    • Fantastic for High Pressure Trailer Tires
Style: Original Portable
Ordered it to put air in my boat trailer tires, they are large 16" that run 80-90 psi, have always had trouble getting them filled, you can't get the trailer into most air hoses, and even if you do they don't have the pressure. Hooked this thing up, you turn it on, it comes up to pressure and shuts off, then squeeze the trigger to put air in and it kicks right off, was able to bring the tires up to 90 psi in just a few minutes each. Not starting from scratch, they already had just over 80 psi, but it is always that last bit to get them up to 90 that is so hard. This thing just pumped them right up, it is very quiet, doesn't vibrate around at all, just sits there and hums and away you go. It gets warm, but it wasn't excessive, just a few minutes and I could put it back in the case. I will say the case is very nice, holds the compressor and two extension hoses that are high quality, but it takes up a lot of room. Not sure how to best carry it in my truck. ... show more

    • High Quality and Flexible
Style: Original Portable
I have several VIAIR pumps. Unfortunately the last one was stolen. I believe this one will be my favorite for the following reasons. Number one is the auto shut off. Many units require that you return to the pumps to shut it off. In the past I would over fill the tire, return to the pump, shut it off and then return to the tire and reduce air to the proper pressure. Doable but extra effort. Number two is the continuous run cycle. Many units can run for 15 minutes then require a 30 minute cool down time. While maybe not important to some why risk it and have the auto thermal protection shut it down and wait 30 minutes. As an added bonus I suspect to get the continues run time the rpms on the motor have been reduced and the unit is pretty quiet. Number three the supplied air gun has a bleed off button which allows you to reduce air pressure easily if you over fill. Number four the unit comes with two hoses, the extension for dully tires and the air gun with gage so you are ready for most anything. Number five the whole package is small enough to fit under most SUV's back seat. It is high quality and not cheap like some you see in some discount stores and gives you a "get to the tire store" back up as well as avoids you having to locate a gas station with an air pump, chunk in quarters and hope it works for a simple air top off. About the only downside I can see is because the gage goes to 170 if you routinely fill passenger 32 LBS tires you may want to add a smaller scale gage for a bit more accuracy. My package also came with the screw on valve connection. Very solid but if you do a lot of tires the "flip down" one would be quicker. It is available separately. Note the hoses I got were black which I prefer. ... show more

    • Great Portable Pump- Highly Recommend
Style: Original Portable
I originally purchased one of the lower-cost portable air pumps (100psi, 10-minute runtime before overheating). I figured it would be able to handle filling one 275/60R20 pickup truck tire. I was wrong. After 10min of running, that pump went from 15psi to only 34psi with a target of 40psi. Even the airline was too hot to touch. Fail. Enter the VIAIR 450-P that arrived today. Same tire, starting at 15psi... it took the VIAIR pump just over 2 minutes to inflate the tire to 40psi. Immediately after, I filled the other three tires from 35psi+/- up to 40psi, each very quickly. The pump body never raised in temperature. The entire package seems to be good quality. I was a little worried that the coiled airlines were too rigid, but they're not. With the pump at the front of the (Crew Cab) truck and hooked to the battery (truck running), 1 airline easily reached to the rear tires. The VIAIR pump is much quieter than the my cheaper pump. The auto turn-off when you're not filling a tire is a nice feature. The air gun also has a button to release air, if you go too high. The bag has extra room for tire plugs, etc. Mine also came with 2 extra air filters for the pump. There's a few comments about having to hold the trigger while filling the tire. True, but the 450-P pumps up the tire fast enough that it really isn't an issue (for me). The air gauge is off about 1-2psi, but it's not built to comply to rigid engineering standards and regulations. It's an air gauge for the masses, and mine was very close. Except for the price, I can't knock this VIAIR pump... but I'm willing to pay for the proper tool for the job. ... show more

    • I love this Compressor
Style: Original Portable
Works amazing easy to hook up to my truck batteries and the kit as a whole is perfect for my needs. I have a large RV and six large tires that nee to be checked all the time. This compressor fills my tires to 100psi in seconds. I have had to inflate a flat tire a couple of time and the compressor just ran and ran no over heating no slowing down just smooth running. The bag it comes with is very nice canvas I have dropped it in the mud a couple of times and just hosed it off. The hose work great you can couple and uncouple with one hand " with a little practice" The gauge on the air gun was bad I called for a new one and never receive it. I use a different gauge so big deal but for the money you pay for this every piece should be primo. ... show more

    • Quality compressor for RV'ers
Style: Original Portable
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. ... show more

    • I've been needing this for SO LONG!
Style: Original Portable
Viair has been recommended to me by so many RVers! I finally broke down to get this one. My RV tires require 110 LBS of pressure (4 tires), and this will do the trick. My camper came with an "on-board" air compressor.... but it's too "sissy" to air up it's own tires! It was only intended to use for toys, bikes, pool blow-ups, etc., not the camper's tires. SO disappointing that one needs to have 2 air compressors. If there's a way, I will remove the compressor that came with the RV and use the viair only. I've already used it to help me winterize the water system. Amazing tool, amazing bag, great product! ... show more
