Thoroughbred of Tire Pumps!

We lost tire pressure on a run-flat tire while driving in western Montana on our way home to South Carolina. Like many things ‘Mercedes’ there wasn’t a quick fix available in the entire state. Turns out we had to drive to St. Paul, MN, for repairs, a distance of 1268 miles. . . on a flat tire. Why drive on a flat tire? Well, the tire is a Pirelli 275/35 R20, which slightly rarer than chicken teeth. On top of that the key that unlocks the wheels was stripped and not useable. (Special order from Mercedes.) This meant stopping every 30 miles to add air. It also meant adding air every morning, and after every rest stop or meal break. (FYI; lost count of fills after 50 or so and I am now SURE I can be a big help in the pits on the Nascar circuit.) Enter the Viair 88P – GAME CHANGER! This pump is spectacular. It can fill my oversize tire in less than 2 minutes, and it’s quiet. To provide TONS of power it hooks directly to the battery when the car is running (of course I tried it without the car running…nope. Care would not start due to the battery drain.) This is one SERIOUS tire pump. Most people would never have to stress a tool the way I did the Viair 88P, and it came through like a true champion. I would unconditionally recommend this pump. It is a great value and a great tool.

Great pump with an improvement.

I've had one of these pumps for several months now and it has worked great so far. I keep it in my 4Runner for off-roading trips and I run 33" tires. I air down to something like 18-20 psi when driving sand or trails and use this pump to air back up to 36 psi. This pump does a good job and it's fairly quick. It ends up getting fairly hot by the time I'm done but it still gets it done in a reasonable amount of time. Takes me something like 15 minutes to air up all four tires. I am a firm believer in 2 is 1 and 1 is none so I bought a second pump as a backup in case I end up with a failure on a trail somewhere. The new pump came with a nice carry bag. I came up with a dewalt bag for the first one but this new carry bag is more compact and a good addition to the packaging. I have read a few reviews from people about these things being DOA and not finding out until they were in a bind and needed it. ALWAYS test a piece of equipment like this that you may need in an emergency when you first get it and put it through it's intended use to see if it's going to work and get things done. I air up my tires in my driveway with these when I get them to make sure everything is good to go and so far no problems.

A Great Value in a Small Package

After purchasing 3-4 cigarette lighter plug in compressors and finding them totally inadequate for airing up larger tires, I started looking at on board and portable 12V air compressors. I have a 5 hp 220v compressor in the shop so I just needed this for airing up tires after 4 wheeling or helping someone out with a flat. I read reviews and priced compressors ranging from $800 down to $40. I kept seeing reviews and people were claiming the Viair 88P was the best value on the market. For $58 I figured I couldn't go wrong. I received the product two days later and went out to the shop to unbox and test the compressor. I was impressed with the design and materials used in this compressor. The hose is heavier than I expected and the brass screw on fitting provides a positive seal with the valve stem, prevents leakage and eliminates the need to hold the chuck on the valve stem. The alligator clips are well constructed and provided a solid electrical connection. The electrical leads are long enough to reach from the battery on my passenger side to the compressor sitting on the floor next to the driver's side tire. My Jeep Rubicon has 275/75R/17 tires and I run them on the road at 36 psi. I used an accurate tire gauge to drain the driver's side tire down to 20 psi. I hooked up the Viair 88P and the gauge on the compressor read 22 psi. With the engine off I timed the compressor inflating the tire up to 40 psi on the 88P gauge. I wanted to go a few pounds past 35 psi. The first cycle, from 22 psi to 40 psi with the engine off took only 1 minute 28 seconds. I unhooked the compressor and checked the pressure with my good tire gauge and found the tire was reading 38 psi. The compressor was warm but not hot. I was able to place my hand on the top of the metal cylinder head without getting burned. The wiring and alligator clips were cool to the touch. I was so impressed with the first test that I repeated the whole process again, The second run took 1 minute and 29 seconds. The noise level was lower than I expected and there was very little vibration from the compressor. The only negative I noticed was that the work / power indicator light is on the back of the unit and the built in gauge is on the top. I haven't used this at night, but I think it would be difficult to read the gauge without a flashlight. Other reviewers mentioned to hold on to the factory shipping box for storage since the compressor doesn't come with a carry case. I looked around the shop and found a small heavy plastic "dry box" for transporting and storing ammunition. I put a bundle of shop rags in the bottom to cushion the compressor and the coiled hose and electrical cord slid right in along side the compressor. I placed another bundle of shop rags on top of the compressor. The top of the "dry box" has storage compartments so I put in a complete tire plug kit, some spare plugs, two spare valve stems, a couple tire pressure gauges, a small Mag Lite flashlight a a couple spare AA batteries for the light. This whole kit only weighs about 4 pounds and takes up very little room in the storage area behind my rear seat. Now I'm waiting for my next off road trip where I drop all 4 tires down to 15 psi. I want to see how long it takes to re-inflate all 4 tires back to 35 psi and if I can air up all 4 tires without overheating the compressor or exceeding the 45% duty cycle. I think unhooking the compressor, checking the pressure and moving the unit to the next tire will probably be enough time to allow the unit to cool before the next inflation. Don't let the small size or the amazingly low cost of this unit keep you from considering it.

