## Description

Product Description The VIAIR 400P AUTOMATIC 12 Volt Portable Air Compressor for Truck Tires The 400P tire pump for trucks, SUVs, RVs and more is portable, lightweight, and has an automatic shut-off setting. With a maximum dimension of 10.87 inches and weight of 10.7 pounds, it's easy to store in your trunk or top box for easy access and never be without air. Electric Truck Tire Pump with Carrying Case Conveniently stored in a durable canvas carrying case with top handle, the 400P tire inflator air compressor is ready to use at any moment, whether you're at home, stopped on a busy roadway or out in the middle of nowhere. 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. Connect the air hose to your vehicle's tire, and start filling with air by pulling the trigger on the inflation gun. 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: Solid product - Yes, this thing was made in China but what are we going to do, they all are. I have used this unit several times since I got it and it rides in my SUV everywhere. You can fill up truck tires and smaller items like bicycle tubes just fine. This model has auto shut off so you can use it by only squeezing the triggle, you don't have to keep turning the unit on and off. I like this because I can have the trigger part far away from the pump where the on off swicth is. The unit must be connect to a car battery to work. FYI> I contacted the company here in the USA and they said you "can't" make it run from a transformer if you want to rig it to work from a home recepticle. They also answered a number of other questions, were quick to reply to my email and seemed customer service oriented. I would recommend buying from this manufacturer. The unit seems of very good and solid quality. The hose disconnects from the trigger and from the pump so if you want to change the components out, you could. The triggle with the guage on it is quite nice and heavy and better than I thought it would be. The only complaints I have with it is, I wish I didn't have to have it attached to the car for operation. It would be great if I could plug it in to a wall receptical because it is so handy, quick and easy to use. I also have never been a fan of the type of valve that is used in this unit to attach it to a valve stem. There are only so many ways to do it but trying to hold the valve tightly enough on a stem while using a great deal of strength to flip the switch closed is something that has left me wanting since I was a kid trying to pump up my BMX tire. It works great, I just like the service station type valve better. Maybe it could be changed out later I guess. Overall good product, highly recommended.

## 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.

### ⭐⭐⭐⭐⭐ Quality and convenience - Love it
*by D***N on January 7, 2021*

I've already used this a few times and I love this thing. I have a full size compressor that I hated dragging out to put air in tires ( I bought the full size air compressor for nail guns and blowing out the pool lines). In the past few years I have bought less expensive mini air compressors for my tires and they have always been horrible, but they were also in the 50 dollar price range. Tires, especially in the winter need to be topped off and unfortunately my luck with nails in my tires has been horrible, ( I also travel with my own plug kit because of this) in the past year I've had to put a plug in both my wife and one of my tires. I keep it in my truck at all times and the piece of mind alone is worth it. Anyway to get to the point, I bought this one because of the quality, the standard quick connect fittings and most importantly, the trigger to start and stop the air on the fill side, meaning the air gun & gauge. This feature should be on all models if you ask me, yes it is worth it but missing from most travel compressors. So the quick rundown: it works really fast, it's not crazy loud, and the air hose reaches all the tires on my truck, so absolutely no complaints. The bag is sturdy and I see it lasting a long time, very easy to use and I hope it lasts forever. I love it. For anyone who cares, I also travel with a Noco boost, in case the battery should ever die on me, and I keep a quick connect attached to by battery at all times, so I don't have to use the alligator clips for the boost. (NOCO GBC009 Boost 18.5-Inch SAE Adapter Extension Cable For GB20/GB40/GB50 NOCO Boost UltraSafe Lithium Jump Starters) And then I bought an SAE cord, cut it , then I cut the cord to the alligator clip on the compressor and spliced in the SAE cord, also switched out the fuse to match the one on the compressor. So now when I need the compressor I just plug it into the quick connect instead of the alligator clips. I highly recommend this, especially if your battery, like mine ,is buried and you can't easily get to the terminals. - I am all about making life easier, especially if you are broken down on the side of the road.
