An article for use in a non-combustible aerosol provision system includes an aerosol-generating section with a plurality of strands and/or strips of aerosol-generating material. The aerosol-generating section is circumscribed by a moisture impermeable wrapper and a cooling section is provided directly adjacent to the aerosol-generating section. The cooling section can have at least one of a hollow channel having an internal diameter of between about 1 mm and about 4 mm or a maximum of 32% of the cross-sectional area of the cooling section being a hollow channel. A non-combustible aerosol provision system is also described.

An apparatus and a method for an aerosol generating device is described, the apparatus including a control module and a charging controller. The charging controller is configured to control charging of a battery at a first charging rate in a first charging mode and to control charging of the battery at a second charging rate, lower than the first charging rate, in a second charging mode. The control module is configured to determine whether the aerosol generating device is in use. The charging controller, when operating in the second charging mode, is configured to change the charging mode to the first charging mode in the event that the control module determines that the aerosol generating device is in use.
