How long should it take to inflate a tire?

For a passenger-car tire going from roughly 25 to 35 PSI, reviewers in the threads we read typically report 1-3 minutes on decent cordless and 12V units. Full 0-to-pressure fills on truck tires can take 4-7 minutes on heavy-duty compressors and significantly longer on small cordless units, several reviewers note small batteries dying before all four tires are done.
