This pistol grip style handle generator can be utilized with almost any experiment requiring 12-Volt DC current.  Housed in tough clear plastic so that energy transformations may be followed from the crank to the electrical outputs.  This generator may also be used as a hand generated flashlight due to the mounted lamp (included) on the end or use the binding post to connect an outside electrical circuit. Dimensions: 6.5" x 2.5" x 4.25".
