Emergency Radio - 8" x 2 1/2" x 5" I bought this about twenty years ago to keep in my earthquake emergency kit. While it can run on batteries, this radio can also be charged via its built-in dynamo which is charged by turning a handle. One minute of turning at 24/rpm yields about three minutes of radio time. There is also a 5-light bright LED flashlight built in. I presume this still works. For all of the wildfires and earthquakes and hurricanes out there, this might come in handy.
