I've used tank mods with prebuilt coils in TC. Ut have always used wattage in my RDAs mostly be ause Im not sure what material my wire is made of. I pur hased the demon killer 7 in 1 box and it looks like stainless but nowhere on the package or even the website does it say so. I also just got the coilmaster kit and it comes with a spoil of kanthal which ive never used... How can i be sure what material it is or if ig can be used in TC? Not zure if it helps but my mods are the smok alien 220 with the tfv8 tank that i use when im driving my rig. (Also the first mod kit I bought that got me off the 2 pack a day habit) In the warehouse I'm using the Innokin Bastion squonke 100w, and at home im using my new sigelie ravage 230w though i havent used the gnome tank it comes with, sticking with the vandy vape bonza for in home cloud chuckin. I mostly use TC on the smok while im driving so i dont burn out the coils but was looking to see if i can build coils for in home use on the ravage.
