Coghlan's Dynamo Flashlight is a handy little device that uses a built-in wind-up handle to power itself. Bring it with you on the go or hook it up to your backpack on outdoor treks with the attached keychain.

Why choose this flashlight?

• Wind-up design ensures light even without any batteries
• One minute of charging produces a 7-minute runtime
• Keychain for attaching to bags or belt loops
• Compact design adds no weight to your pack and can be stored anywhere with ease

Why not?

• 10 lumen beam output not ideal as a long-distance searchlight
• Low runtime in between charges

Pro Tip:
Lumens are a measure of the total visible light emitted by a source and are the current standard for measuring the power of flashlights and lightbulbs. Wattage used to be the standard, but this unit only represents energy use, and modern energy-efficient LED lights can generate a lot of light with minimal watts.
