Product Description
Viair 90P Portable Compressor is a small but powerful portable compressor kit capable of inflating up to 31 inch tires by simply clamping the power leads to the battery terminal, connecting the lever style tire chuck to the tire valve stem and turning the unit on. Tire pressure can be monitored using the gauge mounted on top of the unit. Just turn off the unit to take an accurate pressure reading since air flow into the tire will show an inaccurate pressure reading. Has a 15 percent duty cycle, 120 PSI maximum working pressure compressor.

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

Amazon Verified Purchase
I got this tire inflator because I didn't want to be dependent on my local gas station to fill my tires up. Last time I went there the air compressor was broken, so I finally bought this.
This unit hooks directly up to your car's battery. My 2010 Honda Accord only puts out 10 amps through the DC outlet inside the car, so I decided to get this one rather than similar units that I have seen that hook up inside your car rather than the battery. I have read other reviews about some of these inflators blowing fuses in the cars, so I was aware of that issue ahead of time.
After connecting the clamps to the battery and turning on my car, I filled up all my tires just to top them off. The compressor is relatively quiet (certainly not loud by my definition) and added about 2 psi to each tire in about 10 seconds for each tire. The unit was a little warm after all four tires, but certainly not anywhere near hot to hurt my hands from touching the metal heatsink. It probably gets hotter if you leave it on for longer, but for periodic tire inflation maintenance, it seems like it is rugged enough to handle it.
The nozzle is a clampdown type which also has a release switch. You press the release switch once to lock it into the release position, and press it again to close it back up.
Most of the parts are made of metal, not plastic. It does have rubber feet on the bottom to absorb the vibrations though. The length of the hose and DC power cord put together is just enough to reach all four tires on my car comfortably. The bag that comes with it fits all of the parts with some room to spare (I also keep my tire guage in there now).
All things considered, I think this is a pretty good unit. The construction feels good, which is reassuring since I had another tire inflator a while back that did not last long. It does everything I expected.

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.
