Strong, reliable, and easy to use, Coleman's StormBeam Flashlights are designed specifically for use during power outages, storms, and other emergencies. The StormBeam Dynamo Flashlight With Radio features a built-in FM radio to help you track weather reports and developing emergency situations. The StormBeam Dynamo has a built-in hand crank to recharge the flashlight with no outside power source, so you'll always have light when you need it. Just one minute of hand-cranking yields 30 minutes of useable light. The Dynamo's ultra-bright 5MM LED sheds strong, reliable light and will never need to be replaced. The flashlight's NiMH battery pack (included) offers consistent charging. Includes a 3-year warranty.
