Things To Consider Before Purchasing The Best Tire Inflator With Gauge
If you have read through our top ten picks for the best portable tire inflator, you know that are a lot of features to be aware of. Without having sufficient knowledge about them, it is not possible to make a conscious purchase.
So, here we have listed all the characteristics of a good inflator;
## Digital or Analogue Pressure Gauge
When you are looking for an inflator with a gauge, the first thing you want to consider is whether you want to take a digital or analog one. Don’t hustle to the digital devices as the analogs boast some of its features that are way better than a digital inflator.
Analog inflators are heavy duty and will last for years. They have a good hose and generally very compact. They don't need any energy source, and their accessories are readily available in stores.
Digitals are much more accurate. You don’t have to worry about increments. They will also include necessary lights that will help you when working in the dark.
## Maximum Pressure
You will find inflators in the market that can range up to 250 PSI. But whether you need that much or not depends on you. An inflator with 0-100 PSI range is good. But you can also take 0-250.
The type and amount of electricity the device consumes is critical. See if the inflator uses AC or DC current or both. DC is essential for portability. It should work in around 12 volts in AC and around 110 volts in DC.
You also can get a cordless inflator. Those devices use batteries. Generally, AAA batteries are the best options. It should be an energy efficient device. For this purpose manufacturers generally include an auto shut off system. Time of automatic shutoff should be around 15 to 90 seconds.
## Hose Type
Be very careful about the hose type. They should be made with very strong materials as they will face the brunt of the pressure. General good quality materials are good quality rubber, braided steel or premium fibers.
You might not be giving the lights too much value but you will when you get into trouble in the dark. Backlit LED lights and built-in lights are very important. Inflators with light that has a good lumen power are preferable.
The more versatile the inflator, the better it is. Some inflators can't work with heavy vehicles like SUV or truck, and there are some which can't work with light objects like inflatable pools or balls.
Choose an inflator that can work with everything from construction vehicles to beach balls. For this flexibility, the inflator should come with all kinds of adaptors, nozzles and pin needles.
A portable inflator is a necessary tool for your car. Your inflator should be able to work with the cigarette outlet in your car. It should also have a compact design. The devices which come with a carrying bag are very convenient.
The length of the cord that plugs into your car is very important. It has to be around or more than 10 feet. The AC cord can be smaller but not less than 4 feet. Take a long one that can directly connect to your wall outlet.
## Preset Ability
It is a system that lets you set the exact amount of pressure you want in your tire. Then you turn on the inflator, and it compresses air into the tire until the tire has reached the desired PSI.
If you are going for a digital inflator, then you should look for this ability in your device.
The inflator gauge should have an accuracy of ±1 PSI. Anything more than that is not acceptable. You will find gauges with more accuracy extending to ±0.01 PSI. But anything in that range will do.
Inflators can come with a large variety of accessories. These accessories make them versatile and adaptable. The general accessories are valve core tool, valve caps, thread tape roll, ungraded brass air chuck. Some inflators come with a twist on air chuck and batteries. Needles and nozzles of many types also come with them.
## Body Protection
There should be sufficient body protection to ensure a long life for the device. The first line of defense is the built material. The stronger the material is the better protection the device has. Then there should also be padding. Generally, manufacturers add rubber padding to ensure more security.
A large display is always a big plus. Displays with good resolution are preferred. Try to find one with .1 psi. A backlight is very important for displays. You will be disabled if your tires blow out at night.
The above characteristics are for digital gauges. But analog inflators also hold a display mechanism of the pressure. Make sure that they are magnified and the glass is clear.
Analog inflators will only show you PSI taking in the fact that you are purchasing that in America. But electronic inflators can show you multiple parameters like BAR, KPA, KGF, etc.
If you don’t need that much, you can avoid it. But good inflators generally have this feature.
## Bleeder and Lever
There should be an air bleeder in your inflator. That helps to get the extra air out of your inflating object. You might also be able to do that manually.
The lever should also be easy to function. It should be able to inflate as well as deflate the tire.
## Air Chuck
This is one of the primary components of the inflator. As soon as you have your inflator check the air chuck for leaks. You can have auto lock on air chucks which are convenient to use. Other preferable products are NTP air chucks, dual air chucks, brass air chucks, and twisted air chucks.
Benefits of Having A Tire Inflator
Advantages of owning an inflator are not less. If you own something on wheels, you know the benefits already. Some of them are;
- Having the tire pressurized all the time without visiting the workshop.
- Understanding the exact measurement of pressure in your tires

These are some of the primary benefits. If you own a good one, there are gonna be a lot more. For the people who own vehicles, an inflator is a must have. It makes you a lot more independent.
How To Use A Portable Tire Inflator
This might seem like a funny segment of this article for the people who already know how to use an inflator. But our research tells us most of the people don’t know how to use a tire inflator correctly.
So here, we have tried to explain the best way to use them step by step. But you can develop your own after you have mastered the basics.
Step 1: Know Your Current Air Pressure
This is the first thing you wanna do. Check the pressure your tire currently has. This is how you are going to determine the needed pressure to reach your desired target.
Use your pressure gauge of the tire inflator for that. Press the air chuck into the air valve of the tire and then hold it like that. If the inflator has a lock on the chuck, then you can let go. Hold it until it has a reading on the chuck. When you have a reading, you can consider the first step completed.
While taking the reading make sure that the tire is cold. Hot tires don’t give accurate measurements.
Step 2: Determine The Amount of Pressure You Need
Generally, the amount of pressure your tire requires will be written on your doorjamb. But if your tire is not the original cars model, then you have to find out the correct amount of pressure. Generally, it is between 30 to 35 PSI.
Step 3: Locate And Prepare The Caps And Valves
To start the main process take off the caps of the valve stems. Don’t get these caps rolling around. Losing them can be a big hustle.
Step 4: Use The Inflator
Now, it is time to use the inflator. Lock the air chuck in place and start the compressor. And hold it in place until you have your desired pressure.
If you have a digital inflator with pre-set ability, then set the desired pressure that you need in the tire and turn on the inflator. The device will automatically fill the tire and stop when the desired pressure target has been reached. Keep monitoring the pressure while filling the tire up of you don’t have a preset feature.
When you are done with filling, don’t forget you put the caps back on.
Step 5: Intervals Of Checking Pressure
The general rule is that you should check the pressure of your tire every 30 days. If you are having issues with your tire, then check it every 10 degrees change in temperature or every time you refuel.
Tire Inflator vs. Air Compressor
There is not much difference between an inflator and an air compressor. Compressors range from huge industrial machines to small garage tools. They are generally not portable. They run on AC directly from the wall outlet.
Inflators are much smaller. They can run on both AC and DC. Some inflators even run on batteries. They are generally portable and compact. Most of them can’t be used with huge industrial trucks and construction vehicles.
Compressors are fast while inflators can take time to do their job. On the other hand, compressors consume a lot of electricity while inflators don’t.
Frequently Asked Questions
Q: How to check and adjust the pressure of tire?
A: To check the pressure of a tire you will need a gauge. Sticking a gauge or an inflator with a gauge in the tire valve will tell you the pressure reading. To increase the pressure turn on the inflator.
You can deflate the tire using the bleeder or deflating lever if they have those features. Otherwise, use your hand to loosen up the valve.
Q: How to use tire inflator with a gauge?
A: The process is the same as all other inflators, but here you have to wait a little bit after attaching the chuck to the valve to have the reading.
