What to Look for When Buying a 12v Air Compressor
It can be confusing scrolling through pages and pages of portable air compressors online or standing in the aisle comparing models at the home improvement store. Air compressors offer many different features, and at first glance, it’s hard to tell if one machine with fantastic features is better than the next one.
Trying to understand which features are essential for you is where this buyer’s guide comes in very handy. We’ve listed some important things to consider before spending your money on the best portable 12-volt air compressor for your needs.
Portable air compressors come with different power sockets. Some units plug directly into a cigarette lighter in your car (also known as the 12V auxiliary power outlet), others plug directly into a power outlet at home, and some can connect directly to your vehicle’s battery. Which power socket you choose depends upon how you plan to use your portable air compressor.
- Compressors that plug directly into the vehicle’s auxiliary outlet are very convenient for when you’re on the go. As long as your car is running, you can quickly inflate a tire.
- Ones with a wall plug work well when you’re running pneumatic tools or topping off the air in your tires before a road trip. Simply plug the compressor into a garage outlet, and you’re good to go.
- If you choose one that connects directly to your battery terminals, check the power draw before purchasing. Anything with a draw higher than 120 watts can damage your vehicle’s battery.
If possible, try to find a compressor with different power sockets. This will give you options depending on where you are and what power sources are available.
Maximum PSI Rating
Not only is the air output significant, but you also need to consider the maximum psi rating of an air compressor if you intend to use it to power tools. The psi, or pound-force per square inch, measures the air pressure generated inside the tank. To run pneumatic tools, including a basic nailer, you need a minimum of 90 psi.
It’s crucial that you match the maximum psi rating of the air compressor with the pressure required of the tool. If your pneumatic device requires a very high PSI and the air compressor has a lower rating, this will affect how the tool works. The compressor won’t provide enough pressure to let the device reach its full performance.
A smaller tank with a higher maximum psi is also beneficial as it allows it to function like a larger compressor. For instance, a 2-gallon compressor with 150 psi holds the equivalent of a 3-gallon model with 100 psi.
How quickly your 12-volt compressor works to inflate a tire is incredibly important, especially when you’ve broken down along the side of the highway. Getting you out of an emergency and back on the road quickly is a high priority.
Inflation speed, or flow rate, is measured in CFM (cubic feet per minute), a unit that describes how much air is flowing out of your compressor per minute. Most 12V air compressors should be able to inflate a standard car tire up to 30-40 psi in a few minutes. Higher capacity tires will take longer to inflate.
Since this guide compares 12V air compressors, it isn’t necessary to discuss voltage, but it’s essential to consider the compressor’s power capacity. The power capacity determines the compressor’s efficiency, and ultimately whether it’s useful or not.
Most models come with a power capacity between 2 and 10 horsepower (HP). To use the standard electrical outlets in your home, opt for something no higher than 2HP. Any larger than that requires a 220v to 240v outlet.
Maximum Continuous Working Time
This is the amount of time an air compressor runs before it begins to overheat and must be shut off to cool down. Cheaper models typically have a much shorter continuous working time and may not inflate tires with above-average psi ratings. If you’re looking to purchase a 12V air compressor for your RV or have larger truck tires, look for a compressor with a longer run time.
Digital or Analog Gauge
The air pressure gauge on a 12v air compressor is an essential control panel feature. It’s crucial that it’s easy to use so you can quickly check tire pressure. It also needs to be accurate to make sure you properly inflate your tire(s).
Pressure gauges on portable air compressors can either be an analog dial or a digital LCD. Both types have pros and cons.
- Digital displays give you an instant reading and can often be switched between units.
- Analog dials are typically more accurate, which some people consider better when using a 12-volt air compressor for tire inflation.
- Analog dials are easy to read when the sun is bright, but they’re unreadable at night unless they are backlit.
- LDC displays are hard to read in bright sunlight but easy to read at night.
Cord & Hose Length
Having a portable air compressor is excellent for convenience and portability. However, its function is considerably limited if the power cord or the air hose isn’t long. A short cord or hose is okay if you need to inflate flat car tires or you’re inflating pool toys. It isn’t helpful if you’re trying to reach the back tires on your RV or camper.
Before buying, think about how you’ll be using your air compressor and take a minute to study the cord or hose lengths. Ensure they are long enough for your needs, or look into purchasing a longer hose to extend your reach.
Auto Shut Off
Auto shut-off is a handy feature to have on an air compressor, especially if you’re new to using one. The auto shut-off automatically stops inflating an item when a designated pressure is reached, keeping you from over-inflating and causing damage. Unfortunately, this isn’t a feature available on all units, so you’ll need to watch out for it if it’s something you want.
On some air compressors, you can set the shut-off level yourself. On others, the air compressor gauges when to shut off, based on resistance met during inflation. This means if you’re not sure how much air a flat tire needs, it will automatically detect the amount. This way, you won’t over-inflate it and damage the tire.
Some models are also equipped with a thermal cut-out that shuts the compressor off when it reaches a specific temperature. This safety feature prevents overheating, extending the life of your compressor.
Size and Weight
While this feature isn’t as crucial as others, it’s still important to consider, especially if you keep your compressor in your vehicle or RV. Many compact models are convenient for storing in your car, but keep in mind they may not be as robust. The higher the performance rating, the larger and heavier the compressor. A larger compressor will take up more space – it will be more challenging to move around when needed.
Having an easy-to-use yet powerful, portable 12v air compressor on hand is essential if you do a lot of traveling in your vehicle or you often work with power tools around the house. They can quickly reinflate tires in the event of a breakdown and power pneumatic tools like nailers and impact wrenches. Like any similar purchase, it’s essential to understand the different features available and buy the best portable 12-volt air compressor for your needs.
