Self-Powered (Shake) Emergency Flashlight

Battery-operated flashlights can run-down, dim and fail. This self-powered flashlight lets you power-up the voltage simply by shaking it... agitating a copper coil magnet that recharges the built-in capacitor again and again. 30 seconds of shaking generates 3-5 minutes of light. Durable, unsinkable water proof case with easy-grip contouring and power button.
