Best AC/DC Tire Inflators Buying Guide & FAQ
It’s no mystery that being able to inflate your car’s tires while on the road is a useful ability and that AC/DC tire inflators are a good way to go. But when it comes time to select one, the number of options can seem overwhelming. The good news is that it is fairly straightforward to find something that will work if you follow some key steps.
The first is to identify what tires you plan to inflate. This will dictate the amount of pressure you need from the system. Look at the flow rate and check that it comes with the attachments you need. Next, consider the length of the cords (both for wall outlets and the 12-volt adapter). They must be long enough to reach the rear tires.
With those criteria met, it largely comes down to user comfort. Are you more fluent in digital or analog technology? Do you want the inflator to have any special features or safeguards in place? The idea is to get as much benefit out of the inflator as possible, without draining your vehicle’s battery. So long as you find something compatible with your ride, you can get a lot of value out of an AC/DC tire inflator.
The Advantages of Owning an AC/DC Tire Inflator
There is no shortage of benefits to owning an AC/DC tire inflator, but the key advantage is the ability to keep your tires full wherever you go. Diminished air pressure is not always because of a leak. It can result from temperature and external pressure changes as well. With a tire inflator at your side, you are always better equipped to face any potential environmental issues.
Additionally, AC/DC tire inflators are designed for portability. The advantages of this feature are twofold. On the one hand, it is compact enough to fit in your vehicle without taking up much space. The unit should also be pretty lightweight. Plus, since it is built to draw power from multiple sources, it is also designed to move easily from the trunk to your garage. There are a plethora of other benefits, too.
- Prevents overfilling with pre-set controls on digital tire inflators.
- Adds convenience by letting you avoid gas station air compressors or AAA.
- Provides substantial air pressure from a small package.
- Portable tire inflators work in conjunction with jump starters to keep vehicles working in cold weather.
- Can draw power from multiple sources (wall outlets and 12-volt car adapters) for added versatility.
- Comes with lengthy power cords to make it easy to reach the rear vehicle tires.
- Fairly energy-efficient, meaning the inflator won’t drain your car battery.
Different Kinds of AC/DC Tire Inflators
AC/DC tire inflators all have a lot in common. Each one connects to both wall outlets and a 12-volt system. They are also all built for portability, with a compact air compressor. Of course, while all of these inflator systems share the essential features, there is still more than one type from which to choose. The key is finding the technology you’re most fluent in and going from there.
At one time, this type of tire inflator was the only kind around. It relies on a standard gauge to read the pressure. Usually, this will be highlighted in more than one metric to prevent issues with converting your readings. Analog systems are void of any digital features, often meaning they draw less power from the system. Typically, an analog tire inflator can generate as much pressure as any other type of system since this relies on the compressor itself.
Reducing the amount of power used is more than eco-conscious, it is a way to avoid draining your vehicle’s battery. Especially if the reduced pressure in your tires resulted from cold weather, this is an important feature. It also helps prevent overheating, since there is less strain on the circuitry overall.
Possibly the most popular type of AC/DC tire inflator, this type of system uses an LCD to showcase the pressure. Often, it will give you the option of changing the readout metric between KPA and PSI. Typically, the screen will be backlit and take up a small space either at the top or on the front of the inflator’s body.
Digital inflators often incorporate extra features, designed to optimize convenience. The preset function lets you tell the system how much pressure is needed. It inflates until it reaches that point and automatically shuts off. This reduces the chances of overheating. Often, digital systems are more precisely calibrated, letting you more accurately fill the tire.
AC/DC Tire Inflator Key Features
To get the full utility value out of your tire inflator, it needs to have all the essential features. Though some models have extras like built-in flashlights, there are some components necessary to its function as an inflator. Be sure that your AC/DC tire inflator meets your needs in terms of all these necessary features.
This is the component of the tire inflator that controls the air pressure into the tire. While a lot of compressors are massive, the technology used on an AC/DC tire inflator is far more compact. Because of this, you can tuck the inflator into your trunk and still have space leftover. It also facilitates a more lightweight design.
To work for your tires, there are two metrics to investigate. The first is the flow rate. Look at the liters per minute of air it supplies to get an idea of how quickly it will work. Next, look at the pounds per square inch it offers. Based on these numbers, you can determine whether the inflator will work for your tires.
To bring the air from the inflator to the tire, you need to connect the two. This is where the hose and attachments come into play. The hose is a relatively small tube that transmits the air from the machine into the tire. It needs to be capable of withstanding high pressure and hold its structure in cold and hot temperatures. The hose should also be short enough to not compromise efficiency.
The attachments are the parts that connect the hose directly to the valve on the tire. They are essential to making tight seals. Since not all tires have the same type of valve, it is important to check that the attachments fit with the wheels on your ride. That said, most tire inflators come with multiple attachments so they can be used on bikes, cars, and SUVs.
To be classed as an AC/DC tire inflator, the unit needs to work with two power sources. The first is through the wall socket, the alternating current aspect of AC/DC. Typically, this is the shorter power cord, since it is most often used in a garage where you are already close to an outlet.
The other power connection is the direct current part. The 12-volt tire inflator function connects directly to the outlet in your vehicle. This is the power source you are most likely to rely on in an emergency. The cord needs to be long enough to reach the rear tires on your vehicle with ease. Provided the power cord is long enough, you can rely on your vehicle’s battery to run the inflator.
To determine when your tire is at the proper pressure, you need a way to read its status. That’s where the pressure gauge comes in. Either an analog dial or a digital display will showcase the current pressure of your tires. With an analog system, you watch the dial to determine when to stop the flow. Most dials highlight the pressure in more than one metric.
Digital systems are a bit more advanced. They are often more finely calibrated and tell you the current pressure on an LCD. You can usually change metrics with push-button controls. Often, digital models come with a preset feature where you plug in the ideal pressure and the system automatically stops when the tire is full.
What to Look for When Buying AC/DC Tire Inflator
There are some key things to keep in mind when buying an AC/DC tire inflator, the most important of which is compatibility. It won’t do you any good to have a system designed for cars if your truck gets a flat. Take a look at the maximum pounds per square inch (psi) it supplies. This will let you know if the inflator is capable of filling the tires on your ride.
Once you know that it can work for your vehicle, the next thing to look at is the flow rate. The higher this metric, the more quickly your tire will reach the desired pressure. It should be able to fill a standard car tire in under five minutes, even if the tire had no pressure to start with. Provided the inflator meets these necessary criteria, you can move on to other considerations.
Look at the attachments on the system. Does it come with connections for the tires? Is the air hose long enough? Think about the power cords themselves. Will you be able to reach from the 12-volt adapter to your rear tire with the amount of wire it comes with? So long as all the sizes line up you can look to special features like a built-in LED flashlight.
