Even if the power goes off, the 6-in-1 Personal Safety Device is still fully functional. It’s powered by a hand held crank and incorporates six of the most important tools you will need in an emergency. Super bright LED flashlight means you’ll never be in the dark (one minute of cranking provides approximately 1 hour of light). It’s also a cell phone charger, emergency FM radio, signal flasher, 130 DB emergency siren, and directional compass.
