• Max. pressure: 120 PSI
• Inflating speed: 1.47 CFM
• Continuous work time: 25 minutes

The Viair 88P is a popular 12V air compressor that is built like a tank. This is a model that has been designed to last because it has excellent built construction. It will also deliver a reliable inflation performance of 1.47 CFM because it has capable components in it.

In fact, you can use this compressor with tires of up to 33 inches, which is quite impressive considering its small size. It comes with a few accessories that will also allow you to inflate bicycle and motorcycle tires with ease.

This model is equipped with a power indicator that will show you if the compressor is running or not. This is quite important because you may easily not here this compressor working because it is so silent.

Connecting this compressor to your battery could be easier as it comes with alligator clamps. What we also like about this model is that you get a long air hose of 16 feet. This will provide you with a lot of maneuverability when inflating a tire.

But what we don’t like about this compressor is that it does not come with many accessories. Indeed, you get only 3 inflation tips with it. Also, the price is quite high.

However, this model is still one of the best heavy-duty 12V air compressors out there. It has excellent built construction, superior performance, and good inflating speed.

Pros:

• Excellent built construction. Durable and long-lasting
• Can be used for heavy-duty tire inflating
• Power indicator to show if the compressor is running
• Long air hose of 16 feet

Cons:

• You don’t get many accessories
• The price is a little bit high

If you have never operated a 12V air compressor before, then you will feel right at home with the EPAuto AT-010-2. This model is by far, one of the most beginner-friendly air compressors in this review.

At the top of this air compressor, we find an easy to read digital display. It can display 4 units which make it versatile. Additionally, it also has buttons that will allow you to choose the exact amount of pressure you want to inflate a tire with.

One of the best things about this model is that it has an automatic shut off functionality that will prevent over inflation. You don’t have to worry about this air compressor blowing up your tire.

And in case you have a specific color preference, you can purchase this model in no less than 4 different colors.

The only thing we didn’t like about this model is its weak maximum pressure of 100 PSI. This model is clearly not intended for heavy-duty use. Also, the inflation speed of 1.06 CFM is not the best out there, especially when compared to competing products in the same price range.

But despite those caveats, this unit is still one of the best 12V portable air compressors that you can get for the money.

Pros:

• Very beginner-friendly. Easy to use
• Easy to read digital LCD display
• Modern and aesthetically pleasing
• Possibility to purchase in 4 different colors

Cons:

• Weak maximum pressure of 100 PSI

Also, you get all accessories with this purchase, including a handy carry bag.

More impressively, the hose length is 30 feet which means that you have a lot of maneuverability with this compressor. However, the hose quality is average. But it still gets the job done, though.

• Superior inflating speed of 2.3 CFM
• Very high maximum pressure of 150 PSI

Many air compressor manufacturers try to make the most reliable model for the money. However, many tend to forget one crucial aspect, which is safety. The Viair 300P is the best of both worlds because it is both safe as well as powerful.

Indeed, this model has a superior inflating speed of 2.3 CFM at 0 PSI. It will inflate any type of tire, from a bicycle tire up to a truck tire with great ease and in record time. It can also sustain a higher maximum pressure of 150 PSI. Furthermore, it has excellent built construction with a tank made from metal.

And one of the best things about this model is that the battery clamps are equipped with a 40 A in-line fuse. This means that there is no chance that this compressor will get damaged from an overvoltage.

Added to the fact that this model is also one of the smallest 12V air compressors that money can buy. The only negative we have with this model is its price, which could have been a bit better.

• Max. pressure: 100 PSI
• Continuous work time: 30 minutes

The problem with most 12V air compressors is that you cannot use them for an extended period. They get hot quite fast and need a long cooldown before further use. This is not a problem with the Kensun EHRComp-A58B because this model has a superior continuous time of 30 minutes. Pretty impressive!

Under the hood, we find a powerful 120 W motor that can suck in a lot of air compression. This model has a maximum pressure of 100 PSI, which is not the best we have seen but still more than decent for casual use.

The built construction of this model is also very good. It is made from a thick ABS plastic shell that is durable and long-lasting. You have a very practical handle at the top that makes this unit very easy to carry.

And a right at the front, you will find an analog pressure display that will always show you the pressure of your tire. Because of its handle and lightweight, we safely nominate this model as one of the best handheld 12V air compressors on the market.

Also, despite its small size, it is still quite performing with an impressive inflating power of 2.12 CFM. It will have no problem inflating any type of tires relatively fast, from SUV to camper trailers. It can do it all.

Moreover, it’s a continuous work time of 10 minutes is quite good. This work time is not the best we have seen but considering its size this is forgivable.

But what we like the most about this model is its long 16 feet extension hose that makes it very maneuverable. You can easily inflate a tire several meters away from your vehicle with this long hose. The only disadvantage we see with this product is its price, which is a bit expensive.

How to Buy the Best 12V Air Compressor

Photo: EPAuto

Before finding the best 12V air compressors for the money, there are some important factors to consider.

1. Power

The 12V air compressor is equipped with a motor that sucks in air and compresses it. Of course, this process requires power.

A typical model will have a power of at least 100 W. With this type of electrical power; the motor is powerful enough to compress air as well as provide a decent air delivery to inflate large tires.

In addition to the wattage, also pay attention to the amperage. A motor that has a higher amperage is normally more powerful than a smaller one.

2. Max pressure

This is simply the maximum pressure that the various components in the 12V air compressor can withstand.

When it comes to this value, the higher, the better. However, you should go with a model that has at least 100 PSI maximum pressure.

This will guarantee that you get a compressor that has decent compression capabilities and will not make the motor work all the time.

3. Inflating speed

As its name suggests, this is simply how fast the 12V air compressor will inflate your tires. This value is measured in CFM or Cubic Feet per minute.

A usable 12V air compressor will normally have at least 1.0 CFM.

However, if you want to inflate tires fast all you need a model to inflate large tires like truck tires, then it is best to go with a model that has at least an inflation speed of 2.0 CFM.

However, keep in mind that generally, an air compressor that has a higher inflating speed will also be more expensive as well.

4. Continuous Work Time

Since the compressor is equipped with a motor that uses power to compress air, it is normal that it gets hot over time.

Therefore, they have a limited amount of time that it can be used continuously. Most top-rated 12V air compressors will normally have a continuous work time of at least 10 minutes.

After the continuous work time, you will have to wait for a cool-down period that is normally the same as the continuous work time, or more.

If you are planning to use this tool for an extended period, then it is always best to choose a model that has a high continuous work time. A model with at least 20 minutes work time is not hard to find at a reasonable price.

5. Cord Length

The 12V air compressor is connected to the battery for it to work. So, you are limited by the length of the battery cord.

For a pleasant experience using this device, we recommend that you go with a model that comes with a long battery cord.

In addition to the battery cord, you must also consider the air hose length. This is the hose that connects the compressor to the tire.

We recommend you choose a model that comes with a hose of at least 16 feet in length for flexibility when inflating.

6. Power Indicator

It is important to choose a 12V air compressor that is equipped with a power indicator.

Most models are dead silent, so a power indicator light will give you important information on the operation of the compressor.

Conclusion

In case of a tire emergency, nothing beats the 12V air compressor. You can simply connect it to your vehicle battery and will start inflating your flat tires with ease.

And in case you have never operated this tool before, then don’t worry. The 12V air compressor is extremely easy to use.
