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.

Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

I purchased this because my son has the 450P RV model. I went with the 400P Auto as I didn’t require the extra hose etc. Excellent product, definitely recommended.

I wish all compressor had auto on/off. To use it, simply turn it on. It will pressurize the hose and will then turn off. Then you can pump the tires. As you pump (press the lever on the air chuck) the compressor detects a pressure drop, and turns on. Very cool. So you just leave it on, and once you are done with all tires you then turn it off.The hose is nice quality. Light. The connectors on hose are brass.The air chuck and gauge are heavy duty. You can use a third party one if you like. Standard 1/4 NPT connectors are used throughout.The unit is very quiet when running, and does not vibrate like crazy. Comes with a nice rubber pad under the metal plate.Comes with a handy bag.Overall very happy. Wish it was made elsewhere though, I would be willing to pay extra for that.

Bought to air up 35 inch tires. Seems well constructed, fairly quiet and airs up the 35 inch tires quickly. Gets hot to the touch but they all do. The auto shutoff feature is well worth the extra cost. My only complaint is that the included airline has female couplers on both ends, and the compressor is male. If you buy an aftermarket airline with couplers installed they come in a male/female setup which is correct. The compressor should have a female coupler. Just something to keep in mind as you will have to swap out the coupler. Other than that it's a really good compressor, recommended 👌

I had the 90P which being lighter was certainly more convenient to use.The 400P is bulkier but still quite okay. The high quality pump is definitely impressive. Very well built. The gauge is also quite bit better than the one with 90P.The coiled 1/4" air hose could be improved. I'm going to find a shorter, flexible, straight, standard hose so I don't have to use it.The valve clasp is very stiff making it hard to put on and difficult to remove. Don't see a fix for this.The carrying bag is really a nuisance. Looks fine but gets in way. Hard to believe a company as good as Viair would tolerate it.The automatic feature is nice and almost forgives all less desirable features.

It is a great compressor. Reliable and fast. I use it when I go off roading to the desert (once every two weeks) and need to air down my stock tires (about 31 inch tires) on my 2019 TRD OR Tacoma. It takes me about 10-15 minutes to air up from 18 PSI to 40 PSI. The nice thing about the pistol you use to air up is that you can also use to air down!! Just connect it to the tire and press the trigger and it begins to release air while checking the tire pressure every few seconds with the gauge on the pistol. I absolutely love this thing. Oh and I also use it to help my friend air up his 33 inch tires after I have aired up mine, without having to wait for the compressor to cool down. The auto shut off mechanism is very nice to have because it automatically turns off when you're not airing up. This helps the compressor cool down and prevents over pressure from damaging the it. Well worth the money.

If you have 35 inch tires, you need this. The Viair 400P is the nicest personal tire pump I’ve ever owned. If you have a Smart car, or a Prius, stop reading. This is not the pump for you. As a former owner of both of those cars, I can attest to the fact that this pump is nearly as big as they are. However, if you have a large truck or other vehicle with big tires, buy it now. As the proud mama of a 2018 Ford Raptor, I can’t imagine trying to fill my tires with a little air pump that plugs into the cigarette lighter. Yes, this pump is heavy. Yes, you have to put it together and take it apart to get it in and out of the bag, but it is easy and it operates smoothly and quickly. It has a lever to secure it to the tire stem, a nice big gauge, and it operates on demand - so when you press the lever, it delivers air. 10/10 Will bore my friends with tales of the air compressor.

Unpacked the unit, read the paper work and assembled the intake filter and connected hoses. All went together well, but threads on air filter were kinda rough, added a VERY thin coat of light Yamaha lube and it smoothed out and all tightened down nice.Tested it out on two of my F150 20" tires aired down below 20#, the unit was able to air them up to over 40# both in less than 2.5 minutes. The automatic feature is great as even though the unit is only 33% duty cycle, it shuts down automatically unless its coming up to pressure, or actually pumping air in to a tire. I can't see the duty cycle being an issue with this nice feature and given how I will primarily use it. I should be able to top up all 4 20" tires coming off the beach in about 20 - 25 minutes including setup and pack up and with only about 15 minutes run time on the motor.Unit is quiet and seem very well built, time will tell how it holds up. The chuck assemble clamp locks down on the valve stem nice and with the handle having an air down / release button its quick to use to air the tires down too.Unit was only warm to touch after the first 2.5 minutes for the first tire. But even after the cool down moving to the second tire which included time for the air down of that tire, after the next 2.5 minute on cycle the head was too hot to touch. So I full expect it to be very hot after all 4 tires. But with the auto shut off, the overheat and over pressure safety shut-offs I cant see the heat being an issue, but again time will tell how the unit handles that heat.The case and accessories seem good, looking forward to making use of it coming off the beach. Only concern after using it would be the durability of the chuck assembly, seems like its maybe a step down lighter in duty than the actual pump assembly itself. Will see how it holds up after practical use and a couple of drops (accidental) to the pavement.Even though the $180 I paid for it is more than I wanted to invest, this unit seems like the best option for quick air up and compact size / low weight. If I had to complain about anything, I'd say it would be more convenient to not have to pop the hood and connect to battery, I can see this being a PIA in bad weather. A nice option would be to hard wire some connections to battery that had exterior accessible jacks on the vehicle; then be able to replace the battery clamps with mathings plugs to mate to jacks. If I was younger I'd consider doing a custom wiring job myself.Overall seems like a great job anyway ViAIR !!!

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.
