Best Portable AC for Camping: Stay Cool in the Heat!

Best Portable AC for Camping: Stay Cool in the Heat!

Most RVs have built-in air conditioners, but many people travel in older rigs without working AC or in self-built camper vans. Still others use camping tents or even minivans, SUVs, or cars for camping purposes. For these travelers, a portable AC for camping may be the answer to the discomfort (and danger) of camping in the summer heat.

Today we’re taking a look at portable air conditioners for camping. Let’s jump right in!

What to Look for in a Portable AC for Camping

There are a few things you’ll want to take particular note of when you’re shopping for a portable AC unit for camping purposes.

Type of AC Unit

First, there are different types of portable air conditioners, and the type you choose will depend on the style of camping you do, the size of the space you need to cool, and the amount of power you can support with whatever power source you have.

For example, if you use a tent for your camping trips, there are portable AC units that are specifically targeted to tent campers.

But in truth, most tent air conditioners aren’t very efficient. This isn’t so much about the cooling effects of the AC units as it is about the breathability of most tents.

Evaporative coolers are sometimes used as tent ACs for serious tent campers. But it’s very difficult to efficiently cool hot air in a tent unless the tent is truly airtight and has some reasonable amount of insulation.

As a result, a camping fan (or two or three!) will be the way to go for many tent campers.

For most tent campers, a decent fan or two, rather than a portable AC unit, will be the most efficient approach to cooling.

Power Source

When running any appliance requiring 120V electricity, especially air conditioners, your power source is the key issue.

This won’t be an issue if you’re connected to shore power when camping. But if you boondock, you’ll need a capable power source to run an AC unit.

For example, in some Class B RVs or vans, you’ll sometimes see a window air conditioner used. But your ability to power a window AC unit (or any other type of AC unit) is key.

Do you always camp tethered to shore power? Do you intend to boondock and run your AC using a generator?

You’ll need to consider these important questions when choosing a portable AC for camping.

Weight and Space

The amount of space a portable AC unit (and accompanying power source) takes up in a small RV, van, or car is a very significant consideration. Space is at a premium in smaller camping vehicles (less so in tents, perhaps), and a large portable AC unit is unlikely to be the best choice.

And as always, weight is a significant consideration. Not only do we need to keep the weight down as much as possible to comply with the safety standards of whatever vehicle is serving as our home-on-wheels, but anything that’s portable needs to be able to be moved… by you.

So, carefully consider the weight of any portable AC unit you’re considering.


How the unit operates is a necessary consideration when shopping for a portable AC for camping. For example, some portable AC units require water to run. Whether you’ll have a water source to keep the AC running is something to consider.

Also, while many portable AC units drain through the exhaust, with others, you’ll need to empty a container that holds the water produced by the air conditioning process. How frequently it needs to be emptied is something to keep in mind. If you intend to run an AC unit at night, pay close attention to how frequently reviewers state they had to empty the reservoir (which will vary, depending on how humid it is where you camp).

Even if you’re connected to shore power and can run your AC all night, you don’t want to be forced to get up every 90 minutes to dump a container of water. You’d be better off using some of the tips in our article on how to keep an RV cool in summer.

Finally, note that most portable AC units (other than evaporative coolers) will require venting to the outdoors. That’ll also need to be a consideration as you choose a portable AC for camping, especially since many RV, van, and other vehicle windows aren’t particularly conducive to venting an exhaust tube to the outdoors, so some modifications may need to be made.

BTUs (Cooling Capacity)

Cooling power is an important consideration when you’re shopping for a portable AC unit.

A BTU (British Thermal Unit) is technically a measurement of heat. So, in the case of air conditioners, the number of BTUs reflects how much energy the air conditioner uses to remove heat from your rig within the period of one hour.

But what you really need to know about BTUs when choosing a portable AC unit for camping is that the larger the space you’re trying to cool, the higher the number of BTUs you’ll need.

For example, most portable air conditioners marketed to van campers (and tent campers) will have anywhere from 5,000-12,000 BTUs.

If you’re trying to cool a small van (or a 2-3 person tent, according to manufacturers) with a living space of maybe 10 square feet or so, a 5,000 BTU AC unit is likely to suffice.

However, if you’re trying to cool a much larger camper, you’ll need a more powerful unit that produces 10,000 BTUs or more.


This one might be a bit difficult to get away from because most portable AC units will make some noise. But keep an eye on user reviews to get an idea of how “quiet” portable AC units advertised as “quiet” really are. Some can be very loud.

Be sure to check user reviews for real-world responses regarding the noise level of a portable AC for camping. A loud appliance in a small space like an RV or van can quickly make you regret a purchase.


