Matt Savage VIAIR 450P-RV Automatic Portable Compressor Kit (12V, CE, 100% Duty, 150 PSI)

When we bought our Ford F-350 Dually and a fifth wheel trailer, I bought a CAD$80 (~USD$60) dual 12/120v air tire inflator. The first time we needed to use it, we found out how slow it was. We needed to raise the air pressure in our four big trailer tires from about 90 psi to 110 psi, with one tire at just 57 psi. It took nearly a half hour to do this, and was so slow that I settled for just 100psi--our friends were waiting for us to finish before we left the meeting point and headed on our way. I was determined not to repeat that frustrating experience. My next purchase was a much faster 12v tire inflator for about CAD$150 (~USD$112). It was much faster and certainly addressed the frustration problem. However, after about an hour's total use, the plastic part that clamps on the valve stem blew off the end of its hose. I was able to get a free replacement under warranty, but after a mere half-hour of use, that one started blowing its fuse every time I used it, rendering it useless. So, I decided that I had to find one that was highly rated and would last. After my experiences with these other ones, I was willing to pay for a good quality tire inflator. Well, the Viair 450P-RV is exactly what I was looking for. It comes with all the attachments you need. It has a long coiled hose and a second extension coiled hose so that you can have the compressor near the front of the truck or trailer to reach the battery in either one yet still be able to reach back to the tires. I was even able to use the battery in my truck and reach all the way back to the trailer tires on our 36-foot fifth wheel. Overall, we're very happy with it. One caveat--we've only got about an hour's use on it so far. From all the reports I've read, it's very reliable so I'm not worried about that at all. However, I can't personally testify to its longevity. A great product, and I really wish we'd bought it much earlier!

This Compressor works great on our TV Trailer Tires that require 110 psi, no problem for this pump… Plenty of air line.. Love it!!

We had been carrying around one of the standard cannister style compressors in our RV for a couple of years. It was 150 psi max, but as most people know, filling the 110 psi+ tires on an RV is near impossible. So I invested in the Viair 45053 RV edition. It was pricey, but I thought maybe it would make life easier. And it did. The unit weighs less and is smaller than the compressor I was carrying around before. It also comes in a bag with pockets for the attachments and hoses, so everything is more consolidated and compact while in storage. Things to know before buying: * This does not plug into a normal wall outlet. It attaches to your vehicle's battery. * This unit does not have a cannister (in the normal sense) and operates oil free (keeps it lightweight and small). * Filling a 110 psi tire can take a while, depending on how deflated the tire is. It's not a fast process. Don't get impatient. * You'll be a lot happier if you can use the screw-on adapter to fill the tires because it will save your hands. Take advantage of it when you can. Honestly, I was expecting to be disappointed simply because so much stuff I buy for the RV on here turns out to be 'less than optimal'. :-) But I am not disappointed. I've used this item to inflate the RV tires (all 6) and even our e-bike tires. I'm hoping it's the last compressor we need for years to come.

Great product, arrived fast price point a little high.
