What is pressure and inflation capacity?
A correctly pressurized tire stabilizes the structure of the tire and evenly distribute the support across the tread of the tire. This optimizes the performance of your tires, which ensures greater safety.
What is the air flow?
How is a portable air compressor used?
Once the pressure of the portable air compressor is programmed, you should now attach the nozzle to the air valve of the tire. Wait a moment for the device to stabilize and it will begin to inflate. Digital models automatically stop when they reach the marked pressure. Remove the nozzle, replace the cap on the valve and your portable air compressor is ready to store away again. It’s really that easy.
Here’s a step-by-step guide of how you should use a portable air compressor.
- Turn on the air compressor.
- Mark on the screen, using the buttons, the desired pressure of your tires.
- Remove the valve cap and be sure to leave it in a safe place.
- Apply the air compressor nozzle to the valve of the tire.
- Wait for the compressor to stabilize.
- The tire will inflate. If you are using an automatic compressor, it will stop when it reaches the marked pressure. If it does not feature auto-shutoff, pay close attention so that you do not overinflate the tire.
- If you have an overinflated tire, use the compressor to remove pressure until it reaches the value as indicated by the manufacturer.
- Once the tire is inflated, replace the valve cap and turn off the compressor.
When purchasing a portable air compressor you must take into account the way you intend to use it and the features it offers. There are many different models available on the market, which makes your choice a little tricky. To make the process easier, in this section we explain the most important criteria to consider. Continue reading and learn everything you need to know to chose the model that is perfect for you:
When choosing a portable air compressor you must check several specifications that will directly effect the performance of the device. One of the most important is the power rating of the model you are thinking about purchasing. Handheld and portable air compressors usually have fairly low power ratings somewhere between 1.5 and 5 hp. They are designed for domestic use, and certain professional applications.
Portable compressors are designed for tasks around the home, such as inflating toys or mattresses and for maintaining your car’s tires within the optimal pressure range. If you have a big car, with large tires, you should take a careful look at the power rating. Otherwise any compressor will work for standard tires, commonly found on cars, motorcycles or bicycles.
Not all air compressors are powered using the same method, since some can only be operated using a 12V car cigarette lighter socket. Other models have the option of being powered from a wall outlet. The models with the most functions and better performance offer both methods, and even have the extra option of an internal lithium battery.
For the majority of tasks, you will not require a pressure of more than 6 bars. Portable air compressors most commonly offer a pressure rating ranging from 2 to 6 bars. Although this may seem very low, this amount pressure is sufficient to inflate most tires, even those found on an SUV.
Although it is true that portable air compressors are the perfect tool to keep in the trunk of your car, so you can maintain the correct pressure of your tires, this is not the only way they can be used. Most models have nozzles and adapters that can be used for inflating sports balls, inflatable mattresses and all kinds of toys.
Some models of portable air compressors also include compressed air guns and blowers, which work perfectly for filling balloons or even to clean the keyboard of your computer.
Standing in the middle of the road at night to inflate a tire because you have a flat tire can be very dangerous. This is when the inflation rate of the compressor will be most noticeable, and when you will wish you had purchased a fast unit. The fastest portable air compressors on the market can fully inflate a tire in only 3 minutes.
More commonly, you will find that most models will take between 10-15 minutes to fully inflate a tire to a pressure of 35 PSI. So you can think about this when weighing up the price you want to pay, against the performance you are hoping to get. If your budget will allow you to buy a portable air compressor with a fast inflation speed, then you should definitely chose a model with this feature.
Size and Weight
Although all portable air compressors are usually fairly compact, before making your choice you should consider the wide-range of sizes in which these devices are available. Think carefully about how much space you have available to store it, and whether it will be kept in the trunk of your car, a closet or in your garage at home.
These gadgets are very small but extremely powerful. Most usually do not weigh in excess of 1 lb, although there are some models that weigh over 2 lbs. The smallest devices can be stored in the glove compartment of your car, although more commonly they are left in the trunk.

Finally pulled the trigger and upgraded to this @viaircorp 88p portable compressor as a bday gift to myself lol. My old POS compressor took a dump on me a couple months ago and I got tired of trying to find the nearest gas station just to air back up. This little compressor is a beast! It aired my tires from 24psi to 35psi in just a minute and a half each tire! Plus the hose is long enough to reach the rear tires without moving the compressor around the whole vehicle. ⬇️ ⬇️ ⬇️ #ford #fordexplorer #4×4 #liftedford #liftedexplorer #explorernation #explorermafia #explorergang #built_explorers #gofurther #builtfordtough #blueoval #rolaroofrack #hiliftjack #btffabrication #arbawning #lightbar #powertrax #trailchaser #offroad #fullindependentsuspension #overland #overlandexplorer #falkor #viair #portablecompressor #88p
What you want when you buy a device of this kind is for it lasts for as long as possible. This is why it is important when choosing which portable air compressor you are going to buy, that you think about how durable and resistant it is. This will depend largely on the materials used in its manufacture.
Portable air compressors are usually made of resistant plastics and have aluminum frames. This is because they are not supposed to be heavy. Although these materials are lightweight, they are very hard and resistant. Always be sure to check for warranty seals and compliance with manufacturing standards, to make sure you are buying a product that will last.
Most modern portable air compressors have an LCD screen, these are very easy to read and all the relevant data is clearly displayed. Models that have pressure gauges use a needle to indicate pressure, which can make getting an accurate reading a little more difficult. If possible, make sure you choose a model that has a backlit digital display.
Many of the latest portable air compressors also have built-in LED lights. This feature is great to have during an emergency at nighttime, because inflating a flat tire in the dark can be difficult as well as dangerous.
Reach and Light
Choose a portable air compressor with a hose that is at least 10 feet in length. In this way you can work easily on your car, without being limited by the size of the tire or the vehicle itself. If the hose is too short, your job will be much more complicated and very frustrating. If your car is particularly large, you may not even be able to reach all the tires.
When it comes to lighting, a compressor that incorporates a flashlight is an extra safety feature that you should definitely consider. Many models have powerful LED flashlights, perfect for use at night, while others have emergency mode with flashing red lights.
Portable air compressors are compact tools, that are the perfect companion for your next road trip. Maintaining the correct tire pressure is a basic maintenance task that your should regularly perform on your vehicle. These devices allow you to easily check the pressure and keep your car tires working at their optimal level, and with less wear and tear.
You can store the compressor in the trunk of your car, and some models are even small enough to fit in the glovebox.
