Side by Side Comparison of: Viair vs PORTER-CABLE

I finally had to use this.I used to have a blue one from Walmart. I can't remember the brand but it was kind of loud and it took forever. I had a little sedan so I just dealt with and honestly assumed that was the best you could get with a 12volt compressor. I bought a little Tacoma a year ago and thought it might be a good reason to see what was out there.I used it this morning in the rain after finding I hit a screw. It was quiet and aired the tire up pretty quick. Even with the truck off and running completely off the battery. It was kind of a happy moment in a sad situation. It got me back up the drive way so I didn't have to change the tire in the road.The compresser is small and comes with a little bag too. It fits great behind my back seat. Love this little guy!!!

I'm a woman who always invested in cool sports cars throughout my life. When you get a flat with those kind of cars you can't even feel it. Therefore, checking your tire pressure on a regular basis is very important. I live in New England and weather changes also affect tire pressure. Gas stations aren't operated these days like the services they use to offer and the ones that do don't want to take time to do this. There is any money to be made. I always had difficulty getting the gauge on the stem of the tire and adding air. Usually, I lucked out and a nice man would see me struggle and offer to do it for me. It helps to be a sharp looking blonde with a fancy car. I decided to try one of these portable compressors. Read multiple reviews and finally decided on this one. It is one of the best things I've ever bought. It arrived packaged very nicely and I wondered if it would be as good as it looks. I have seldom been this impressed with a product. So portable you could carry it in your back pack. It easily screws on tightly to the stem of your tire and instantly shows how much pressure is in your tire and you add what you need. It has plenty of cord length to reach all 4 tires. It has a build in light for night use.I know longer have to take my bicycles up to a gas station and inflate the tires every year. I just think everyone should carry one of these in your car. Plus, what an unusual gift to give someone, especially those hard to buy for people. The item was on sale for half off. I paid some where in the low 40's for this item. I think every should own one of these. Thanks again to Amazon for providing me with easily obtainable information on almost every thing.

I live in Houston where I swear some roads contain more nails than asphalt. The VIAIR 85P Portable Air Compressor works perfectly for passenger cars, but it only goes up to 60 PSI. Consider another model if you have high pressure needs.I tried it out yesterday on a tire that was down to 23 psi. I connected the unit to the accessory power, fired up the car, attached the hose to the tire and watched the pressure gauge inch up to 33 PSI in about a minute. It was about as loud as my car engine and the front vents got mildly toasty. The VIAIR comes with a carrying case and has found a permanent home in my trunk.NOTE: the pressure dial reads about 3-5 PSI too high when the unit runs, but reads fairly accurately when turned off.Minor downsides:The "on/off" switch is awkwardly situated at the rear between the cord and hose; it should be on the handle. Also, the nice white power LED is buried among the hoses and wire where it really doesn't do much good. It should be on the front. Finally, they cut corners and used an unilluminated 120 PSI dial on a device that only goes to 60 PSI.But these are minor quibbles and the VIAIR 85P earns a solid 5 stars in my book.

I purchased the VIAIR 85P air compressor before a recent trip to the Oregon outback. In the past my tent trailer, on multiple occasions, has experienced a sudden loss of tire pressure while navigating some difficult and rocky terrain. This year I decided to be proactive instead of reactive and make an investment that would prepare me for possibly another flat tire episode. Before leaving on my trip I was able to check all of the tires and inflate them using the gauge that is easily readable and accurate. There was no issues on the 7 hour trip and before reaching my destination up a 6 mile rocky, rutty road I pulled out the compressor and deflated the trailers tires by 15lbs. This allowed me to make it to my final destination without any issues. The next challenge was leaving and making our way back down the same rocky and rutty road. Once again no issues and I broke out the compressor and re-inflated the tires to the correct pressure in a matter of minutes. I was extremely happy with my purchase. The only issue I could find was that the compressor can get a bit warm at the pump, but this is a minor inconvenience. The unit comes with a handy storage bag and is large enough to fit the compressor and the 12' 12V extension cord. It is also small enough that I can put it in the storage bin under the rear seat of my Toyota Tacoma. I would highly recommend this product and it will be a mainstay in my emergency gear.