Excellent Air Compressor

This is an excellent air compressor. Better than what you may need. This air compressor is a great product. It is probably better than what you may need. But as the saying goes, it never hurts to buy something better than what you need. You will never regret buying quality. I keep this air compressor in the trunk of my Honda Accord. I chose this model because it has alligator clips that connect directly to the battery rather than the cigarette lighter socket. Now, my Honda has small tires, 205s. I suspect the smaller models, the kind that plugs into your car's cigarette lighter socket, will be powerful enough to inflate my tires. But I chose this model because I also have a sport-utility that has bigger tires. This air compressor is powerful enough to inflate large tires with ease. To get this level of performance, it is necessary for the compressor to have a powerful motor. This powerful motor draws a lot of current. More current than the typical lighter socket can provide. Enough to blow the fuse on a typical lighter socket. That is why the more power air compressors connect directly to the car battery with alligator clips. Be careful when connecting this air compressor to your battery. Concentrate on the task. You do not want to mix up the polarity. Also, if your car has a small displacement four cylinder engine, your battery will be pretty wimpy. So keep your engine running while you operate the compressor, otherwise you might run down your small battery. All of this should tell you that this air compressor is not for everybody. These types of air compressors, the ones that connect directly to the battery terminals, are for those who know something about cars and batteries. You do not want to mix up the polarity when connecting. If you know nothing about cars, this compressor is not for you. In that case, get a smaller compressor that plugs to the cigarette lighter socket because you cannot mistake the polarity that way. It will be safer for somebody who is not a car person. But know that your socket driven air compressor is not going to inflate your tires as fast and as easily as this unit. There is always a trade off. Speaking of trade offs, I chose this model over a competing model that has a coiled hose. This unit comes with an uncoiled hose. It is more flexible than the type that comes coiled like a spring. This unit, with its uncoiled air hose, is harder to store but it is easier to use during a stressful emergency situation. Yes, you will have to find a way to pack the hose neatly. But to me, it is better to put up with hassle while you're at your driveway packing the car rather than at the side of the road with a flat tire. So while the coiled variety packs easily and neatly, that coiled hose will fight you when you want to stretch it from the compressor to your tire. And that will happen at the most inconvenient time at the worst location. A model with a coiled hose is neater and packs better, so it is not necessarily a deal breaker. You just have to know your own situation. If you have a small vehicle and are short on space, sure, get a model with a springy, coiled hose. Just know the trade offs, because that springy coil will be harder for you when it comes time to actually use the compressor. This unit comes in a nice box, but it does not come with a case. That should not be a deal breaker because it is easy to buy a cheap bag. Either keep it in its own box in your trunk or buy a small kit bag. I recommend that you keep all of the parts in one place because you do not want to be looking for parts during an emergency. Do what you can now to make sure that you do not add to your stress level during a road emergency. Highly recommended. This is an excellent air compressor for those who know cars. The unit feels like it is of good quality and the performance is very good. The air hose is easy to use. The alligator clips are sturdy enough, though I would want them sturdier.

