    Can anybody offer any tips/advice on the reasoning, methods and differences between power and temperature modes? I’m lucky if I can operate the thing to switch modes, much less knowing what is going on when I do.


    • Vic says:

      Using Temp Mode regulates the power for you. In wattage mode you are just heating your coil and making it red hot.
      Temp Mode will regulate the temp of the coil for you, not let it fire red hot all the time.
      Temp Protection means your coil is at the temp, and it is being protected from overheating.

    I’m having a slight issue with the triple coil. I set it to ti, 25w and 400 but it doesn’t heat up enough to vaporizer product. I need to turn it up a bit more to get any smoke.

    When replacing the ceramic donut how do I get back NI mode ?
