-Fi router or AP in the vicinity, if there are more than one off course the performance will increase. It also has a battery inside it so one can charge it and carry anywhere. It also has a USB for attaching to various mobile devices. Coming in summer it will cost around $40.
