Hand-Cranked LED Spotlight

99095_ts.JPGWell, we've covered hand-powered LED flashlights previously. But what we've got here is a hand-cranked spotlight with no less than 16 LEDs. The spotlight has a 6V battery than can be recharged in three ways: through a regular 120V socket, a 12V DC cigarette-style socket, or the crank generator. One minute of cranking will provide 3 minutes of light. :: Amazon and Sportsman Guide