This is ideal for my truck tires and travel trailer tires. Until just recently driving a truck and travel trailer, I never really needed my own source of compressed air. I need my own source of compressed air for the travel trailer tires because 1) it's a fortune now to put in quarters at the gas station and 2) the trailer is difficult to maneuver, and 3) it seemed like making adjustments at home or on a big roadside pull-out were much more practical. I realized this especially after being out in the middle of nowhere and having a low pressure issue with no pressure around for about 50 miles.So I bought this thing. I'll note that they should be more careful to call it a "12 volt" plug because this thing is not really meant to work with your car battery and would probably damage your car battery if you used it without the engine running. The instructions say to use it while the engine is running. The instructions also said to plug it in while it was in the "off" position. Personally, I felt like even that was a gamble and started my engine before plugging it in, just in case that it somehow arrived in the "on" position.I'll note it was manufactured in China but seemed nice and quiet and didn't jump around really at all. It does seem sturdy. The thing really gets hot. Probably if you weren't careful with the nozzle, it would melt if you rested it on a hot component.No problem filling my truck tires (with loads) from 38 psi to 45 psi. Took maybe a minute at most. The reading on the compressor is decent and I confirmed that gauge with an independent gauge.It took a shorter amount of time to bring my smaller passenger car tire from 29 psi to 34 psi. (less than 30 seconds)I didn't try it but you could fill your bike tires in about five seconds or a football, etc. It's gonna do stuff like that fast, fyi.I like the screw-on brass fitting for the compressor hose. In my opinion, the air loss is negligible during removal compared to toggles at gas stations, etc.It is meant to work with your engine running, drawing power actually from your engine, via your battery, although it does use the 12 volt cigarette plug. I am also lucky in that my tow vehicle has a snug 12 volt connector in the vehicle (the "cigarette lighter" outlet so that this sits snugly and so I can use the extension cord to get to all four truck tires and the trailer tires. I think you you might have a number of problems like blown fuses and under-performance if your connection is cutting in and out like if you have a wobbly 12 volt connection like those often are.Also I needed the extension cord to get around just for a regular car. I don't know why they don't just tell you that you basically need the extension cord with this, unless you're doing a go-cart. l was able to use the extension cord and with the truck facing my trailer, there was plenty of room to extend to the trailer tires. I was curious if this would work in the 12 volt outlet in the trailer (with the truck running and attached or plugged into the house) but frankly I just didn't have the guts to try it. And the extension worked fine to get to the trailer tires with the truck facing the trailer. (20 foot trailer with two axles)I was pleased it came with a canvas carrying case as many reviews had said it didn't come with one. It's smaller than I even thought. It's gonna drop in my truck toolbed like it's not even there.One negative is the mirror chrome top on top of the compressor is basically blindingly bright in the sun. If the sun is out, the thing is going to blast sun in your face (and passing traffic possibly). They really could have gone with a matte or just a less shiny metal on this thing. It's so bright and shiny I had to tap on it to see if it was plastic but it does at least seem to be some kind of metal.Otherwise, I'm very happy. If it holds up, it solves all my compressed air needs.

We bough this to top up/inflate the tires on our truck and car and I have actually been pretty impressed with it - especially compared to other pumps that we have had. To take a tire from more to less flat to inflated took about 6-8 minutes and the noise is far less than you would expect for something that was working at the rate this punk was. Some ares of the pump do get hot but again it was working hard so I would actually expect this. the footprint of the pump is pretty small and its easy to store without taking up a ton of spaceI know that there are some people that would find this on the too noisy side, but I actually think it is quieter than others that I have tried and the fact that it can actually inflate the tire so quickly has made things a lot easier

Perfect for our needs. Classy looking and a little loud but we use it mostly to fill tires and inflatables. But the recovery is very quick and the pressure very strong and best of all its a Porter Cable.

