From the brand

-
Does the engine need to be running to operate the compressor?
The compressor needs a constant 13.8 Volts for optimal performance, and that is only possible with the engine running.
What is duty-cycle?
It’s the maximum continuous run time of the compressor, expressed in % of 1 hour.
Is a direct-drive motor better than a gear-drive motor?
Direct-drive motors deliver power straight to the piston rod, it is quiet and reliable. Gear-driven motors have an extra layer of friction, creating a louder system that’s prone to rapid performance decline due to deteriorating gear teeth.

Compressor duty cycle refers to amount of time a compressor can be operated in a given time period, at 100 PSI and at a standard ambient temperature of 72°F. Duty Cycle is commonly expressed in percentile as: compressor on time (compressor on time + off time) %. As an example, a compressor that is rated for 25% duty cycle means that compressor can be operated at: 100 PSI @ 72°F for 10 minutes on and 30 minutes off. 10 min. on / (10 min. on + 30 Min. off) = 10 min. / 40 Min = 25% duty cycle.

-----------------------------
Desert season hasn't started yet, so I'll have to come back and amend this review when I use it to air my actual truck tires back up from a target 20psi, but have had the opportunity to use it in a few cases.
1. Bicycle tires air up great.
2. Aired up my friend's truck tires as they were a little low.
3. Have used it to air up a vessel I made for pressurized camp water.
All three situations, this compressor rocked. As is, I mounted this into a front plate bumper on my Tacoma where a winch is supposed to go. I used 5 feet of 8 gauge AWG for my lead wire to a 20/40 amp relay connected to a 25 amp fuse and just grounded it to where my light bar mounts without having to extend the factory negative wire. Got an OEM style switch for the center console to run the relay and connected that to a 3 amp fuse. Yes, you're going to need to buy all this stuff separately. VIAIR can't predict how you're going to mount it, so don't accuse them of being cheap.
Long story short, I'm more than happy with this compressor so far. It gets hot, but not too hot, and it handles load well. We'll see how it does out in the desert where I really need it to work and if it can tolerate the dirt and water I'm going to be throwing at it come fall/winter.
Update: it's been 4 weeks, since install ive had zero issues. Testing shows it fills roughly 3 times faster than vixen and only runs around 2 minutes to regulate 115psi to 140psi on my 7 gallon tank. Very impressed and will recommend.
2023 update. Been using on and off since purchase and no issues filling up my 5 gallon air tank and filling tires or using any random air accessories. Using remote mount for the air filter to keep out potential water ingestion. It's been through water, mud, dirt, and sand all these years and still works fine.
