C Crane CC Solar Observer Wind Up Radio with AM FM Weather and built in LED Flashlight COBS

The easiest way to use the Solar Observer is to put it in the sun with the solar panel up. After charging for 8 hours in full sun, the Observer can play for about 4-6 hours depending on volume. Please keep in mind the melting point of the plastic is about 194° F. It should not be charged in a hot car or any other unusually hot places. The plastic can melt under these circumstances. No sun? No problem. Crank the handle moderately for about 90 seconds to get approximately 12 minutes of radio play, or purchase the AC adapter to charge the battery pack. If you purchased the AC adapter it is best to cycle the battery by plugging the radio in, charging the battery overnight and then unplugging it. It is also a good idea to “cycle” the battery pack every 4 to 6 months more »