This thing has a quality feel to it. A little bit louder than I expected but works great. Perfect size. Nice look. Really satisfied with it. Don't forget to get the accessory kit with it so you can have blower adapters and other useful things.

Great. Light weight. Keeps up with brad nailer and stapler. A little loud, but a good trade for the weight

This is perfect for any home! I have mine mounted in my garage. It packs a ton of power and easily blows up car tires. I purchased mine in October 2016. Instructions are spelled out very easily.

Compact, lightweight, great quality, we keep it in the "basement" of our fifth wheel. I only need to air my tires up to 80 psi and this works perfectly for that.Get yourself an extra 25' rubber air hose (and fittings) to go along with this and you won't have to worry about kinking the plastic hose that comes with it.Just remember it has a small tank, you're not going to blow out your sprinkler lines or run an air gun with this. For tires and a quick inflate of some pool toys though, you can't beat it.

I bought this to have compressed air on the go for our motorhome. I needed something small, light weight and powerful and this compressor met all of that. It pumps up fast into the on-board tank. My only complaint would be the compressor outlet. I prefer to have quick-connects on my hoses to the compressor but the location of the discharge line complicates the installation of a quick-connect as it would stand out from the compressor too far out. Even installing a 90 degree elbow presents a problem so I simply direct connected the included coil hose and installed my quick-connect at the end of the hose.The hose is not so terrible and the included accessories are OK although my air inflation adapter (for air mattress) came cracked. There is a neat storage pouch on the back of the compressor but it lacks room to store the included accessories.Overall I am really pleased with the compressor.

Despite the fact I have had two units fail on me, I'm giving this product 4 stars due to the customer service.The first product failed within the first year. The valve somehow got bent during use (it's possible it was ran over by a tire). I paid shipping to send in the unit, and they sent a replacement unit.The second unit failed after 26 months from the purchase. The end of the cigarette lighter fuse became loose over time and fell out. Viair sent me replacement parts, despite being out of warranty.So 26 months later I still have a fully functional pump. However, if I were to purchase again, I would buy the 88p. It has a higher capacity and a faster pump. A time saver that would be useful for autocross and refilling my tires after offroading.A couple tips:1) Beware of metal, it gets very hot, I leave it outside the bag after use as to not melt the wires or pump line.2) The best reading you get with the pump is with the switch in the 'off' position.

I've used this to inflate my jeep after I air down to go wheelin'. I read a review that said it inflated to 45psi in 1 minute. 😐 :/ Absolutely not. I air down to 11 psi. I inflate to 26psi. It takes 5+ minutes. By tire 3, the compressor is hot hot hot. Today I gave it a 10 minute break or so and pumped up the last tire. I have done four in a row and you will absolutely burn your hand if you touch the metal on the compressor. Take into account the 5+ minutes a tire and it's close to a half hour deal for four tires. This isn't an issue as I air up the night before and am in no hurry. Having said all this, this unit is smaller and pumps air faster than an old compressor I have. It does only plug into the ac/12v adapter, but I understand you can buy an adapter if you wish to plug into your battery. For my purpeses and the price, I like it.

Strong and silent air compressor. I used to have an air compressor that had a plastic housing that would make all kinds of noises as it slowly but surely filled up the tire with air.This compressor fills up the air a lot faster then the cheaper models and is very quit in comparison.You can use this at night time without disturbing neighbors.The only thing that i would prefer is the connector that has a lever to lock it in. This one is a screw type and it does slow down connecting the compressor. Make sure your valve stem threads are in good shape.

Very nice!!Medium sound, as you'd expect. It's a nice "hum" and not a loud high pitched whine like the cheaper models.Its max warranty psi is 60, just enough to fill your spare tires (for you compact drivers like me)! It took my spare tire from 30 to 60 in under a minute almost.I loved it! Just be careful not to accidentally step on the lighter socket if you drag it on the ground.it also comes with a sweet bag to hold it in!!

