The Blue Freedom is the world’s smallest portable hydroelectric plant, tipping in at a mere 400 grams. The little hydroelectric turbine supplies 1A and 2A USB ports, ideal for recharging most of today’s devices. Drop the little turbine into the creek by your camp site as you set up camp and in 1 hour, it generates a modest 10hr battery life (5000mAh) with 5w of power. A handy, green and self sufficient way of getting electricity on the go.
