18 Attention Grabbers From CES Opening Night

Powermat USA made a splash at CES last year with an easy-to-use product that charges mobile devices when they're placed on top of it. While the technology was interesting, it wasn't quite as easy to use as people hoped because it didn't work with all phones and required add-on devices.

Powermat has since honed its approach, and at CES 2010 is showing off its new PowerPack battery, which replaces conventional cell phone batteries to allow them to charge when used with the Powermat. That might sound a bit convoluted, but Powermat's booth was mobbed for the entire three-hour CES opening night event, so there's obviously strong industry interest in this technology.
