This small and affordable DC crank generator features a 5V USB connection port and can be used to charge and power a wide variety of electronic devices. Just pull the hand crank out and spin it; a red LED next to the connection port will let you know that you're generating power. The unit also includes a wrist strap to prevent breakages. Bring it camping, or have one around the house handy in case of emergencies or power outtages.
Plug your Android phone and tablet or your Apple phone and iPad using your existing USB charging cable or use an included USB to 5.5x2.1 mm DC power cable to power your other devices or science project circuits.
