This state of the art dynamo 4 in 1 flashlight includes 3 bright LEDs, Am/Fm radio, emergency siren, and cell phone charging capabilities with an adapter. All of these features are crucial in keeping safe as well as supporting your ability to maintain communications while waiting out the storm or until help arrives. Never run out of power as the hand crank allows you to re-energize on an ongoing basis. The high-efficiency dynamo system allows one minute of winding to create enough power for 1 LED to last an hour and a half or 3 LEDs to last for 30 minutes. Winding for 3 minutes will give your cell phone 2-8 minutes of talk time. Great tool for every home, automobile, RV, boat, office, and school. It never needs batteries! This cord is not a USB cable. Dimensions: 7.5 x 2.3 x 2.3