Can get to 60 PSI

I was trying to inflate my 5th wheel tires that are LT235/85R16 and require 80PSI for load range E. They were measuring 72 pounds on my air gauge. When I tried to get them up to 80, the pump could not do it. As a matter of fact the tires backfed the compressor and I ended up with about 65 PSI after 1/2 hour of trying different ways to get the compressor to work up to its rated PSI. I tried everything, shorter leads to battery, thicker gauge to battery , shut down for 10 minutes till cool. Nope would not fill up to 80 PSI. But don't feel bad, the gas station pumps would not do it either. I think I can trust it to get my F250 tires up to 60 but not much over it. EDIT: November 19th, 2014. On November 10th, 2014 at 9:00 AM EST I sent an email to Viair Tech Support complaining that the pump will not perform as stated on their website. It was not the nicest email ever written either. At 2:05 PM I had an answer to my email asking for a copy of the receipt to start the warranty process. I was issued an RMA number at 2:14 PM and promptly sent the unit to Viair via FedEx. I was told it would take 10 business days to be looked at and repaired. I asked if there was any way I could get it back before November 26th. I got a response at 2:49 PM saying that they would keep an out for the pump and try to get it pushed to the head of the line. When I checked the tracking number to see if they had received the pump and asked them if they had, I was told they were already looking at it. Turns out an O ring in the air chuck had come out and they found the wiring to be loose so they were going to repair that. I HAVE HAD NOTHING BUT SUPERIOR SERVICE FROM VIAIR. After my initial dissatisfaction I would wholeheartedly recommend this company to anybody. I will update the comments when i get the pump back from Viair. EDIT: November 26th, 2014 - I received the pump and extension cord on Tuesday morning the 25th of November, one day earlier than needed! Yay! Viair!!! On Tuesday night I setup the connection from my battery through Anderson SB175 connectors so I could easily 'clip' the 88p into the battery WITHOUT modifying the wiring on the pump. Wednesday after work we drove over to pickup our 5th wheel and to inflate the 4 tires from a low of 64 PSI to a high of 71 PSI. All the tires should be at 80 PSI to preserve the load rating for my rig. I hooked up the pump to my connectors, screwed on to the tire valve, turned on the engine and then turned on the pump. After about 3 to 4 minutes the tire was at 80 PSI, up from 70 PSI. IT WORKED! I went around and filled up the rest of the trailer tires and they all filled up to 80 PSI in a matter of 3 to 4 minutes. I would let the pump run for 2 minutes and then shut it down for 1 minute. It worked great. Thanks for all your help and understanding. It is refreshing to find a company that makes a good or great product but is also responsive and stands behind the product. I have updated my rating from 3 stars to 5 stars.

Great value, great operation

10' power cord with a 16' very good air hose, not the cheap plastic hoses on so many pumps. The straight screw-on brass chuck is so much better than a clamp-on for surety of connection. This is unquestionably the sweet spot in the Viair lineup. Good bump in output for not much more than the 70P, and not as dramatic a step down in output from the beasts of the Viair lineup as ultimate specs would indicate. The headline specs are at 0 psi, which would would a completely flat tire. For most of us, that isn't in the cards. We air up from time to time when low, going from 20 to 30 or 25 to 30. To wit... Outputs at 20 psi with 12/17 prices (car tire pressures commonly are 28 to 35, so figure 20 would be a low-ish starting point)--- 70P: 0.92 cfm, $30 (30% less output than 88P, for 30% fewer $) 88P: 1.34 cfm, $44 300P: 1.76 cfm, $131 (31% more output than 88P, for 3x the $) 400P: 1.98 cfm, $169 (50% more output than 88P, for 4x the $) For heavy duty use, where the duty cycle comes more into play, then this may not cut it. This is rated at 25 minutes of operation, with a 35 min cool down. I inflate 4 35" tires in a Jeep from 15 to 28 psi in just about that amount of time.

Solid, easy to use unit

This seems to be a pretty solidly built unit. Operation is straight-forward - all you have to do is hook it up to the car's battery, attach the hose to tire, turn car on, and turn on the compressor. It only took about 10-15 seconds to go from 25 PSI to 30 PSI in a sedan tire (205/65R15). This is plenty fast for a sedan, but the CFM rating might be too low for pickup trucks. I'll try to update this when I try filling up a truck. One minor con is that none of the parts are serviceable so if the hose breaks, you just have to get a new unit. The box that it ships in is very small, so it forces the hose to bend at a right angle, creating unnecessary wear on the hose. Since it doesn't come with a carry case, I'm sure a lot of people will just shove everything back in the original box, wearing out the hose prematurely. I don't know if this will make a huge difference on the life of the product, but to be safe, I'd recommend cutting the box to allow the hose some more wiggle room.

