Tires are the foundation of your home while on the road. That’s why tire pressure maintenance is essential for all RVers.
The VIAIR 400P-RVS Automatic 12-volt portable tire inflator kit is specifically designed for Class C and larger towables. This 33% duty cycle compressor is the ONLY tire inflator on the market capable of airing up to 150 PSI.
The 400P-RVS has a newly integrated 40” 90-degree twist on chuck to make it easier for filling tires while standing. This compressor will inflate most Class C RV tires from 80 to 90 PSI in just 46 seconds. It can run continuously for approximately 20 minutes at 100 PSI before needing to rest. The “RVS” line is designated as “RV-Safe” because they are specifically designed and tested for the RV market. Prevent wasted time locating the nearest gas station (or avoid being stuck on the side of the road) by utilizing this fundamental tire inflator.
How to use: To use this compressor, simply attach the heavy-duty battery clamps to the RV’s battery and start the engine. Connect the tire chuck to a tire valve stem and turn the unit on. The 400P-RVS Automatic comes with a close-ended gas station-style air gun for added convenience and contains the automatic shut-off function of a larger powerful portable tire inflator. Each tire inflator comes equipped with hoses long enough to reach your RV tires, a convenient carry bag, and all necessary components.
Portable compressors with automatic shutoff provide an auto stop/start function similar to newer vehicles turn off when at a stop. This feature comes into play when moving from tire to tire, and when checking tire pressure in the middle of a tire fill. A typical portable compressor must be turned off between tire fills, and anytime you want to check tire pressure. If you aren’t near the compressor, this can turn into going back and forth from the tire to the portable compressor to turn the unit on and off. Automatic portables will save you time & effort to get tires inflated quickly. Comes with a 1 year warranty.

Hello, just made this purchase with the winterization kit. I have not used the compressor or kit yet but I have opened the package and I’m extremely happy with the quality of the products all the way from shipping, packaging, the build quality of the 400 and the carrying bag allows me to keep everything related to this product in one place. Way to go Techno Rv. I’ll update review after I prepare the rig for the winter off season.
The VIAIR works great, and you can really tell it is a quality unit!
This is a great little compressor, only took seconds to top off my truck tires. Love the automatic shut off when not filling the tires, prevents compressor over heating.
Outstanding pump. Very quiet in operation so you can fill your tires early without messing with your neighbors. Good volume and filled tires fast. Only negative is that you have to be careful as the pump gets hot. would recommend the auto operation as it cycles pump on an off
