Brunton’s Hydrogen Reactor Portable Power Pack is a two amp system that never requires a charge. (Come again?) That’s right, it never requires a charge. That’s because the self-contained unit mixes hydrogen from rechargeable cells with oxygen (from the air around you) to generate power. When a cell discharges, you can replace it with another to keep things running smoothly.
The whole device is just 5.3 inches long and weighs less than nine ounces. It allows you to recharge your iPhone up to six times via the on-board USB port before you ever need to replace or recharge. Plenty of juice for you and your friends next time you go on a camping trip.
