Is that 15 watts regulated or unregulated?
I'm really liking the coils I have right now. Nano tank on Pico. New mod so this is only the third coil I have built for it. This is second at same ohm, other was 2.5id. Went bigger to improve wicking.
1. Nichrome 32x4 twisted to 1mm pitch
2. 6 (.6ohm)
3. 3mm
4. Cotton Ball
5. bouncing between 13-15, higher is too warm for me.... might be more flavor there, if there was more airflow and maybe a full size chimney/tank.
My 3.1 has a 1.3ohm coil don't remember build. But it is making my wifes juice vapable, at around 13 watts. Must have wicked it with silica.... Didn't get burned cotton taste when I hit it at 40watts. Just dry burned coil taste. Have to try some of my juice in it.
On my Mech, dual air fastfech clone base, have a .9ohm coil, 2x31 Kanthal on 2.5mm, cotton ball.
I only use 28 and smaller wire and prefer twisted wire builds. Until 3 weeks ago only had Mechanical mods. Generally run my Kayfuns at .9ohm to 1.4ohm, with a heat flux average around 150, between 5 and 7 wrap coils on 2.5id. Mostly use cotton balls but also run silica. Silica give better flavor, YRMV, but can be harder to get setup. Unless you wrap on wick. Good thing is, it lasts the life of the coil. No rewicking, just dryburn and vape-on.
