5.0 out of 5 stars Solid performance
Reviewed in the United States on June 14, 2021
Aired down four tires for offroad (from 65 psi to 30psi). When it was time to air back up again to 65 psi all around, it took about 4 minutes per tire. This could be easily done without the unit needing to cool down. It has about a 20 minute run time per hour, which is enough to fully air up 4 tires. It is relatively quiet and has good reach for a 20 foot pickup. You don't need to move the unit to reach all four tires. The hose is long enough in addition to the long battery cables. Nice carry case too, that will fit a set of Coyote automatic deflators (which makes the air-down job incredibly easy and fast and accurate to whatever you choose for a preset deflation limit). Portable, small footprint, and very well built. Worth it. Don't go offroad without it.

5.0 out of 5 stars Moves a lot of air with ease
Reviewed in the United States on January 17, 2018
I first purchased a Viair 88P from amazon. When I received it the unit did not work properly out of the box. I immediately returned it to Amazon because of a factory defect and decided to order the 400P model because of its greater capacity to move air. I tested it on a SR225-75 large travel trailer tire as soon as I received the unit and was pleased with the results. It inflated the tire to 55psi in about 3 minutes. The cylinder was warm but not hot to the touch. The unit is larger and heavier than the 88P but was worth it because of its much greater capacity to get the job done. It comes with a cloth case that is adequate but not what you would consider heavy duty. It does keep all of the components in one place when needed. The size of the 400P in its case is to large to place under most passenger car seats but could be stored in the trunk or pickup truck tool box. If the components were separated without the case, they might fit under some passenger car seats. The removable air hose is coiled and compact and easily stretched out from the front of my 38' RV to the rear tires. Since it is equipped with an industrial type hose quick connector other hoses or extensions could be added but would probably not ever be needed. I would purchase this unit again and would highly recommend it to others along with a quick external tire puncture repair kit particularly if you drive long distances in rural areas.

5.0 out of 5 stars Actually able to achieve high tire pressure.
Reviewed in the United States on April 14, 2024
I've considered Viair for years but it wasn't until we had some RV tire problems last Summer and I had problems with the compressor I carried achieving the needed psi for my 5th wheel without multiple attempts. Upon it's arrival I parked my pickup beside the 5th wheel and tried this thing out as if we were on a trip. It may have performed better than my shop air hose. Very pleased.

5.0 out of 5 stars Very impressed with this.
Reviewed in the United States on November 25, 2024
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!!!

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.
