The VIAIR 450P Automatic Function Portable Air Compressor is the only 100-percent duty cycle portable compressor on the market, and can run for extended periods of time depending on your environment. Its automatic pressure regulation system is designed to maintain an internal tank pressure of 145 PSI by cycling power to the compressor motor. This compressor is also equipped with a detachable gas-station-style inflation gun, which allows you to easily fill tires with a simple squeeze of the handle. This inflation gun can also show current tire pressure, so you don't need an additional pressure gauge.
From the manufacturer
VIAIR offers the most comprehensive line of fractional horsepower DC oil-less air compressors and air accessories for on-road, off-road, and industrial markets. Since 1998 our quality engineered compressors have become the industry standard for automotive aftermarket applications worldwide.
Heavy Duty Compressors for Tire Inflation
VIAIR's heavy duty portable tire inflators can be used on any vehicle with a 12v battery source and are designed for tires ranging from 33" to 42" diameter.
These compressors are suitable for both on-road and off-road vehicles.
VIAIR’s Automatic Tire Inflatiors make tire filling simple! While most portable air compressors must be turned off between tire fills and checking tire pressure, the Automatic compressors only operate while the trigger on the inflation gun is pulled. This will certainly save you much needed time, making the overall process of filling your tires seem effortless.
For those in the off-road segment, airing down tires allows for better traction while off-roading. Once your tires need to get back to their normal pressures, you simply hook the compressor up to your battery, and fill them to the recommended on-road pressure your vehicle suggests.
For those in the on-road segment, proper tire inflation is very important because it helps keep your tires lasting longer, it's better for gas mileage, and overall makes for a better ride while keeping you safe on the road.

Bought this for use with my 4WD truck and jeep for airing up my tires. Did a ton of research and decided on the Viair 450P but still wasn't sure what I was going to think of this unit. After getting it and some use I am actually really impressed with the quality of everything that comes with the compressor. The air gun and pressure gauge are well made and seem heavy duty. The hose and clamp on air chuck are both nice - hose is made of nice rubber and the air chuck is heavy cast metal vs stamped steel. The long curly air hose is NOT the typical cheap plastic hose (usually yellow and cracks or shatters after any small amount of time in the sun). It is rubber coated with a woven/braided line. Very flexible and also fits nice into the front bag pocket. The bag seems nice and has plenty of room for everything. Material is a little thinner than I would prefer but zippers are large and smooth and bag has plenty of room for everything. The compressor itself is solid and well put together. Nice handle and base. Fairly quiet in my opinion when running. It pumps up one of my trucks 35x10.5 inch 10ply/E-Load tires from 30psi to 70psi in about 5 minutes. The auto shut-off feature is great when you are switching to another tire or the other side of the vehicle, as the compressor quits pumping - and generating heat. The 450P kit comes with extra air intake filters and some different ends for the air gun (like a needle for pumping up a basketball). The model 450 compressor is rated at a 100% duty cycle, meaning it is built to be continuously run for up to an hour. Other Viair models that have a higher air/CFM output rating, like the 400 & 440, are rated at a 33% duty cycle, meaning they can run for about 20 minutes before needing to be shut off to cool down - see Viair's website for the specs. So depending on your intended use, the 400 or 440 may be a better choice due to the faster fill rates. For me, the benefit of the 100% duty cycle is I can fill my tires (that require a higher PSI) PLUS fill my trail buddy's tires as well, and NOT exceed the rated run time. Overall very happy with this product.
Quick update. Can't say enough about this little air compressor. It does great on my 35×12.5r17. Now for a real test. I got home with my 07 379exh peterbilt, and had a flat tire. This is a 295/75r22.5 that takes 110 psi. And in about 20 minutes it went from 0 psi to 85 psi. Is it the fastest way to air one up? Nope, but when it is all you habe at home it is great that it can do the job.
My only complaints: 1.) Although the alligator clamps are very durable and maintain a tight squeeze, they're a bit small and seem to want to slip off the battery terminals. 2.) on/off switch is flimsy. 3.) Biggest complaint: there is no mechanism to keep the inflation gun in the squeezed position; you have to crouch next to your tire and hold the trigger the entire time. It seems petty, but for the money I paid, the gun should have this feature.
Bottom line: this is overall a great compressor that I'd recommend if you don't mind spending a little extra money.

I HAVE PAY FOR A NEW UNIT NOT DAMMAGE!
Good hose length to get to the trailer tires.
Had cheaper models that overheated. This unit is part of the essential equipment for all trips out of town.
I docked a star because the zipper on the bag is really low quality, it looks big an tough but it's made of really cheap plastic. Honestly, it's the worst zipper I've ever seen, it will definitely break very easily unless used very carefully.
Cables do get stiff in the cold so keep it inside your truck.
It's not made cheap, I'm happy with it
