Abstract: A vaporizer power assembly includes a cartridge interface, a battery, a radio frequency communication interface, an output, an input and a microcontroller. The microcontroller is configured to transmit power and/or heat from the battery through the cartridge interface in accordance with one or more signals from the input and cause the output of the vaporizer power assembly to emit a presence indication in response to receiving a presence indication request with the radio frequency communication interface. A case housing or partially houses the cartridge interface, the battery, the radio frequency communication interface, the output, the input and the microcontroller.
