The Best RV Air Compressors are powerful enough to fill the air in your commercial tires but compact enough to be tacked away. Why would you need an air compressor for your recreational vehicle? The biggest reason people buy air compressors when they own an RV is the fear of a flat tire when out on the road. Let’s look at the types of air compressors available and their functions. Here are the few we will review for you.
3 Best RV Air Compressors
The best overall RV air compressor and the one we would recommend is a portable one. What’s important about the best RV air compressor is things like the weight, PSI, size, CFM, and horsepower. It’s usually small and compact. Because portable air compressors are a huge part of the market, it is not as easy as it seems to pick the right one.
There are many different models with different features, sizes, and specifications. You have the very mobile pancake units and the larger with tank units that are both portables. For an overall recommendation, we looked at the following units.
It is lightweight with the longest air hose and highest CMF. It has a run time of 40 minutes and will fill the tires in under 5. RV owners will never have to worry about time running out before the tires are inflated. The typical RV tires of 30-35 inches fill in a very quick 5 minutes. It’s quiet and a lot of compressor for the price. It’s powerful. It’s durable. It’s lightweight. You can’t go wrong with this one.
2. Slime Elite Tire Inflator – Best Motorhome Air Compressor
In order to answer this one, you have to know the difference between a motorhome and an RV. In most people’s mind there is no difference and perhaps there is no substantial difference. The RV is a recreational vehicle and in the industry it usually is not the preferred term but it refers to the units like trailers and pop- up tents.
They can have some amenities that are like “home”. On the other hand, motorhomes were designed to be “homes”. They have separate rooms for the bathroom and bedroom and a casual kitchen. There are three classes of the motor home designated by the Federal Motor Carrier Safety Administration and the United States Department of Transportation. Size, purpose, and weight are the basis for the classification. The different classes have different size tires as well.
Class A: These are the largest and always considered a motorhome though most of us still call it an RV. They are usually luxurious with living rooms, kitchens, bedrooms and large bathrooms and perhaps a bunk sleeping area. Six to eight people fit comfortably on a regular basis.
These units are smaller than Class A and they tend to be taller to afford more space. They usually don’t have separate kitchen and dining areas. They have one bedroom and then sleeping spaces in the living room and the dining area. One bath with a stand-up shower. Usually only 2-4 people can be comfortable in it.
This is not usually considered a “motorhome” by most people, but it is by the government and for sales purposes. It is in between the Class B and Class A size-wise. It can have as many as 6 people sleeping comfortably. They are usually about 20 feet long with shower and bathroom, separate kitchen and at least one bedroom area over the cab.You also have campers and trailers that you pull with your own vehicle. The weight and PSI of the coaches are as follows.
Weight Tire PSI
You might want a larger air compressor for these motor homes, especially Class A and Class B. Some of these units are extremely larger and heavy. What’s needed for many of these motorhomes is a heavy-duty air compressor that can handle large tires in a quick and efficient manner. The air compressors we considered the best for motor home units are these.
Our choice here might surprise you, but we are going with the Slime Elite Heavy-Duty Time Inflator Generation 2. This powerful unit present with more CMF than any other and a comparable 100 PSI. It is perfect for motorhomes and heavy-duty trucks. Inflates quickly with any size tire and has a motor that is direct drive and features to prevent it from overheating.
It is lightweight and compact and will fit easily into your storage compartment. Finally, it has presets and auto-stop so you can just set it up and walk away. Its runtime is shorter than the others and its fill time is a couple minutes longer than the SuperGlow 12 V Heavy Duty, but its power and efficiency more than makeup for that.
3.Slime 40026 – Best Portable RV Air Compressor
All of these units for RVs are portable units. Some are in other categories as well. But overall, they are all portable. They are not necessarily compact, but they are portable. So what matters in a portable air compressor that is sufficient for a recreational vehicle?
Features that Matter Most in Portable RV Air Compressor
- Smaller tanks are preferred on an RV.
- Fill time
- Run time
- PST and CFM
- Length of hoses
You can see these are the factors we have used to compare all the air compressors for RV.s. Here are the most portable air compressors we like. Of these portable air compressors, we would choose the lightweight Slime 40026. It is not only lightweight it is heavy-duty as well and will be able to handle any size tires your RV might have. It conveniently plugs into your cigarette lighter and won’t take up much space in storage.
Best Compact Air Compressor For Rv
There’s not a lot of daylight between the best portable air compressor for an RV and the best compact one. In fact many people would consider them to be the same. However, you can have a portable air compressor on wheels with two tanks that take up a lot of space in storage. RV’ers don’t have a lot of space to give up and especially to an item they may use only once or twice on the trip. These compressors are “compact”.
They are not only lightweight they take up very little space as you will see. Many of them are what we call “pancake units”.

So who do we recommend in this compact air compressor category?
Surprisingly it is not a household brand. It is the Sunvook Portable Air Compressor Pump Digital Tire Inflator. Why? Because it is the smallest unit in size and weight yet packs the same if not better punch than the others.
It has 150 PSI in a 12 V unit that will fill your RV tires in about 5 minutes. None of the others can fill them in less than 8 minutes. In addition, this unit has some of the newer technology that we all want such as presets and auto shut off. So, you can go to dinner, take a walk, take a shower while your tires are inflated for you. It has a great digital display with a bright LED and a 12-month warranty with 100% money-back guarantee.
Rv Air Compressor Adapter
If you need an adapter there are many to choose from. Why would you need one? You would need one because your power cord might not fit the power source at the campground you pull into. You might be staying at a friend’s who has a generator you could plug into to inflate your tires.
This issue is you have a 50 amp power cord and the connection is a 20 amp. Or you have a 15 amp male and you need to connect it to a 30 amp female. Your air compressor will not come with a bunch of adapters so figure out what you need and purchase it before you hit the road. Here are just a couple that we would recommend you take a look at.
1. Aleko RV50-30-12 12” Adaptors Male 50 amp to Female 30 amp.
Copper is the material that this power cord is made from. It is resistant to corrosion and is waterproof. This dogbone adapter for the RV power cord is male to female and 50 amps to 30.
2. Kohree Dogbone Heavy Duty RV Power Cord Plug Adapter 15 amp to 30 amp and male to female with a twist lock.
If your RV has a 30 amp power inlet with a twist lock, and you need a 15 amp plug, this is one of the best. The lock is mechanism is a threaded ring. The adapter is 100% copper wire in polyvinyl heavy-duty plastic. Because of the twist-lock even if you accidentally drive away the adapter would stay connected and would not be lost.
