This mini hand crank solar flashlight is your on-the-go emergency light! You can bring it along even to simple activities like biking, jogging, and night walks. When you run out of solar power, you always have a backup source with kinetic energy. One minute of cranking instantly produces 10-minute lighting that can be as bright as your AAA battery powered flashlight.
It is indeed a must-have for your emergency and camping kits, and besides, with continuous use, you can have a stronger hand grip.
