When the power is out and a source of light is desperately needed, a device that can convert hand crank power into usable energy would come in handy. That’s pretty much the main selling point of one flashlight from Simpeak.

• The LED flashlight features a hand crank that can generate 10 minutes of lighting from 1 minute of cranking.
• Easy to grip and has a built-in carabiner to hook to other items.
• It has a solar panel that can convert any source of light, including a lightbulb into electricity.
