Hand-Crank Flashlight Doesn’t Need Batteries

stashed away in every room of my house.
The beauty of it is, there are no batteries needed! You just Shake it to light it.
A 30-second shaking generates power for five minutes of bright illumination. OK, so it’s wise to shake them up BEFORE you need them.
They’re shockproof, rubber-guarded, waterproof, floatable and ideal for every vehicle or home emergency kit. The LED bulb never needs replacing and there are no batteries to worry about ever!
