mpruet said:I don't think you would need that much power if all you are going to run is a fan. You could get a DC fan which plugs into a cigarette lighter and then a 12-volt clamp connection between a 12-volt battery and a single cigarette plug. That way you could avoid having to purchase an inverter. If you are going to want to run other things which are going to require alternating current, then you would need to get an inverter. I'd strongly suggest getting a pure sine inverter because a lot of electronic devices won't work with a modified sine wave inverter and fans will buzz.
But like I said, you might be able to lower your costs by going with a DC fan and they can be found at most truck stops, a 12 volt battery, 12-volt to cigaratte adaptor, and a solar panel kit.
But truth be told, you need to first get a list of the things that you really need to power when you are remote first. And then you need to think of what the minimum that you need is with the idea of making it into something that can be expanded later once you've built up your financial reserves.

Right now all I have is my cell phone which drains pretty quickly a few hours of idling it is a cheap phone. I planned on getting an ipad or some type of tablet to watch netflix on, and of course a fan. I thought about just using the car battery but not too sure how much it would drain for 8 hours of running the fan 12v fan .