Solid Build - Works Well

I just purchased this Viair based on reviews and reviewing the company's website, along with a good solid 3 days of reviewing many compressors. The reviews on Amazon helped make my decision. I live chatted with Viair online and they are very responsive. First off, as I know someone probably has a headache from trying to make choices and wondering which model for what tire. The 88P model is ideal for tires up to 31" (up to the larger tires seen on trucks, off road, etc.). The lower models numbers like the 85 or 87 are for cars, minivans and the like. Now, if you want up to 31" allowance because you might have a trailer, ATV, then by all means, go for the 88 or 89 models; they are all the same size units. 88P and up have the battery connectors vs. cig lighter plug in. Yet, I've read you can get the cig lighter / 120V cig outlet adapter for this model. It seems very sturdy and I tried it out on my Truck with 265/70R17 size tires. No issues. If you see my other reviews, I bought a small military bag here on Amazon to go with it. Fits great with room for the long hose and power cord. Here's the link to the bag on Amazon http://www.amazon.com/gp/product/B0143JZZWG?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00 I also purchased the Tekton 5941 Digital Tire Gauge here on Amazon. It matched the gauge on the dial gauge of the compressor when I tried them. So, I would recommend the Viair. Great size, portable and durable.

Blows away any cigarette lighter compressor!

This pump is amazing. I was searching for a quality compressor, this one definitely fits the bill. I have had this compressor for a little over a year, I use this compressor a few times a month. I am continually amazed by the performance of this compressor. It fills up tires unbelievably fast! The whole unit is very well made. The hose and alligator clips are high quality, the fitting to connect to the car is very simple and effective, it just threads right on with no leaks. The compressor has a high duty cycle, meaning that you can fill a tire completely without stopping the compressor to let it cool down. I've used this compressor on many cars and pickup trucks, it's always plenty long to fill all four tires with several feet of slack. It can fill trailer tires if the trailer is connected to a smaller suv. When the hose and wire leads are outstretched, they reach approx 25ft. This compressor uses a direct connection to the battery, instead of a cigarette lighter adapter. This is because of the power of the compressor. It draws too many amps to be powered by a factory cigarette lighter, you would burn the fuse every time. Mine drew 18 amps at 35 psi. While this may be less convenient, it's not possible on most cars, to get the power that this compressor provides with a cigarette lighter adapter. The pros of this compressor are: *Great power, fills tires fast *High duty cycle, can fill a very low tire without stopping the pump *Very long reach 25ft from alligator clamps to end of air line. *Range can easily be extended with use of jumper cables. *relatively quiet. *quality build, should last a long time! *built in flashlight *accurate gauge Cons of this pump are: *Heavy for its size *gets quite hot *needs direct battery connection *no case I would absolutely recommend this compressor for anyone who wants a quality compressor that should last a long time.

88p Is the way to go!! 88p vs 70p vs 85p vs 90p

70p 15% duty cycle which means you should only run it for 1.5 minutes and let it cool down for 8.5 minutes. Then you can start again. 1.27 cfm @0 ps 20 ft maximum reachi Cigarette lighter adapter Kit bag Overall it's a great little compressor but for light duty. 85p 40% duty cycle which means run for 4 minutes, then cool down for 6 minutes. 1.83cfm@0psi Fills up to 31" tires 13 ft maximum reach Cigarette lighter adapter Kit bag Overall another good compressor but you will blow fuses like there is no tomorrow unless you have a 20 amp cigarette lighter. The worst part is the reach. 13 ft iwill make it hard to reach tires for mid sized cars and up. 90p 15% duty cycle which is 1.5 minutes of. Run time and 8.5 minutes of cool down time 1.77 cfm@0psi Fills up to 31"tires 15ft maximimum reach No cigarette lighter adapter but available if your cigarette lighter uses 30 amp fuses Kit bag Overall, bad run time, bad reach for air hose, uses too much power for what it does. Worst out of them all 88p (Save the Best For Last) 45% duty cycle 4.5 minutes run time and 5.5 minutes cool down time (highest out of all of them) 1.98 cfm@0psi (awesome) more air output means less time filling up tires Fills up to 33" tires 20 ft maximum reach No cigarette lighter adapter but available and might not blow your fuse if you have a 20 amp. Not sure though because I have not tried No kit bag but go buy a cheapo from a big box store. It is probably more durable than the kit bags that come with the other kits. Overall, the best in the price range. Most powerful and it is still just as small as the others. I have a Chevy 2500hd and it fills my tires up fast. The 88p laughs at my wife's range rover sport tires. I never write reviews but I am so impressed with this thing that I had to.
