5. Puma Industries PD1006 Air Compressor12 Volt Air Compressor with Storage Tank 

There aren’t a lot of air compressors that boast quietness. The Puma Industries PD1006 Air Compressor is a whole lot more robust than other units of this size. When in operation it produces enough power to inflate a small truck’s tire in well-under two minutes. If you hook up a 10-gallon reserve tank to this compressor, it takes about six and a half minutes to shut off at approximately 130 psi. 

The pump will last for years with minimal maintenance given regular check-ups. The motor cooling fan prevents the motor from overheating. The price is quite reasonable in view of its numerous advantages. This is a stationary unit, designed mostly for on-board use.  The unit operates smoothly on uneven terrain and in very high or very low temperature. Excess water is removed from the air through the added water trap. If noise is your main concern and you need a big air compressor, this portable unit is just for you

Key Features

When going from 90 to 120 PSI the recovery time is only 50 seconds. From an empty to full tank you’re looking at 130 seconds. For safety, there is a thermal overload protector and two pressure control gauges so you can monitor the unit’s parameters when in operation. This is an ETL-certified compressor with a 1-year limited warranty. It has a 0.25-inch universal quick connector and you can expect an amp draw of only 7.6, so nothing that will break your circuit. Heat is managed very well by the overall design and dissipates more efficiently than in other models.

Buyer’s Guide

In this section, I am going to explain some key features you should be looking for when buying a 12-volt air compressor. If you are mostly pumping up your vehicle’s tires and your kid’s balls, then you don’t need to invest in a professional air compressor that will occupy precious space in your garage. A simple 12V DC compressor that plugs into your car’s cigarette lighter is more than enough to keep all of your stuff filled up with the right amount of air.

Types of Sockets

You can plug your compressor into a 120-volt socket or a 12-volt power outlet, as it is usually very adaptable. You can buy a model with a rechargeable battery if you are planning to use it for building off the grid. Some units plug into a cigarette socket, while others need a standard plug socket. It really depends on what you need to use it for. 

PSI

The PSI is very important to check before you buy an air compressor. Make sure that the air compressor’s PSI is compatible with that of the other tool you’re planning to use it with. If the other tool requires a very high PSI, you need to buy a compressor that can generate it. Therefore, it’s always important to check this before you buy an air compressor.

CFM

When you are looking to purchase an Air Compressor, the term CFM will certainly stand in your way. Simply put, CFM stands for Cubic Foot per Minute.  This refers to the amount of air that is being pushed down the hose and through the nozzle at anyone one time.

The bigger the value in front of the letters CFM, the more air is pushed through the compressor the more powerful the blast that it generates. If you need to power an air sander, you will need an air compressor of up to 10CFM and 100 to 120 PSI. If you need to use an air nailer, you will only need an air compressor with a CFM of between 2 and 5 that generates PSI of 70 to 90.

Duty Cycle

Compressor duty cycle refers to the amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %.

 As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

Auto Shut Off

Not all air compressors come with an auto shut off. It is a very useful function, as it automatically shuts off the unit once the desired pressure in the tire or in the tank has been reached.

Frequently Asked Questions 

In this section, I wish to highlight some of the most frequently asked questions about 12 volt air compressors. 

Mobile / Portable Vs Stationary?

This is the most common question we receive from people planning to buy an air compressor. This is one of the primary distinctions between different air compressors.  Stationary air compressors are obviously designed not to be moved. They are constructed so as to be a permanent fixture in the workshop.

All of them have very large air tanks and their motors tend to be much more powerful than that of their portable versions. Consequently, they are meant for professional use, they are more heavy-duty and their prices are much higher than that of the portable models.  Also, some of the larger stationary air compressors seem to have a much higher voltage.

Portable air compressors, on the other hand, vary in portability but they are all designed with handles, often integrated as part of a protective ‘roll’ cage, and some even have wheels, although the quality of the wheels themselves may vary.

They fit well in the tank of a car and they are more user-friendly and versatile. The best news is that they are also cheaper and much more common on the market.

True 12V & Higher Applications

In general, a 12-volt air compressor is still able to work with quite a lot of tools and is still very useful. Voltage is the actual pressure from the electrical circuit in the air compressor. This pressure then pushes the charged electrons through the wires in the air compressor. Therefore, if there were a higher voltage, then it means that there would be more energy that could be used from the exact same quantity of current.

Please note that cold weather can make your air compressor consume a lot more power. If your unit does tend to be rather slow, it’s best to leave the drain plug open, as this will help it start up easier.

How Much PSI Can a 12v Compressor Produce?

The model Viair 40047 Automatic Portable Air Compressor is one of the most efficient units in this regard, as its 12 volts of power directly translate to 150 PSI of working pressure – all of which comes from your car’s battery!

How to Repair a 12-volt Compressor?

This really depends on what is wrong with your compressor. If there is a major problem with it, then you should seek specialized help. There are some issues that may arise after you’ve used your air compressor that are fairly easy to repair. For example, you may need to adjust the airflow by turning the upper screw. If there is a problem turning the unit on, check if it is connected properly. If it is, use the RESET button at the back of the compressor.

The third issue that you may discover is that there may be a leak. To solve this, you will need to use a plumber’s tape and wrap it around where the leak is coming from.

What Should I use My 12v Compressor for? 

As one of the most portable types of air compressors, 12V units tend to be a bit less powerful than other types of air compressors. But you’ll still find a range in the power of 12V air compressors, with some units designed to deliver a serious punch, and others built only to inflate car tires.

All of the units reviewed above can inflate small to mid-sized car tires without any problems, but only some of these will do the job if you need to pump up larger tires. In general, you should care a bit more about airflow than max pressure, especially when looking for the best 12V tire inflator.

What’s The Best 12-Volt Air Compressor For Truck Tires?

Truck tires require some serious output and one of the units capable of delivering it is TIRE WELL 12V Heavy Duty Tire Inflator. This portable air compressor has a max PSI of 150 so it will be able to inflate your truck tires at a very quick pace. Given that it can inflate a car tire within just a couple of minutes, so it shouldn’t take much longer to inflate your truck tires as well. It has stability technology, so you shouldn’t worry about any vibrations that can make the unit move around while in operation.

12V Air Compressor Final Recommendation

There is a wide variety of air compressors available online. Alternatively, you can go to your local hardware shop or department store and ask for a quote and a brochure. Some models also come with a whole range of different features from LED lights to rechargeable batteries.

With the help of articles like this one you can make an informed choice and purchase the unit that you will make the best use of. Above I have covered the key features and notions related to the operation and exploitation of these devices. In any case, when you go to your local hardware shop, tell the assistant what exactly you are going to use the compressor for, and he will help you choose the most suitable model.
