Great compressor
 
Review Date: January 12, 2010
Reviewer: Daniel Ji, los angeles, ca
Pros
- Quiet operation (specs state 67db) much quieter than the gasoline station compressor
- on/off switch
- Cables are long enough to reach my rear tires on a full sized sedan with ease (5ft air hose + 11ft power cable).
- Filling performance/speed on par with gasoline station compressors
- Can work on tires up to 33"
- Sturdy metal construction quick connect device

Cons (very minor critiques)
- I wish carrying bag was slightly bigger or the location of the air hose outlet could change. When I put the compressor in the bag it seems like it could unnecessarily bend the hose if I' not careful. This is just a very minor complaint.
- Haven't gotten the pressure gauge to read correctly.
- 1 year warranty (wish it was 2 or 3 years)

If you goto viair's website, the 70p is for up to 175/65/15 tires, which is 15" tires. I had 18" tires, so that's why I looked into the 90p.

I also looked at the Masterflow/Q-Industries MF-1050 / MV-50. These pumps are spec'd similarly to the Viair 90p. One confusing thing is that the MF-1050 and MV-50 are the same exact pump - did some research online. In the end, I opted for the Viair brand, b/c their website and company history seemed more solid than MasterFlow.

I think a lot of people who get compressors w/ a power rating of only 15A (those that are powered by cigarette lighters or 110v cords) have a pump that's just too underpowered for their needs. That's why it breaks down or they have an unsatisfactory experience.

This Viair 90p definitely meets my needs and I'd recommend it to all.
Works well as intended

I've had the little Viair 90p for about three years now. It's used to pump up tires following off-road trips and sees plenty of use. When other compressors have difficulty pumping up four tires this little thing just keeps going and going pumping up tire-after-tire even in the heat. Other compressors thermal out, overheating and shutting down. The Viair puts out 1.77 cu.ft. of air a minute and puts a 33" SUV tire from 18 psi to 36 psi in about four minutes. It uses a clamp-on valve connector which is quicker and easier to use then the kind that screws in place. Between the electrical cable and air hose it reaches all corners of my SUV with a bit of room to spare.
Well made unit

Got this to carry in my Mini (along with a tire repair kit) since I went from the run-flats to real tires. Nicely-made unit, reasonable size, and comes in a nice soft case to put in the car. Worth the extra compared to the majority of the junk that's out there at lower prices.

Reviewer: Gary,
I recently switched from run-flat to regular tires on my Corvette, and needed a backup since my car doesn't have a spare. I wanted a portable compressor that was powerful enough to fill the large tires quickly, and the Viair 90P seemed to fit the bill.

I've only had it a couple of days, and have only used it once to balance all four tires to the same pressure, but it works admirably. It's very quiet, and the battery hookup wires are long enough to easily reach all four tires. The hose is also nice and flexible, making storage in the bag very easy. Another plus is that the bag easily fits in the hidden storage area in the hatch area, keeping the compressor out of sight. The only complaint is that the pressure gauge reads about 4 psi too high, but that's not a real problem since I always use a regular gauge anyway.

All around, it's a very good buy at a reasonable price. And even using the free shipping from Amazon, it arrived two days after leaving the distribution center in Kentucky.

Reviewer: John doe,
I'm very impressed by the performance of the 90P Viair compressor. I originally had wanted to buy the 70P Viair compressor because it was cheaper and because it has the car accessory plug-in (instead of the alligator clips), but both my cars has a 10amp accessory fuse and I did not want to take the risk of blowing them every time I used the compressor (I believe the 70P has a 14 amp draw). This led me to consider either the Masterflow, or the MV50, because of their reviews in Amazon. After reading many reviews later, I decide against both of them, mainly because I wasn't very keen on the screw-on air chuck and the coil spring hose. I wanted the snap-on chuck and didn't want to have to stretch a hose to get to a tire. Plus, I noticed that if the hose is attached to the farthest tire, the gauge would wind up being on other end of the car since it's attached to the compressor. I know these are small inconveniences, but for me, I wanted easy on, easy off, no pulling, and the tire gauge by the tire. The 90P looked to have what I wanted plus I thought it looked sturdier and well built. The price of the 90P was a little more than I wanted to pay but the reviews I read convinced me to give it a shot
I have a couple of tires with slow leaks that I haven't had a chance to bring in to fix. I was amazed at how fast it pumped up my tires from about 25lbs to 32lbs (both tires in about 1 min. each). I also topped off all four of my sister's tire in a few mins. The attached air gauge was just as accurate as my hand held gauge, and the bleeder valve on the chuck is definitely a plus. I know I probably won't be using the compressor as much, once I fix my tires, but WOW, you really get what you paid for. Not only is this fast, it quiet. I'm sure the Masterflow and the MV50 performance are probably comparable based on their reviews, but overall, I'm very happy with my choice. I have two other compressors which I paid about $25 for and they are twice as loud and take about 10 times longer. I'll probably keep one as a spare and throw the other one away.
Of course, after I bought this and used it, I found out that there is an 80P viair out there, also with the snap-on chuck, but for less. I would have gone and exchanged the two to save some money, but, I'm so impressed with 90P's performance that I didn't want to go thru the hassle of mailing it back and risk being disappointed. Will probably try the 80P if I need another one, but if they ever discontinue the 80P, I would definitely buy this one again.
I didn't give this a five star because I thought the wire should have been just a little longer and the price more inline with its competitors.

PRO
Snap-on air chuck with bleeder valve
Fast and very quiet.
Gauge is accurate.
Light and well built.
Fits well in bag (no need to detach hose to fit)
No filters to change/replace.

CON
Price
If you have a big truck, the wire may not reach your furthest tire. I have a pilot and I have only a little more than a feet of leeway (from battery to furthest tire
