    Something you need to know.
    Overall I like the product very well. Easy to use and inflates in good time. I have used it several times on our car, truck and travel trailer. The issue I have found is it does not work well when trying to fill dulies. Trying to fit the valve and lock it in, is next to impossible. There needs to be an adapter you can attach a duck foot so you can fill the tire eaiser. I'm going to adapt it myself so I may use it eaiser. Good product overall but that part doesn't work well in my situation.

    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.

    I love this pump. I air up 33" tires from 12 to 30lbs in about 2 minutes. Very easy to set up and use, and the included storage bag is nice to keep it all together. I would definitely recommend this to anyone looking to air up anywhere, anytime.

    I'm very frugal so it was difficult for me to spent this much $ for a tire inflator, but I'm glad that I did. I have a motorhome and I've had issues with other, cheaper, tire inflators being able to inflate my big, high pressure tires. The build quality of this inflator is excellent and it certainly gets the job done. I highly recommend it. You get what you pay for.

Whether tackling rocky trails or cruising through sandy dunes, this compressor ensures that my tire pressure is always at the right level for peak performance.

    One of the standout features of the Viair 300P is its compact design. This compressor is incredibly easy to pack, making it a space-saving solution for my overland journeys. Its portability is a game-changer, fitting seamlessly into my gear setup without taking up valuable space. The included carry bag adds an extra layer of convenience, keeping everything organized for quick access when needed.

    A minor downside to the Viair 300P, it's the noise level during operation. The compressor emits a noticeable drone that, while not a deal-breaker, might be a consideration for those who prefer quieter tools. While the noise doesn't compromise performance, it's worth noting for those who prioritize a quieter environment.

    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.

    Took a trip this weekend to big bear off-road on the trails of the north and south side of the lake and got to use the compressor for the first time. After getting on the trail I aired down to 20 lbs with my ARB tool. When I went to air up the pump was extremely easy to connect to my battery and reached all 4 ties with n o issues. The coil hose was long enough and did not put any tension or pull the pump over. When I hooked up the valve it read 20 lbs just as I had left it. I filled each one to 45 lbs and the gauge was perfectly accurate after double checking with a separate gauge. The pump was EXTREMELY quite which was nice not having a tiny pump screaming in your ear.

    I couldn't be happier with it and would 100% recommend. 5 STARS!!

    I ordered this because my previous plastic, cigarette lighter connected air compressor would take forever to air up a tire and sound horribly loud. This VIAIR compressor is soo much faster and quieter. Also it appears to be solidly built with mostly metal parts. The air hose attaches to a standard pneumatic fitting which means if the air hose gets damaged or leaks overtime, it will be easy to replace it with any off the shelf pneumatic air hose.
    It will fit behind the rear seat storage area of a Tacoma Double Cab (2010) if you rearrange the accessory bag and place the air hose on top of the compressor in the main compartment of the bag.
    The only problem I found with this unit is that the air hose took a lot of force to get it to connect to the compressor fitting. Hopefully it will get easier with time.

    I purchased this mainly to air up after off-roading. Now, I make sure it is with me everywhere I go. I’ve used it several times a year since I bought it and it is still in great shape and works like new. I suggest buying a tire plug kit and tossing that in the bag with this compressor.

    Very nice little unit. Well constructed. Inflates my 32" tires at a good rate. On a recent trip, I took 4 tires from about 18 to 35psi in around 10 minutes. Much faster than department store junk. It runs quite quiet as well. The cables are not very long, so you really have to stretch out the coil hose to inflate the rear tires. The carrying case seems to be a little oversized for this small unit. Additional intake filters are provided, which is a nice touch. Overall, I am very satisfied.

    Very good quality compressor, builds up pressure very quickly... I was able to fill a customers 16'' tire from 11psi all the way to 32psi in under 40 seconds. The leads are very good quality and they are also fused for protection. I didn't however use the supplied air hose and air chuck as I found it too short to make it all the way around the vehicle so I use my 50' foot air hose and my snap on air chuck to fill them up. Just remember that it is a compressor and it is air cooled and it will get HOT! so let it cool before handling again. Highly recommend
