The Energizer Solar Crank flashlight never needs batteries: you can charge it leaving it in the sun1 or hand-cranking it – 1 minute of winding provides 4 minutes of light, and 5 hours in the sun allows for 2 hours of usage of its 3 LEDs.

When you need light in an emergency situation, you won't want to funble with batteries. Or have a hard time finding it in the dark. This brightly orange-colored flashlight has its own carabiner, so you can fix it to some internal hook on your bug-out bag, or even outside, specially when you are using it.
