I should have bought an Air Compressor years ago

Love this machine. Simple to operate, simple to maintain. Has plenty of power for using an air gun for cleaning, or adding air via tire inflator tool on all my cars, children's bikes, wagons, wheelbarrows, etc. I use this tool monthly.

Only Cons:
- Heavy - not designed for quick portability (it's a solid 60-80 lbs). You can throw out your back if you're not careful.
- Loud - I don't know a single air compressor that isn't loud, but this isn't one of the quieter ones, but it's also not one of the smallest. With the garage door open, the sound can broadcast outside fine. But if your garage door is closed, you'll probably want ear protection for lengthy jobs.
- The power requirements at the wall outlet where this plugs into has tripped my circuit breakers multiple times. Don't have too many other items plugged into the same outlet or you will trip the breakers.
- Would not recommend this if you're doing serious air tool work i.e. air powered metal grinding tool for an automotive restoration. Although this will work, you'll probably want something with a bit more power to minimize cycling time.

Aside from that, very pleased with the power and the speed of air cycling times to get the air reservoir pumped back up to high pressure.

i used it to do a quick fix on my old mini compressor... it was easy to wire onto it and worked. i would suggest replacing the fuse in it with a higher fuse if using it for an air pump though.

Nice air compressor, but you can purchase at Home Depot of $19.

I've been through 3 switches from different vendors and they all leaked air from the start. So I was skeptical as to buy another switch or a new compressor. I'm glad I took the chance. So far no leaks and my compressor actually reaches 120psi like it used to.

This compressor is perfect for the home handyman or for those of us that have a need for portable compressed air.  The size is nice, if maybe just a bit loud.  Right off the bat the compressor would not hold air pressure.  With a full charge it would leak all the way down to empty in about 2 hours.  Turned out it was due to several loose fittings and a leaking drain valve.  So I managed to slow the leak with those repairs.  It then sat in storage for about a year while I was moving (warranty expired in this time).  Low and behold the leak down problem returned although not as bad, but to add insult to injury, the first time I try to use it after being stored, the pressure regulator failed.  After I took it apart, I found out that the valve spring beneath the pressure regulator knob is held in place by a flimsy plastic flange, so it was destined to fail.  To fix the problem I had to buy an entire new manifold assembly (not a bad thing as Porter cable redesigned the pressure regulator on newer compressors and manifold assemblies eliminating this weakness).  The new manifold was easy to install.  So if you're considering this compressor, buy it new and make sure it has the newer style manifold.  On the new manifold the two pressure gauges are different sizes and very close together.  If the gauges are the same size and about an inch or more apart, be prepared to spend $44 on a new manifold.  Even after all the trouble, mine still leaks and now will only get about 135-140 psi max.  Nail guns are great!  No problems with those and I love them!

You would be lucky to find a refurbished compressor for $350. This NEW Universal Air Condish compressor bolts on perfectly, connects beautifully and works like it should. One knock is the instructions that came with the part. No reference to what kind of compressor oil to use with this compressor. I had to search the webs and found "RL488 or equivalent." Translation: use PAG 150 compressor oil. You're welcome. Also, be sure to drain the compressor completely since it arrives with oil in it. Replace the oil and then close it up prior to installation. This might be obvious to most, but I would like you to prevent the eventual oil compressor in the eye trick if at all possible if your a bit logically challenged like me.

I have gotten a good bit of use out of this compressor. I keep it in one of those military style tool bags, and it is always ready to go whenever I have a low tire. It also works a whole lot better than the cigarette plug cheapy compressors do and holds up better, so it is rugged enough to keep behind the seat of my old work truck!

Wow.  2 years ago I received a cheapo air compressor as a gift.  It seized up, not surprising.  I paid a little extra for the DeWALT, but I have to say it is very well made, quiet, and does a great job.

Compared to the cheaper compressors I've had, this one is much Quieter, much Quicker, and overall much better Quality.  The hose (8') and cord is more than long enough for most vehicles.  The brass screw-on hose works easy.  Definitely recommend spend the extra money and don't go cheap.  The only recommendation for improvement would be for the the gauge to be a more realistic scale:  Goes up to 120 PSI so it is hard to tell when the needle is on 32 psi.

