Xpal Power (owners of Energizer and PowerSkin) has leveraged its battery-tech know-how into the SpareOne, a cellphone that can maintain its charge for up to 15 years on just a single AA battery. It's designed to be used for sponsorship, hotel use and (most importantly) emergencies, to throw into your trunk and forget about until you need to contact roadside assistance. Now at CES we've had a chance to get our mitts on the device to see what it's like in the flesh plastic. If you're just a little bit curious, why not join us for a short trip?
