How does it work?

When a water-based liquid makes contact with the metal core, a controlled oxidation process begins. Inside the core, an integrated sponge absorbs the liquid and, once enough cells are activated, energy is generated almost immediately.

Since this flashlight is for emergency purposes, is a water capsule already included, making sure you only have to press the flashlight down to activate it.

The LED stays lit as long as the internal cells remain moist. Factors like ambient temperature and humidity can influence the duration. As the sponge gradually dries out, the light dims and eventually fades.

To reactivate it, simply add liquid to the handle or briefly submerge it— and the reaction starts again.
