1. Viair 40047 400P-RV Automatic Portable Compressor Kit

Our first product, the Viair 400P-RV Automatic Portable Compressor Kit, is an incredible product made by a company that will be featured a lot on this list. With this particular Viair product, there are many things I love.

For instance, the 12-volt motor informs me this air compressor will have more than enough power to inflate my RV’s tires. In fact, this air compressor is often described as both incredibly powerful and efficient.

Additionally, the 150-PSI rating is a wondrous attribute for my particular needs. See, the tires I have a 100-PSI rating; therefore, this air compressor can inflate my tires to their peak condition without any hassle.

Moreover, the 40-minute run time is something that’s exceptionally beneficial. With this feature, I’ll never have to worry about the air compressor shutting off by itself before completely inflating my tires.

In fact, with the numerous reviews of this compressor filling up 30 to 35-inch tires in five minutes, I don’t think the runtime will ever be an issue. Due to this, you can see how practical this product is for an RV owner.

And its practicality continues to shine through when you consider it weighs only 19 pounds. Therefore, you can easily move this air compressor without straining yourself.

But there were some customer complaints about the instructions being a little unclear. Honestly, this fault is more of a nuisance than a detrimental issue.

With this issue being the only problem with this air compressor, you can bet it’s on the top of my list.

Pros
  • 12-volt motor
  • 150 PSI
  • 40 minute run time without shutting down
  • Numerous features to ensure tires get inflated quickly and efficiently
  • Weighs only 19 pounds

2.Viair 45053 450P-RV Automatic Portable Compressor Kit

The Viair 450P-RV Automatic Compressor Kit is another product from Viair on our list and just like its predecessor it doesn’t disappoint. Therefore, you shouldn’t be shocked that this air compressor sets itself apart from the rest.

For example, the 12-volt motor makes sure there’s no way this air compressor won’t have enough power to inflate your tires. You’ll never have to wonder about this air compressor’s capabilities with this motor: you know it’ll get the job done.

Just like the Viair 400P-RV, this compressor also has a 150 PSI rating, which, as mentioned before, is plenty for my particular needs. Never hurts to have an air compressor that has PSI rating well above your tire’s rating.

And with accessories such as an air hose, pressure switch, and inflation gauge/gun, you’ll never be unprepared for a tire inflation. Honestly, Viair might have gone a little overboard on the features, but it’s nothing I’m going to complain about.

Besides the incredible amount of features, this air compressor is light and ready to go at a moment’s notice with it only being 18 pounds. You’ll easily find a place for this relatively small and lightweight compressor.

Also, you can hook the air compressor up right to your RV’s battery with the provided alligator clamps. Again, this feature speaks to the practicality of this Viair air compressor.

In the end, there isn’t anything about this product that makes it inconvenient besides one annoying little thing. The trigger doesn’t have a lock button, so, you have to hold it done the whole time you’re filling up the tank.
Pros
  • 12-volt motor
  • 150 PSI
  • Portable and heavy-duty
  • Auto shut-off feature
  • Comes with an air hose, pressure switch, and inflation gauge and gun
Cons

3. Porter-Cable CMB15 150 PSI 1.5 Gallon Oil-Free Fully Shrouded Compressor

The Porter-Cable Oil-Free Fully Shrouded Compressor is a high-quality air compressor that will fit the needs of many RV owners. In being so, the first thing I noticed about this product is how incredibly sensible this air compressor is with its construction.

For example, the manufacturer made sure to incorporate a handle for easy transportation. With this feature, you never have to worry about overexerting yourself carrying this compressor around: you just pick it up by the handle and go.

In fact, this handle helps offset that this air compressor is a little heavier than some other products on this list at 20 pounds. But the handle’s inclusion helps negate this extra poundage.

And like the other two compressors mentioned above, it has a 150 PSI rating, which helps this compressor inflate tires at a quick and efficient rate. I mean, there’s nothing better than getting a product that does what you paid for it to do.

Furthermore, this compressor requires less maintenance than its competitors for the simple fact it has an oil-free pump. As someone who dislikes any cleanup, this feature is something that I love.

But even with all the things I love about this air compressor, there’s still one aspect that I find genuinely discouraging. There were numerous reports of this compressor being extremely loud.

Now, I don’t know how loud this compressor truly is, but the fact people keep bringing it up is not something you like to see out of a product.

