Portable Generator

Estream is a new portable hydropower device that could convert running water into electricity that could be used to power smartphones and other USB devices. Estream is about the size of a water bottle and weighs at least 2 lbs.  Once dipped into running water, the turbine rotates and generates electricity, which will be stored in Estream’s built-in 6,400mAh lithium-ion battery that takes about 4.5 hours to charge.
