This is an excellent choice for RVers because it delivers exceptional cooling power at an affordable price. One of the best features of this portable RV air conditioner is its adjustable fan speed and Sleep Mode. The Sleep Mode allows for air circulation in the RV without the loud humming that can disrupt a good night's sleep. This unit has three separate modes: cool, fan, and dehumidifier. You can choose to just run the fan on days where you don’t need dehumidifying or an AC - and this greatly reduces energy consumption. We love that this unit is powerful enough to cool down a decent-sized RV while also pulling moisture out of the air. And with a trusted name like Black & Decker, you know you’re getting a quality product. Finally, what might be one of the best features of this air conditioner is the fact that you don’t have to constantly empty the water compartment. This is because the unit comes with a hose adapter that installs on the back of the unit, allowing collected water to be drained out the window instead of accumulating in the unit itself. Overall, this is a highly recommended portable air conditioner for RVers looking for an affordable and effective way to cool their space. 2.

Tips for Finding the Best Portable AC Unit for Your RV One look at Amazon or literally any other marketplace and you’ll see dozens of portable air conditioner units… so how do you choose the best one for your RV? It’s not an easy choice and it’s not exactly an inexpensive appliance either… So here are a few pointers on selecting the best portable RV air conditioner. RV Size and Square Footage The first thing to think about when picking out a portable RV air conditioner is the size of the RV that you need to cool. If you get an AC unit that’s too small, it won’t be effective and you’ll end up hot and frustrated. On the other hand, you don’t need to spend money on the biggest unit if you have a small RV! Portable air conditioners are a popular choice for pop up camper air conditioning, and you don't need a huge one for such a small camper. In fact, in our list of the best ACs for pop up campers, it's all portable units. To find the square footage of the interior of your RV, you can get a rough estimate by multiplying the length of your RV by the width of your RV. Most RVs are either 8 ft or 10 ft wide. So an 8ft wide 30 ft long RV would be about 240 square feet. Try the equation with your RV to see how big your space is to find out what size AC you need. Venting There are ventless portable air conditioners, but if you want actual cooling or dehumidifying, you will need to get a vented AC. Vented portable RV air conditioners come with a big long hose that needs to be vented outside somehow, typically through a window. When looking at portable air conditioners for your RV, be sure to look at how they are vented and if they come with an installation kit. Many of the portable RV air conditioners on this list come with an easy installation kit that can be installed in any of your RV windows. Another thing you have to consider is which window you will use… not all RV windows will work, so this is a big factor! We used a portable air conditioner unit in our camper van and we vented it our the passenger cab window with a makeshift window cover. It wasn’t pretty, but it worked so well! Types of Portable Air Conditioners When you do your shopping you will come across two types of portable air conditioners: actual air conditioners and evaporative air coolers. If you want actual cooling and dehumidifying, you need an actual air conditioner. Air conditioners use refrigerants to cool the air and a dehumidifier to suck excess moisture and humidity out of the air. We all know that excess humidity makes it feel hotter than it really is, so a dehumidfying feature is essential. If you look online, you will come across several portable air conditioners and “personal air conditioners” that are much less expensive and claim to work just as well but be careful. Most, if not all of these are evaporative air coolers. They're also marketed as small portable air conditioners - and many can sit on a desktop. These devices work by blowing hot air over ice, water, or some type of wet cloth. These may provide cooling, but they don’t work in humid climates and they do not provide the same kind of cooling as an AC unit does. Plus, they add more humidity to the air. An evaporative cooler can cool air for a time, but they don't keep the air cool and they also don't dehumidify. How to Vent and Use a Portable Air Conditioner in Your RV A portable RV air conditioner is portable - which means you can take it anywhere… so the installation process isn’t very in-depth. All you need to get set up is a place to vent your new AC and a place to plug it in! Most portable air conditioners on this list come with installation kits - but not all of these kits will work with all RV windows. You may have to get creative with how and where you vent your portable RV air conditioner in order to keep the cool air inside. To install your portable AC vents, you will need access to an open RV window without a screen. To make it work efficiently and keep heat and bugs out, you will need to use a barrier to cover the rest of the open portion of the window. As we said before, many portable ACs come with some kind of window kit. You may be able to cut the installation kit to fit your RV, or you can use another method like cardboard, reflectix, etc. Here’s a helpful video on installing a portable AC in an RV. https://www.youtube.com/watch?v=3pQBYD57Z8w Beat the Heat with These Portable RV Air Conditioners Summer might be bearing down on you, but you don’t have to sweat it! Whether you want to get a portable RV air conditioner because your regular RV AC isn’t cooling properly or efficiently… Or if you just want to add one to a camper that doesn’t have one, all of these are great choices! Stay cool and happy camping :)
