If you need an air conditioner for your RV, you might wonder, can you use a portable AC in an RV? Sure, you could choose a roof-mounted unit, but portable units offer some advantages that you should consider if you haven't already.
As the name implies, these ACs are easy to move around, unlike roof-mounted versions. That means you can not only just use it in your RV, but in your house, shed, office, or garage as well! They are also much easier to set up than roof units - no carving holes or climbing on top of the RV is required!
Our list of top portable RV air conditioners is sorted by BTU output to help you find the right model for the job. No matter which one you consider, all of these units come highly rated.

What's the Best Portable Air Conditioner for an RV?
Finding the best portable AC for your RV is really a matter of matching your needs with the appliance. Firstly, you'll want the appropriate BTU output for the area you intend to cool. Here, we've selected the best model units for 14,000 to 8,000 BTUs covering square footage from 600 to 200 feet.
Secondly, you'll want to pair the AC's size and functions to your travel style. As you'll soon see, many portable AC units feature timed settings, digital displays, remote or Smartphone controls, and dehumidifier and fan settings. Plus, portable AC's are lightweight for easy set-up and storage so you can find the right size for your rig.
What Size AC Do I Need for My Camper?
The good news is, for an RV of 32' or shorter, you'll only need one AC unit to keep cool. The best way to size your AC unit is to consider how many BTU's you'll need to cool the area. Between 12,000 and 8,000 BTU's are the most typical of small to mid-size RVs and campers both for cooling capability and amperage. You should consider whether you are cooling an open area or segmented rooms, and where you intend to travel for best results when sizing.
14,000 BTU Air Conditioners
At the top of the BTU spectrum, we have some of the best and most powerful portable ACs on the market. Of course, these ACs are larger, heavier, and more expensive than the other options, so in this case, more isn't always more. Make sure to find the air conditioner that fits the size of your trailer. To help you out, 14,000 BTU is recommended for an area of 500+ square feet. For example, this Tiffin Zephyr motorhome is approximately 500 square feet.
1. Amazon Basics 14,000 BTU Portable AC
This portable AC is remote control operated, so you can stay comfy if you need to make any temperature adjustments.

A dripless exhaust system keeps the air fresh, and hot air is dispersed via an expandable exhaust hose (simply run through the nearest egress, either window or doorway). This lightweight AC features wheels, so while handy for repositioning, you'll want to secure the appliance before moving your RV. Click here to see on Amazon.

How to Vent a Portable AC in an RV?
Most portable AC units come equipped with an expandable hose and window frame fitting, so you can ideally ventilate through a nearby window. However, if a window is not within easy access or does not slide open, creative owners have devised other methods for ventilation like cutting a hole in the floor or sidewall, affixed with a deck fitting, to run the ventilation hose through.
You can also purchase a vent-free portable AC unit. Although it is recommended for these models to improvise a water catchment and ventilation system as not all of the water circulated evaporates, so it can end up on your floor. Vent-free units work best in dry climates.
Can you put a mini-spilt in an RV?
A mini-split AC is an affordable, compact solution to keeping cool. Most smaller units, at 9,000 to 12,000 BTUs, can sufficiently regulate a 500 square foot area. Mini-splits are efficient using low amperage, and offer simpler installation than rooftop ACs, being mounted on a trailer hitch mount outside or on an interior or exterior wall. There is wiring involved and copper line installation, so if you are not typically a DIY RVer, you might prefer to consult an electrician for this job.

Can you Put a Portable Air Conditioner in a Tent?
Absolutely! You can use a mini, portable air conditioner in a tent. Units that provide 5,000 BTU's should suffice, and you can find battery-powered and cord-powered models whether you prefer camping off-grid or at a campsite. These mini-units are lightweight, operate on 12V, and run quietly. Click here to see Zero Breeze portable AC on Amazon.
