Comparing The Best 12v Air Compressors Australia 2022

There are many things to consider when shopping for a 12v air compressor. Plenty of companies have started to pop up over the years, but there are only a few that really stand out from their competition.

Companies have taken advantage of this opportunity by creating products that are designed with the consumer in mind, not just at the initial purchase, but throughout the lifetime of usage as well.

Before making your final decision on the best 12v compressor for your rig, here are some things you should think about.

How Much Can Your Tyre Inflate?

The first thing you should consider, is how much can your tyre inflate? Most of the 12V compressors on the market today are designed for smaller tyres.

For example, if you have a tyre that is around 30 PSI, a small 12v air compressor will do a great job at inflating it to the optimal pressure of 35 PSI. The problem occurs when you have a larger 4×4 car tyre, such as one that needs 40+ PSI; it will take forever for the compressor to finish. Therefore you will need a 12v air compressor heavy duty.

What Type Of 12V Compressor Do You Need?

You also need to consider what type of compressor you need. Some people, they prefer a small, portable and more compact style due to the limited amount of space in their rig.

In this case, an air tank would not be very useful. But for others who have more room in their rig, then an air tank would be beneficial. This allows your 12V compressor to have its own separate space for storage, freeing up more usable space in your 4×4.

What Is The Accuracy Of The Compressors Pressure Gauge?

This can be very important, especially if you have a tyre that is around 45-50 PSI. If the compressor’s pressure gauge has a maximum of 50PSI, then it will probably not inflate your tyre to its optimal pressure unless you purchase a separate digital tyre inflator. It’s always best to check the accuracy of the pressure guage.

What About The Length Of Its Power Cord?

Another thing you need to consider is the length of its power cord. The longer it is, the more flexibility you have in terms of where you can use it if you chose a portable air compressor. However, most compressors don’t come with a very long power cord which means they are typically limited to being mounted.

How Many Accessories Are Included?

How many accessories are included in the kit may or may not be important to you. Some companies include a tyre pressure gauge with their compressor, some include an air hose, and some don’t include anything at all. Some companies include tyre mounting accessories which help with inflating your tyres more efficiently few will even include extra items such as tyre puncture kits.

Unfortunately, most 12v compressors on the market only come with a few different nozzles for inflation purposes.This can be a problem if you have a tyre that requires a special shape nozzle.

How Long Does It Take To Inflate A Tyre?

Let’s face it as quickly as possible is the correct answer for most. Nobody wants to spend more time than they have to on a dusty outback track in the heat waiting for their tyres to inflate.

For example, there are some 12v air compressors that come with an extremely fast flow of air which means they can inflate your tyre in less than 5 minutes. Spending a little extra on a compressor will give you a better flow rate. You do get what you pay for with air compressors as with most 4×4 gear.

How Long Can The Compressor Hold Power (Duty Cycle)?

The amount of time that your compressor can hold power during use is another important factor to consider before making any purchases. For example, many 12v compressors can cycle for 30 minutes or more while a few only have a max of 10-15 minutes.

Fortunately, most compressors can maintain stable air pressure up to 25-30 minutes before it needs to be refilled. These are just some of the many factors that you need to consider when buying one of these units for yourself.

What Is The Dispenser Range?

Some 12v compressors only allow you to maintain pressure up to 30 PSI in your tyre, which wouldn’t be sufficient for most 4wd’s. Fortunately, there are brands that offer a wider dispenser range up to 60 PSI or more.

Types of 12volt Air Compressors

12v air compressors come in two different stage types: single-stage and twin-stage. A single-stage compressor pressurises the air in one cycle, whereas a twin-stage takes two cycles to achieve full pressure.

The difference between these two types of compressors is what happens to the compressed air after it is produced.

Single-stage compressors are the most popular type because they are inexpensive and easy to maintain. Any moisture that enters the cylinder during compression will condense at high-pressure.

Twin-stage compressors pressurise the air twice, once in each stage. The first stage is a high compression where moisture may condense out of the air, and be drained from the system after it passes through a wet/dry filter. It then moves to the second stage compressor which compresses the dry air again and pressurises it. This process helps to eliminate any moisture from the air before it enters the tank so you don’t have to drain and dry out your system as often.

Twin-stage compressors are more expensive than single-stage compressors. However, they do a better job of keeping their tanks clean and free of moisture which provides better air quality.

What are the benefits of using a twin-stage compressor?

12v air compressors are powered by a 12v fitting (cigarette lighter fitting) in your car, so they need to be small and light enough to be transported easily. A 12v air compressor that is powered by a cigarette lighter accepts amps from 10 – 15amps for starting up. Whereas a twin-stage compressor will only use 5 – 7.5 amps.

Twin-stage compressors provide faster recovery times than single-stage compressors because they don’t allow any condensation to form in the tank. This makes it much faster for your compressor to recover its high pressure, which is necessary when you are using it as a tyre inflator.

What is the difference between three-stage and twin-stage?

A three-stage 12v air compressor is even better than a twin-stage because it is more efficient and provides cleaner air. A three-stage draws the same amount of amps from your lighter socket to power the compressor as it does with a twin-stage compressor.

The first stage of the three-stage 12v air compressor uses a standard piston cylinder. It pressurises the air just like a single-stage compressor by cycling the air through the cylinder.

When the compressed air gets to the second stage, there is a piston diaphragm installed with an oil cavity. The compressed air goes up to vents in this chamber, which charge it with oil droplets that are dissolved into the compressed air.

This oil charges your compressed air with lubrication that will prevent rust and corrosion, which is perfect for inflating tires. The third stage of the three-stage 12v air compressor uses a rotary screw compressor to pressurize the compressed air once more. This extra step ensures that your tire will be properly inflated with clean oil-charged air.

