Abstract: Described herein is an aerosol-generating device for generating aerosol from an aerosol-generating material. The aerosol-generating device comprises a heating assembly having a mouth end and a distal end. The heating assembly comprises: a first induction heating unit arranged to heat, but not burn, the aerosol-generating material in use; a second induction heating unit arranged to heat, but not burn, the aerosol-generating material in use, the first induction heating unit being disposed closer to the mouth end of the heating assembly than the second induction heating unit; and a controller for controlling the first and second induction heating units. The heating assembly is configured such that at least one induction heating unit reaches a maximum operating temperature within 20 seconds of supplying power to the at least one induction heating unit.
