BioLite CampStove

At first glance this looks like your typical camp stove – then you spot the USB port. The BioLite CampStove charges up your USB devices while warming up your meal by converting the heat output from sticks, pines cones and the like into electricity. It would be particularly suited for charging a GPS or a dive computer, though we wouldn’t blame you if you just wanted some more Angry Birds time.

Be ready for a zombie apocalypse and get yours at Amazon or BioLiteStove – 129$.
