My popup campers battery lasts most of the nearly week and half I'm at
osh. Mostly charging the cell phone, my implant batteries, and lights at
night for reading. I have a yamaha 1000watt generator for charging the
battery (I use a regular charger, not the wimpy "built in" charger in
the generator).

I don't use the battery for anything else. I don't bring a computer
cause of no network, and there isn't much to watch on a 9" TV unless its
really good and on VHS tape.
