Mini Dynamo Keychain Light
Tiny, powerful, dynamo. Unique eychain flashlight is just 1.75" long, 1/2" thick. It has a dynamo hand crank to charge the on board battery, powering 2 LED lights -- hard to tell from the picture, but it's pretty bright for just 2 LEDs.
Strong enough to allow you to see an entire room easily. 1 minute of cranking time (which is very easy on this tiny unit) produces 15 MINUTES of light. A great little product.
