Portable Motorcycle Tire Inflator Buying Guide

When setting out to purchase a portable tire inflator for your motorcycle, there are several things you should look for to ensure you are getting a high-quality product.

To help ensure you get the best product for your needs and preferences, below we will outline some of these features and functions.

Duty Cycle

Like with any air compressor, a portable tire inflator will have a given “duty cycle.”

The duty cycle of a compressor is the amount of time that it can be used without becoming overheated during a particular time frame.

For example, a portable tire inflator with a duty cycle of 50 percent means it can be run continuously for 30 minutes, after which the motor must rest for 30 minutes to cool down.

Because portable tire inflators usually only have to be run for a short period of time—the time it takes to fill both tires at most—you can usually get away with a lower duty cycle, somewhere in the range of 30 percent to 40 percent.

Auto-Shutoff

An auto-shutoff function is very important in a quality portable tire inflator.

This unique function enables the unit to automatically switch off when the pressure reaches a pre-set level that you set, and allows it to automatically turn back on once the pressure goes below a certain level.

This prevents you from having to constantly look at the gauge to ensure the pressure does not get too high.

It also saves wear and tear on the motor, and keeps your hands free for other tasks.

In addition, to making the portable compressor easier to use, this convenient function also plays a very important role in preventing over-inflation – a common issue faced by most portable tire inflators that are not equipped with this function.

Lights

Nothing is worse than getting a flat tire on a dark unlit road.

Working in these conditions can be all but impossible, but with a portable compressor that has built-in lighting you’ll be able to see exactly what you are doing.

LED lighting on a portable tire inflator not only illuminates your work area, allowing you to see the valve stem and the pressure gauge, it also acts as an emergency light to alert other drivers that you are there, making any spot that much safer and secure.

Digital Gauge

A digital gauge is a great feature to have on your next portable tire inflator.

When trying to fill a tire out on the open road, the last thing you want to do is stop every so often so you can check the pressure.

Fortunately, with a digital, LCD tire gauge you will never have to do this.

This feature allows you to monitor the progress of inflation as you go, and stop the pressure once the gauge reaches the proper PSI for your tire, giving you the most accurate inflation possible thanks to this easy-to-read feature.

Inflating Speed

When you are stuck on the road with a flat tire, nothing will seem more important than a compressor with a rapid inflating speed.

The inflating speeds of various portable tire inflators will vary from model to model.

One with a rapid inflating speed is one that can typically fully inflate a tire in just a matter of a minute or more.

Some of the fastest motorcycle tire inflators can completely air both tires in about 2 minutes or less.

Because speed is so important, it’s imperative that you read as many reviews as possible with regard to this topic before making a final purchasing decision.

Size/Portability

If you are going to be carrying your portable air compressor on your bike, you are definitely going to want one that is very compact in nature.

Smaller does not always mean less powerful when it comes to an inflator, so be sure to get one that fits conveniently in your under-seat storage compartment without taking up too much room—room you may need for other tools and gear.

Noise Level

Air compressors of any kind are going to put out noise.

Large air compressors used in places like mechanic’s garages can put out about 90 to 100 decibels of noise, but the smaller air compressors/portable tire inflators are typically much quieter.

However, some portable compressors tend to be noisier than others.

For that reason, it’s important to look around for the compressor that puts out the least amount of noise, usually somewhere in the range of 40 to 50 decibels.

Multiple Uses

When shopping for your next portable tire inflator, you should definitely find one that can inflate more than just motorcycle tires.

Many of the best mobile inflators in the market come with different nozzles and attachments that allow them to fill almost any type of tire with various sized valve stems, as well as things like balls and toys that require inflation.

Warranty

Finally, portable tire inflators, or portable air compressors, are driven by a motor, and anything you buy with a motor should have a pretty decent warranty just in case of defects in the motor, electrical system, etc.

A longer warranty, say 3 to 5 years, is usually a good sign that the manufacturer has confidence in their product, while a shorter warranty, 1-2 years, may be an indication that you should take a pass on that particular compressor.
