Five hours of sun will produce 2.5 hours of continuous light with Energizer’s Solar Flashlight. It has an internal rechargeable battery that can be powered by the sun or by an attached hand crank. One minute of cranking will produce four minutes of light.
The flashlight includes a clip so you can attach it to a backpack or other gear. Energizer’s suggested retail price for the flashlight is $24.29. The company also produces a solar spotlight that can be charged with an AC car adapter and a solar-powered folding lantern.
