When we say our newest astro flashlight is "self powered" we mean it is powered by your own bad self! The RedBeam SP has a small hand crank that when wound charges an internal rechargeable battery. There's no need for any other batteries ever! Just 1 minute of winding cranks out up to 15 minutes of red LED light! Red light preserves your dark-adapted night vision while you read star charts or check your equipment. Choose from two brightness settings which illuminate three or all five red LEDs. The RedBeam SP can also be charged from a USB port (USB charge cable included). It can even power a cell phone in an emergency (five popular cell phone adapters are included). Get the astronomy flashlight that never needs additional batteries!
