Eco-Friendly Salt Water Flashlight – Portable Emergency LED Torch for Camping And Blackouts

This palm-sized salt water flashlight turns a simple liquid into a dependable source of light and power. By adding a small amount of salt water or seawater through the top cap, the internal cell immediately begins generating electricity, driving the front 1 W LED without any batteries or external charging.

Compact and lightweight, it measures roughly 73 × 72 × 40 mm and weighs about 73 g, making it easy to carry in a pocket, backpack, glove box, or emergency kit. The body integrates a focused LED beam for torch use and a side USB port that can supply 5 V / 1 A output, ideal for powering LED light strings or small low‑power devices when other energy sources are unavailable.

The aluminum–saltwater power module contains no toxic heavy metals typically found in conventional batteries, and the used electrolyte can simply be poured out and the unit rinsed with clean water, offering a cleaner option for homes, schools, and remote communities. Each refill delivers around 15 Wh of energy, with a total designed capacity of approximately 105 Wh, and the product can remain in storage for up to about ten years before activation, making it an excellent choice for long‑term emergency preparedness. Whether you are camping, preparing for blackouts, or demonstrating green energy to students, this salt water flashlight provides a practical, sustainable, and engaging lighting solution.
