I have used regulated / variable voltage/wattage mods with all sorts of toppers and wrapped tons of micro coils in rebuildable atomizers on those mods with resistances ranging from .8 to 3 ohms. There is simply no comparison to sub ohm builds on a mech mod for vapor production. Sub ohm is a whole different galaxy of vapor and vaping experience.
You can however get a DNA 20 regulated mod, and push your wattage up very high to produce the vapor you want. That would be safer and less work than sub ohming.
If you intend to sub ohm for the heavenly vapor, you MUST follow all the precautions and safety measures. The following cannot be ignored or sacrificed:
1) buy a quality multimeter
2) buy an ohm meter built for atomizers
3) buy a good quality mechanical mod that is sized for a 18650 battery
4) buy four (yes 4) of the following batteries:
AW IMR - 18650 1600mah 24A (15C)
or
Sony - SE US18650VTC3 1600mAh 30A (18.75C)
or
Samsung - INR18650-20R 2000mah 20A (10C)
or
MNKE - IMR18650 1500mah 20A (13.3C)
Please do not skimp and try to find the cheapest deal on your batteries. Buy the expensive ones from a reputable US dealer.
UNDER NO CIRCUMSTANCES SHOULD YOU EVER SUB-OHM WITHOUT AN UNDERSTANDING OF OHM'S LAW and a thorough reading of the threads and how-to's here on ECF. I can't stress this enough. If you like to study and learn new things, and enjoy tinkering, sub-ohming may be for you. Think of it like getting a drivers license - you need to be sure you understand how to operate the vehicle, as well as know all the laws and potential dangers before you get behind the wheel.
