Rated 5.0 out of 5 by 6 reviewers.
Rated 5.0 out of 5.0 by Easy use Worth every dollar already used it twice and expect to use it in the future. Love the portability of it and not having to dig for change or a credit card to use at a gas station while waiting my turn for air. December 15, 2015
Rated 5.0 out of 5.0 by Very Nice Portable Compressor!!! The compressor arrived by mail very well packaged. I tested it out on my F-350's 18" tires. I lowered the air pressure of one of the front tires to 30psi. I timed the time to inflate it to 60psi. It took 4mins-18secs. I was impressed. I then topped off the other tires. The compressor only got warm and not too hot. I would highly recommend. October 14, 2015
Rated 5.0 out of 5.0 by Highly Recommend This replaced the VIAIR 90P that I've had for 3 years (which was good but underpowered for my needs). The 90P is now my backup, not that I think I'll need it. I've only used the 450P once thus far, but it aired up all 4 tires (265/70/17) from 18 to 40 PSI in about the time it historically took the 90P to do 1. It is quiet, sturdy, and didn't skip a beat on an 80F+ day in direct sunlight in an asphalt parking lot. The bag is nice, but not sure how well it will hold up to severe use -- doesn't detract from how impressive the 450P is. I may not need to install an on board system on my truck now... May 8, 2012
Rated 5.0 out of 5.0 by Great Job Home Depot I was looking for a high end compressor to use in my fifth wheel camper. I had several of the low dollar units but they were not capable of producing the higher pressures that the tires needed. I was surprised to find out that I could order this compressor thru Home Depot. The web site was very good as was the time of shipping. Thank You for satisfying my needs. February 4, 2014
Rated 5.0 out of 5.0 by Great Product Works as advertised and works well! Inflation is the fastest of any portable pump I've come across and the pressure gauge is the most accurate. Nice carrying case. December 27, 2013
Rated 5.0 out of 5.0 by Portable, quiet and powerful It takes up such a small footprint.. It's a great product that is well built October 8, 2013
