We’ve been hearing about using fuel cells as batteries since fuel cells existed. So far, nothing too interesting has come out. But if you’re interested in getting in on the tech early, check out the Powertrekk. The Powertrekk is a fuel cell and rechargeable battery in one. Similar to those portable battery chargers, the Powertrekk can charge your devices over USB from energy stored either in the fuel cell or the battery. The battery also acts a buffer between the fuel cell and your device.
Check out the video to see how it works. It looks a bit messy, but hopefully they water, battery and hydrogen don’t turn into something explosive. Right now, we aren’t seeing a price or release date.
