1. An apparatus embodied as an aerosol delivery device or a cartridge for an aerosol delivery device, the apparatus comprising:

  • a housing defining a reservoir configured to retain aerosol precursor composition;

    a heating element controllable to activate and vaporize components of the aerosol precursor composition; and

    power harvesting circuitry including an accumulator and a resistor, the power harvesting circuitry being configured to receive radio-frequency (RF) energy from an external RF transmitter, and harvest power from the RF energy to charge the accumulator, the power harvesting circuitry being configured to power or charge at least one electronic component including the accumulator being configured to discharge current through the resistor, the resistor having a variable resistance and thereby the current having a variable amperage that effects a variable wattage, and in at least one instance the resistor being or including a potentiometer.
