I am using a Kayfun on my SVD. The lowest OHM coil I have been able to get my SVD to consistently fire at is .9 ohms. I have my SVD set to volts and cranked up to 6.0 volt. How may watts does this translate to? The max wattage setting on the SVD is 15 watts. Does that mean the max output is 15 watts as well? The reason I ask is because the juice I am using hits hard at sub ohm and higher watts. I was told that .6 ohms pushing around 30 watts is ideal, if I remember correctly. I am trying to get as close as possible with my SVD. When I can justify buying a mech mod I will and this will no longer matter. What is the max wattage out put my SVD will fire if I have a .9 ohm coil, 18650 battery set at 6.0 volts? Is it regulated to 15 watts? Or what? Any advice on sub ohm vaping will be helpful. I am 7 weeks off analogs and vaping has saved my life! Thanks
