Review on VIAIR 400H Hardmount Compressor: Ultimate Power for Heavy-duty Applications by Andre Bennett

Used a few times on a 5000 mile ride in Baja. You flip the switch, it lights up, pump up the tires. Not as much. So far I haven't worked hard enough to turn off the thermal switch, although it does get hot enough to send you for a pair of gloves. For inflating 35" tires from 18 to 35psi. I didn't know how long it took, but it was good. Looks well built so I installed it under the hood on the fender. end of the lead hose. Went to a hardware store and grabbed some stainless steel fasteners because I didn't like the look of the materials that came with it. Reinforced wiring with heat shrink tubing and correct ends. So far no problems.