Pros
  • Highly portable and has a handle that you can use to carry it with ease
  • Comes with an accessory kit with features and accessories that you can use for the inflation
  • The oil-free version of the pump means that it does not require too much maintenance
  • 150 PSI helps this compressor inflate tires quickly
Cons
  • Extremely loud

4. Porter-Cable C2002 Oil-Free UMC Pancake Compressor

The Porter-Cable Oil-Free UMC Pancake Compress is one of the top air compressors on the market for a variety of reasons. The first being its fantastic price. In comparison to other air compressors on this list, this product is a bargain.

Furthermore, this air compressor has a six-gallon tank that should handle the needs of any RV driver no matter the circumstances. For instance, a six-gallon tank will have more than enough air for my tires.

And the inclusion of this six-gallon tank doesn’t sacrifice the ability to transport this air compressor from place to place easily. See, it has a handle that allows for a person to move it around very quickly in case of an emergency.

In addition to being always ready to get the job done, this compressor is exceptionally well built. In fact, its excellent construction provides it with a sense of stability and toughness that is almost unmatched by its counterparts.

In other words, you’ll never have to worry about this air compressor breaking or having any malfunction. Honestly, Porter-Cable made sure this product was created to survive any situation that could arise.

But with this focus on durable, there’s a price to be paid. Unfortunately, this price comes in at 31 pounds. Now, 31 pounds isn’t outrageous, but if you happen to drop this air compressor on your foot, it can be quite painful.

Also, several reviews were complaining about the noise level emitting from this air compressor. Just like the other Porter-Cable product on this list, this cause of concern isn’t something I can overlook.

Pros
  • Amazing price
  • Large tank size
  • Easily transported
  • Perfect for home use and professional use in limited situations
  • Excellent construction
Cons
  • Very loud
  • Has a weight of 31 pounds

5. Viair 400P Automatic Portable Compressor

As you expect from Viair product, the Viair 400P Portable Compressor is a quick and efficient air compressor that fulfills the needs of most RV drivers with its high quality. At this point, you shouldn’t be shocked at the quality items coming from this company.

But for this particular air compressor, some attributes make it different from the others. For example, this air compressor comes with two 30-foot hose coils that I love.

See, with these hose coils, I can stay far away from the air compressor while it does its job. In other words, I won’t have to bear the awful noises that these types of machines emit as they fill your tires.

Moreover, it’s an oil-free design. In being so, this lack of oil means there’s no chance the air coming from the compressor will be infected with the oil residue left behind by air compressors that do use oil.

Additionally, the oil-free design makes this air compressor remarkably easy to clean. In other words, there’s no hassle of trying to get the oil residue out. As a human being who hates cleaning, this feature is something I love.

And even with these differences, it still features the obvious advantages found in other Viair products such as being lightweight (18 pounds), the automatic off-switch, and being relatively easy to use.

However, with the new features such as the oil-free design, there are some issues you need to be aware of before buying one of these air compressors. For example, the cooldown time is a lot longer than you’d like.

And in certain scenarios, you’d like to get up and go immediately. With this extended cooling off period, this sense of urgency becomes a little more difficult.

Also, the 2.3 CFM rating concerns me as well: it might be a long wait until your tires become inflated with a CFM rating like this one.

Pros
  • Quick and efficient
  • 18 pounds
  • Two 30-foot house coils
  • Oil-Free
  • Automatic off switch
Cons
  • Long cool off time
  • 2.3 CFM

6. Viair 300P Portable Compressor

As our last Viair product on the list, the Viair 300P Portable Compressor doesn’t fail to meet the standards left by the other Viair products within this article. In fact, this air compressor has some features that make it stand out from the others.

For instance, it’s incredibly lightweight, as it weighs about 12 pounds. Due to this, there shouldn’t be any worry on your part about having to move this around or storing this air compressor.

Moreover, this air compressor comes equipped with a 40-amp inline fuse, which allows it to handle multiple tasks without incident. As a person who values practicality above all else, this feature is a significant plus for me.

Further adding to this sense of practicality, this air compressor comes with heavy-duty battery clamps. These battery clamps can attach right to your RV battery and will not fall off until you detach them.

And this air compressor is proven to inflate 33-inch tires in a matter of minutes. As an RV owner, this feat shows me that this product can deliver the exact performance I need from an air compressor.

