A battery unit for a favor inhaler includes a chargeable and dischargeable power supply, a connection part capable of electrically connecting to an external charger, and a controller configured to perform control regarding at least the power supply, wherein when an accumulated value of a connection time period to the charger exceeds a first predetermined time period, the controller determines that the power supply has been degraded.

A device for an electronic aerosol provision system that includes an indicator for showing power level. The device comprises: a battery for providing electrical power to an aerosol generating component in the system; an indicator light configured to emit a light signal for a signal period that indicates a level of electrical power available from the battery; and a controller configured to activate the indicator light to emit the light signal after detecting that a puff period on the system has been completed.

An aerosol generating device is disclosed comprising a heater for generating an aerosol and a vapour flow passage configured to transport the generated aerosol from the heater to a mouth end of the vapour flow passage. The vapour flow passage is extendable such that a length between the heater and the mouth end is adjustable.

A vaporiser for an aerosol generating device comprises: a heating element including a sheet of heating material; a tubular heater housing arranged to hold the heating element within the heater housing; and a liquid store . The heater housing comprises a longitudinal gap running along the length of the tubular heater housing, and the heating element is arranged such that a peripheral edge of the heating element is supported within the gap. The gap is arranged to allow a liquid to pass from the liquid store into the heater housing to be vaporised by the heating element during use. The size of the gap is variable to change the rate of liquid flow through the gap , and, in particular, to maintain an optimum liquid flow rate despite a varying viscosity of the vaporisable liquid due to temperature or to differing types of vaporisable liquid being used.
