Abstract
A vapor provision system comprising a heating element for generating vapor from a liquid vapor precursor material and a wick for transporting liquid vapor precursor material from a reservoir to the heating element. The vapor provision system further comprises a user activation mechanism for signaling the user's intent to start vapor generation and configured to be actuated by a user and control circuitry configured to supply a constant average voltage power to the heating element in response to a signal output from the user activation mechanism. The control circuitry is configured to supply the constant average voltage power to the heating element regardless of the temperature of the heating element.
