From Road to Trail VIAIR's battery powered air compressor pumps are loved by daily commuters, families, and extreme off-road enthusiasts alike for their powerful, reliable performance in a small package. 12V Battery Clamps for Higher Performance Offroading applications have higher performance demands that cigarette lighter plugs are unable to meet. Enthusiasts prefer direct battery connections for their trucks, Jeeps and 4x4s because it accommodates the increased current draw of larger, more powerful compressors. While VIAIR does offer cigarette lighter models, we recommend compressors with battery clamps for serious for offroad use.

Review: A must for off-roading. High quality and reliability for the road rarely travelled. - As someone getting into off-roading, having a air pump is a must after airing down and hitting the trails. After extensive research and reading desertcart reviews, we chose this one. It has worked flawlessly so far and I feel great about the build quality, especially since there is a warranty. When using, it does get a bit hot so don't touch the hose to the body while in use. Otherwise I expect this pump to bring us happiness after off-roading for years to come.
Review: Moves a lot of air with ease - I first purchased a Viair 88P from desertcart. When I received it the unit did not work properly out of the box. I immediately returned it to desertcart 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.

## Questions & Answers

**Q: how long will it take to pump 4 off  265/75/16 from 15psi to 60psi**
A: My tires are 285/75R16 and it takes about 4 minutes to air up from 30 psi to 65 psi (each tire). So, about 16 minutes for all four. The run time is 20 minutes per hour, so no cool down is necessary with the 400P model.

**Q: Can it fill 5th wheel tires to 110 PSI  ST235/85R16  (G)**
A: The specifications on the manufactures website says the max working pressure of the 400P is 150 psi. Please note the 400P has an 8ft power cord and 25ft air hose. Depending were you will receive power from, you might want to consider also purchasing the 30ft extension hose. Viair part number 00030.

**Q: I have 33x12.5.15 inch General Grabber offroad tires, will this compressor work well?**
A: I also have 33x12.5 off road tires that I air down on the trail and use this compressor to air them back up. It works well and it is quick.

**Q: The 400p says both 2.3cfm and 2.54cfm while the 300p says both 2.3cfm and 2.4cfm. what is the advantage of the 400p over the 300p, if any?**
A: 400P Specifications - 12-Volt / 24-Volt- Permanent Magnetic Motor- Duty Cycle: 33% @ 100 PSI- Max. Working Pressure: 150 PSI- Max. 12V Amp Draw: 30 Amps300 P Specifications 12-Volt- Permanent Magnetic Motor- Duty Cycle: 33% @ 100 PSI- Max. Working Pressure: 150 PSI- Max.

### ⭐⭐⭐⭐⭐ A pump that works!
*by L***L on July 21, 2025*

I’ve been trying to find a portable tire pump that works on truck tires for along time. I finally found one! My rear truck tires need to be pumped up to 80 lbs when towing my travel trailer. My travel trailer tires need 75 lbs. The cheap little air compressors you can get at Walmart or here on Amazon we’re not up to the task. Several of them boasted 150 psi capable, but wouldn’t go past 73 psi. Took a chance on this one and what do you, it fricking works great. It’s fast, quiet, and doesn’t heat up to ridiculous temperatures. The pressure gauge is accurate (I checked using my other tire gauge). The size of the pump is small enough to fit in my kit and the included carrying bag keeps everything organized. So far, I couldn’t be happier.
