Im measuring by looking at screen counter.
On 20w istick using a dripper at 1.30hm it fires at .1sec on any wattage up to 20 watts
On 30w and 50w istick using a dripper at 1.30hm it fires at .1sec on wattages up to around 14 watts
After that around 15 watts higher it fires around .2-.3 secs
Same thing for subtank mini at .5 ohm on 30w and 50w istick
I'm listening to coil as soon as hear any slight sound.
There is def a slight delay compared to the original istick 20w and newer 30w and 50w isticks after about 15 watts power setting.
Are you sure the coils are exactly the same. Same gauge same amount of wire? Ohms doesn't matter as much for heat up as wire mass does. Two coils having different gauges or a single to a dual at the same ohms will heat differently.
32g say 8 wraps heats instantly at 15w, dual 32 & single 28g slower, it would take 30w to heat dual 32 & 28 as fast as the single 32 at 15w. A 26g is even slower/ more power needed, probably about 45 to get instant heat up.. If you already sorted that, apologize.
