How long will the battery last running lights and fan by itself no solar, would like to know your experiences and what you were running?
I don't know, but some batteries are better than others. I never had a problem with lights, and the fan, I've never run it for more than maybe three hours in a day. I'm usually only out no more than three days at a time. As for lights in the five wide, i have them on a couple hours at night at most. I've run my 12 volt blanket, which is 45 watts, but it goes off by itself in a half hour, and i usually turn it on three times in the night if it's freezing out. You might check your battery status after running the fan a while.
Thank you guess I will have to do some tests before I go out camping.
