  • the electrical power supply may include a battery or a rechargeable battery.
  • the electrical power supply is connected to the positive terminal 1037 and the negative terminal 1035 of the electronic cigarette 10 through one of: a T-shaped groove connector, a dovetail shaped slot connector, a magnetic attachment connector, a threaded connector, and a multi-threaded connector.
  • the electrical power supply is connected to the electronic cigarette 10 through a threaded connector, or a multi-threaded connector.
  • the user presses one or more push button switches to turn on the electrical power supply connected to one or more heating elements 1043 according to the desired amount vapor the user wishes to have, one push button switch corresponds to one heating element.
  • the user sucks E-liquid vapor from the vaporizer assembly 102 through a mouthpiece 1011.
  • Air outside of the electronic cigarette 10 enters the vaporizer assembly 102 through an air intake adjustment ring 1025.
  • the air intake adjustment ring 1025 defines a first air intake opening 10251 and a second air intake opening 10252.
  • the air intake adjustment ring 1025 is rotatably positioned outside of an air chamber body 1026.
  • the air chamber body 1026 defines a first air chamber opening 10261 and a second air chamber opening 10262. The user may rotate the air intake adjustment ring 1025 to adjust the air intake to the air chamber body 1026.
  • the air intake adjustment ring 1025 is adjusted to a maximum position so that the first air intake opening 10251 and the second air intake opening 10252 coincide the first air chamber opening 10261 and the second air chamber opening 10262 of the air chamber body 1026, respectively to allow maximum air flow into the air chamber body 1026.
  • the air intake adjustment ring 1025 is adjusted to a minimum position so that the first air intake opening 10251 and the second air intake opening 10252 overlaps the first air chamber opening 10261 and the second air chamber opening 10262 of the air chamber body 1026 partially to reduce the air intake to the air chamber body 1026 to its minimum.
  • the air in the air chamber body 1026 is vaporized by the vaporizer assembly 102, and vapor formed by the vaporizer assembly 102 exits through the mouthpiece 1011.
  • the method also includes: removing, by the user, the volume adjustment ring from the E-liquid storage tank to obtain maximum E-liquid capacity of the E-liquid storage tank.
  • the method may further include: removing, by the user, the electrical power supply from the electronic cigarette for replacement or recharging.
  • the E-liquid storage tank includes: an E-liquid refill base, an E-liquid storage tank internal wall, an E-liquid storage tank external wall, a vaporizer assembly mounting base, and a volume adjustment ring.
  • the E-liquid storage tank is sealed by a first mouthpiece sealing ring on the top, and a vaporizer sealing ring at the bottom.
  • the volume adjustment ring is installed inside the E-liquid storage tank between the E-liquid storage tank internal wall and the E-liquid storage tank external wall to reduce the amount of E-liquid filled in the E-liquid storage tank.
  • the thickness and the height of the volume adjustment ring may vary to adjust the amount of E-liquid in the E-liquid storage tank.
