Rechargeable Battery-Free Shake Flashlight
Free of batteries, this light recharges when you shake it by sending an internal magnet back and forth through a coil of wires connected to a battery. This motion produces an electrical current in the wires which then charge the battery.
The Shake Light comes with a clear plastic casing that floats in water. The light can be visible for up to 1 mile when fully charged. This flashlight is meant to be used primarily for emergency lighting.
Charging capacity will depreciate over time, and it may be necessary to replace after years of use.