I own a previous model of this compressor, which works fine, but tends to overheat a bit with prolonged use and does not include a LED light. The new version is improved in all respects and has a higher inflation rate to top it off. The built in heatsink is particularly welcome as the new version can be run without overheating for a lot longer. I still feel that the gauge is somewhat substandard and would have preferred one with a smaller scale, but a finer one (higher precision) - perhaps topping out at 75 PSI, in 1-2 PSI increments. The other improvement that I believe would be very welcome is to include a pro grade quick release chuck. The included screw-on type is secure and works well for balls and mattresses, but when pumping the tires - i.e. the primary function - it bleeds a bit of air on connect and disconnect - something that a quick release chucks are designed to avoid.

I use it for inflating trailer and light truck tires (70-80PSI) and it does so reasonably quickly and quietly for a $100 compressor. Compact. Fits through the small trailer storage compartment doors.

Nice compact compressor. Keep in mind that the 2.0SCFM/90 psi rating essentially means it the compressor can pump 2.0CFM of air at the input pressure of 15 psi, with a back pressure of 90psi at the output. This means the compressed air output volume is only 0.28CFM at 90psi. On the bright side, this rating is actually slightly lower than the real output of the compressor. It takes about 5 minutes for this compressor to fill my 1.5CF tank to 120psi.

I have been using this compressor frequently to add air to tires on my cars and bikes, inflatable toy for my sons to be used in the pool. I also use it to blow out leaves and dirt in my garage. It's very handy to have the unit in the garage. However, I wish that the hose is more flexible, and it runs a little quieter. Also, when it runs, the unit is kind of moving around due to vibration. No big deal, but it's just a little bothering. Overall, it's a great compressor.

This compressor does not come with a trigger nozzel BUT when my husband attached one to it's hose, it made a big difference in performance AND I no longer had to turn the pressure regulator on and off, which is a pain (it should come with one). If you get this compressor, invest in a trigger nozzel (check the PSI rating of the nozzel itself as they vary) and once attached this compressor is everything one would need for odd little jobs. The pressure nozzel I have can't go over 90 PSI without a chance of it being blown off, but 90-PSI is plenty enough. The design is very good for carrying around furniture, etc. Weight is not too much for me (I'm a 59 woman but have always been pretty strong) and I like the curled hose in that it does not go all over the place. I used it in my dining room to blow out the light fixture and the hose reached just tine and did the job without any problems. I HAD decided to return it but now I'M KEEPING IT.

Bought it to inflate tires on our fifth wheel, pickup truck, and hitch cushion, and it will do that very well. Took only about a half minute to inflate our big pickup tire from 45 to 60 #. That's fast compared to 12 volt units and almost as fast as a gas station unit. This is a serious piece of equipment, but I can't vouch for its longevity. Have only used to 3 times so far. I'd like to see longer AC cord. We bought a 40 foot extension cord for about 10 or 12 bucks. The adhesive plastic sheet that covers the front and on which are printed the labels/descriptions of the meters, etc. is lifting off. This happened soon after it arrived. Minor issue but otherwise we would have given this compressor a 5 star rating.

I had bought this pump to use both outside and inside. The low dB does allow indoor use without leaving family and pets with ringing ears - but the device is a lot wider than I had hoped making it a slight more cumbersome for my beloved to handle. Which is fine- I didn't want her to touch it anyways. The parts fit extremely well and the coiled air hose has great range for sitting the unit down and then walking about doing your thing. The central dial is a neat feature which allows one to increase/to decrease pressure for little jobs where just a small bit of air is needed.

The unit gets VERY hot when in use, you could cook an egg on it. The gauge gives a very approximate reading, in fact it gave me a 40 psi reading when my tire was actually only at 34 psi... it's a huge gap!

