1. An electronic vapor provision system including:

  • a vaporizer for vaporizing liquid for inhalation by a user of the electronic vapor provision system;

    a power supply comprising a cell or battery for supplying power to the vaporizer; and

    a power regulation system for compensating for variation in a voltage level of the power supplied to the vaporizer by the power supply using pulse-width modulation, wherein the power regulation system is configured to set a duty cycle for controlling power to the vaporizer based on a measured voltage output level from the power supply, thereby providing a more consistent output level of vaporized liquid for inhalation by the user.
