In the article, I will explain to you how to hand crank a flashlight work. Also, you will know some benefits and drawbacks of the hand crank flashlight.
How Does Hand Crank Flashlight Work?
The hand crank flashlight mechanism is completely different from a battery-powered flashlight. You can guess its mechanism by its name. This flashlight gets power from the hand-cranking mechanism which eliminates the need for batteries.
A hand crank flashlight works by using a small dynamo that is powered by the turning of a hand crank. The dynamo produces an electric current which is used to charge a set of batteries. The batteries then power the LED bulb of the flashlight. When the hand crank is turned, the dynamo produces an electric current which is used to charge the batteries. As the batteries are charged, the LED bulb produces light.
