use one of these for phone charging ( or similar they are often on sale)

Cheap and thrifty doesn't allow for A/C.
If you want to run the A/C on battery power you would need to spend $500 to $1000 for batteries, solar panels, power inverters, a cheaper easier alternative would be a small generator like the Honda EU1000. Quiet and you just plug in your trailer to it. 1 gallon lasts about 8 hours.

Socal Tom wrote:OK, so a little math and some rounding gets me to about 10 amps per hour at 120v, that brings us to 1200 watts. So I would probably plan on a 2000 watt inverter to cover these needs. 1200 watts for 8 hours is 9600 watts, which is about 800 amp hours at 12v. If you want the battery to last you should keep it above 50% power so let's plan on 1600 amp hours worth of battery. I use a walmart marine battery that has about 100 ah, so you would need 16 of those to meet the needs listed above.
One 12v battery will not carry an air conditioner for 8hours, but would be fine for everything else you listed assuming you recharge each day.

Double that for 32 ( again ditch the 60w bulb for an led that will pull much less) . just to be safe let's make it 50aH. So something like the above, or a goal zero yeti power station could be an easy economical device for you.

This issue aside, I have another question. Let's say I buy a 12v vent fan, like a Fan-tastic fan, then what would be the easiest way to wire it since I don't have a 12v system? I know I could use a converter. I'm perusing using a computer power supply. But would it be possible to use a ac/dc wall adapter (with comparable specs) and just plug it into my ac system then?
