Coil Resistances
Coils are available in many different resistances. The resistance you choose to use will impact which power setting or wattage you’ll need to set your device to. If you prefer a lower wattage, you’ll need a higher resistance coil. If you’d rather have a higher wattage, you’ll need a lower resistance coil.
Your resistance choice will also affect which liquid type you can use.
If you want to use a lower power/higher resistance coil, you’ll be restricted to using thinner (50VG/50PG) liquids.
While using a higher power/lower resistance coil will mean you can use thicker (70VG/30PG) liquid.
A rule of thumb to use is “The lower the resistance, the higher the power. The higher the power, the thicker the liquid”.
