I always wonders how to build my vape coil and today I tried it. First I tried to make dual parallel with 4 wraps build but I think my mod were unable to handle it and it is heating up. I tried another build which I use dual coil with 7 wraps. It is successful for me because my mod doesn’t heat up and the vapor coming from my atty is nice. Well..I can say that I’m satisfied with my first build.
