What CFM do I need for a truck air compressor?

For tire inflation, 1-2 CFM is sufficient. For air tools, you need 3-5 CFM. Portable compressors for trucks typically provide 1-3 CFM at 90 PSI, adequate for most on-the-road needs.

What's the best power source for a truck compressor?

12V DC compressors plug into your truck's cigarette lighter or battery — most convenient for on-road use. Dual-power (12V/120V) models offer flexibility for shop and road use.

How long does it take to inflate a truck tire?

A quality portable compressor inflates a standard truck tire from flat to 35 PSI in 3-5 minutes. Larger tires (35"+) may take 5-8 minutes. Duty cycle matters — avoid cheap units that overheat.

Should I get a portable or mounted compressor?

Portable units are versatile and affordable ($50-$200). Mounted/ onboard systems provide higher capacity and convenience but cost more ($300-$800+) and require professional installation.

What features should I look for?

Key features: auto-shutoff at target PSI, digital gauge accuracy, thermal overload protection, adequate cord/hose length, and duty cycle rating. Stainless steel components last longer.

Can I use a truck compressor for other tasks?

Yes, most truck compressors handle tire inflation, sports balls, air mattresses, and light dusting. For air tools (impact wrenches, spray guns), you need a higher-CFM stationary compressor.
