There is provided an electrically heated smoking system (101,201,301) comprising a secondary unit (105,205a,205b,305,407) capable of receiving a smoking article (107,207,307,411) having an aerosol-forming substrate. The secondary unit comprises at least one heating element (415) and an interface (109,209,309,409) for connection to a primary power supply (409) for supplying electrical power to the at least one heating element during a pre-heating mode, to increase the temperature of the aerosol-forming substrate to an operating temperature. The secondary unit further comprises a secondary power supply arranged to supply electrical power to the at least one heating element during a smoking mode, to maintain the temperature of the aerosol-forming substrate at substantially the operating temperature. The secondary unit further comprises secondary circuitry. The electrically heated smoking system may optionally include a primary unit (103,203,303,405) comprising the primary power supply and primary circuitry. By dividing the power supply between the primary unit and the secondary unit, the secondary unit can be made smaller and more convenient for the user. |
