Running a fan on an inverter

For overnight usage I would go with a 12V fan. As to what unit, it all depends on the amount of use you intend to give it. If you overnight often and intend to use it a lot get a quality fan. On the other hand if you will only use it occasianally you may want to go with an inexpensive clip on. The Walmart automotive 12V fan draws 0.8 amp per hour and sells for around $10.
I gaurantee you if I bought a fan with out a gaurd on it I would stick my head in it with in the first hour of installing it.
We got one at an auto store, 12V cigar plug, bought an extension cord. It also rotates! $10!
12V is a no brainer - don't use the inverter.

I have two 12V fans in my boat. One West Marine one that tends to blow a descent amount of air and then one that is mounted in my V berth that really don't move all that much air. That being said, the one on the V berth isn't that expensive and it does move enough air to help with hot temperatures. I also like the white noise of a fan running so I tend to run mine a lot.
I have a two battery house bank that are group 27s. I do not run refrigeration on my boat so there isn't much power consumption going on. I have my house bank on a Link 10. I can run the fan in the V berth all night, the cabin fan for most of the afternoon, a small inverter to power the lap top, and the anchor light and I am usually at 98% or 97% in the morning when I get up, according to the Link 10.

Cheap fans
The cheaper walmart type fans are a bit noisy and don't use at night I also have three marine type for at night,was in WM recently and they have some new fancy fans that really push some air yes they are $$$$$ but you get what you pay for.

I decided to try this one:

At 1 amp I'm hoping it will move quite a bit of air, and that's still only 8Ah over night drain.

We had one of those, don't expect much and the metal cage rusts really fast. Chuck
I have the honeywell and the same inverter, I just ran it for three 8 hour nights. I'll have to check the batt voltage. I also ran a 9 watt compact flourescent for an emergency anchor light when mine failed to work.
I have two of these on my boat and they work great on AC but I have only used it one night solely on batteries so I can not testify to the 40 hrs claim.

They make a model that works on AC DC, and Batteries too. IO bought mine a at Lowes .

O2 COOL Fans 12V
This is a delayed response, but I have become fan (pun intended) of these fans. They draw very few electrons and quietly move a lot of air. They can be run on D-Cell batteries or wired or plugged into your 12V system. The price is far below anything you will find at the marine supply stores. Some are even meant for outdoor use. I found mine at my local Drug-Store for less than $20. Lowes has them as well.

Carframo Fans are excellent....
We use one of these:
http://www.caframo.com/marine/marine_products_12voltfans_kona817.php
It is 3 speeds and draws 0.21, 0.26, and 0.37 amps on low/med/hi.
The fan moves quite a bit of air - waaay more than the ones that run on 4D cells.
Current draw is almost negligible - I run a 260AH house bank (also with refrigeration - Isotherm ASU - which also is super efficient).
Running the fan on HI for 12 hours only consumes 4.4 AH.
For me - the "air moved" vs "power conservative" equation makes these fans great for cruising.
