What Is a Portable Air Compressor?


A portable air compressor is a type of air delivery device. Unlike the larger version, it usually does not have a tank but instead runs continuously to produce the air. Although, some models may have a small tank. They are lightweight and easy to carry and store. Manufacturers design them for small projects or specific uses.

For example, the purpose of the EPAuto 12V DC Portable Air Compressor Pump, Digital Tire Inflator by 100 PSI is to inflate tires and other similar items. These portable compressors typically are meant for use periodically and for shorter periods at a time.

Common Specifications to Note


There is a range of specifications a portable air compressor may have, and understanding them can allow you to better choose which compressor will work for your needs. A compressor for inflating tires is generally simple in design, so there are two main points to consider: power source and horsepower.

Power Source

You generally have two power options: AC and DC. Power Equipment Direct explains portable air compressors usually have DC power. This makes them capable of running on battery power. For an air compressor like the EPAuto 12V DC Portable Air Compressor Pump, Digital Tire Inflator by 100 PSI, this battery power comes from your vehicle. This allows you to hook the compressor to your vehicle through the DC connector in your car. A 12-volt option is generally sufficient for inflating tires.

Horsepower


Horsepower is the measure of the output of the compressor. You will see this listed as PSI. The higher this number is, the more power it has. However, you do not need extensive power to inflate a tire. The 100 PSI of the EPAuto 12V DC Portable Air Compressor Pump, Digital Tire Inflator by 100 PSI is probably sufficient for most vehicles.

How to Choose an Air Compressor

There are many considerations you need to make when choosing the right portable air compressor. Finding the right one is in the details. Some things the manufacturer may list in the products specifications. Others you may need to do some digging into customer reviews to discover. Regardless, the following are all points to keep in mind when you choose your portable air compressor.

Portability

PumpYourTires.com suggests always considering portability because this will have a huge effect on the overall usability of the unit. It should be easy to carry and should fit comfortably in your vehicle. You don't want a compressor that will take up too much room in your trunk, making it hard to carry other items. That isn't convenient, and any portable unit should be convenient. You should also consider weight along with size. You want to be able to carry it easily.

Speed

While portable air compressors usually work a little slower than their larger counterparts, they should still work efficiently and not leave you standing there waiting for a long time to add a little air to your tire. Keep in mind that inflation times differ depending on the size of the tire, so make sure you note tire sizes when looking over specifications.

Duty Cycle

The duty cycle is how much time the compressor can run before it needs to cool down. This is important because it kind of goes in hand with speed. If the compressor takes a while to fill your tire, you may have to stop during the process to allow the machine to cool down. Most compressors, such as the EPAuto 12V DC Portable Air Compressor Pump, Digital Tire Inflator by 100 PSI, will only be able to run so long before it starts to get too hot and needs a cool-down period.

Tire size

If you drive a car or other vehicle with small tires, then you can probably use just about any type of portable air compressor. However, if you have larger tires, you need to make sure the compressor you choose is capable of handling your tire size.

Controls

There are many options in controls on air compressors. The best ones will provide a digital readout, which is easier to read than the standard readouts. In addition, look for extra features, such as an auto shut off where you can program the PSI, and the device turns off once it reaches that set point.

Other Details

You also want to look at other details that will help to make the compressor easier to use. For example, always check the cord storage. Ideally, you want a cord wrap that will hold the cord when the unit is not in use. This helps keep it tidy but also prolongs the life of the cord. Another consideration is the accessories. This includes different nozzles, which allow the unit to be more versatile. If you have other nozzles, you could inflate, for example, pool toys or basketballs. Finally, you should always look into how loud it is when running.

How to Use a Portable Compressor to Inflate Tires


Using a portable air compressor is fairly easy. Before you start, make sure the unit is off. Each device may have different instructions, but in general, the steps are to first connect the valve on the unit to your tire valve stem. Make sure you do not lose the cap after you remove it from your tire valve. Then, you should plug the unit into the DC connector in your vehicle. Some vehicles may not power the connector unless your vehicle is on, so check to see if you have power and turn on your vehicle if needed.

Now, you can set the machine to the correct PSI and turn it on. Depending on the functions of the compressor, you may have to watch the gauge and turn it off when it reaches the correct PSI, or the unit will turn off on its own. Once complete, remove the valve, turn off the unit, and unplug it from the power.
