Have a need for off-the-grid power? The PowerTrekk ($TBA) can supply it. This 2-in-1 portable battery pack and fuel cell can operate on its own as a simple battery, or can serve as a storage buffer for the fuel cell. Simply insert a fuel pack, add water, and the cell will spring to life, charging devices over USB without ever needing a wall charge. Great for camping, hiking, or getting through an extended power outage due to weather/zombie outbreak.
