" LAS VEGAS--Powermat, makers of the inductive charging mat that won one of Popular Mechanics&amp;#039; Editor&amp;#039;s Choice Awards last year, is expanding its technology significantly for CES 2010. In addition to a variety of new cases, Powermat has also introduced two portable mats with integrated batteries that should come out in the second half of this year (a single device mat should cost around $60; a two device mat should retail for around $100). The batteries can hold enough juice for two full recharges per device you carry, allowing you to leave your cords at home.  On the device side, Powermat announced the Powerpack, a battery replacement pack that integrates the inductive technology, obviating the need for an external case. Twelve models of battery packs will be available at launch, supporting phones from HTC, RIM Blackberry, LG, Samsung, Nokia and Sony Ericsson (alas, no iPhone). The Powerpack will be available in the May/June timeframe and should cost between $30 and $40. "^^<http://www.w3.org/2001/XMLSchema#string>
