Check out the Waterlilly Turbine, a generator that can charge your devices with either wind or water. Aimed at campers, this device can be submerged in flowing water or suspended in the wind, turning that energy into stored electrical energy. You can charge an iPhone 7 in 2-4 hours, or you could charge a portable charger over a longer period of time. Like, say, while you’re out hiking, fishing, or otherwise getting your nature on. It comes with its own portable 2,600mAh power bank, or you can charge a separate device. It’s 7-inches square, regulates its power output, and is pretty cool. Waterlilly Turbine retails for $159.99, and it’s $159.00 at Amazon.
