Camping or hiking presents a problem for the technophile. Unless you bring a backpack full of batteries and portable chargers, you're not gonna be able to use any of your portable gadgets for too long. Enter the PowerTrekk.

Using fuel cell technology, the PowerTrekk is able to cleanly convert hydrogen into electricity. All you have to do is fill the included PowerPukk with a tablespoon of water, place it back into the device, connect your gadget via USB, and wait  for it to charge. The only bi-product from the entire process is a little water vapor. If you're planning go to get off the map for a little while, or don't want to get stranded next time there's a city-wide power outage, cop one now at powertrekk.com.
