Tank Size Today’s portable air compressors for RV tires don’t often come with a tank. If you're considering an air compressor with a tank for your RV, make sure that it has enough capacity to fill at least one tire on your motorhome. 2. Power Supply Needs Most portable air compressors that you’ll find for your RV come with a few different power supply options. You should consider where you’ll be camping when selecting your air compressor. If you boondock often, you aren’t going to want an air compressor that only uses an AC 110/120V wall outlet for power. Look for compressors with connectors for your RV battery, rechargeable batteries, or a DC outlet plug. 3. PSI and CFM Ratings The PSI and CMF Ratings tell you how fast your air compressor will work and how much pressure the unit fills. For a faster fill, look for higher Cubic Feet per Minute (CFM) rating. If you need an air compressor that will fill larger motorcoach tires, look for an air compressor with a larger Pound per Square Inch (PSI) rating. 3. Duty Cycle The duty cycle refers to the time an air compressor takes to fill the tank. This value will only be found on air compressors that have tanks. If you select an air compressor with a larger tank, you’ll want the duty cycle to be higher, indicating that it'll fill the tank quicker. 5. Weight Don’t pick an air compressor that's so heavy; it's difficult to store in your RV. Smaller, portable air compressors for RV tires without a tank are easy to fit in your hardware bay and powerful enough to fill your tires. 6. Price If you're on a budget but still want to carry an air compressor for your RV tires, you may want to consider a portable, tankless option. These tend to be more affordable than those with a tank. Also, remember, you get what you pay for in the end. If the air compressor is inexpensive, there’s a good chance it won’t perform well or last long. 7. Noise Level https://www.youtube.com/watch?v=Dkbw6orBZjg Many air compressors come with a decibel value. This tells you the volume level of the motor. The lower the decibel number, the quieter the motor. Most portable air compressors don’t require hearing protection. Larger air compressors with tanks often have louder motors, making hearing PPE a must-have. 8. Hose Length You won't need a long hose if you select a cordless or battery-powered air compressor. But if your air compressor for RV tires has a tank and isn’t easy to move, you’ll want to ensure you have plenty of hose. A 10-foot hose won’t be convenient for filling up the tires on your 40-ft. Class A motorhome. Why Do I Need an Air Compressor in Your RV? Traveling with air compressors for your RV tires and other things is one of the best safety measures you can take. RV tires are intended to be filled to a particular pressure for safe driving and optimal fuel efficiency. If you're traveling and get a flat or low tire, an air compressor lets you fill the tire to the proper pressure without stopping at a gas station or calling a towing company. This can save you tons of travel time. Properly filled tires also reduce your potential for a tire blowout, which could cause an accident. What Type of Compressor Do I Need for Camping in My RV? Traditionally air compressors were a motor and pump attached to a tank. These aren’t terribly convenient for traveling. A portable air compressor can be a better option for RVs in most cases. Portable air compressors are small enough to store in an RV exterior bay and are light enough for everyone in your RV to manage. Also, portable air compressors can be used when you don’t have access to shore power. FAQs: What Can You Use an Air Compressor for While Camping? Can Your Air Compressor Inflate RV Tires? If you're buying an air compressor for your RV, you should ensure that it has enough power and capacity to fill your RV tires. If you're selecting an air compressor with a tank, ensure it has enough capacity. Before you buy a portable air compressor, check the PSI and CFM ratings to ensure that it'll be powerful enough to fill larger RV tires. Can You Use an Air Compressor for Pool Toys? We never leave home without a portable air compressor when we visit places where pool toys are necessary. Portable air compressors are perfect for inflating pool toys. Look for air compressors that have attachments for a variety of fill connections. Can an Air Compressor Inflate Your Air Mattress? We’ve not had good luck finding a connector that allows you to fill your air mattress with an air compressor. We’ve tried a few, and they don’t work great. While it's possible to fill your air mattress with an air compressor, it’s better to use a small pump that's made for inflating air mattresses. Can You Use an Air Compressor to Power a Nail Gun for RV Repairs? If you have invested in an air compressor with a tank, you can use it to power a nail gun for making RV repairs. You'll want to ensure that your air compressor hose has the proper connectors to work with your nail gun. Portable air compressors aren’t great for this kind of tool. They don’t have long enough run times and often don’t have the right pressure to operate tools like nail guns. What Size Air Compressor Will Inflate My RV Tires? When you're considering the right size air compressor for inflating your RV tires, you’ll want to consider three factors: horsepower, PSI, and CFM. Since RV tires are larger than standard tires, you’ll want an air compressor with high values for all three factors. However, the most important is PSI. Motorhome tires fill to higher pressures, so ensure that the PSI rating is high enough to properly fill the tires on your RV. How Do I Air Up My RV Tires? https://www.youtube.com/watch?v=Yzv3ymNZ5zQ Putting air in your RV tires is a pretty simple process. You’ll connect the air compressor to its power source and your tire. Then, turn on the air compressor and allow it to fill the tire. If your air compressor has a pressure gauge, fill until the gauge reads the right PSI for your tires. Use a handheld tire pressure gauge to track how full your tires are for air compressors that don't have pressure gauges. Can I Use an Air Compressor to Winterize My RV? Air compressors with tanks can be very helpful for getting your RV ready for winter. They can be used to clean off slideouts, drain water lines, and fill tires. If you don’t want to invest in an air compressor with a tank, you should consider a portable air compressor for filling your RV tires before storing it. This will help prevent dry rot, which weakens your RV tires and create a safety issue. How Long Will My Air Compressor Last? This really depends on how well you care for your air compressor for your RV tires. If you have a larger air compressor with a motor, pump, and tank, make sure that you follow the manufacturer’s maintenance recommendations. This will keep everything working for many years. Portable air compressors aren’t made to last like larger air compressors. So expect only to get a few years of use from them. You can extend the life of portable air compressors by not running them longer than necessary to fill a tire or two. Final Thoughts: What Is the Best RV Air Compressor on This List? The best RV air compressor on this list depends on your unique needs. Those stealth camping in a camper van may like the size and detachable battery of the AstroAI Cordless Tire Inflator. Yet Class A full-timers may benefit the most from one of the RV-specific VIAIR air compressors. The most important takeaway is that you should always travel with an air compressor for your RV tires for safety's sake. Having the right tool when you need it the most will give you that peace of mind as your cruise to your next destination.
