Rated 4.8 out of 5 by 16 reviewers.
Rated 5.0 out of 5.0 by Awesome portable compressor Pros-It's small enough to carry in your trunk right alongside your jumper cables for emergencies. It's easy and hassle free enough to use all the time instead of unrolling your garage compressors hose. Just plug it into the 12v socket in your vehicle. Has a built in psi gauge. On/off switch right at your fingertips. It's light, has rubber feet to prevent it from "walking" off during use. Have used it a bunch of times to adjust tire pressures on my 3 vehicles with no issues. Cons- Takes a little longer to inflate tires than a service station or a 2 stage compressor. Wish the power chord was a few feet longer so you can get to both sides of the vehicle without unplugging. March 28, 2012
Rated 5.0 out of 5.0 by get the job done Sturdy construct, inflate four tires in a reasonable time. Power cord should be longer for convenience. The tie come along is handy. February 3, 2015
Rated 4.0 out of 5.0 by I am pleased with my purchase. This inflater works quietly and smoothly. The gauge is accurate and I like the fact that the hose screws on to the valve stem on my tires. (I have had others that popped off or leaked all the time.) The power cord needs to be a little longer. This inflater aired my tires quicker than any I've had before but this one costs more than any I've had before. Overall I'm very satisfied. January 6, 2015
Rated 5.0 out of 5.0 by Best portable compressor I have bought a lot of junky portable compressors through the years, including the stuff at my local Home Depot store. This Viar compressor (available on but not in my local store) is far superior. Really really good. Would suggest that Home Depot start stocking it in their local stores. April 29, 2012
Rated 5.0 out of 5.0 by Viair 85P portable compressor well made product, screw on air connection for valve stem -- better than other sytles which could damage expensive rims. Very long power cord. November 13, 2013
Rated 4.0 out of 5.0 by 85P Portable Compressor Small and easy to use but the cord length isn't good for vans. I bought an aftermarket cigarette lighter to battery terminal so I can also power this off car batteries. Works well and we have 3 cars. The gauge reading differs from my built in car gauge….don't know which one is correct! In general, you need to hold the switch on til the gauge reads about 1 to 2 psi over what you desire and then let go of switch. Let it cool a bit and then take a reading. January 25, 2014
Rated 5.0 out of 5.0 by Running strong after 3 years I was really surprised how powerful this little thing is October 26, 2014
Rated 5.0 out of 5.0 by well made This compressor is rated for around 65 PSE This is enough pressure for any size tire, would even get a large truck tire inflated enough to get to a service facility. There are lots of compressors that claim much higher pressure ( 350 ) PSE but the cubic ft. per min is more important. The 85 P is much higher in CFM which is what's needed to inflate a tire in reasonable time. May 13, 2014
