Regarding your reefer Steve91T... it is entirely possible that yours will be a-okay without power overnight. Provided of course that it is nearly full AND you don't open and close it.
When power was tight I often would simply shut off my inverter (an AIMS from http://theinverterstore.com incidentally) and then turn on in the morning. Folks that Know here (the Electric guys) tell me that I am using more power by doing that. Still, it is what I did do so there you have it.
As for MSW (cheap) versus Pure Sine wave inverters: Pure is the way to go (and believe me, I like inexpensive) ... the thing is, anything digital won't work. There's reasons (above my knowledge level) but as a rule digital and cheap inverters do not cooperate.
My microwave spins, makes an odd noise and does not heat on the cheap inverters.
In any event, you might consider simply wiring in 12 volt fans and using a cigarette lighter (male) with built in USB ports for charging your phones. Just a thought.
If your 12-volt outlets have two holes, that is the old style. Still in use, and you can get males to use them. A multimeter (set to DC, then #20) will show you if you have any power there. It will also give you your battery voltage. This will not tell you how much power you can get out of that outlet -- for that you'll need to see what your wire gauge is, check fusing, etc.
Anyway, good luck.
