What is the best portable air compressor?
As the name says the portable air compressor or the tire inflator is a very compact and light-weight tool. It is not used for running pneumatic tools or inflating truck tires. It is great for re-inflating tires of your car or blowing up inflatable mattresses, kayaks, toys, etc. It is the portable compressor which can be powered by various sources, including a built-in rechargeable battery. Thus the above-mentioned features make it a versatile tool which everybody should have both at home and during traveling. The VIAIR 400P mostly suits the above-mentioned needs.
Why have I chosen this model? As the largest manufacturer of automobile and industrial compressors on the global market, VIAIR Corporation gives me this feeling of a total reliability and efficiency of their products, in particular their VIAIR 400P portable air compressor.
The Viair 400P is one of the fastest portable compressors on the market at a 33% duty cycle, that is, a continuous operation during 20 minutes. Although the tool requires cool-down after 20 minutes of usage, it is possible to complete the work before the need for a cool-down. It is capable to inflate the large tire in less than 5 minutes.
This device comes with a number of valuable features like the automatic shut off. This function will allow you saving money and time as it stops the unit as soon as it reaches the target preset pressure level. The 150 PSI rating will let you inflate even some of the largest tires and should have no problem handling your RV tires.
The attachments provided include an inline fuse holder, a 8 'power cable, a 25' air hose with 5-in-1 inflator / deflator functions, a 120 PSI gauge, a heavy duty sand tray with vibration isolators and a super convenient carry bag with storage compartments.

The reason you should think about getting a portable air compressor of you own
The modern lifestyle requires us to be active and mobile in order to catch up with its fast tempo. Luckily there are plenty of the advanced machines and devices that help us to keep pace with the time. A private car is a must for a man of today who fully relies on it. Unfortunately, we often do not foresee those unexpected surprises that can happen at the most inconvenient time. Flat tires or their deflation are the frequent occasions that, probably, each driver in the world had to face, at least once in the life.
I personally can share a sad experience with you. Once I had to stop my car in the middle of the road because of its strange behavior, due to the flat tire, as it appeared later. I couldn’t reach even the nearest service as driving with three wheels was not the best idea. Having realized that there was no tire inflator in my trunk, I had to stay in the middle of the road, crying for help and trying to stop any car. More than that, at the same time the heavy rain was falling on my poor head. So, as you can imagine, I wouldn’t wish the same happens to anybody!
Thus, having your own tire inflator allows you checking tire pressure and making sure they’re in an optimal range, whenever you want to do it. Incorrect tire pressure can lead to plenty of adverse effects on your driving experience. If you strive for increasing your tires life as long as possible and for saving you money in the long-term perspective, you have a good reason to invest in a tire inflator. In fact, it's a small investment with a high effect.
There’s a wide range of tire inflators and portable air compressors available on the market. They range from some smaller units that use your car's built-in 12-volt cigarette lighter, to powerful machines that need a standard power outlet. Most common 12-volt tire inflators won’t fill up your tires as fast as the air compressors. Nevertheless they’re more mobile, convenient and save your money as you can do this simple job by yourself.
Tire inflator or air compressor, what is the difference?
Frankly speaking, the portable tire inflators and air compressors do not differ considerably. Besides, their names are often used interchangeably by manufacturers. Some 12-volt units are offered as air compressors, on the contrary larger units of considerable overall dimensions are labeled as tire inflators.
If you want to use this tool as a tire inflator only or as a versatile powerful air compressor, you should primarily look at the features and specifications. It will help you to figure out the functionality of any particular model.
In particular, some small units, labeled as the air compressors are not designed to inflate trucks' tires. That is why, specify your needs first and only then proceed with search for your ideal tool.
Large air Compressors
They are available in a wide range and can be used for many household purposes. You can use some of them with light pneumatic tools such as nail guns, or for blow dust and dirt out of engines ’compartments, and filling up your tires as well.
Air compressors are bigger in size than small inflators. They need more power to deliver the desired level of pressure. Often air compressors need wall outlets but some lighter ones also run off the 12-volt cigarette port outlets in a car. Thus, they are less portable than the lighter tire inflators.
The biggest advantage of the air compressors is in their versatility in use. Besides, they can work with more efficiency in comparison with the smaller units and usually don’t have batteries to be recharged. Thus, you can use them selecting any power setting depending on the purpose of its application.
Tire inflators
Tire inflators or portable air compressors are designed to inflate the tires of the cars, as the name says. They are smaller in size and lighter than the large air compressors, with a more specialized functionality. The large compressors are equipped with numerous attachments onboard, so they do not fit to the dimensions of the car's trunk. Tire inflators are smaller that contributes significantly to their portability. Besides they come with additional features that simplify the process of their use.
These units are usually 12-volt and can run from the cigarette lighter in a car. Some models come with rechargeable batteries which allow you to be independent from any cords and power outlets. However this feature has its flipsides as the life of the battery which is not long-lasting and needs to be frequently recharged. It may take a longer time to provide an expected pressure level in comparison with their corded counterparts. Finally, it is not powerful enough to inflate high-pressured tires, truck tires, for instance.
In addition there are plenty of various functions and attachments that enhance the efficiency and user-friendliness of its usage.
So, it's up to you to decide which type and which model to choose. Herein I've prepared the list of the Top-7 best portable air compressors / tire inflators for cars within the price range from $ 40 to $ 200.

What features to be considered when buying a tire inflator for a car? | Buyer's Guide
Let’s figure out which features should be in the forefront of your considerations when buying a tire inflator for a car.
- Power source: Most of the inflators are still powered from the car's cigarette lighter. However, an AC adapter can be enclosed; otherwise you can buy it additionally. At the same time, there are many advanced tire inflators which are powered by rechargeable batteries.
- Auto cut-off: I guess it is one of the most important features. It enables tire inflation the desired PSI is reached with further immediate auto cut off. This feature allows using the tool with more safety due to elimination of a risk of over inflation or tire burst.
- Duty Cycle: It refers to the amount of time a compressor can be operated in a given time period at 100 PSI, and a standard ambient temperature of 72 ° F. It is expressed in percentage format:
Compressor on time ÷ (on time + off time) = Duty Cycle%.
For instance, 30% Duty Cycle means 18 Min. On / 42 Min. Off.
- Pressure gauge: This enables you to monitor the pressure level of your tires, so you can pump the latter up as soon as it is required.
- Lights: Some models come with built-in LED lights. They are useful for night time tire inflation. Besides, their warning lights will illuminate you and your car, as a sign of alert for other motorists.
- Price: The most simple tire inflators are capable to with car tires only. They will cost you around $ 20. More features like improved gauges, more efficient inflation process, and the ability to deliver higher pressure levels you will find in the units at a price of $ 30- $ 50 range.
More expensive inflators come with more advanced features and design, and can be used for larger tires like those on trucks. But they refer more to large air compressors.
Noise: Air tools can be really loud during operation. Nevertheless nowadays a wide range of the low-noise models are available on the market. Noise isolating components and lower decibel range contribute to reduction of the noise level. In general air compressors run at about 50-100 decibels. Thus, 50-80 decibel range deemed to be “quiet”.
Nozzle Attachments: The best tire inflator can be used for multiple purposes. A model that comes with several attachments will be very useful at home and on the road. Besides tire inflation they can be used for bicycle tires and sports equipment.
