1)How to assemble

First, Screw the collector-tank in atomizer base.

Second, install wick/coil.

Third, screw evaporation chamber into the atomizer base, then body, cover and mouthpiece in succession.

2)How to adjust the airflow

For the function of adjustable airflow, Kayfun-mini comes with a special screwdriver to assist the operation. Using the bottom part of the screwdriver to adjust the directions of screw in the atomizer head ring, you can easily realize different draws.

Note: The kit comes with a spare screw for the airflow valve. Pls keep them in position.

3) How to fill in e-liquid

Kayfun-mini filling can be done in two ways.

Method 1 (classic):

-Unscrew the mouthpiece and the top cap

-Fill in e-liquid along with the inner wall of the atomizer tube (not through the central hole) Do not fill to the top

-Screw the cap and mouthpiece back

Method 2 (through the valve)

Filling through the valve, you will need a bottle with a thin plastic nose. Nose diameter should be suitable to the filling port.

- Turn the mouthpiece down

- Insert the nose of the bottle in the valve opening.

- Fill the tank by squeezing the bottle. The air will escape from the tank into evaporation chamber through the same grooves.

- Take out the nose of the bottle from the valve, turn mouthpiece on.

4) How to get 6ml capacity

-Replace the short chamber with the long one

-Assemble the plastic tube to the atomizer base and then connect with the steel tube

-Assemble the rest parts and you can get a 6ml capacity atomizer. Done!


  • The atomizer comes with 510 thread. It's compatible with 510/eGo batteries.
  • Find comfortable nicotine level.
  • When you use Kayfun-mini for the first time, try to start from nicotine level twice less than you used to!
  • Find comfortable strength and duration of the draw.
  • When using Kayfun-mini, draw should be different from what you got used to with conventional cartomizers and tanks. It has to be smoother and lighter.
  • Find comfortable power level(voltage, resistance)
  • Power is the ratio of the square of the voltage to the resistance
  • If you have a 2ohm resistance coil, and the battery produces 3.7volt, then power is equal to 3.7/2=6.85watts.
  • Steel color also available
