Best Portable Air Compressor Review: Viair 300p Compressor

The worst sound in the world is the whine of a tire going flat. It doesn’t even take such a drastic loss of pressure to make your day go bad though. Walking out of the house to see your car sitting slightly askew in the drive, and not having any way to fill up the tire will start things going south real quick. You’ll never have to worry about being stranded on the road, or stuck at home with no way to get to where you need to be again if you have a portable air compressor like the Viair compressor 300p.

No Outlet Required

That’s right, you don’t need to be anywhere near an electrical supply other than your car’s own battery. The Viair air compressors run on energy generated by the car itself, so even if you’re on a deserted highway, you can fill up that tire and be on your way. The Viair 300p is a 12 volt air compressor that you hook up to your car’s battery system to generate its power source. It can fill up tires as big as 33″ so it is great for autos ranging in size from small sub-compacts to heavy-duty pickups.

Everything You Need in One Box

When you are looking for the best air compressor, consider several aspects. First, of course, you will need to look at prices. The Viair compressor is an affordable tool that won’t break the bank. Best of all, it comes with absolutely everything you need, so you won’t have to run out and by accessories, or parts to get the job done. Check what comes in the box here.

Pressure Gauge and Power Cycle

The unit comes with a 5-in1 gauge so you know how much pressure you are adding, and when to stop. It also comes with battery clamps to attach the unit to your car battery, an air hose and a carrying case with enough compartments to hold all of your supplies and keep them safe when not in use. The Viair 300P has a 10/30 pressure cycle so you get 10 minutes of filling time for every 30 minute charge. If you require more air after 10 minutes, you must let the unit recharge for an additional 30 minutes. You can also use the pressure gauge to measure decompression when you need to lower your ATV tires, or other sport vehicle tires to optimum levels.

Handy Accessories

Along with the standard equipment, the Viair 300P Portable Compressor also has its own sand tray to control the vibrations when in use. It has a three-piece tip kit to fit a variety of tires, and other appliances as well. You can use this 12 volt air compressor for power washing your car for small areas where dirt and grime are the worst. It also has an inline fuse holder to prevent motor damage.

Stuck at Home?

Electricity may not be a problem, but if you don’t have an auto air compressor, all the electricity in the world won’t fill those tires. If you have the Viair compressor you are good to go. It won’t even take the power cycle timing to get you moving again. The unit comes with an 8-foot power chord to plug in and fill up your tires to the proper pressure. The Viair 300P will get you rolling again at home or on the road.

Drawbacks of the Viair 300P Compressor

It’s the best portable air compressor, and that means its only for light-weight use, and small jobs. This isn’t the machine to power wash your deck, your whole car, boat or house. It won’t run power tools that make good use of bigger air compressors for long. If you need a quick power driven wrench to remove or rotate your tires, the Viair 300p can do it. If you need to sandblast the driveway, or the bottom of your boat after a long season in the water, the Viair is going to take a long time to do it. Bigger jobs require a bigger air compressor, but you will sacrifice size and convenience of a more portable air compressor.

What others are saying

Portable air compressor reviews on Amazon show how much Viair users love their portable auto air compressor. The product has an overall rating of 4.5 stars, and 99% of the reviews are completely in favor of the compressor, giving it a full 5-stars. Some of the comments I found on the site are:

“Ideally I wanted an on board air compressor in my new FJ Cruiser for going off road. But I needed an air compressor now, so I opted for the portable kit thinking I would install it at a later time. Now that I have it in hand and have used it, I am most likely going to keep it as a kit.” – J. Rope, Cape Cod, MA USA

“The Viair 300p air compressor is an excellent product for both airing down and pumping up my 30 inch tires on my Jeep.” – John A. Hong, Prescott Valley, AZ United States

“Solidly build, is very quiet, and will add about 10 psi of pressure to my Dodge Neon’s tires within 30 seconds… better than I expected.” Matthew Gawel “Truther1″, Detroit, MI USA

“A godsend when doing this chore… well built, works as expected.” – Ross Bulloch, Midlothian, VA USA
