Hello all, im new to this so i got a smok al85 and a samsung q30 battery. So i got some spare 0.2 ohm coils and im trying to do the math to figure out the wattage i can use. Id prefer the lower wattage because im using the 0.4 coil now and 40W is great. So they gave me 0.2's and im just a little concerned. Thank you for your input.
