What is a Car Air Compressor
Modern technologies advance and facilitate our lives. When driving, many of us face troubles of deflating tires. Now, with the existence of car air compressors, you can say "Goodbye" to those troubles! A car air compressor is an electric device for pumping tires if they've got deflated or just need to be pumped after installation. Car air compressors are usually compact-sized and can be placed in car trunks. Car air compressors are divided into several types, and we will tell you about all of them in our review.
If you need to replace a tire on the road, we recommend you to read our review on car jacks.
What Features to Compare
First of all, you need to pay attention to the performance of a car air compressor as it determines its compatibility with specific vehicles. The car air compressors of 40 PSI are appropriate for tires of motorcycles or R13 tires of passenger cars. Such compressors are usually powered by cigarette lighters and come in handy when tires need inflation right on the road. More powerful car air compressors are suitable for tires of big vehicles as they boast higher pressure. So, the air compressors up to 100 PSI are generally used to inflate tires of minivans, pickups, and jeeps. The most powerful air compressors are used for trucks since their tires are capacious and need a lot of time to get inflated. Therefore, it is important to know the airflow rate of a car compressor (measured in l/min) as this parameter determines the time you need to wait till inflation is completed.
The design of an air compressor should be convenient for use. In particular, consider the length of power cord; it must be long enough to reach a source of power supply. The air hose should allow easy connection to the tire valve. Pay attention to rubber feet that absorb vibration and prevent moving of a compressor when it works. Lastly, check the type of a tire valve connector; it may be threaded or thumb-lock. Threaded connectors are reliable and durable, while thumb-lock models are more convenient and quick-detachable.
Usability and Features
Here we can mention an automatic shut-off function. This feature stops a compressor when the required tire pressure is reached, preventing the tire from overinflation and keeping a compressor safe. Car air compressors may be equipped with mechanical or electronic manometers that show the current pressure in tires during inflation. Electronic models have the edge over mechanical ones since they measure the pressure more precisely and feature a backlight. Some car air compressor may come with special nozzles for inflation of household items like balls, inflatable mattresses or boats.
Black & Decker ASI500
The built-in battery is the main advantage of this air compressor as it allows pumping tires without connection to power supply. The battery charge is enough to inflate 4 full-size car tires. This is very convenient since there's no mess with wires and the work is not limited by a power cord - the compressor can reach all the tires. Whether powered by electricity or battery, Black & Decker ASI500 produces the power sufficient to pump tires of virtually any vehicle. We also noted that thanks to its low-pressure setting, this compressor will be handy for inflating mattresses and rafts.
We would like to highlight the excellent functions this model provides. The automatic shut-off function is really useful and convenient since you can connect the compressor to a tire and do your chores while the tire gets inflated. The compressor will never feed too much air and will shut off automatically once the required pressure is reached. In such a way, the shut-off function will prevent tires from damage, saving your time and keeping the compressor safe. This is especially handy when you deal with capacious tires that need a lot of time to get pumped.

Q Industries MV50 SuperFlow
Powerful Does Not Mean Big
Q Industries MV50 SuperFlow is a highly powerful unit providing 120 PSI pressure. This is enough to inflate wheels of large trucks. The airflow rate of the compressor reaches 57 l/min, and this is a figure no other reviewed compressor can boast. According to our findings, this compressor inflates a truck tire in just 4 minutes and needs less than a minute to pump a car tire. Such performance really surprised us. Q Industries compressor should be connected directly to the battery of your car, so you don’t have to look for a power outlet to charge it. The compressor can’t be connected to a cigarette lighter since its amperage is too high for a car fuse. Note that the compressors of similar power are pretty heavy, but Q Industries MV50 SuperFlow weighs just 10.25 lbs. This is a bit more than most of portable models, but if you need a really powerful unit with medium weight, we recommend this air compressor.
The Best Driver's Assistant
We would like to point out that car air compressors have made the road trips easier and taken an important place at the service and repair stations. A deflated tire may bring you a lot of problems on the road, and Q Industries MV50 SuperFlow High-Volume 12-Volt Air Compressor is ready to solve them. A high power is an unquestionable advantage, yet this compressor provides an excellent usability as well. Pay attention to its air hose; it is 16 feet long and can reach every wheel without moving the unit. Moreover, the 8-ft power cord will let you use the compressor at a considerable distance from your car.

