Wireless Power
The Powermat Portable is intended for travelers who are tired of lugging around a collection of chargers for mobile devices. Place any device on the mat, and it uses induction to deliver a wireless charge; the power flows to small receivers that can be fitted to most handheld gadgets. The Powermat is powered by an AC adapter, but a built-in lithium-ion battery allows charging when you can’t find a wall socket.
