Generator and dimming lights

The bathroom vent fan is 12v, so you have that.  You can also get battery operated fans.  Walmart usually has them in two sizes.  They work fine for a long time.  The big one takes 8 D batteries though.

This isn't for everyone, but if you have 30v cordless DeWalt tools. DeWalt has a 20v fan that is great.  It's overpriced, in my opinion, especially if you have to buyu a battery and a charger. 

An inverter is a gizmo that usually plugs in to a cigarette lighter kind of 12v outlet and converts 12v DC to 120v AC.  If you have a way to plug one in in the Pod you can plug in something little anytime.  They come in all sizes; without really knowing what you are doing, you don't want one any bigger than about 200 watts, maybe 400;  That will let you charge your computer, plug in a TV or a fan, but it won't come close to letting you use the microwave, A/C, or a hair drier. And if you have much plugged in, they will suck the juice out of your battery fairly quickly.  (That's one reason to limit the size to about 200 watts.)  You can pick one up at Walmart or just about anywhere.

We do the same, mostly camping in the woods in Colorado and Utah. If you add a fairly long cord (20-25 ft) to your solar unit, it can be moved around to take best advantage of the sun. Usually I move it 2-3 times during the day. Keep pin mind that you still get some benefit even if not in full sun, just not as much. Our house has a solar system and I'm always surprised at how much benefit we get even on cloudy days (sort of like why they tell you to wear sunscreen even on cloudy days!).

I have an O2 Cool fan, but a different model than the one Ben linked.

The fan and AC adapter are included. It uses six D-cell batteries. I found that it will run on a 12V adapter as well but it is just a little louder as it is running faster. It moves a nice amount of air. We use it at the base of the bed to help circulate heat from the furnace in our 179. I had the 12V cord from a RoadPro fan that was making bearing noise, so I replaced it with this model. I actually found it at my local Staples store for less than the Amazon price but they appear to have been discontinued.
