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.

I love this air compressor.The product I received is not exactly what was described. I contacted Viair, and found that I had received a newer model than described with the following differences:1. The air hose is black, and an updated version. Very happy with this.2. The gun is a 160psi gun, NOT 200psi. This change was made because 200psi is overkill for most people. I prefer the 160psi for my use, the dial is easier to read. I love it.I have a 2015 Jeep Wrangler Unlimited. This is a perfect compressor for my needs. It is extremely easy to set up and light to carry. The air hose has more than enough length, I can get to my spare without any pulling or stretching.The compressor is quiet and quick. Using the release valve in the gun, I deflated a tire to 20psi (very quickly, great valve). I then inflated it to 36psi in less than a minute. The compressor worked beautifully. It will automatically shut off if the trigger on the gun is not depressed for a few seconds, and start again when the trigger is depressed.This compressor comes with the filter assembly ready to attach. It is easy to put on, contains a 2 part filter already, and has two spare filter sets in a separate bag.The bag is extremely nice! Very rugged, and well balanced. The compressor seems very secure in the bag, and the hose fits perfectly up front. There are two small side pockets, one with a flap and one with velcro. There is no separate pocket for the gun, though. I wish they had included this. I will find a pouch to protect the dial.As important as all of the above: Viair customer service is amazing! The rep I spoke with was very friendly and knew absolutely everything about the product. She answered all my questions quickly and was a joy to speak with.I definitely recommend this compressor.

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.
