1. A power supply unit for an aerosol inhaler, the power supply unit comprising:
a power supply able to discharge power to a load for generating an aerosol from an aerosol generation source;
a temperature sensor that detects temperature of the power supply; and
a charger configured to convert power, which is supplied from an external power supply, into charging power for the power supply,
wherein the charger includes an information input part, and is configured to be able to supply one of a first charging voltage and a second charging voltage lower than the first charging voltage to the power supply, based on an input value which is input from the information input part,
a fixed value which is predetermined as one input value can be input to the information input part,
the fixed value is a value for supplying the second charging voltage to the power supply, and
the fixed value is constantly input to the information input part regardless of the temperature of the power supply from a beginning to an end of charging when the power supply is being charged.
