VIAIR 450P/45043 Automatic Portable Compressor, Tire Inflator Kit, Air Compressor for Truck, Jeep, SUV, and Car Tires, Portable Air Pump Kit, Car Accessories, 100% Duty Cycle, 150 PSI/1.80 CFM, Silver

I live in South Florida and there is not a gas station within miles of me that has a working air pump. After plugging a tire and driving for the better part of a hour to find an air pump that is not out of service, or in service but still broken, or wouldn't steal my quarters, I decided to get my own. I've gone through a few inexpensive Black & Decker Power Stations but they would never fill-up the entire tire, they were extremely loud, and broke frequently. After doing some research I have finally found Nirvanna. Some of the things that I expected but turned-out better than I hoped: 1. Quiet. I knew people said this thing was quiet but I was VERY impressed when I turned it on the first time. Perhaps I have never heard a true quiet compressor since all the ones I used sound like a Mac truck engine but this one is more than acceptable. I can use it in the middle of the night in my condo's parking lot without the slightest worry of waking my cranky neighbors. Plus when you release the trigger it shuts off. I like that. 2. Lots of power. This fills tires up fast! I do not have experience in filling light trucks or SUV's yet but from the speed it fills my bicycle, car, and motorcycle, I have a good idea that a larger vehicle would not be a problem for this work horse. Oh, and filling smaller things are easy too, just squeeze the trigger in spurts. 3. 100% Duty Free. Not common for a portable compressor. I hated using a compressor then having to go away for 15 minutes then coming back to continue filling one tire... it would take forever for me to fill four. While at work I filled-up all four of my tires, two of them were real low (22psi out of 44psi). My co-workers saw me using it and asked if he could use it for his as well. Off my car onto his and his were under 20psi's and we had his entire car done in a few short minutes. 4. Nice tote bag. It fits and protects everything you need. 5. Great reach! No more dragging a heavy compressor from wheel to wheel, now you just leave it in one spot and the super long coiled cord does the rest. 6. I like how you can lock the air chuck onto the valve. Many of the gas stations have this stupid system where you have to fight with it and constantly apply pressure to the valve as air leaks everywhere. The air chuck is not too big so it fits inside small hubcaps fairly easily, and there are no leaks! 7. It has an simple pressure release valve right on the trigger. It doesn't happen so much with cars but when I overfill my bicycle a little too much I can reduce the pressure with a push of a button and without having to remove the air chuck from the bike. 8. Nice large PSI gauge display. 9. Zero vibration! The compressor stays put the entire time. Some of the things I expected as a drawback and kind of still are: 1. It's heavy. I'm a big strapping man and I do not have any trouble with it but some folks will find this to be a deal breaker. Especially if you have a bad back or you are elderly. 2. The trigger should have a lock (like gas pumps) where you can let go for a while. You will need to hold that trigger the entire time, and despite filling-up the tires fast if you have bad knees this could be an issue. I find the trigger easy to grip and compress but a simple lock feature would have been nice. 3. Not the most convenient. It is not too bad but it is not just turn on and go. You will need to connect it to the car battery, then you need to connect the hose and the trigger. The hose is snap in so I find I am getting this done quicker each time I use it but it is more time consuming than a battery operated one. 4. I wish the PSI gauge would light-up for night reading. Every compressor I ever owned had this feature, from the real tiny Slime ones to the larger Black & Deckers, why not the 450P? Overall you are paying a premium price for a premium product. I am glad I went with the 100% Duty Cycle version as I feel it is worth the extra bucks. I hope this helps

This is not the fastest out there, but it works very well. 100 percent duty cycle. Very quiet and so little vibration, so much so I was pleasantly surprised. All my other 12v compressors have been noisy, and shake like crazy. The carry bag is nice, the hose and all the accessories are well thought out. One of the situations where you get what you pay for, and I have grown tired of paying for junk. This should last a long time. Happy customer for sure.

I finally got to try this new compressor today and I am really pleased with it. With stock size tires on my Wrangler, from taking this compressor and hose out of the bag to hitting the road again was less than 15 minutes. I was airing up from 23 psi to 38 psi. I didn't use the included tire fill guage since I have a digital fill guage, but I am sure it will work fine, if not as precise as a digital version. The automatic shut off feature prevents the compressor from exceeding a safe pressure for the line, and will automatically fill air tanks in case you want to use it with one. In operation it is very, very quiet compared to cheap 12v compressors that come in tire repair kits and emergency road kits. It also has very mild vibration in use. I set it on my front bumper to inflate the front tires and it didn't budge thanks to the dust tray and good vibration dampening. I have had cheap compressors jumping and scooting all over the place when filling tires. They have their place for emergency use but if you are going to be airing up and down a few times a day on multiple trails, they are pretty inconvenient. It does get hot during use (all compressors do, because when you compress a gas, heat is released) but this model has a 100% duty cycle so no need to let it rest between tires. Anyhow I am a big fan of this compressor. It has everything you need for inflating tires quickly when the dirt turns back into pavement in one kit. Also nice is since it's portable you can move it to a new vehicle without needing to unbolt anything. I love it when a product does exactly what it is advertised to do, and this compressor does. Fills tires fast and has plenty of power to spare for other uses. I think I might get a small tank to go with it to be able to operate air tools and fill tires even faster.

So far this and my other Viair 88 have been excellent products. This one has the very handy feature of shutting off when you aren't actively pumping air. I can't overemphasize how nice that is. The bag is a little thin but it is holding up fine. I'd prefer a little heavier material. There is enough room in the bag to add a patch kit and other small items. Being 100% duty cycle means it will just keep going and going. I chose that over a faster fill but 33% duty cycle because I didn't want to be worrying about or managing cool off periods. A false economy to a faster fill. The faster models also take more amperage, but that isn't a big deal. The hose is really nice that it stretches to all 4 corners of a full-size truck. Overall, very happy with this. I air down from about 38 to 25 psi for mixed offroading and lower for specific needs. This airs up after with no problems at all.

I was able to bring my rv Tire from 5.6 psi to 101 in 9 minutes. For a small portable unit this is very acceptable, and to be 12v therefor usable on the roadside makes it a winner.