Viair 85P Portable Air Compressor
Quality + Reliability = Key to Success
We'd like to draw your attention to the way the Viair 85P is designed. The metal used for the compressor construction is really rigid and it will serve you hand and foot for many years. Despite the metal structure, the compressor is pretty light and weighs just 4.30 lbs. The air compressor is equipped with a plastic handle that doesn't get hot and allows for easy transportation even after the compressor has been long in use. In addition, the rubber feet of the Viair 85P absorb vibration of the engine and prevent the unit from displacement. The high-quality and dense sheath of the air hose will protect it from damages. The power cord features 15 Amp fuse that will prevent the wiring of your car from overloading. Finally, you can carry this compressor in a convenient bag that has a pocket for documents and nozzles.
Goes a Long Way
The usability features of this cigarette lighter air compressor are not limited only to the inflation of the tires. Thanks to the airflow rate of 51 l/min and the nozzles included in the package, the Viair 85P can pump inflatable mattresses, balls and even boats. Suchwise, the said compressor is able to inflate a tire with the dimensions of 31" x 10.5" at air pressure from 0 to 30 PSI within less than 5 minutes! This is the type of performance very few other models of car compressors are able to match.
A Few Facts and Helpful Hints
- The manufacturer's recommendation is often a good compromise. This compromise is reasonable and you should trust it in most cases.
- Even the slightest tire pressure change affects the fuel consumption.
- The more frequently the outdoor temperature changes, the more often you should check the tire pressure. Mind a spare tire! Check the pressure before starting the engine.
- If you are going to drive over rough roads, it may be useful to deflate tires a bit. But after that, don't forget to inflate tires back!
- The overinflated tires are common to grand tourers and trucks. Yet, if you overinflate the tires of your light vehicle, you can save on fuel, but it won't cover the cost of repairs.

Additionally, this air compressor features an auto shut-off function; the unit will stop inflation automatically when it reaches the target pressure you can set on the display. This feature might be helpful if you've forgotten to disconnect the compressor from a tire. The inflator will do the job and switch itself off, taking care of your safety.
The Greatest Tiny Masterpiece
JACO Premium Digital Tire Inflator is incredibly lightweight and compact. Thus, it can be placed in any place of your car, even in a glove compartment. So, from what we've seen, this air compressor copes with its job well and is able to inflate tires up to 100 PSI.
Did You Know?
Do you know that every tire loses 0.69 bars per month under normal conditions? Moreover, this number is higher when the weather is hot. Check the tire pressure at least once a month and pay attention to the tread. The recommended tire pressure is usually specified in the car manual or on tires. When the tire pressure is not right, the fuel consumption and braking distance can be increased. The overinflated tires adversely affect a suspension - a car bounces on road bumps and the suspension is the first to suffer.

Besides, the compressor doesn't lose its power when connected to a cigarette lighter as compared to the mains. We also concluded that this portable air compressor is an excellent assistant not just for car owners but for motorcyclists. What is more, the compressor is relatively cheap, being designed to inflate. And it does its job well!
Did You Know?
If a tire is pricked, the water can help! Still, you'll have to take some steps, too; you need to unscrew a core from a valve stem and pour a few glasses of water into the tire with a syringe or other means. Then, inflate the tire and go. The centrifugal force will "smash" water over the tire interior, and the water will block the hole of a tire, preventing the air escape. As water is a dense substance, it will leak out of the tire slowlier than air. In such a way, you'll get a couple of hours to reach a service station. Yet, keep in mind that this method is helpful when the tire is punctured but not torn.
The air pressure should be checked only in cold tires. The tires can be deemed cold if a car hasn't been used for at least 3 hours. Even after several miles of driving, tires get hot and their pressure rises by 30–40 kPa (4-6 PSI). No panic, that's not a fault. Don't reduce the pressure in warm tires. Otherwise, the wheels will be used with insufficient tire pressure.
