A Sherpa 50 battery by Goal Zero is displayed during "CES Unveiled," a media preview event, at the 2012 International Consumer Electronics Show (CES) in Las Vegas, Nevada January 8, 2012. The battery can be recharged with solar panels or conventionally, allowing campers, hunters or adventurers to run mobile devices in the field. The CES trade show will feature razor-thin laptops, powerful new smartphones and fancy flat-screen TVs, but talk in the cavernous halls of the CES may focus on whether the show itself has a long-term future.
