This self-powered flashlight is perfect for keeping in the car, since there are no batteries to worry about. Or, keep one in your backpack for camping, hiking, fishing, etc. Stash one in your kitchen drawer for when the power goes out. The compact & lightweight design makes this flashlight useful for just about anywhere. The bright LED lights are powered by simply squeezing the handle a few times, and unlike some self-powered flashlights, this one doesn't require constant pumping to stay lit. It features an on/off button for when you need a constant light.
