Mod Description:

When the weather is hot and you don’t have an electrical power source to run your A/C , the next best thing is to get the air inside the RV moving. Ceiling vent fans like the Fantastic Fan are great for exhausting air from the RV but don’t do much in the way of providing that “in your face” cooling effect that a fan designed to provide maximum air circulation can. Pop-up or tent trailer owners know this situation well but for those not so in-the-know, that’s where the 12-volt cooling fan mod comes in to play.

Mod Difficulty:

There are a few different types of 12-volt fans to choose from: clip-on, stand-alone, permanent mount, multi-speed, lighted, or a combination thereof. And all generally come with a 12-volt adapter that plugs right in to any 12-volt receptacle typically found in your RV.

The clip-on type is about as simple as it can get. A large clip is provided to secure the fan to most any cabinet or counter edge. Simply clip and plug. The stand-alone is just that. It has feet on the bottom of the fan housing to support it so you can place it on a shelf, counter top, or even the floor. These types usually have several speeds to select from but tend to draw a little more power from your batteries than a single speed might since on high speed, they flow much more air. However, you can regulate power draw by selecting a slower speed.

A permanent-mount is similar to the clip-on type but instead has a bracket to secure it to whatever surface you desire. Bunk beds are usually a good candidate for these types since there really isn’t anything to clip the fan to. Under a cabinet in the kitchen is another popular place as well. Just be sure that wherever you mount the fan, it’s near a 12-volt power source. If not, you will have to either install a 12-volt receptacle or run new wiring to the fan.

Finally, you can take a page from the book of the good folks who own popups. Most popups come standard with a combination fan. This fan has two speeds, a light, and an electrical 1/4″ connection plug that fits into a ceiling-mounted receptacle. It’s used primarily to circulate air in the tent ends of a popup or hybrid trailer. But you can fit one to your RV and reap the same benefits, just in a bunk or bedroom instead.

    We added 2 fans to our camper, one like the black one pictured here and another square one made by RoadPro. Both are 12v, the black one is hard wired and the other plugs into a 12v receptacle we added above the sink (which we also use for our 12v appliances).

    Is it possible to connect any of these fans to a 15Amp solar panel
    with a little bit of modification.

    Do you meen 15 watt solar panel? If so …..No Not enough current to run the motor. Just connect to your batteries or any 12 volt supply in your rv.

    [...] In another mod, we talked about how to keep cool in your RV by using clip-on, portable, or permanent-mount 12-volt fans. These are great for distributing air in certain areas of your RV, like a bunk area. The Fantastic Fan mod is for moving a lot of air through your RV in a short period of time. This is just the thing to get out that burnt popcorn smell or the “I hope no one can smell that” emanation coming from the bathroom. [...]
