1.EPAuto 12V DC Portable Air Compressor Pump – Cheapest Option
Our number one pick is the EPAuto 12v DC Portable Air Compressor Pump. This device is a plug-in portable air compressor that we find is perfect for car tires.
Not only does it run relatively quiet, but it also offers convenience with an automatic shut-off that activates when it reaches the pressure you need.
This compressor also features four easy to read displays that show psi, kpa (Kilopascal), bar, and kg/cm (kg force x centimetre distance).
It has a compact and lightweight design weighing less than 4 pounds and taking up less space than most of our other recommendations. It also has a 9ft cord with a 2.5ft filler and is affordable for the work it can do.
We wish that it had a quick-connect valve connector rather than a screw-in. We also noticed that it isn’t ideal for inflating truck tires and the unit doesn’t seem to fit very well in the accompanying carry bag. You can purchase the EPAuto 12v DC Portable Air Compressor for less than $100.
- Quiet operation
- Automatic shut-off
- Compact and lightweight design
- Screw-in Valve Connector
- Not ideal for truck tires
- The carry bag isn’t very useful
The VIAIR 85P Portable Air Compressor joins our list at number four. This plug-In compressor is a great mid-range option for most common household needs. Motorcyclists will enjoy this unit since it offers fast inflation times when used as an air compressor for motorcycles.
The compact design is also the lightest weight on our list and boasts a maximum working pressure of 60psi. We enjoy the built-in heat sink that keeps the unit from running too hot. It also has a 10ft power cord, a 3ft air hose, and an LED work light as great extras.
The problems we noticed include how the LED light is not very strong. The pressure gauge readings are not always correct. Also, the unit is more for filling tires and isn’t very good at handling flats.
What We Like
- Compact and lightweight design
- Built-in heat sink
- Fast inflation times
What We Didn’t Like
- The LED light is weak
- Pressure gauge readings are sometimes off
- Not ideal for flat tires
3.Viair 00088 88P Portable Air Compressor – Best Small Portable Air Compressor

All too often, the small compressors with the cigarette lighter plugs just can’t get the job done. The Viair 00088 88P compact portable air compressor is small and lightweight. Don’t let its size fool you.
This is no discount store cigarette lighter plug air compressor. The little machine packs features and performance that some bigger air compressors are hard-pressed to meet. Viair doesn’t skimp n features, even on its smallest and lightest portable air compressors.

The Problem with Heat
Compressing air creates heat. In a small compressor, the heat can cause problems. Most small compressors don’t have the means to dissipate that heat fast enough to provide long duty cycles.
Large air compressors can incorporate lots of cooling fin area and fans to drive air across the top of the air pump cylinder. Small compressors lack these features. In the case of the Viair 88P portable air compressor, the cylinder head has generous colling fins and the aluminium alloy is capable of quickly dissipating heat.
This alloys a longer duty cycle than most comparable ultra-small air compressors. The Viair offers a duty-cycle of 25 minutes. With the capability of filling a 225/60R18 tires to 30psi in a minute, you will never have problems with heat or duty cycle when you carry the Viair 88P in your vehicle.

From emergency air compressors for your personal vehicle to hard-mounted air compressors for RV’s and commercial vehicles, Viair can supply them all. Viair even has a specialized set of compressors for the custom car industry made specifically to supply air suspension systems.
The Viair line of 12-volt portable air compressors is some of the best on the market. When shopping for a portable emergency air compressor, there are several features that you should expect.
You certainly don’t want to be stuck with a flat or low tire in a remote location or far from the nearest auto shop with a q12-volt air compressor that won’t run or won’t develop enough pressure to properly re-inflate your time.
Many inexpensive 12-volt air compressors may eventually inflate your tire, but it may take an hour or more because they just can’t deliver the airflow at the required pressures.
Duty Cycle is the percentage of time a tool should be run between off times. For example, a tool rated with a 60% duty cycle could only be run for 36 minutes each hour and would need to be turned off for the other 24 minutes.
- Thermal overload protector
- Diamond Plate Sand Tray
- Quick connection air hose with heat shield
- Professional style large truck tire inflator
- Dual compartment carry bag

