Now you can generate your own power with this dynamo hand crank. By quickly turning the handle, you can generate voltage up to 5V depending on how fast you turn. There is a gearbox inside this dynamo that steps up your RPM drastically so the motor will spin much faster with less cranks to generate power. You can build a small generator with this, powering up a couple of small LEDs. It is great for projects that requires conversion of energy into power.
You can also use this as a reduction gear box by connecting a battery to the motor directly. This will rotate the handle but with a much larger torque.
