Things we considered

Before you start looking and making your choice, it’s better to be knowledgeable about tyre inflators. Below are some of the features that we considered when looking at this unit.

Pressure gauge

This is one of the most important features in a good tyre inflator. It will show you the amount of pressure in the tyre as you proceed to inflate. Some units will have analog while others will have digital displays. Digital ones are more modern and preferred. Digital displays will also get back-lit making them readable in poor lighting conditions. Some more advanced ones will come equipped with a warning light to alert oncoming vehicles making them multipurpose.

Automated Settings

Manually inputting pressure settings in a tyre inflator can be time-consuming and cumbersome. Having an inflator with pre-set settings allows for ease of use and eliminates sometimes costly errors. The pump will also set itself off once you reach the optimum pressure level.


This is a very important feature that contributes to your final buying decision. Remember, you want the ability to inflate your tyres anywhere and anytime. You can get far away from any inflation services and experience tyre problems. A portable tyre inflator will save you all those problems. The weight of the unit you intend to buy will be a factor to consider. You want something you can easily lift and place anywhere.

Operation Time

Here, you have to consider both the inflation time and the duty cycle. Inflation time refers to how long the inflation process takes to fully inflate the tyre. You will then be able to assess the wait time for your car to get operational. That can save you from danger if in a bad area. The duty cycle refers to the time it takes for the equipment to cool down after usage. An inflator with over 50 percent duty cycle can work continuously without considering cool off times.

Tyre Size

When looking for a tyre inflator think about the size of the tyres you want to use it on. Some inflators will have the ability to inflate large tyres while others will not.

Power Source

How your inflator gets charged is an important factor to consider. Think of a situation where you’re far away from civilization and the inflator power goes low. It, therefore, becomes essential to select equipment
that will use your car’s charging system. The one that will get plugged into your car’s 12V port located on the dashboard. That means a lightweight inflator with the right plugging facilities. The ideal inflator should also have the functionality of using electric power.

“The pressure relief pump is an important feature. This inflator valve just flew out before one month was over. After unsuccessfully trying to screw it back, the user opted to apply glue to hold it.
