What a relief it is to not have to find a gas station that has air that I can get my 40 ft toy hauler into position without blocking all the lanes. I think it was important to get the unit that shuts off so you can read the PSI. Love it.

Very expensive but works quite well and constructed of top-notch materials.

I purchased this VIAIR 400PA-40045 compressor kit Jan 2021, to use when I go beach driving in my Ford Raptor. It looks to be well made. I have only tested the unit to see it operates and pumped up my tires a few psig. The pressure gauge seems to be accurate when I compare it to my portable pressure gauge. I like that it has its own bag to store the unit. I read many reviews on different battery operated compressors and settled on this unit due to the positive reviews and its capability to pump up my 33 tires. So far I am happy with the unit.

Works great. I had a Superflow MV50 not as nice.
It works as it should. To soon to evaluate further.Note" I already have the Constant Duty ADA,Base Model Kit,110/145 in my truck hard mounted and give it a 5 out of 5 stars. "Sweepstakes"
Small but powerful - exactly what one needs for RV tires!!
Product is as advertised
Good quality and quite operation. Inflated tire surprisingly fast.
A very nice air compressor! Like it alot!
love that it shuts off when not being used for less wear on unit .
