How It Works & Usage Tips

The flashlight contains an aluminum power cell and internal salt water tank; when you pour in water and dissolve salt to the proper concentration, a chemical reaction generates electricity to drive the 1 W LED. Users can simply refill with fresh salt water when light output weakens, repeating this process until the aluminum electrode’s service life is reached. For best performance, empty the liquid and rinse the tank with clean water if the product will not be used for several hours, and avoid placing the exhaust port face‑down to reduce the risk of leakage.
