Abstract: An aerosol provision system includes a consumable with an aerosol generator and aerosol-generating material, and an aerosol provision device to control power provided to the aerosol generator to energize the aerosol-generating material to generate aerosol. The consumable is one of a plurality of types of consumable having target values of an electrical characteristic that are associated with respective power modes of different levels of power for different amounts of aerosol generated from the aerosol-generating material. The aerosol provision device measures the electrical characteristic of the consumable to obtain a value, and identifies one of the target values that most closely matches the value. The one of the target values is associated with one of the power modes of a respective one of the different levels of power. And the aerosol provision device controls the power provided to the aerosol generator to the respective one of the different levels of power.
