Charge Your Phone with Hydropower

WaterLily is a portable river turbine loved by paddlers, campers, and off-gridders around the world. It charges phones, speakers, cameras, battery banks, and even 12V devices, by generating power from rivers and streams.

Water, wind, and you.
WaterLily is the only portable power solution with three sources of power.

Rivers, streams, creeks, and brooks. If water is flowing and WaterLily’s blades are spinning, you’ve got power.

WaterLily’s efficient blade design works in wind, too.

And you!
Use WaterLily’s hand crank to generate power on-demand. Great in emergency situations.




Plug into nature.

Charge your devices anytime, day and night, with consistent, reliable river power.

At home convenience.
Setup camp near a river and use WaterLily like a power outlet.

Plug in and enjoy your day.
Spend your day exploring while WaterLily charges your devices.

Charge overnight, just like home.
Plug in your devices before bed and wake up to full batteries in the morning.


Stay safe, stay connected.

When you’re 100 miles from an electrical outlet, reliable power is a matter of safety.

Any weather, any time of day.
When solar isn’t an option – rain, fog, shade, treecover, overnight – WaterLily can keep your gear charged.

On-demand and in emergencies.
No water? No wind? No problem. WateryLily’s hand crank can provide emergency power when you need it most.

Built by experts.
WaterLily’s patented HydroElectric Charge System comes from 7 years of subsea research in the rugged North Atlantic Ocean. It’s proven.

Not just for paddlers and campers.

Got an RV? Sailboat? Cabin? Living the vanlife? From bushcraft to packrafting, WaterLily is for you, too.

Redundancy for your cabin, RV, or sailboat.
Batteries die, the sun sets, and generator fuel runs out. WaterLily gives you more power and peace of mind.

Add it to your emergency supply kit.
When hurricanes and floods take down power lines, WaterLily can provide a consistent, 24-hour source of power in times of emergency.

Power for your devices.
Charge USB and 12V devices, including cell phones, GoPros, LED lights, small and large battery banks, bluetooth speakers, GPS, lead acid batteries, and more.





Charge devices as fast as you do at home.

In an average river, WaterLily charges most small electronics as fast as your wall outlet at home.

24 Hours of Power
The sun doesn’t always shine, but rivers flow 24/7, so WaterLily can generate 8x more power in one day than 14W solar panels.

Power Without Maintenance
Solar panels require re-positioning as the sun moves across the sky, but WaterLily can run for days without maintenance.

Spectacular Value
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. A 100W panel? 300!

Power Overnight
Instead of fussing with your solar panel during the day, setup WaterLily for overnight charging and wake up to full batteries in the morning.


Unrivaled Design and Durability.

WaterLily’s patented technology was developed from subsea power harvesting research conducted over the past 10 years in the rugged North Atlantic Ocean.





There is no single right way to set up a WaterLily – there is also no wrong way, as long as you are safely capturing fast moving water or wind. You have to be creative and think about the best way to capture the most water or wind energy in your current environment, keeping in mind that rivers can be dangerous and your personal safety should be the most important factor.

Across the Flow

This configuration works well in rivers where you have anchor points on both sides.


In-line with Flow

This configuration works well in rivers, and could also be used to tow the unit behind a canoe or kayak.


X Configuration

This is a very stable configuration, but also the most work to set up. It is a good option for wind, where it can be installed between two trees.



In this configuration you can hang the WaterLily from a single point, using a weight (knapsack, rock, etc.) to keep it from swinging. You can then use the charging cable to keep it oriented in the direction of the wind.


Anchor the Output Port

Any time you use the WaterLily around water, you should tie off the Output Port to be sure that it (and your connected device) does not get pulled into the water.



Be careful when choosing your anchor points, and in the knots you use, especially around water. A failed knot or anchor point could mean your device is pulled into the water. We have included a diagram of secure knots as a suggestion.

After using the WaterLily in salt water, rinse it off in fresh water to help prevent salt deposits and corrosion.

If anything gets stuck inside the WaterLily (grass, string, etc.) it can be easily disassembled to clean. Just remove the four screws to remove the cover, and unscrew the nose cone to remove the rotor.

Some devices do not handle direct charging from the WaterLily when the water or wind speed is low. This will be apparent because the device will alternate between charging and not charging as the turbine speed changes. One solution to take care of this issue is to:

-Charge a power bank with the WaterLily, and then charge your device from that.

 Important Safety Information

  • Do not put your hand inside the device while the blades are spinning. Injury may occur.
  • Do not cut the cable, or continue to use the device if the cable becomes damaged.
  • Do not attempt to modify the device in any way.




The Double Bowline (pictured) is a great choice for putting a fixed-size loop in the end of a rope. It is a secure knot that will not come undone on its own, but is also easy to untie if needed.

There are many other options for secure knots for different purposes.
