Portable air compressors allow you to pump up your tires and power pneumatic tools wherever you are. Designed to work in your garage or workshop, you can easily use an air compressor with other pneumatic tools such as a spray gun for painting or your favorite nail gun.
With a simple flip of the switch, the portable air compressors with a motor and air storage tanks operate by creating air pressure using a piston and a chamber. The compressed air sits in the tank until you switch on the portable air compressor.
The compressed air then shoots into whatever air tools you are using, restoring low tire pressure for your bike, ATV, lawnmower, or car. The best thing about portable air compressors is that you can quickly move them to your task destination.
Because we know how daunting a task it is to choose the right products on the internet, we've taken the liberty to research and compile for you a list of the best portable air compressors. Let's look at some options you'll love.

Factors to Consider When Choosing the Best Portable Air Compressor
1. Air Pressure and Air Quality
Air pressure and quality are among the most critical factors to look out for when choosing the best option out of the portable air compressors listed above. You must ensure that you choose air compressors that deliver the air volume you need to your air tool at the right target pressure.
Let's look at an example. Say your tool needs 174 PSI to work well; this means that your air compressor must deliver air into it at 174 PSI. Therefore, you need to check the air compressors' settings to see which ones fit what you want to use them for. If you want home use, check the air compressors that can power the highest pressure tool you own.
When it comes to air quality, we're looking at the cleanliness of the air that your compressors or compressor is providing. The truth is that air compressors can produce air of various quality. You can have air that has dust particles, moisture, or even oil particles. Therefore, choosing a compressor that has good quality air is a must. Luckily, you don't have to worry, as the options above have moisture filters installed to ensure that you don't get contaminated air.
2. Free Air Delivery
We're referring to the volume of air your compressor produces. Free Air Delivery is measured in CFM and directly relates to your tool's air consumption requirement. Like we've mentioned above, you need to match your tool's air consumption with the Free Air Delivery of your compressor.
When using multiple tools, you need to add up the air consumption of all your tools and choose a compressor with a Free Air Delivery rating that meets the total.
3. Tank Size
What do you intend to use your air compressor on? The answer to this will determine what tank size you need. If you are using tools that require air pressure for a short time, you can get a compressor that has a small tank.
However, if you are using air tools that you will use for a more extended period, getting a compressor that has a bigger tank size is a good idea. Note that the bigger the tank, the less portable your air compressor.
4. Power Source
Most air compressors are powered by either gas or electricity. The compressors that run on electricity usually run on household voltage. The advantage of these types is that you can comfortably use them indoors as they don't emit any fumes.
Gas-powered air compressors are more convenient because you don't have to worry about how far you can go from the source of tripping over power cords. Also, they are often more powerful than their electrical counterparts.
However, they are not the best to be used indoors because they require well-ventilated areas.
Frequently Asked Questions (FAQs)
1. What Size Air Compressor Do I Need to Run Air Tools?
30 to 140 CFM
Most of the air compressors we've covered today fall within this range, and you can comfortably use them with your air tools. The options that have a lower CFM rating can be used for tires, sporting equipment, a car tire, a truck tire, or even car tires. However, if you want one for industrial applications, go for a higher CFM rating.
2. Can You Run an Impact Wrench with A Pancake Compressor?
You can operate an impact wrench with one of the excellent portable compressors we've mentioned above, although a small pancake compressor would work well for nail guns. This is because impact wrenches are intermittent tools. Therefore, unlike dir grinders or sandblasters, you will not be using an impact gun for an extended time.
3. Is a 6-gallon Air Compressor Enough?
Yes. Although this depends on the tools that you are using it on. Tools that need quick bursts of air, such as finish nail guns and pneumatic brad nail guns, drain your tank much slower. Therefore, getting an air compressor with 2-6 gallons is sufficient. Also, it's important to note that there are two types of pumps: single and two-stage.
You can also decide to take an oil-lubricated compressor or an oil-free one.