After all, if it can inflate a 33-inch tire, I don’t see why it would have any problem with mine. It’s just a comfort seeing numerous other people having success with the product you intend on buying. It gives you a sense that you’re buying something that actually will work.

But this sense of wonderment quickly fell to the wayside. See, it turns out the power cable is rather short at 8 feet. This length isn’t what I would be looking for in an air compressor as it severally limits your flexibility.
Pros
  • Heavy-duty battery clamps
  • Can inflate 33-inch tires
  • 40-amp inline fuse allows for the handling of numerous tasks without overtaxing the entire unit.
  • 12 pounds

In being so versatile, it gives you the option to decide which method fits you best. As a customer, I always look for products that offer you multiple ways of doing their job just in case one of the available options isn’t ideal for a specific circumstance.

Besides offering you multiple methods, this air compressor also has a 150 PSI rating to give you the sense that it’s ready to get the job done. Again, a rating this high gives me total comfort that this air compressor could effortlessly inflate my tires.

Also, this compressor is exceptionally lightweight coming in at 8 pounds. Honestly, an air compressor this easy to carry around would be a delight for any RV owner. After all, it’s just so sensible.

And all these features and convenience comes at a fantastic price. In fact, this product might be the best bargain on this list considering the price and all the amenities it offers.

But there are two glaring issues I have with this air compressor. First, the 2.12 CFM rating is a little lower than I would like. I need an air compressor that won’t have me waiting around for it to inflate my tires.

Additionally, there seems to be a consensus that this air compressor will not work on tires more massive than 40 pounds. Now, this issue isn’t a problem for me, but for others RV owners with larger tires this could take this air compressor out of consideration.

Pros
  • Fast inflation speed
  • Two ways to power
  • Quiet-working pump
  • Fantastic price
  • 8 pounds means easy portability
Cons
  • 2.12 CFM

Furthermore, it has a one-touch, push button that lets you have full control over the deflating or inflation of the air springs. For me, this addition offers me a sense of control because it gives an easy and effective way to control the process.

Also, it’s incredibly portability, as it weighs 8 pounds. Once again, I take the portability of an air compressor very seriously. I need an air compressor that can be move and transported with relative ease.

And Air Lift offers a 2-year warranty, which speaks to the confidence they have in this product. Honestly, anytime a company provides a warranty, it gets rid of my anxiety regarding buying that product.

However, I do have some serious concerns with this air compressor. The first being its price. Realistically, this air compressor’s cost isn’t even close to what I could afford. And I don’t think it’s worth the price, regardless.

Moreover, the 100 PSI rating is a little lower than I’d like to see in an air compressor. After all, an item this expensive should be able to compete in every area with its competitors. In the PSI area, it’s utterly lacking.

Pros
  • Has a high-quality gauge that tracks air pressure in great detail
  • Contains a one-touch, push-button control
  • 8 pounds
  • Two-year warranty
  • Versatile as it lets you make adjustments easily
Cons

Luckily, all these features come at a fantastic price and at a noise level that doesn’t hurt your ears. But some reviews continue to point out issues with the power. In other words, it takes a little while for this compressor to fill up your tires.

Also, there have been some issues with this compressor just not working with specific tires. I guess that’s why the price is so low.
Pros

  • Convenient with such as bright LED lights
  • 150 PSI

What to Look for When Buying an RV Air Compressor

RV Air Compressor Reviews

Before buying an RV air compressor, there are many factors you need to consider. Below, we’ll discuss some of these things to help give you a better idea of what you’re looking for in a high-quality RV air compressor.

Tank Size

Understanding what tank size you want is essential to getting the best RV air compressor for your circumstances. See, with these products, the tank size affects the overall performance of the air compressor.

For example, it indicates the maximum volume of air your air compressor can hold. Therefore, the bigger the tank, the more air it contains. But as the tanks get bigger, they get harder to transport.

And since you probably want to take the air compressor with you, you need one that’s easily moved. Due to this, you should search for an air compressor with a smaller tank but with a high PSI.

Pounds per Square Inch (PSI) and Cubic Feet per Minute (CFM)

PSI or pounds per square inch is a metric that measures air pressure. In this case of an air compressor, this rating will tell the amount of pressure it can fill your tires up to; there will also be a PSI rating for your tires, which you can find on the tire’s sidewall.

