myFC society will market a new loader. It works with a fuel loader and it's carriageable. It has a fuell loader and an usb port, it's light (don't know the weight), water-proof and ecofriendly since in order to have it to work, you just have to put in some water. The cell with use the hydrogen in the water to generate power. It's expected to become the new adventurer's fellow !
OK, there is an iPhone on the picture, but please, buy an Android !
