Used it to inflate my 265/65/r17 tires after driving through the desert. Was able to get up from 15psi to 35psi in under 10mins for all 4 tires. Connecting the air hoses and even to the battery was quite simple with no sparks or any shenanigans. Straight forward usage, not as loud as I thought it'd be, on the far end of the vehicle, it was barely audible. I'd recommend it. Easy to store in the bag too. Very convenient

I have a triple axle 5th wheel that calls for high tire inflation rates. I had bought a cheaper inflator from one of the big box stores but it self destructed after the third use. The Viair line comes highly recommended and I can attest that it's a great unit. While it is admittedly rather expensive, it does it's job beautifully and is quieter than I expected. I am extremely pleased with my purchase.

This is a great compressor! It is compact and has a durable carrying case to keep all components organized. The compressor works great on my Class C motorhome wheels. Comes with lots two hoses that reach from the front of the right all the way to the back. Abd the battery cables are of nice length too. Easy to use, low noise level, and love the auto shut off feature. I do recommend this to any RV owner.

I recently purchased the VIAIR 400P-RV/40047 Automatic Portable Compressor, and it has been an outstanding addition to my toolkit. From the first use, the quality of this product stood out. It's well-built, robust, and feels like it's made to last, which is exactly what I was looking for. One of the most impressive aspects of this compressor is its noise level.

This is a significant advantage, especially when inflating tires in quieter campgrounds or residential areas, where minimizing noise is essential. The performance of the VIAIR 400P-RV is top-notch. It's efficient in inflating tires for my RV, truck, and Jeep, making it a versatile tool. The 150 PSI/2.30 CFM specification means it works quickly and effectively, saving me time and effort. Additionally, its portability is a huge plus. It's easy to store and carry around, making it an ideal tool for road trips and outdoor adventures. Another aspect worth mentioning is the simplicity of use. The kit comes with everything needed to get started, and the instructions are straightforward, making it accessible even for those who are not air compressor savvy. In conclusion, the VIAIR 400P-RV Automatic Portable Compressor is a fantastic investment. Its combination of quiet operation, robust quality, and excellent performance makes it a top choice for anyone in need of a reliable air compressor for RV, truck, or SUV tires.
