A Guide to Caravan Fans: Keep Your Motorhome Cool in Summer

Staying cool in the sweltering Australian summer is tough, especially on the road! Sure, you can turn on the air conditioner, but that means relying on a noisy generator to keep it powered through the hot hours. Moreover, not all caravans have an air conditioner – in fact, small ones usually don’t which further complicates things.

Good news? There is hope as long as you have access to a 12V power source. Numerous portable caravan fans are available these days and they offer efficient, economical cooling wherever and however you set up camp.

If you’re on the lookout for the perfect cooling solution for your next summer camping trip, a flexible and portable low-voltage 12v caravan fan will keep the air moving inside your camper vans and make all the difference between a sweaty night and a cool, great night’s sleep!

However, many people struggle with finding the right caravan fan for their motorhome because they’re not sure what to look for! For that reason, the following guide takes into account all the important factors one needs to consider when purchasing a caravan fan as well as some of the best fans on the market today and why.

Power consumption

Knowing the power consumption or how much current a 12v fan or cooling device draws is crucial when choosing one for your caravan while camping. Normally, this will be specified in amps and listed in the product specs. The smaller the current draw, the better for unrestricted camping.

A battery with a 100 amp-hour capacity can theoretically run a fan for 100 hours at 1 amp or 1 amp per hour. That fan will consume 10 amp hours, or 10% of a 100 amp hour battery if it’s left running overnight for 10 hours. That might not seem like a lot, but when you take into account the power requirements of all your other 12V devices, the total soon mounts up.


When picking the ideal type of 12v caravan fan the main question to ask yourself is whether you want to purchase a portable fan or permanently attach a fan to your RV. Moreover, consider where you plan to use the fan. Are you merely looking for it to keep you cool as you sleep or do you spend a lot of time in a small space where you have to keep everyone comfortable during the day? The following types might be exactly what you’ve been looking for:

Mountable caravan fans give you the freedom to mount wherever you need them. Choose a 12v fan with cables if you need permanent mounting.

Portable fans, on the other hand, might be relocated anywhere you need to cool off because of their small size and portability!

Oscillating caravan fans rotate as they move to circulate air over the entire space.

A caravan fan with a light is proof that brands have nowadays gone the extra mile when it comes to comfort and style to provide you with the ultimate camping experience. You can get all the necessities for a warm summer night when opting for this type of fan!

Whatever type you decide on, keep energy efficiency and lightweight construction in mind!

Speed Fans

A variable speed fan may be costly but it’s a worthwhile investment as it comes with several undeniable benefits. During the day, you can turn up the chilly air, and at night, you can lower it down. Their power draw ranges from 0.13 to 0.36 amps, depending on which of its three-speed levels you choose. This implies that you could run two-speed fans continuously at maximum power throughout the whole night and still not run out of power!
