when dry camping or post hurricane we find many uses for a 12v battery.... I find rechargeable ones at the dump..10% are o k....when camping i take just 1 for a 12v lite and radio.....with summer coming a after lunch nap is s o p...however the p u gets warm at mid day,so a small fan is in my future.......my question is, would there be less drain on my ''loose standing'' battery by using a small 12v fan,or by a same size 110v fan running from a hand size 100 w converter hooked to the battery??

A small 12V fan would be far more efficient.
An
INVERTER (not converter) will consume more power to do the same job. There are some very efficient 12V fans on the market.
Run over to Walmart and buy one of their "O2Cool" fans that take D cell batteries. The crank out the air (2 speeds) and run forever on a set of batteries. There's a big 10 or 12" version, and a smaller 5-6" version that takes AA's. We've got both and love them.

I agree, the 02 Cool fans work great. I have two of the 10 inch (black) ones (run on D cells or 110).
I also have 4 of the smaller 5inch versions. All of them work great.
A really nice 12 volt fan is the Endless Breeze by Fantastic vent. Here is a link to their website. I have had one of these fans for years. It moves a lot of air.

I'd agree with the O2Cool fans. I paid a bit more and got the one that has a rechargeable batter in it as well as can run off the D batteries and regular 110. So for a weekend I make sure it's charged up. It will run all night on the rechargable and then will run off the D's the rest of the time. If we run the generator during the day for a couple hours to top off the PUP batter then I'll recharge the O2Cool as well. Works great!
We picked one of the O2 fans at walmart as well, The 10" one we found runs on "D" cells, 110V, and 12V with a car plug. It works very well.
If you have a Kroger market in your area, they have the summer stuff half off. I picked up an O2Cool fan there for $10... nice little fans.
12V is the way to go! In any case, a typical converter will draw 5W off your battery when it is plugged in and not running an appliance so that's strictly last-resort unless you're carrying more than one set of golf-cart batteries. I like the type of fans (and 12V lights, pumps, etc.) found at CampingWorld, rugged and drop-proof.
I have 2 of the 250s, but they now have a 400. It comes with 12v and 110v outlets, plus a few other features. Endless Breeze fan works great on one of these.

Beware that as rechargable power supplies, these are junk. I barely got 1.5 seasons out of my WAGAN 400. Inside these devices are tiny lead-acid motorcycle batteries that are designed for starting cars, not deep-cycle use. Fortunately I was able to get a full replacement under warranty, and the thing is now on a shelf for what it was intended for: jump-starting a car or inflating a tire, not use as a power supply. If you need a power supply, you need a 12V house battery. It won't cost much more, but will pay for itself many times over compared to these power supply jump start devices.
