Compatible with All Vehicles From trucks and SUVs, to motorcycles and side-by-sides, this small air compressor is portable and powerful. Filling a 35-inch tire from 15 to 30 PSI in less than 2 min 45 sec or less, the 400P gets you back on the road in minutes, no matter what rig you drive. Fast & Easy to Use – No Programming Required Attach the alligator clips to your vehicle's battery terminals, start your engine, turn the compressor on and it will pressurize the hose to 150 PSI and turn off.

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: Thank you Viair - Viair is top of the line as far as I’m concerned. It is well built and constructed with quality components. This is my second unit. I also have one for my RV. I tried this unit out today and I am dutifully impressed. The gauge is spot on accurate so no need to double check the pressure with a small handheld gauge. It seems to be quieter than my older unit and it is also smaller and lighter. This 400P Automatic is the way to go because it has a built-in PSI regulator that turns the unit off when it is not being used. Meaning it doesn’t run continuously when turned on. Big big upgrade from the regular 400P and I highly recommend this version. I think it is definitely worth the extra cost. This compressor is going to be kept in my Jeep for off-road adventures. Super happy with this upgrade.
Review: Super Off-Roading Compressor - Fast Air Up Large Tires - Good Purchase ! ! Tremendous heavy duty compressor for off-roading. Fast air up 37" tires. Super reliable and 10 lbs not too heavy. Tough compact nylon carry bag holds everything - compressor, 30 ft coil air hose, air-gun, and so forth - all in one tough nylon case. Built-in SAE 12v connector makes easy connection w 12 AWG battery cable installed separately. The air-gun needs some work -- -- First, remove short floppy hose w lousy right-angle clamp. Port thread is 1/8 NPT. Use adapter to 1/4 NPT. Add brass twist-on chuck to Schrader - see photos. Now can use Schrader hose any length desired. And for easy connect to valve stem use JACO Lightning S2X extension w Self-Locking Nozzle -- -- Second, remove large 150 psi gauge. Again port thread is 1/8 NPT. Replace w MEANLIN gauge 100 psi (or 60 psi) w 1/8 NPT Lower Mount. Now have more compact air gun w custom length hose and better gauge for standard tire pressures

## Questions & Answers

**Q: Can this unit be used with a normal electric outlet or do I need to buy an ac/dc convertor when I want to use it in the garage without a battery?**
A: This unit is strictly a 12 volt DC powered compressor. If you wish to use this on house current, you will need to use a 12 volt DC power supply which could handle the required amperage. I would suggest a small car or lawn mower battery of at least 100 ampere capacity. Put a trickle charger on it and you would good to go. Most of these battery powered compressors will draw considerable current during operation and they will get hot so be sure to take care when operating and keep the compressor clear of any combustible items.

**Q: What does the “automatic” refer to?**
A: According to a customer Service rep at Viair, the 440P-auto does NOT let the user set a desired pressure and then automatically shut off when the tire reaches that pressure. All it does is shut off when it meets the compressors max rated pressure. Perhaps the service rep did not know what he was talking about, but if that's all it does, the feature is just about useless: If you pump a typical tire up to 150 PSI, you most likely have already damaged the tire.

**Q: What is automatic about it? does it shut off a a set psi?  i want all my tires at 32**
A: Hello,
The automatic feature is not a "set it and forget it" type. You will still have to manually control the pressure for each tire. Our portable compressors with the automatic feature really helps when moving from tire to tire, and when checking tire pressure in the middle of a tire fill. Non automatic compressors must be turned off between tire fills, and anytime you want to check tire pressure. That means you'll be running back and forth to the compressor turning the unit on and off. The automatic feature will save you time & effort to get tires inflated quickly.

Thanks,
VIAIR Corp

**Q: Must you continuously hold the lever on the inflation gun to inflate a tire? Seems like that would be very tiresome to do anything but add a few lbs.**
A: It doesn’t take that long to fill em. I’d rather hold the chuck in one hand and and a beer in the other than get distracted and forget it. The original filler clip fell off the stem a lot and made it a 2 hand job so I got another one at Home Depot for 20 bucks. I carry regular chucks and lots of other spare parts like valve stems and covers. When I air down I pull the stems right out. When I’m filling  I have a small fold up stool to sit on (or my cooler)and a digital gauge. I always have extra valve covers too. Most of the stuff Fits in a pill bottle. I carry an extra 25’ hose in case. Happy trails.

### ⭐⭐⭐⭐⭐ Great inflator—nice automatic inflation feature
*by C***R on December 6, 2025*

Works as advertised. Fast inflation, not too loud, decent cables and alligator clips. Must be hooked directly to your car/truck battery terminals. Stays self-contained in the case (included). It does get warm after long run times and needs to cool off. The automatic inflation feature is convenient and is a must (it turns off compressor when it reaches pressure, and only activates upon demand).
