The Coleman Units are not too bad. Let me qualify that and add for specific applications. We run them semi-permenantly mounted in our 4x4s using an external anntena. You can get them with optional AC/DC adaptors which allows you to use them 12volt vehicle or 120volt house systems without using batteries. The FM radio gives about 30 kilometers. AM is unlimited depending on conditions. TV is marginal, at best. Light is OK but as other posters mentioned, they suck juice like a dehydrated fish. They are not constructed to take much punishment.<br><br>Mariner
