When I was experimenting with TC I used three mods, a sigelei 150, a DNA40 and a DNA40 clone. I have no idea how accurate the power was compared to what I set but all three mods vaped the identical atty the same way at 35-40 watts as far as I could tell. In that range I can tell the difference if I change the power by about 2 watts, or 5%.
That surprised me, I thought there would be more difference between them, specially the clone.