Worked great 1 time, then died.

Not bad, works, puts air into my tires just fine. Didn't blow any fuses on my RS 4. Wires & hoses were long enough to fill any of the tires.However, the way it actually attaches to the tire nozzle is inconvenient. It's not as simple as one would expect -- instead of being able to press the compressor's hose connector against the tire nozzle connector, like most air pumps, this one requires one to screw the connector on. Not ideal, but I'm sure I wouldn't care much in an emergency.

Ok I bought this on the chep, I wont lie! for the money this thing is still going, and I used it to fill both airbags on my truck, and tires on my trailer. This guy really is a life saver!now for 3 stars..1) it gets HOT, even using it in short bursts as reccomended it still gets quite warm2) it really sucks the juice! I had to get an extension cable for this as it wouldnt reach from the cab to the back of the bed... it melted! (my fault for not getting one heavy guage enough but it was all I could find at the truckstop)3) short cable... an extra 3' of power cable would make all the difference in the world!4) slow... really doesnt put out much air.. but it does the job.All of those are negatives, but the truth is it works, and as long as you arent in a hurry, you should be good to go!

Cigarette lighter connection impossible with most cars, as this unit draws 12 amps, which would melt the plastic dashboard material around the socket. Even the springs in the lighter plug cannot handle the current; they harden and break, breaking the connection. The only solution in most cases is to replace/lengthen the cable and use an inline fuse holder, along with quality battery clamps, not the ones on auto parts dealers' floor displays.

I've had this unit for 1.5 yrs and have used it maybe 10 times total. I took it out to use it last week and the hose has a new leak where it meets the plastic housing. I'm guessing it just dry cracked. I keep it stored in my enclosed garage and the weather here in SC is generally not that drastic from season to season. I contacted VIAIR and even though it's out of warranty, they said I could send it back for a new one. Very Happy about that since these things are kinda expensive. We'll see how long the new one lasts. So 5 stars for customer svc but I could only give 3 stars for the product itself.

Having lived with this compressor for a bit now, I decided to write a review that I feel better represents this product than most I've read.First off, it functions fine. That is to say it doesn't leak air, is quite portable, regulator and gages work, all as to be expected. It is not as quiet as some have indicated. This is not a surprise for an oilless compressor, but don't mistake it for the relative quiet of an oil type. The biggest issue I have with the little Porter Cable though, is it's balance. This thing wants to fall over, a lot. It falls over in the truck, it falls over on the job. The rubber feet form a much smaller footprint than the effective footprint determined by the enclosure. This, combined with a center of gravity that's just about over the middle pair of "feet" exacerbates this problem. Because of this one has to take extra precautions with as it is bound get damaged.

It is too small.Originally I bought it inflate my tubeless mountain bike tires and it works great for that. They I found more uses for it like blowing off saw dust of my miter saw and things like that. The compact factor is interesting but there is a not much larger model made by Ryobi which you can buy for the same price when on sale and has a 5 gal capacity which will greatly extend the applications of the compressor.

I bought this to basically fill tires. For that it works fine. However, I also have a Makita portable compressor that outshines this one by miles. If I was to do it again I would invest in something better. Crappy hose.

Does the job as long as plugged up but doesn't hold a lot of air for reserve

It would have been great, but the regulator broke.

I'm working through a warranty process, I'll update this if it starts to work.The regulator valve leaks and no pressure can get from the tank to the hose. So far it's a noisy paperweight.Edit: I went through the warranty process with the manufacturer, and I recommend using the Amazon return if at all possible. Porter Cable outsources to local shops, and then the local shops ship stuff where they need to go. It took about 8 weeks for the shop to deliver, and by deliver, I mean fix it. I had to go to the shop to pick it up.I'm not using the compressor for anything trying, but it's been functioning fine since the regulator valve repair. It'll compress air up above 120 psi, I didn't check all the way to 150. It's loud, but unsurprisingly so. I added an attachment for filling bike/car tires, and I'm using an adapter for presta valves.

