Meet the Blue Freedom: a portable gadget that lets you charge electronics outdoors using the power of flowing water. It fits in your backpack and can be used even in shallow water to store energy for your gadgets. 1 hour of Blue Freedom in a moving water supposedly generates enough energy to keep your smartphone working for 10 hours.
Blue Freedom has an integrated LED lamp and a 5000 mAh battery. It lets you keep your gadget charged outdoors. We can’t say how well it performs since we have not tested it. But you can find out more about it on Kickstarter.
