Compressors with automatic shutoff come into play when moving from tire to tire and when checking tire pressure in the middle of a tire fill， h standard compressors must be turned off between tire fills and anytime you want to check tire pressure， if you aren't near the compressor， this can turn into running laps back and forth to the compressor to turn the unit on and off automatic compressors do not work in this fashion and will save you time and effort to get tires inflated quickly
