400P Exceeds Expectations
After paying $2 to inflate 4 tires at a gas station decided to buy my own inflator. After weighing cost/benefit options chose the Viair 400P. Initially balked at the price but I hate crappy products. Any worry about my choice disappeared with a thorough inspection. Buying online can be a crapshoot but this unit is quality built. Bag is medium grade and could use a third small compartment for filters and extras but a minor issue, also the instructions are in tiny print and hard to read for us old geezers. Showed the 400P to my mechanic and he was very impressed. His first comment was wow even the hose is high quality! Never thought I'd be excited to inflate tires but using a quality tool like this is a pleasure. This pump is fast, easy to use and has a nice sound to it. The pressure gauge as others have noted did not seem accurate. An issue for cars with short valve stems is the horizontal inflator chuck won't fit unless you have enough clearance above wheel cover surface. I bought a 6" flexible valve extension which solves the problem. Read some reviews complain of the 8' power cord as too short. Easy hack is use your jumper cables as extensions. A decent 16' 4 gauge cable will triple your power reach. Saves moving back and forth to turn pump on/off when filling. Also, buy a spare 40 amp fuse JIC.

Compressor with some good power.
The compressor works well, I have used it to fill the RV tires to 80 PSI with no issues. It is quick and having the case to store it is nice, I do wish the battery connections were a bit longer. I had a hard time reaching my rear tire on the 32’ RV. It was pretty quiet for the most part. Had plenty of power to pump up the tires and the tire gauge works well.
