The Eleaf GS Drive tank is a compact 2ml top-filling tank with a child-safe design. To fill, press a button, push the top cap where indicated, and insert your e-liquid nozzle into the fill hole. Close the cap and let it soak for 2-5 minutes to avoid coil burning. 

Coils ranging from 1.5Ω to 0.35Ω for MTL and DTL options can be replaced from the bottom without emptying the tank.

Adjustable airflow at the base allows customisation, and removeable 510 mouthpiece can be replaced as needed.
