Hi everyone, I started vaping with a vaporfi pro 650 mAh battery with an atty at 1.8- 2.0 ohm. Then I upgraded to a provari with a carto tank from IBTanked, which I LOVE!!! I tried a friends Atlantis and it was so harsh I couldn't believe how hot it was. I actually couldn't get into my lungs choked me up bad. So I bought a subtank mini the other day and tried the 1.2 ohm coil with my provari and again way too hot and harsh. I tried it at the lowest volts and not much vapor and the higher I went the more vapor but couldn't enjoy it (get it into my lungs) I really would like to blow big clouds but how the hell do you do it??? What am I doing wrong?
IMO it would be a lot easier to achieve what you are looking for with a rebuildable atty with good air flow to allow a cool vape at higher power. You also need the appropriate wire and coil design to keep the watts per square mm of coil surface area (heat flux) low and thus cool.
For example, I sometimes run a
Mutation X RDA at 0.20 ohms with a dual coil build using 24 gauge Kanthal on a mechanical mod. The Mutation X has 18 air holes and they are not small, so there is no lack of air flow
. This setup makes about 70 watts on a fresh battery. Here it is modeled in
the Steam Engine calculator. Look in the 'Results' window and note the heat flux at 70 watts is 386. I don't consider that warm, but I think you might.
With a regulated mod you can turn the power down without building new coils. If you change the watts beside the heat flux to 40 the heat flux changes to 221, which would be way too low for me but you might like it, or you might like 45 watts, or 50 watts.
The thing is once you find a good heat flux number for the style of vaping you like that will be a guide you can use for other builds in future.
With a regulated mod you also do not need to go as low in resistance as I do.
Here is an example of a 0.8 ohm dual coil build using 28 gauge Kanthal that has a heat flux of 388 at 70 watts, almost the same as the first setup.
This works with any power level, so if you chose to vape at 10 watts start there and find the setup that gives you the heat flux you like. The heat capacity number comes into play for coil warm up time, but I've found that it mostly takes care of itself if I have the heat flux right.
Keep in mind also that the more power you put into the atty the faster you will have to inhale to keep the vape cool.
