I love my compressor and have been using one for several years until the valve clip that locks the connection to the tire valve stem broke. I use my replacement compressor on 19.5 inch RV tires that require 90 psi and have had great results keeping my tires at the correct pressure. Thank you, Ron H.

I researched many portable compressors and this one is the best value. the only thing is the power cord is way too short. I had to splice more line in so i could use it on my truck it would not reach the right rear and was very tight on the left rear. it is a 2500hd crew cab long bed. all in all good product.

I'm using the VIAIR 90R in case of an emergency when my air shocks need air while I'm camping. It's compact and easy to hook up. I'd recommend it to anyone with a simislar application.

I do like the Viair 90P air compressor in most respects. The problem is the length of the power cables anf air hose make it nearly impossible to fill all tires on my truck. I ended up replacing the air hose with a quick disconnect and I use a coiled 25 ft. air hose. I can fill all the tires now.

This is the quietest and smoothest air comp I ever used. Like others, the power cord should be 5' longer as even in my Tacoma it just stretches to reach that pass rear tire. VIAIR come on add some cord and you would have the perfect unit!

Nice little compressor, think it will suit what I bought it for well ( air on the trail ).

On my first use of the VIAIR 90P, pumping air into my home auto, I needed to add 4 lbs, from 28 to 32. Pump worked great, but I never was able to get air pressure gauge to give me proper reading, It was over 100 lbs, when the reading should have been 32. I constantly needed to stop pump and check pressure with tire pressure gauge. Minor inconvenience, but like other portable air compressors I have had.

I bought this to go with my Firestone Air Bags. I like how it gives the air pressure without the need to remove and check again with separate pressure gauge. Only problem is that the cables are not long enough to reach from the truck battery to the rear of the truck. I am using my jumper cables to extend the reach.

I like many other reviewers got tired of trying to find a gas station that offers a free air pump that still works especially during the winter months. Thus I did my research online and found all models of the Viair portable air compressors to be the top performers. I decided on buying the 90P model over the less expensive 70P and 85P models because it connects to my car battery for power and thus will not blow a fuse related to my car lighter socket that only offers 10 Amps. The 90P is very sturdy and works quickly, with easy instructions. The gauge is accurate when the 90P is still connected to your tire but turned off, thus I toggle between the on and off positions during use to obtain my proper tire PSI reading. I now have peace of mind when traveling with the 90P within my 2000 Honda CR-V but I usually top off my tires in the comfort of my garage before I hit the road. I have used the 90P twice since my 1/12/2011 purchase primarily due to a slow tire rim leak but I'll take care of that next. I can easily reach all 4 tires on my vehicle and the travel case is a nice plus. You won't go wrong with any Viair purchase!
