It weighs in at 200 gram when full while measuring in at 3.94×2.95×1.18 inches. It features a single USB port that can be used for charging USB devices. The working is quite simplistic; a gas canister - butane cigarette lighter refill or the ones used at camping stoves - fill up the kraftwerk. The creator, eZelleron, claims that once the tank is full the device is capable of charging an iPhone up to 11 times. The gadget makes use of LED lights to relay when the gadget requires refilling.
