Better than your average 12v compressor
By Haoleb
I bought this compressor so I could air my tires back up after offroading. I wont go into detail on the advantaged of doing this but theyre significant enough that I wanted to invest in a quality unit vs just getting one of those little toy cigarette lighter ones sold in most stores. I decided on the 440P vs Viair's other offerings because of the air output and i wanted something with a bit faster fill times vs a higher duty cycle or automatic shutoff. As far as the initial quality goes everything seems to be pretty well made. The way the little base attaches to the compressor itself is a little flimsy since its just 4 little rubber standoffs but I doubt they will break if I dont just beat it around. The Hose is also of pretty good quality, Better than I expected even if its the coiled type that always seems to end up tangled in a big ball after one use. As far as using this compressor It does as advertised, runs smoothly and quietly and surprisingly has no problem pumping my 7 gallon air tank to 120PSI. I can air up my 32" tires in 13 mins from 18-50 PSI with the assistance of using the air tank as a resivoir. One thing to keep in mind is the warning stickers on "extreme heat" this thing will really cook after 10-15 mins of being on. You WILL burn yourself if you touch the metal parts. The handle insulates everything but keep it in mind. You cant just throw it back in the carry case when your done it needs to cool off. Only 4 stars because Of the price, and the amount of heat generated. So far ive put it through 6 or 7 airing up cycles so it will be intersting to see how the longevity is. Overall Its a much better unit than the cheaper ones out there that i have used in the past even if they do the job for occasional use, They are no replacement for something like this that will see heavy use.***Almost 3 years later update***I have had this compressor for a few years now and so far it is still going strong just like it was when I got it. It has a permanent home in my vehicle and I have had no problems with it. There are a couple of points worth mentioning, The pressure gauge that is built into the hose is kind of worthless, it will not give an accurate reading when you are actually pumping air, infact it is not really accurate period and really only gets in the way. Also, the way the air nozzle clamps down on the valve stem can damage the threads on your valve stem. I kind of wish I had a built in air compressor setup because I always get people asking if I need any help when airing up but then again, this is very portable. The carry case has held up well also. Still highly recommended!

By Haak
I can't agree more that it is a powerful compressor compared to its size. It delivers as advertised by Viair. It failed after five years of service.I am buying another Viair 400P Automatic as I write this review.
