The innovative types at eZelleron have come up with this fuel cell power generator that runs on standard lighter gas, camping gas or butane, needing only a few seconds to refuel. Just plug in your device and it’s like you’ve tapped into a wall outlet. Turning gas into electricity, Kraftwerk promises to charge up an iPhone up to 11 times on one tank of fuel, and the makers it’s completely safe and comes with a two-year warranty. [Purchase]
