WaterLily charges your devices using River Power. Quick and easy setup and fast charging times make WaterLily a great choice for all of your USB charging needs including; cell phones, USB battery banks, camp lights, speakers, cameras, and more. WaterLily is a portable turbine loved by campers, paddlers, filmmakers, and off-gridders around the world. It charges phones, speakers, cameras, battery banks, and even 12V devices, by generating power from rivers and streams. The sun doesnt always shine but rivers flow 24/7, so WaterLily can generate 8x more power in one day than 14w solar panels. Solar panels require re-positioning as the sun moves across the sky, but WaterLily can run for days without maintenance. WaterLily can generate up to 360 Watt hours of power in a day. A 14W solar panel will generate 42 Watt hours on a good day. Instead of fussing with your solar panel during the day, set up WaterLily for overnight charing and wake up to full batteries in the morning.
