Harvesting USB power from nature for the world! Our Personal Power Products are recharged by flowing water, wind, bikes, muscle power, donkey carts, sun, fire, or pretty much any source of energy to generate power for battery charging, LED lights, sensors, cameras and wireless transmitters. Over 1 billion people living off grid now need USB power for phones and LED lights and now they can get it from any natural energy source. Please follow us on LinkedIn, Facebook (@HydroBee), Instagram (@HydroBee), and Twitter (@hydrobeeUSB) so you can stay updated on all of the changes and news about HydroBee!
