While its CE certification can be welcome news, it is the presence of an integrated overheat protector that will give you peace of mind every time you use this tire inflator. The overheat protection system instantly shuts off the device if it reaches a temperature exceeding 167OF.

The EPAuto is the most portable air compressor on this list. Weighs 3 pounds, meaning you can conveniently handle and move it about. It makes an excellent equipment in the trunk.

The auto shut off feature is the best one that shuts off the inflation automatically when the required amount of air is filled up with the tire prevents it from bursting.

We were impressed with the pump’s elaborate safety system. It will automatically shut off when the tire reaches the desired pressure levels. The manufacturer has taken measures to prevent overheating as well. The other advantage we drew from the led flashlight. It provides bright light for nighttime pumping.

Another good reason to get this air compressor should be that it allows for multiple uses. You will find that with this single product, you can inflate tires on cars, sedans, bikes, and midsize SUVs. This makes it good for someone who might have different types of vehicles.

What experts didn't like

It takes some time to raise its pressure levels according to some portable air compressor reviews
- Auto Expert Guides
Our primary concern is that pumping slows down when the display unit is at a higher mode of PSI. Also, the light on the unit cannot be turned off.
- Car Outfitter

Will not handle truck, pick-up or large SUV tires. Combined reach of air hose and cable just 10 feet.
- BestReviews
The power cord is only 9 feet long. While this is long enough to run from the cigarette lighter to the tires on most cars, this length is the absolute bare minimum length you should have.
- Garage Pro Reviews
Does not work for truck tires
- SafeRoad

The main problems include that it is not heavy duty, so you cannot run it for long periods or use it too much without causing trouble and that the screw on valve allows for air to escape, which means you have to add more air than you really need to get your tires at the proper PSI.

However, it will not be recommended to fill the air on the truck and more substantial vehicle.

An Overview On Portable Air Pumps

A flat tire never happens at a convenient time. Whether you’re on the road or your car is parked, changing a flat tire can be a pain, even if you have a handy spare in the trunk. That’s where a portable air pump comes in. An air compressor can fill your tire to help you get from where you are to a tire repair shop without having to try to switch out a spare.

But the best place to keep your air pump is in the trunk of your car, which means portability is essential. With a portable air pump, you aren’t limited to storing it in your garage. Just pop your trunk and you’re ready to go. Look for an air pump that’s small and lightweight enough that it won’t be in your way when you’re transporting groceries, luggage and other essentials.

Expert Vicki Liston is writer, producer and narrator of “On the Fly…DIY,” an award-winning home improvement and DIY show. She’s personally seen the value of a portable air pump, which has helped her out with a flat tire or two.  She’s also found that some air pumps can even come in handy for those around-the-house emergencies.

“Ensure you have a set of various nozzle adaptors and the possibilities are almost endless,” Liston says. “Unexpected house guests? That air mattress will fill up quickly and you are ready to entertain in no time. Do the kids need the wading pool and all 24 of their inflatable toys blown up? No problem and you can enjoy the rest of the afternoon out in the sun and watching them play.  Have a dust-laden item you need to clean? Use your pump like a mini blow gun and be done in a few seconds. Arrive early to a birthday party only to find the parents dizzy, out of breath, and still blowing up that 100-count pack of balloons? Yes, your portable air pump will prove that not all heroes wear capes.”

Ease of use is another important feature to look for in an air pump. Many models feature auto-shutoff, which means you simply input the desired PSI ­— which refers to the pounds of air per square inch — and the unit stops pumping once you’ve reached it. Most auto manufacturers recommend a PSI of between 32 and 35 when the weather is cold, but check the sticker inside your drivers-side door to get information specific to your own vehicle.

The Portable Air Pump Buying Guide

  • One of the handiest features on today’s air compressors is auto shutoff. Instead of monitoring it as it inflates your tire, you just input the amount of air you need and it automatically stops once it gets there. The EPAuto 12V DC Portable Air Compressor and VacLife 12V DC Air Compressor Tire Inflator, 150 PSI both use automatic shutoff. Although FORTEM Portable Air Compressor, 150 PSI has auto shutoff, it’s important to note that the PSI tends to read high, which means it may shut off before it’s reached your desired inflation level. With any air pump, though, you should monitor it until it’s finished and make sure it shuts off when it should.
  • You’ll find while you’re shopping that many air pumps are built to operate from your car’s cigarette lighter, which is a 12-volt socket. The Kensun Portable Air Compressor Pump, 12V will connect both to your car socket and a wall plug, making it something you can use in your garage. The EPAuto 12V DC Portable Air Compressor, FORTEM Portable Air Compressor, 150 PSI and VacLife 12V DC Air Compressor Tire Inflator, 150 PSI will work only with your car’s 12-volt plug.

“I recommend purchasing a unit that has two power plug options – a 12V car socket and an AC wall plug,” Liston says. “This will allow you to power the unit whether you are stuck on the side of the road or working out of your garage.”

  • Liston also recommends a power cord that’s at least 10 feet long to give you the reach you need. With the VacLife 12V DC Air Compressor Tire Inflator, 150 PSI, you get a power cord length of 11.5 feet. The EPAuto 12V DC Portable Air Compressor and FORTEM Portable Air Compressor, 150 PSI come close, at just over nine feet. If you opt for an air pump with shorter reach, you’ll need to keep an extension cord with your air pump so you’ll have the cord length you’ll need in an emergency.
  • The power of your air pump will determine how long it takes to fill up your tires. The Kensun Portable Air Compressor Pump, 12V puts out 11 liters per minute thanks to a 120-watt motor. With the FORTEM Portable Air Compressor, 150 PSI, you’ll only get eight minutes of use before needing to let it cool down.
  • The EPAuto 12V DC Portable Air Compressor has a safety measure in the form of an overheat protection system. If the device reaches 1670 degrees Fahrenheit, the unit will shut down to protect it.
  • Some air pumps come with special nozzles that increase the variety of items you can inflate. The nozzles that come with the EPAuto 12V DC Portable Air Compressor, Kensun Portable Air Compressor Pump, 12V, FORTEM Portable Air Compressor, 150 PSI and VacLife 12V DC Air Compressor Tire Inflator, 150 PSI allow you to inflate various vehicle tires as well as basketballs and swimming pool toys.
  • Chances are, you plan to keep your air pump in the trunk of your car, making portability essential. The FORTEM Portable Air Compressor, 150 PSI is both compact and lightweight, at only 8 x 6.5 x 3.3 inches and 1.9 pounds. The EPAuto 12V DC Portable Air Compressor and VacLife 12V DC Air Compressor Tire Inflator, 150 PSI are also lightweight, portable options at just around three pounds. The Kensun Portable Air Compressor Pump, 12V is better for garage storage, at five pounds and 11.8 x 4.3 x 6.7 inches.
  • Emergencies typically don’t happen when it’s most convenient. If you find yourself stranded with a flat tire late at night on the interstate, a light will come in handy. The EPAuto 12V DC Portable Air Compressor, Kensun Portable Air Compressor Pump, 12V, FORTEM Portable Air Compressor, 150 PSI and VacLife 12V DC Air Compressor Tire Inflator, 150 PSI all have built-in LED lights so that you can see what you’re doing no matter how dark it is.