Some portable AC units combine the cooling unit with a dehumidifier. This can be important to the cooling process and air quality, especially if you camp in high-humidity areas.

Note that while a dehumidifier is a nice feature to have in a portable AC for camping, it’s also likely to make the unit even more power-hungry… AND more user UNfriendly due to the fact that you’ll likely need empty the collection reservoir more frequently.

So here again, if you’re usually tethered to shore power when you camp, the power issue may not concern you. If you need to conserve power, be sure to check the power requirements carefully if you’re looking at units that include a dehumidifier and check user reviews for how frequently the unit shuts down because the reservoir needs to be emptied.

Note that some AC/dehumidifier combination units can be used only in fan or AC mode, not requiring the use of the dehumidifier.

A Note on Evaporative Coolers

Note that we’ll be staying away from highlighting evaporative coolers in this post. For one thing, our research indicated that most people were sorely disappointed in the performance of commercial evaporative coolers, having expected more air cooling than they were getting.

However, an evaporative cooler is really best for use in very low-humidity environments.

That’s because they work by using a fan to pull in hot air and circulate it over cold water, ice cubes, or a wet cooling pad. The idea here is that the now-cooled mist is dispensed into the air, making the air cooler and more comfortable. But also more humid.

We’re not sure how well these would work in a tent environment, but moisture is a real enemy in an RV or van.

Moisture tends to build up in a small, closed-in space like an RV or vehicle, and the more moisture there is (in addition to the moisture from breathing, cooking, showering, and the ambient humidity), the more likely the development of mold and mildew which can eventually cause serious issues.

For these reasons, rather than investing in an evaporative cooler, you can try a personal mister, check YouTube for how to DIY a “swamp cooler” (but you’ll still have the moisture issue!),  or you can check out our article on how to stay cool in an RV without air conditioning.

Portable AC Units for Camping

We’ll note right from the start that portable AC units for camping often get lots of negative reviews. Of course, we’ll avoid highlighting any of those with a majority of negative reviews.

But it’s important to note that there are many issues that people can have with portable ACs for camping, including non-airtight tents, moisture or venting issues, and the fact that air conditioners tend to be power-hungry appliances.

This post will highlight only portable AC units with 80% or more 4- and 5-star reviews. Even so, all of these units tend to have 5% to 8% of very negative (1-star) reviews. A portable AC unit is just one product that performs well or poorly, depending on the application.

We recommend reading reviews carefully with your particular application in mind.

With all that said, let’s take a look at some of the best-reviewed portable AC units currently on the market.

COSTWAY Portable Air Conditioner

This portable AC features four different modes of operation (ventilating, drying, air cooling, and sleep mode) and two fan speeds.

It’s available in either an 8,000 BTU or 10,000 BTU model. Both offer a 24-hr timer and come with a window venting kit (which, again, may need to be modified for an RV, van, or other vehicle).

According to the manufacturer, the 8,000 BTU portable air conditioner is a 920-watt unit and should cool a floor area of 230 sq ft. The 10,000 BTU air conditioner is a 960-watt unit and should cover a floor area of 350 sq ft.

Both Costway AC units come with remote controls and have dimensions of around 12 x 12 x 27.5 inches.

What About Portable AC Units for Tent Camping?

The reason you’re not seeing a list of AC units that are dedicated for tent camping is that our research yields overwhelmingly poor reviews for them in general. We looked at many of them, and they all had high percentages of 1-star reviews from users who said they were mostly a waste of money.

Many tent campers said they’d tried several different products heralded as ACs for tent camping, and in fact, they felt they were better off with a good fan.

Many products advertised as portable AC units for tent camping basically amount to personal misters at best… evaporative coolers that mist cool water.

Once again, some decent camping fans, along with a self-spray mist of water or a cool cloth rubbed on the body, are likely to do just as good a job of cooling you off in a tent.

Final Note

For RVers or van & car campers, there are many portable AC units on the market in addition to the five we’ve highlighted above.

The key is really how much space you have to accommodate a portable AC unit (they’re fairly large for a van, for example), and the amount of power you have to run it.

Meanwhile, here’s a tip: Consider boondocking whenever the weather is conducive to camping without AC, to save your money for a campsite with full hookups, including shore power that’ll support your portable AC unit when the weather is uncomfortably hot.

In that vein, here are our 11 best ways to find RV boondocking spots!


Never leave your pet in your RV or van with a portable AC unit running, assuming your pet will be safe.

These units shut down for all sorts of reasons (including a full reservoir from dehumidification), and we know you wouldn’t want to endanger a beloved pet who is helpless if the AC shuts down and the living space heats up quickly.

I have seen several travel trailers that use a window mount air conditioner . It looks like they take a window out and frame the unit in and then remove ac and put window back in when they travel.
