The CC Observer is a wind-up emergency radio that makes no bones about outperforming a distant cousin. You might notice that we did a few things differently. For one thing, we tinkered with the AM for better reception, and then we put the LED flashlight on the side of the radio instead of the front. That way, when you turn it on the light doesn't shine in your face, and when you carry it, you can use the flashlight to light your way while holding it in a more natural position. You can run the CC Observer off the built-in rechargeable batteries, 3 "AA" alkaline batteries (not included), if you prefer. Our optional AC Adapter can charge up the built-in rechargeable batteries, using regular house current. Of course, you can just wind up the radio and keep it running as long as you need. You can even use the radio to charge a cell phone.