This is the best little air compressor I've ever had.  The auto-shut off feature works great.  I just wish the hose and power cord were a little longer.  The 12 VDC operation cord is plenty long but the others are only like 2 feet...  Still I recommend it highly.  Use an extension cord and put it next to the tire and your good.

Iv have had this slime air compressor for more then 6 years now and It is still kicken. I orginally purchased it at lows or home depot. I use it often for the three vehciles and kids bikes. I recently purchased a Jeep wrangler and am now going to Upgrade to an ARB twin Air Compressor due to the fact that I hate that this one is just fumbling around the floor board all the time. I will now retire this one in the family car for an emergency.

I originally  purchased one of those gift item compressors that are all over the department stores during the holidays that retails for nearly twice the price of this item.  All I ever managed to do with that one was let air out of my tires, it never increased the air pressure.  So I took it back in disgust and went straight to Amazon and found this for half the price.  I did quite a bit of research after finding this unit and found much better performing compressors but ultimately came back to this item for one key reason.  The better performing air compressors require higher amperage and therefore have a tendency to blow fuses in regular capacity automobiles.  So after checking my owner's manual I determined that this AAA compressor was a perfect fit for my Toyota at 10.5 amps.  No blown fuses.  The capacity is not great but it gets the job done eventually.  Unless you have a heavy duty truck or something, you should avoid the better rated compressors unless you want to replace fuses in your car every time you use it.  The prices of this compressor is great so you get good value for your money at $17.  The limitation is mostly with the amperage capacity of my car but I still can't rate it 5 stars.  However, I do recommend you have this in every car in your personal fleet.

If you're anything like me, stopping at the gas station to put air in your tires is a pain especially when you think your tires are low but your husband is telling you your fine but the potholes say other wise... I had to get a portable air compressor, I've had my share of tire trouble to the point that I'm a paranoid driver. This compressor is able to fill my tires (35psi) and the plug in goes in the cigarette lighter outlet. It works best with the engine on although I was still able to air my tires without it on, but you can tell it's struggling. I definitely recommend!!

I am more than happy with my purchase.  I needed to replace an old compressor and this fit the bill.  I held off giving the full 5 stars as it's a little noisy but it fills the smallish tank rapidly and most important, I'm back in action.

I am probably premature on my review as I have only had this compressor a couple weeks and used it for the first time today.  I have a small camper and it is hard to find a gas station where you can get to the air hose with the camper.  So I decided it was time for a portable compressor.  This one and other models by this manufacturer were recommended on the camper forum I frequent.

My camper was just de-winterized and I took the battery (car-type) over to re-install in the camper.  Before putting it in the battery box, I carried it around the camper with the compressor while airing up the tires including the spare.  I have a reasonable quality air gauge that I used to check the accuracy of the gauge on the compressor and they both agree with each other.  I aired the trailer tires up from 45 to 50 PSI in 30 seconds, more or less.  That was the first surprise.  The second surprise was how quiet it is.  I expected it to be loud and obnoxious but it wasn't even close.  Imagine how loud you think it is and cut that in half.  So there should be no problem using this at the campground to air up the trailer, truck bicycles and anything else.

Only time will tell how well it holds up, but it exceeds expectations for now.

So I have carried this air compressor in my camper all summer so far and it was worth every penny.  I have used it to fill the camper tires, the truck tires and our bicycle tires.  It fills them all quickly and easily. The built-in gauge appears to be accurate as well.  I hope to get many years of use out it.

I read alot of reviews before buying this and almost went with the lesser model (70P). However, I didn't want to mess with blowing fuses so I got this model that connects directly to the battery. It could not be more simple to hook this thing up! It is easy to use and pumps quite fast (no idea how long from flat to full as I only had to top off at most 8PSI). The first thing that struck me when I opened the box is how solid this compressor it feels. Very little plastic and lots of high-quality metal construction. I was thoroughly impressed. Overall, I have no complaints whatsoever with this pump. Cords are extra long to reach all the tires on the vehicle ('96 Buick Lesabre) with feet to spare. Buy this compressor and you will not be disappointed. In fact, you will probably be a bit spoiled and will not want to ever go back to the wimpy plasticy compressors.

Great item I just wished I would have known about this item years ago could have saved lots of money
