An electronic cigarette vaporizer that includes a heating element, a power source and an electronics module that manages the delivery of power, current or voltage to the heating element； the electronics module controls or delivers pulses of power, current or voltage to the heating element, such as PWM (pulse width modulation) with a high frequency 1-10 KHz switching frequency. The duty cycle of the PWM can be approximately 90% when heating； and 1-10% duty during a preheat； and 0% when the vaporizer is idle.