Are 3-stage compressors more efficient than single-stage or twin-stage?

3-stage compressors are more efficient because they recover the air to its original pressure in one cycle, while a single-stage compressor takes two cycles to achieve full pressure. This extra step ensures that your tyre will be properly inflated with clean oil-charged air.

12 Volt Portable Air Compressors

12v air compressors come with different accessories and nozzle tips, which are used for different applications like inflating tyres, air mattresses, pool toys etc.

Before you purchase, make sure to check if all parts are included, especially connectors. Most portable air compressor 12v have common attachment types, but some brands have unique attachments so be sure to double-check. Some come with heavy-duty clamps that allow you to attach the air hose without having to detach the connector from the tyre valve.

Some 12v air compressors have built-in digital pressure gauges, which allow you to monitor the pressure level of your tyres. Gauges that come with the compressor are almost always in the 20-50psi range which is perfect for inflating tyres. Make sure you have a standard tyre gauge in your 4×4 toolbox when needed.

12 Volt Hard Mounted Air Compressors 

When you hard mount an air compressor you’ll have to give some thought to where the compressor will be mounted. Plus, how it will be wired.

Most 4×4 owners have a set of drawers, a camping ridge, perhaps a cargo barrier and a 12v air compressor. Some air compressors are hard mounted along the side of 4wd in the quarter panel. The nozzle then connects to the outside of the drawer area where switches and USB ports are typically housed.

Once you choose a mounting spot you can then choose how your compressor will be wired. To the second battery in a dual batter stem or to the starter battery?

Most 4wd owners choose the starter battery as it is designed to have fast recovery rates and handle high outputs of power. It’s also a good idea to keep your 4wd engine running to ensure you don’t run the battery flat.

An Anderson Plug is commonly used to connect the power supply wiring of your 4×4 to the power supply wiring of the air compressor. An Anderson Plug will ensure a good electrical connection is maintained especially if there is a decent length of wire between the compressor and battery.


The size of your compressor is important whether you want a portable compressor or a hard-mounted compressor. Space is a premium in any rig due to the other 4×4 accessories, i.e. camping fridges, draw systems etc. Therefore a compressor that is compact is best.


Most 4wders are weight conscious about the many 4wd accessories for their rigs and 12v air compressors are no different. Weighing less is definitely best when considering any addition to your rig.


Apart from the quality of the compressor itself and its components, there are other quality issues for consideration.

What Is The Quality Of The Compressor’s Housing?

Another thing to consider is the quality of the housing unit itself. For example, some compressors have a plastic housing which can be fairly easy to damage and crack after repeated use. However, there are some companies that build their housing out of metal and provide a much higher quality unit.

What Is The Quality Of The Compressor’s Cords And Hoses?

Another thing you need to consider is the quality of its cords and hoses, which are usually included in the kit. If the hoses aren’t of a great standard and quality they can easily blow. Makes sense as there is high-pressure air travelling through them when you are inflating your tyres.

Fortunately, most brands offer an excellent warranty for their products which usually covers the power cord and air hose that is included in the kit.

Air Compressor Terminology Explained

12v air compressors descriptions will include numbers and acronyms such as PSI and CFM. Then there is duty cycles and other terminology that can be confusing.

Let’s take a look at what it all means. Then you can make an informed decision about which 12-volt air compressor is best suited to your needs.


The “PSI” in the 12v air compressor stands for “pounds per square inch,” and indicates how much pressure is being produced by the 12v compressor.

Generally, the bigger the PSI, the better. A compressor with higher PSI will be able to more easily inflate tyres. A 4×4 tyre usually requires around 35-40 PSI, depending on the load, i.e. towing a caravan.

*Note – Check with the tyre manufacturer or tyre supplier for the best PSI for your tyres

The size of the 12v air compressor is indicated by how many litres per minute it can inflate a tyre. If you’re going to be using a 12v air compressor, it’s a good idea to find out the maximum tyre size and PSI for your specific compressor.

Most common compressors have a max tyre size of 165/70R13. If you have higher-profile tyres or want to inflate car tyres, you will need a higher PSI.

Note! Always use a pressure regulator with a 12v air compressor to prevent damage or injury to yourself and your car tyres.

Pressure Regulator

A pressure regulator will keep you safe by preventing excess air from being pumped into your tyre and can be used with all 12v air compressors.

Look out for a built-in pressure release valve on the compressor that allows you to let off some of the excess air if needed. This is an important safety feature! The pressure gauge should read the correct pressure for your tyre.


The “CFM” in the 12v air compressor stands for “cubic feet per minute,” and indicates how much air is being moved by the 12v compressor.

Generally, the bigger the CFM, the better. It’s important to note that PSI affects tools directly — you’re able to use higher PSI power tools with a higher PSI 12v air compressor.

CFM is a bit different, as a powerful 12v air compressor will still be limited to around 20-30 CFM (depending on the tank size). This could mean that you won’t actually really notice a difference between two 12v compressors rated at 20 or 30CFM — it will depend on what type of 12v compressor you’re actually using.

Duty Cycle

The “duty cycle” of a 12v compressor is the amount of time it can be run before it needs to rest for an extended period of time.

This will vary depending on the type of 12v air compressor, however, generally speaking, lower duty cycles indicate that you’ll have less time to use the compressor before it needs to rest.

For example, a 30-minute duty cycle means that you can only use the 12v air compressor for half an hour before it will need 10 minutes of downtime. This could be a pain if you are on a hot dusty road in the middle of nowhere.

What does this all mean? When sizing up 12v air compressors, you’ll want to know about CFM, PSI and duty cycle. The size of the compressor will depend on what you’re using it for — but generally, more is better.