- Maximum working pressure 150psi
- Weighs only 13.05 lbs.
- Power cord length of 8ft.
- Hose length is 30ft.
One downside to most 12-volt compressors is the need to start and stop the compressor manually when changing tires or checking air pressure during inflation.
The Viair 45043 comes with an automatic function that turns the air compressor off if you are not actively filling a tire with air. This saves wear and tear on the air compressor and makes filling multiple tires more convenient.
What Are Mini Air Compressors
Mini Air compressors are handy devices to have around the house. Many compressors are built for job sites and construction work but portable mini air compressors are designed for everyday use.
Compressor-powered airbrushes make painting fences easier. Compressors are perfect for inflating tires, toys, and balls. Let’s not forget the many air tool options that DIY enthusiasts could use to speed up work with less stress and strain.
For all these reasons and more, it’s important to choose the right air compressor. But how do you know which compressor is right for you?
What Mini Air Compressors Are Good For?
When you are online at Amazon, eBay, or any other retailer looking for a mini air compressor 12v unit, you have a specific tool or purpose in mind.
Many retailers will tell you that you should buy a compressor because it can handle heavier-duty jobs, but savvy shoppers will avoid buying more than they actually need, especially for in-home use.
If you want an air compressor to keep balls, inflatables, or toys inflated and pressurized, you’ll have different needs than a user who has work or hobbies that need air tools.
As you’ll see when you see our top five list below, some mini air compressors are cheap and affordable because they are only for limited or emergency use.
Generally speaking, here are a few common household reasons for owning a mini air compressor.
- You have in-home hobbies or jobs, such as painting, that require air tools to get the job done
- For DIY projects faster, easier, and more professional
No matter why you are shopping for a new air compressor, it will likely fall into one of the above three reasons.
Once you know why you want an air compressor, you can use that information to determine if you really need compressors with extras such as LED lights, automatic shut off, or extra hose connections.
The Efficiency of Mini Air Compressor
We mentioned earlier why cfm, gallons, hp, and other ratings matter when selecting your mini air compressor. Compressors with lower horsepower ratings tend to reach their maximum cfm a lot slower than more powerful options.
This could spell the difference between minutes of waiting before you can do the work you need.
Generally speaking, DIY experts will want higher hp, cfm, and will likely want compressors that feature higher gallons in their tanks.
Mini Air Compressor Are Ultra Quiet
Many air tools and compressors generate a lot of noise. If you want to avoid disturbing your friends and family while you work, you will want to purchase quieter compressors.
For many shoppers, how a device sounds in operation is an important convenience consideration. That’s why most of our top five mini air compressors below are quiet during standard operation.
You should also consider storage since you aren’t always going to be using your mini air compressor. Models range in size and weight from pocket-sized models that weight less than a few pounds to workhorse models that weigh close to 100 pounds.
The heavier models also tend to be larger, requiring more garage space. The top five list below also includes a chart that tells you the dimensions and weight of our chosen devices so you know what to expect.
Buyers Guide: What To Look For When Shopping For Mini Air Compressor
The best way to shop smart for your mini air compressor is to be informed. That means knowing what ratings are important to look at, understanding what you actually need, and whether or not your compressor will be convenient to store or use.
Let’s dig in and see what that looks like. When you are shopping for any tool, there are certain key things that you need to know. Listed below are certain terms that you must check out first before making any purchasing decision.
Cubic Feet per Minute (cfm)
The CFM of an air compressor is the volume of air being delivered to the air tool. This rating is the most important in choosing a compressor.
Higher cfm ratings are better for larger jobs since they provide more air to tools. Some air compressors or air tools will offer a Standard cfm rating instead.
This rating refers to the expected cfm under standard pressure and temperature conditions (68 degrees Fahrenheit and 36 percent humidity at sea level.)
Pounds per square inch (psi)
Psi is a measure of the air force delivered by air compressors. Air tools require a certain amount of psi to operate efficiently. Most air tools require psi of 40 to 90 to get the job done.
Gallons refer to the tank size and are only important for tools requiring a constant flow of air. Examples include spray guns or sanders. Larger tanks let you do longer jobs before you have to pause to rebuild pressure in the tank.
Horsepower is all about the capacity of the motor or engine driving the compressor pump. This rating directly influences cfm output. Generally speaking, higher hp generates greater cfm.
Judging By The Numbers
When you’re shopping for a mini air compressor, you always have to keep in mind the ratings above.
We recommend that you shop for air compressors by looking at the tool you own with the highest scfm rating and purchase a compressor that has an output of 1.5 times the rating.
Let’s say you have a tool that requires 4.7scfm, you would want to purchase an air compressor that puts out at least 7.05 cfm.
If you want a compressor that can supply multiple tools at once, add up all of the scfm ratings together then multiply them by 1.5 for the cfm you need. Our list is based on price, weight, usefulness, and ease of handling and storage.
Since most home users don’t want to deal with heavier models that take up a lot of garage space, the options we’ll post below are all designed with the average user in mind. You can read a brief excerpt of the coming reviews with the following chart.
Whether you work from home, enjoy DIY projects, or want to handle household chores fast, finding the right mini air compressor is important. These devices save you time and energy, increase the quality and professionalism of your work, and offer convenience and portability that can’t be denied.
Our recommendations during this shopping guide are based on what we believe the average home user needs. But there are a lot of choices on the market for compressors so it’s always a great idea to shop around.
Use this guide and our recommendations to help you make the best shopping decision for your needs. We hope this guide will get you started in making the best shopping choices for your budget and needs.