With this in mind, you’re going to want an air compressor that has a maximum output high enough to fill your RV’s tires. Therefore, getting an air compressor with a higher PSI rating than your tires is essential.

Along the same lines, The CFM or cubic feet per minute is the rating that tells you the airflow rate of the compressor. In other words, the higher the CFM, the faster your tire gets filled.

Both of these two metrics are usually presented together on air compressors. For example, let’s say your tire requires 75 PSI and you find an air compressor that has the following CFM and PSI ratings “5.0 CFM @ 90 PSI”. In this case, this air compressor would be a good purchase for your RV tires.

Hose and Power Cord Length

The best RV air compressors will have longer cords and hoses to allow you flexibility. In general, the hose length on air compressors varies significantly from 4 inches to about 30 feet.

Honestly, I couldn’t imagine getting an air compressor with a hose that’s only four inches long. But this is an outlier, as usually, an air compressor’s hose is around twenty to twenty-six feet long. I’d recommend getting a house around twenty-four to twenty-eight feet long.

Along the same lines, the length of the powers cords can have a massive impact on your experience with an air composer. So, make sure these cords are long enough to give you some wiggle room: around twelve to fifteen feet should suffice.

Noise Level

As you would expect, certain types of RV air compressors can be extremely loud. And since you’ll be in close vicinity to the air compressor, the noise level is something you must consider. Therefore, it necessary you know the exact amount of decibels each air compressor you’re considering emits.

In today’s market, the average amount of noise emitted from an RV air compressor is between 40 and 90 decibels. If it were I looking for one of these products, I’d want an air compressor that emitted noise at a level of 65 or lower decibels.

To put a 65-decibel noise level into perspective, it would be like a what vacuum cleaner or hair dryer could produce. Not ideal, but something I could tolerate.

Weight

One aspect buyers tend to underestimate is the weight of the air compressor. Please don’t be one of these people. You’re going to need an air compressor that you can move around and store easily.

After all, some people will see the word portable and think it immediately means you can pack it into your RV and go. Then, they get the air compressor in the mail and its over 40 pounds.

Therefore, it’s paramount you research the exact weight of each air compressor you’re considering. I’d recommend an air compressor in the ten to fifteen pound range for easy portability.

Frequently Asked Questions (FAQs)

RV Air Compressors FAQs

In the following section, we’ll try to answer any remaining question you have about RV air compressors. We’ll do our best to cover all the bases.

Why do you need an RV air compressor?

You need an RV air compressor for a vital but straightforward reason: you don’t want your trip ruined by a flat tire. Due to this, getting an RV air compressor could solve all your problems and make sure your tires are inflated to their proper level.

After all, under inflation/over inflation can cause a heap of problems and with the right air compressor, none of these issues would ever have the chance to ruin your vacation. In the end, getting one of these products is just a practical, logical investment.

What size air compressor do I need to inflate RV tires?

Well, it depends on how you want to use the air compressor. For instance, if you’re going to transport the air compressor around with on the tire, I recommend investing in an air compressor with a small tank.

See, the larger tanks can be tough to transport around: they can be quite heavy. And since you’re going to want the air compressor in your RV in the event something goes wrong, it doesn’t make sense to lug around a larger tank.

However, if you get an air compressor with a small tank, it’s essential that it has high PSI. In doing so, you’re ensuring that you won’t have to wait around for hours as your tires get inflated.

Which one is the best? (Viair 400P-RV and 450P-RV, Viair 400P vs 400P-RV)

Personally, I will pick the Viair 400P-RV. But I think you should check Viair 400P vs 450P RV.

How to maintain and check RV tire pressure?

The easiest way to maintain your tire pressure is by checking it every time you take your RV out on the road. And this doesn’t just mean looking at the bulge of the tire or hitting it with a trucker bat.

You need to buy a tire pressure gauge such as this one and use it to find your tire’s true pressure level. And with this product, it even tells you the tire’s temperature further protecting you against tire blowout.

After all, a tiny difference in PSI can make a significant impact on the weight amount your tires can responsibly carry. For instance, if your tires are 10PSI less than the recommended pressure level, it reduces maximum weight by 25%.

So, before every trip, check your tires with tires with gauge. It’s in your best interest.

Conclusion

Now, that you know all about the best RV air compressor on the market, it’s time you go out and get yourself one. There’s no reason your trip has to suffer because your tires weren’t inflated to the proper level with the existence of products like these.
