    • Compact and powerful
Style: Air Compressor Kit
This is a serious work horse. My hotdog compressor is rated for 150psi but can't inflate my 110psi fifth wheel tires! This little unit brought all four tires up to the recommended pressure in about ten minutes. It runs on 12volt power with big clamps directly to the battery so it works anywhere. It clamps onto the valve stem so you don't need bionic fingers to hold it on. It does get hot, but not dangerously. Highly recommend this for RV travel and nearly unlimited other uses. ... show more

    • Top Notch Quality
Style: Air Compressor Kit
I purchased this air compressor to air up my Jeep 33” tires after going off-road. The Viair compressor is relatively quiet and fill speed is very good. I wanted to go with a slightly stronger (faster) model, but I needed to stay under 40 amp draw. The bag, hose and fill is top quality - much nicer than the off brand units. Highly recommend. ... show more

    • Blow it up
Style: Air Compressor Kit
Perfect for my 33” and it way quieter than I was expecting and much faster. It’s not the fastest but definitely gets the job done in a reasonable amount of time.

    • Strong compressor, good for off road and piece of mind
Style: Air Compressor Kit
A real life saver. I regularly go very far into the mountains, behind locking gates on permitted land. The kind of places that you are highly unlikely to see another person for weeks or months. Remote places that would take days to hike out to get cel reception. This air compressor has saved me on multiple occasions. It was a powerful enough to quickly inflate tires on a FWD vehicle. You still need a good tire patch kit on hand. The downsides are the hose is not long enough to easily reach the rear tire opposite side from your battery. And, the psi gauge doesn’t work while you’re inflating. That is annoying. The compressor is not too heavy. Fits in the back of your vehicle. Comes in a handy storage bag. Looks well made and sturdy. ... show more

    • Perfect for offroading
Style: Air Compressor Kit
This works great. I have 33" tires and I'm able to air up from 15psi to 35psi in less than 10 min for all 4 tires. And that is just using 1 hose. If I had a 4 hose setup, I think it could handle that also. Bat is a bit larger than all the gear which allows for added extras so you keep all the air stuff together. A great buy ... show more

    • Buy Cheap, Buy Twice
Style: Air Compressor Kit
I regularly go off-roading in California's deserts and wanted a reliable way to add pressure to my tires when returning to the pavement, and to reinflate tires after a repair. I purchased this compressor in 2010 after my cheap, barely adequate $25 "tire inflator" from a department store chain stopped working. I have had zero problems with my Viair. Uses: In addition to the uses above, I use the compressor every couple of weeks to top up one of my tires that has a slow leak. I just used it to quickly top up the tires on my wife's van. I have also used it to inflate my kid's wading pool via an extra attachment that came with our bicycle pump. Pros: Well made and reliable Easy to connect to the red battery terminal and ground via the alligator clips Positive latching on to the tire stem Pretty fast inflating of even large tires Consistent readings from the integral tire gauge Packs up into a relatively small package that can stay in any vehicle 24/7 Carrying case is handy and makes storage easy Cons: Gets warm after a couple of tires and needs to cool off before packing it up The coiled hose offers a lot of resistance, making reaching the last tire a struggle Getting the compressor back into its case takes a little work Bottom line: Good piece of gear at a fair price point. An additional bonus is that I can forever skip the quarter-fed, nasty gas station air stations that seems to pump as much moisture into my tires as air. ... show more

    • Good quality kit
Style: Air Compressor Kit
I bought this portable pump about 3 years ago for fixing flats on the road. I keep it stowed in my truck under the back seat. It has worked very well. Its convenient enough that I use it at home to maintain tire pressure in all of our vehicles. Its been a reliable tool with good build quality. Good to know: The pump gets hot for a bit, so you need to let it cool before re-stowing it. If you have a lifted truck the power cables might not allow the pump to reach the ground. The pressure gauge only reads when the unit is off. That makes for a little back and forth when you want to check progress. Not hard to let out excess pressure, though. ... show more

    • Great tire inflator. Quiet, fast, small and easy to pack.
Style: Air Compressor Kit
I was wanting a better quality tire inflator to carry in my Travel Trailer. It had to easily inflate my trailer tires that are rated for 80psig. I read over the reviews of several inflators and decided on the 300P. Put it to the test yesterday. I am very pleased. Had no problem handling the 80psi tires. Pumped one that was at 70 psi up to 80 in about 65 seconds. The battery clips are plenty large enough to grab onto a battery post connector. My trailer batteries are located front underside of my 34 foot 5th wheel center compartment. With electric wire and coil air hose, I reached tires with no excessive stretching. The air hose to valve stem clamp is very good and tight. No air loss and would be much easier than the screw on fittings others come with. This unit also has the "Air release" feature to let out excess pressure. The air gauge is a good quality. The pump is much quieter than I thought it would be. Comes with a very good carrying bag that has room to include any special fittings you may need. I did have my trailer plugged into electric power when using the inflator. The write up on it stated to have vehicle running while using. This is to give the 12V a little extra boost. This is understandable. The in-line electrical fuse would make it very easy to replace fuse if needed. I will be buying an extra fuse to carry just in case. ... show more
