Tow this portable hydroelectric plant behind your boat for unlimited power in the woods.

While most of us like to disconnect from the world when we’re off camping or hunting, there’s no denying that these days you have to stay connected more often than not. But without a reliable source of power out in the wilderness, things like your phone won’t stay juiced for long. That’s a problem the inventors of the eStream portable power supply think they have the solution to. Using a small turbine to generate charge in a sealed, watertight battery, the eStream can be towed behind a boat or anchored into a moving stream. After the battery has been charged, it can be used as a USB charger for any gadgets you may have, or as a lantern with multiple brightness modes.
