#5. Slime 40022 12-Volt Digital Tire Inflator

Slime 40022 12-Volt Digital Tire Inflator

If you are looking for a small 12v tire inflator with a digital gauge, then this model from Slime may be exactly what you are looking for. It’s compact and lightweight but don’t be fooled because it can still inflate a standard size car tire in less than 6 minutes. Best of all it simply plugs into your cigarette lighter or 12 volt power point in your vehicle.

This handy inflation tool is not only great at filling car tires but it can also be used for bike tires, motorcycle tires and just about any other inflatable item you can think of too. It can inflate any small tire that requires up to 35 PSI of air pressure. It boasts some great features such as an easy to read digital gauge, a bright LED light and an automatic shut off mechanism for when the desired PSI has been reached.

Keep in mind this is not a heavy duty air compressor and it is not sufficient to fill light or heavy duty truck tires. It will however easily fill most standard size car tires and it sets up in less than a minute and is ready to use. The biggest drawback with this portable tire inflator is the fact it can only fill tires that require 35 or less PSI.

#4. Raniaco 12V DC 150PSI

If you are looking for a good quality tire inflator that is very budget friendly then you should take a closer look at this model.

The biggest drawback with this item is that it has dial readout instead of having an easier to see digital readout. Given the fact that it’s powerful, budget friendly and easy to use we recommend anyone who is in the market for a new compressor to take a closer look at it.

This unit is really stable when working and does not jump around like some other small compressors for car do.

What Is Important When Selecting a 12v Air Compressor?

In order to find the best 12v air compressor for your needs, you will need to focus on several key characteristics of these handy devices. That is why we took the time to make up this informational 12v automatic digital air compressor buying guide.

If you focus your 12v portable air compressor for car tires purchasing on the following key features you stand a good chance of finding an electric tire pump that more than adequately meets your needs.

Here are the key features that the top-rated 12v inflator models usually have:

Easy plugin

One of the characteristics of 12 volt air tools that is supposed to be universal is their ease of setup. That means you want a car electric air compressor that easily fits into the cigarette lighter or 12 volt power point in your car. An air compressor that allows you to do this can be made ready to be up and running in no time at all.

Digital/Dial readout

Having a digital readout on your air compressor makes using it super convenient. These tend to allow you to preset your desired tire pressure and they often allow an automatic shutoff to kick in when that desired PSI is reached too. Dial type readouts are harder to use but the tradeoff is they are extremely accurate.

Adequate PSI

You need a device that can generate enough air pressure to fill decent sized tires. At a very minimum, any model that you buy should be able to handle standard car tires that require up to 35 PSI of pressure. A compressor that can generate up to 100 – 150 PSI is even better to have on hand.

Power cord length/Air hose length

There is nothing more frustrating than to not be able to easily reach the tires on your vehicle that you want to fill with your mini device. So make sure the power cord/air hose combination has enough reach to get to all the tires on your vehicle.

Common Problems with Tire Inflators

Even the best 12v air pump does not come without some drawbacks. Here are the most common problems you will encounter when using a portable electric air compressor:

  • Slow inflation rate

Even though some 12 volt models can handle filling tires as big as 150 PSI it will take a long time to accomplish this. The higher the PSI required for a tire the more time it will take to fill.

  • Blown fuses

Car electrical systems were not designed to handle the amp draw of portable 12v air compressors on a regular basis. Carry some spare 15 amp fuses with you because you will definitely blow them from time to time.
