1. An aerosol-generating device comprising:
a housing of the aerosol-generating device, the housing defining an internal compartment adjacent a first end of the housing and a cavity adjacent a second end opposite the first end of the housing, the cavity configured to receive an aerosol-generating article, the aerosol-generating article including,
a first compartment including nicotine,
a second compartment including an acid source,
a susceptor configured to be positioned between the first compartment and the second compartment, and
a third compartment defining a space between outlets of first and second compartments and an outlet of the aerosol-generating device, wherein the third compartment configured to be fluidly coupled to the first compartment and the second compartment and the third compartment downstream of the first compartment and the second compartment;
at least one electric heater in the housing adjacent the cavity and configured to heat the susceptor of the aerosol-generating article to form nicotine and acid vapors at the outlets of the first and second compartments, respectively; wherein the nicotine and acid vapors mix within the third compartment and react to form an aerosol comprising nicotine salt particles for delivery to the outlet of the aerosol-generating device;
the at least one electric heater including an annular inductive heater extending about the first compartment, the second compartment, and the susceptor;
at least one airflow sensor in the internal compartment of the housing;
a first power supply in the internal compartment of the housing, the first power supply configured to supply electrical energy only to the at least one electric heater, the first power supply including a battery;
a second power supply in the internal compartment of the housing, the second power supply configured to supply electrical energy to the at least one airflow sensor, the second power supply including a battery;
a third power supply in the internal compartment of the housing, the third power supply being rechargeable, and the third power supply configured to supply electrical energy to the first power supply, the third power supply including a battery; a controller in the internal compartment of the housing, the controller configured to control a supply of electrical energy from the first power supply to the at least one electric heater during a heating cycle, and at an end of the heating cycle, supply power from the third power supply to the first power supply so as to recharge the first power supply, and the second power supply configured to supply electrical energy to the controller; and
at least one additional electrical component, the at least one additional electrical component including a feedback device, the second power supply configured to supply electrical energy to the feedback device such that the feedback device provides feedback indicating a start and the end of the heating cycle.