Product worked well for topping off my jeep tires,blowing up flotation for the pool,and sports balls. However, the connection to the power source broke rendering the device useless now. According to amazon I'm out of the return window and stuck with the defective unit.

I used it when I first received it. It worked great. I tried to use it today, it topped off one tire ok. Then stopped working after about 30seconds. It will work for a few seconds then stops. I will be checking into exchanging it for another one

Loved the power and speed. The heat sink at the top gets hot enough to burn you. Also it has blown out the AUX power sockets on my Silverado without a fuse blowing. Easy fix but I would not buy again.

Purchased this pump four years ago. The pump itself is strong, but the rest of the build is sub-standard. After four years of intermittent use, the power socket is broken (happened soon after purchase, flimsy plastic, taped it up with electrician's tape), the air hose is frayed, and the power wire is exposed where it meets the pump body. Plus, it now blows fuses on my truck, both 10amp and 15amp fuses. I'm discarding this and buying something else. In short, it did not really last as long as I had hoped.

Worked for a few pumps but then started blowing fuses all over the place. Replacing fuses is no fun in newer vehicles! Then it overheats easily and died within 4 months.

I'm reviewing this after about two months. I used this to pump up a tire with a slow leak for about a month. The fuse didn't blow, but I have not checked the rating. The pump maximum pressure is about 39 psi and then it just jumps. I guess there is a check valve at this point or something to protect the pump/tire. That's enough pressure to get back on the road. I don't care for tools made with plastic parts that can't easily be replaced. And the hose can't be replaced - at least not without dissembling it. The attachments are just clipped on the outside, so you may want to store this in a container. Over all it does pump up a tire without jacking up the car, but I'd still do, if it's not too much trouble.Edit: The pump died after two years of occasional use. If I can find it easy to repair then I may rejoice again over this pump. But it, just sitting now in a box of broken miscellaneous right now.

Received this compressor yesterday and am disappointed at the design quality. First of all, the connecting rod that drives the piston is belt driven, with what looks to be a flimsy cog belt. Second, the connecting rod and piston are completely exposed to the elements, only shrouded by the plastic housing, and the fan is blowing air over it so if used in a dusty environment dirt will be blown directly on the piston which would dramatically shorten the life of the compressor. Third, this unit shuts off at 135 psi, not the heavily advertised 150psi, and kicks back on at 115 psi. Forth, after only about 5 minutes of use the sealed bearing on the piston rod was slinging grease out of it, this will shorten it's life due to lack of grease eventually. This is not the design quality I expected from a Porter Cable product. I will keep it to inflate trailer tires while on the road, but I don't expect it to last long, if I am wrong I will update this review, but as it stands I am not impressed.

The hose leaks so the product does not hold any air pressure in the tank.

Good

The compressor is okay. All the attachments except the tire inflator chuck are junk.No quick release attachment is provided.Air out put is marginal for winterizing a motor home or for air driven tools.I definitely would not buy this compressor again !!

I used this once and it worked ok. My tire pressure was really low this past Sunday and when I needed it most it doesn't work; flipped the switch on and off... nothing. I had to go to a gas station to fill up my tires which is the reason why I purchased this to have as a convenience. So much for that. I want my money back!

Lasted 13 months(so, out of warranty by on month...grrr) before it stopped working (completely dead, no light and motor wont power on). I followed all the instructions and always had the engine running when using it, but it gave up anyways. When it worked, it was fine. The pressure gauge is pretty inaccurate, but that goes for all compressors I have used.

Air nossel wouldn't seat correctly to the valve stem after about 15 uses.

Maybe I had bad luck, but my unit stopped operating 2 months after I bought it. I used it only twice. During the second time, after I turned it on, it burped once, the indicator light went off, and it became as dead as a brick. Switching it to another car's 12v outlet made no difference. Sending it for warranty repairs requires postage, a $20 "inspection fee," AND return postage, according to the manufacturer's website. Total cost is likely to exceed the purchase cost of this product. I hope my experience is not representative, but be assured that the warranty is completely useless if something goes wrong.

