    The delivery to my address in Spain was super fast, just like the Viair compressor. Well done seller!
    The Viair compressor is very impressive. I’ve owned a twin head compressor and single head compressor (permanently mounted under bonnet) and in my opinion the Viair compressor performs better.
    The fact that the amp draw is a little less than its competitors is outstanding, no more struggling alternators, just fast inflation times, especially at night when all the spotlights are on and a 60 litre Engel fridge in the trunk. You don’t even have enough time for a beer, haha!
    The kit is complete and has a very useful carry bag that it comes with. It has enough space to carry other things, in my case, I carry a 12v battery jump pack which fits inside with ease.
    This compressor is the real deal without using a mains powered compressor

    The Viair 400P is a fabulous addition to my 2015 Jeep Wrangler Sahara. It make airing back up after a drive on the beach an absolute pleasure instead of a chore. The kit is complete, and makes the whole setup easy to transport and store. The compressor, and all of its accessories in the kit are complete and of the highest quality. The airing up process is quick, and problem free. With a bit of experience, the process for airing up four tires should take less than 15-20 minutes for all four tires ! Naturally, you must be careful as the compressor heats up during tire inflation, but with a little common sense, the entire operation is completely safe. If you enjoy driving off road or if you just need emergency air for tires, lifters or any number of inflatable toys or sports equipment, you need a Viair portable compressor. Yes, I would recommend this to a friend !

    4.0 out of 5 stars Overall satisfied
    Reviewed in the United States on January 15, 2024
    The pump itself is great and you can tell it s a quality product but the hose is really not useful.
    First the gauge is next to the tire you inflate so you need to go constantly between the pump and the tire if you want to adjust the pressure with the pump. The best is to inflate with a higher pressure and then deflate to get the desired pressure.
    Then the connector to the valve tire is with a 90 degree angle which makes it really hard to connect as it needs to be flush with the tire rim. I ended up making a new hose with a straight connector. It s more compact and a lot easier to connect.
    I also added quick disconnect at the pump with a digital gauge equipped with a deflation button so that I can adjust the tire pressure at the pump. I got everything from harbor freight for about $20 and it makes the system prefect. I don't know why they don't do something like this.
    Be also aware that this model doesn't automatically stop of you have an overpressure so make sure to only buy open flow fittings or valves. The 400 automatic has a pressure switch that stops the pump, so if you want to use an air pressure gun get the 400 automatic, not this one.

    5.0 out of 5 stars VIAIR 400P: Power and Convenience in One Package
    Reviewed in the United States on August 11, 2023
    The VIAIR 400P portable air compressor is a game-changer in the world of on-the-go inflation. With its impressive power and user-friendly design, it's become an essential tool in my automotive arsenal.

    The first thing that struck me was its sheer power. Capable of reaching a maximum pressure of 150 PSI, the 400P effortlessly handled my car tires, bike tires, and even inflatable water toys. Its fast inflation speed meant I spent less time waiting and more time enjoying my outdoor activities.

    Portability is a strong suit for the 400P. Its compact size and ergonomic handle made it a breeze to carry around, and the included carry bag added an extra layer of convenience. Whether I'm on a road trip or a weekend camping adventure, the 400P is always ready to assist.

    The built-in pressure gauge is a nifty feature, allowing me to monitor and adjust inflation with precision. The integrated LED work light proved to be incredibly handy during nighttime use, making the whole process smoother and more efficient.

    While not whisper-quiet, the 400P's noise level is manageable, making it suitable for various settings without causing a disturbance.

    In summary, the VIAIR 400P offers an unbeatable combination of power and convenience. It's a reliable and efficient companion for any outdoor enthusiast, providing peace of mind and timely inflation whenever and wherever you need it. If you're looking for a portable air compressor that delivers on its promises, the VIAIR 400P is the one to get.

    I own a junk removal company and the number of times we’ve blown or needed to patch a tire is astounding. I’d have you guess but you would guess low. So when I got this to keep in our truck I knew it would be put to good use! It inflates faster than any of the other ones I’ve tried, doesn’t over heart, was reliable and easy to store. Very happy with this purchase! It was also a great price!!!
