Flashlight that never needs batteries
The LED Forever Flashlight uses the Faraday Principle of Electromagnetic Energy that guarantees replacement parts will never be needed! The Forever Flashlight uses electromagnetic energy created by you to produce light on demand. Just shake the flashlight back and forth for 15-30 seconds, and enough electricity is generated to light its bright blue LED bulb for up to five minutes of continuous use.