This air pump broke the SECOND time I ever used it. What kind of quality is that?I am very disappointed with this product and will be contacting customer service for a replacement.

Seemed like a solid product, well designed, liked the nice brass fittings that screw into the valve stem. Bought it for a car tire with a slow leak. Pump worked great about 6-7 times and then just died. Light still works, but pump does nothing. I spent more money on this product hoping it would be a quality item that would last. No such luck. Should have bought a 30 dollar one. And of course it lasted one month more than Amazon's return policy. Last pump I had was a cheap plastic one, lasted me about 10 years before I lent it to a friend and never saw it again. Probably still works. I'll try to find a new one like it.

Great compressor. My dad gave me a huge 30lb compressor, it took up way to much space, was way to loud and just overkill for my use of just keeps my tires inflated during winter and just blowing air to clean things.I researched several options and decided on this one, its works great. very light and portable, however I wish i had gone for larger one as this cannot top off all 4 tires (Acura TL) on 1 charge. Also the power cord is very short, I almost wish it just came with male end and let me plug in an extension cord. Overall very happy with it.UPDATE3 months later its dead. probably used it like 10 times. Amazon is amazing and let me return it still. Porter cable i will never buy your junk again.

At 3 months old and only used a hand full of times the motor failed and started shooting sparks and smoke out of the side vent! While on the phone with the warranty department I was told to return it to sell for a replacement. Amazon will not take returns after a month on this product. Then they told me to drive it or ship to a service facility, both options cost a third of the price of a me unit. Don't waste your hard earned money on this hunk of junk just to have it fail in the middle of a job...

Purchased unit 2 years agoHaving trouble with regulator - it will not hold air above 25 psi without releasing all air in tankNeed 75 psi for my staple gunWill call porter cable and see if they can advise a simple solutionWorked well before thisUpdated: Called Porter Cable. It needs service. Called the service center they referred me to, and they charge a $40 diagnostic fee. For an item I paid $110 for it is not worth it. Very disappointed, as I used it for under 30 hours.

Bought this compressor back in August 2014. About a month ago (11/2015) the unit broke while using it. There is some sort of leak and it is unable to produce any air pressure at all. I only used it about once a month while I had it.

Air Chuck broken. Not sure if unit is good or bad. Decided to order new tire inflator and connector set before returning.

After reading all the positive reviews and comments, and taking into account the three 1 star ratings before I purchased this item, I thought the Porter-Cable CMB15 air compressor would be sufficient for my modest needs to inflate car tires and occasionally blow dust off of things. As noted by other reviewers, the accessories are very cheap, but I was prepared for that and ordered the Coilhose Pneumatics hose and a 7-piece Milton connector kit, which are great.However, the CMB15 failed within the first 5 minutes of use while attempting to inflate my car tire. It failed with exactly the same symptoms as Tim-A reported: a massive internal air leak developed inside the shroud, and based on the loud hiss of escaping air, the leak is somewhere on the left side of the unit (definitely not the safety valve). No way to tell without tearing the unit apart if it is a ruptured tank or blown regulator or failed internal hose/connector. Thank goodness it failed immediately instead of months later on the 3rd or 4th use like poor Tim-A. Amazon's easy return policy saved me in this case - I opted for a refund rather than a replacement. Beware of this model; I should have heeded Tim-A's review instead of all the 5 and 4 star reviews!2013-12-08 Update: Amazon received the returned failed product and credited my account. I then bought this air compressor from Amazon: California Air Tools CAT-6310 at just under $200. Yes, it was almost 2x more expensive and weighs a bit more, but it's extremely quiet, has a much larger tank, and has a much more reassuring build quality. I am so far very impressed and happy with the CAT-6310 as a basic home compressor.
