Wiring an Inverter to Run a Small Fan in Bedroom

We use these in the bedroom and over the dinette.

They are actually designed for a tent I believe.
It operates on 12v and has a portable 12v source if needed(haven't used).
We ran a lighter adapter plug to the nearest light to plug into the RV 12v.
It also has a magnetic base that we mounted above the bed. It lets the light hang down and can be rotated, adjusted or removed simply by pulling it off the magnetic base.
They are pretty quiet.
I recommend them.

Only the rear? :) Or maybe you meant that there are no plugs of any kind in the rear, neither 12V nor 12V, - in this case you should add some.

1. Is there an easier way that I'm not thinking of (besides using a battery powered fan which will not be strong enough and will require constant supply of batteries).

12V fan. Like Endless Breeze - freestanding, or one of their models mounted in the roof vent.

3. Will running a fan all night drain the entire house battery overnight (does anyone know what kind of draw a medium size fan would pull on the battery?)

There are specs on Fantastic site, not very detailed but should be 1.5-2.0. on the medium. Which means in 8 hours it will draw about 16 Ah of charge. Since you should not draw more than 50% from the battery, this leaves you very little for your other needs. So you need either a generator in the morning, or a solar panel.

Hi, I also need a fan to sleep. I have tried the 12v fans, either they don't last or they are not loud enough. I use the inverter to power a small table top fan. Allthough I have 4-6 volts in the trailer, I use a group 24 when I use the tent and it has not failed me yet.

Again, you guys are awesome.

MexicoWanderer, I need a fan for both. A nice breeze as I get hot when I sleep and also for the noise which soothes me to sleep. I have a weird body in that if I don't have a fan going at night (even during winter), I tend to get too hot.

A fan for air or a fan for the soothing noise. A 12 volt muffin fan is small, moves air and is a fraction of the size of a truck fan or even a Fantastic Endless Breeze. Most of these fans are square so no mount is needed and many push a lot of air for 10 watts, under one ampere is consumption. In the morning open the drawer and in it goes.

surpluscenter.com has a lot of these fans in various sizes. Inexpensive. Use the scroll menu on the left to navigate. A 10 watt fan makes a nice soft whooshing sound and pushes enough air to satisfy a person unless you must have air blowing on your ears and toes.

In Mexico I used to use one of these fans with a blue light just behind it to suck in flying critters and macerate them out on the patio.

Look around the bedroom where the bedroom TV connects to a F-connector. Some have this TV panel located here as well


This same panel should also be located in the living room as well close to where the TV is located.

The cigarette 12VDC connector here is low DC amps and should be ok to run a small 12VDC fan.

However I really like the O2COOL fans. These are available from WALMART-LOWES and are 10-inch fans I think and will work from both 120VAC using a transformer or from internal D-CELLS batteries, or from a 12VDC cigarette light plug

You will get a lot of air moving from these fans. These are great to have around for anytime you might to move some air.



Also my trailer has the large fanstatic fan mounted in the ceiling that runs from 12VDC... Might give that a try as well...

If you really want to add a small 300WATT PURE SINE WAVE INVERTER it is doable as well. The best place is to mount one is as close as you can get to the battery connection. I started out with a 300WATT unit then went to a 400Watt and finally ended up with a 600WATT unit. You always find something to use on 120VAC it seems. Alot of folks will mount one in the pass thru storage area which is usually right behind the front wall where the batteries is installed. These can be mounted on the wall and have the proper fuse installed etc. Mine is a remote ON-OFF model...

Then you would want to run two 120VAC drop cords with multiple 120VAC ports on them from the two 120VAC receptacles on the INVERTER. One to the bedroom night stand area and the other one to the home entertainment area. No cables will be seen by anyone just the multiple 120VAC ports on a table top will be visible. Then you can plug in 120VAC small wattage things like the HDTV , DVD, small fans, cell phone charger, computer charger etc for use when you are camping off the power grid. neat to have when you need it...

This is typical smaller trailer layout showing the idea discussed here.


Just my thoughts

If you have a 12v outlet in the bedroom, most RV do, use a small (100w) inverter to run a small 120v fan.

Hi,

The 02cool series has at least some fans with built in rechargeable batteries.

02cool battery with adapter

I use the O2Cool fan with regular batteries. Works great even on low. Supposedly runs 35 hours on high on battery. I haven't tested that yet but it did run every night, all night for a 3 day weekend. It also runs on 120V. The rechargeable fan doesn't run as long as far as I know but you can recharge it. I figure the battery operated one would be fine for a weekend trip. I got it for $25 at Rite Aid. I'll likely get another one.

I'm going to second the "Endless Breeze" 12 volt fan.

Do you have Fantastic Fans installed in your RV? They may also serve your need. I set mine to exhaust and open a window or vent near where I'm sitting or sleeping. A nice breeze comes in that window. For this to work the other windows need to be closed.

I find two Fantastic Fans exhausting can create a good draft through open window. One is plenty for a light breeze when sleeping. And it can be far away from the person so minimal sound.

I have the same fan and highly recommend it. It is a little pricey but comes complete with Fantastic Vent's reputation and superior customer service. I believe in buying a quality product and buying it once. Some people prefer to buy a cheap product and then buy it again, and again, and again. Buying quality saves money in the long run.
