An energy efficient electric control circuit for tankless automobile tire inflater machines wherein, in combination with an air pressure vent port, a current-draw tire inflation analog is created, said control circuit having current sensing means for tracking said inflation analog with such precision that virtually no extraneous compressor operation is experienced. The compressor operation is terminated promptly after tire inflation activity is completed rather than after a more prolonged fixed-time period.
