RV air Compressor

This product was everything that I expected it to be. It makes tire pressure maintenance on my Diesel Pusher RV much less of a task. I got it for a good price. It has a nice carrying case to keep everything in place for the next use. Definitly a wise purchase.

I MADE A GOOD DECISION in buying this compressor
Great product to own for a variety of uses! Air Lifters on my truck need to be inflated, just bring out the Viair 400P. Cold weather means add more air to you car or truck tires, you're covered. It's hard to find air compressors at gas stations nowadays and if you do they're usually inoperative but if they are working I find they don't have the umph to handle my large truck tires. Owning this compressor has added so much convenience to my existence! I just it leave it in my truck. The product works great and the large dial air gauge is amazingly spot on.

If air pressure gauage is more precise, I will give it a five-star rating
Tire air pressure gauge is not precise. For instance, I need to inflate my tires to 61 psi, but I have no way to know if I actually reach this level. I had to use my another air pressure gauges to make sure I reach the exact level. Considering the price of this model, it is something the manufacturer should have considered improving.

Amazing Product

Many blogs on the internet stated how great this product performs, and the blogs are correct. Yes, it costs a lot, but for a portable unit or for someone that doesn't have a lot of storage space, it is an amazing product. The fact that it is made in China and still has a quality look, feel and performance, makes it even more surprizing. I may be a little skeptical of Chinese products, but then too, my wife is Chinese and as a rsult, I do have my bias.

Best pump

I am throwing away all former small pumps that never did the job that were loud, cheaply constructed and took forever to pump a tire.

This ViAir pump is unbeleivable.....really works ! cant say enough positives. The quality of this pump is immediately obvious.

Inflation can be a good thing in this case

Fortunately/Unfortunately I have not needed to use this yet so I really can't comment on it. I chose this item based on other reviews indicating that this is the best portable air compressor kit on the market for anyone with an RV or other road going vessel with tires which can deflate and go flat. This kit has all of the accesories and capacity you'll need for inflating whatever size RV tires you might have, especially those hard to reach inner tires with a very nice extended inflater along with more than enough length in the 2 airhoses supplied to reach this furthest tires you might have from the your 12V battery. Looks really well made. I hope not to have to use this for as long as possible. However, I'm sure that at least with my RV I will have a need unfortunately before too long as there always seems to be some form of tire trouble or air springs that need  re-inflating while on the road. A little pricey, but I also don't ever plan on buying another one at least not in this lifetime.

VIAIR 400P-RV
We haven't used it yet, but it is of excellent quality and everything is contained in the carry case. I am especially impressed with the construction of the coiled air lines. Thanks for the peace of mind.

Great product.
As a full-rver, the Viair 400P is portable enough to use on the road or in the campground. Had no trouble topping off our 5th wheel tires at 110psi.
