摘要： A power supply unit for an aerosol generation device includes: a power supply; a first connector connectable to an atomizer for atomizing an aerosol source; a second connector connectable to a heater for heating a flavor source; and a processing device configured to acquire a temperature of the flavor source or the heater. The processing device is configured to start second discharge from the power supply to the heater to make the temperature of the flavor source or the heater converge to a target temperature, before starting first discharge from the power supply to the atomizer, acquire an elapsed time between a start time point of current second discharge and an end time point of a later one of previous first discharge and previous second discharge, and increase power in the first discharge more and/or decrease the target temperature more as the elapsed time becomes longer.
