This hand-cranked flashlight provides 25-30 minutes of light, after one minute of charging. This is better than most hand-cranked flashlights, which need to be constantly wound or shook to keep them lit. The flashlight operates on an internal rechargeable lithium battery, which is recharged via the hand crank. It has a waterproof and shockproof shell. You can use either one or all three of the LEDs. The battery can be recharged 500 times (with proper use). The replacement batter is a standard CR2032 lithium coin cell.
