Dual Coils Explained

[Jimi D.]

The best overall vapor I get is with a dual coil Cyclone AFC. .8 ohm with a mech. Heaven !

I think when you say that a single 8watt coil will vape exactly the same as a dual coil setup at 8 watts is not exactly true.

I'm pretty sure I never said that.

Assume that with these settings, you find that your vaping experience is quite pleasant. You then remove your single coil device and put your 2 ohm dual coil device on your PV. You still have the PV set to 4 volts. You then take a draw from your e-cig, only to find that your vapor production is actually not any better than it was on the single coil! This is because instead of having 8 watts pumping through a single 2 ohm coil, you now have 8 watts divided up evenly between two 4 ohm coils. In other words, you now have 2 coils set at 4 watts each.

The power gets divided up between these coils because the current gets divided up between these coils. The total current IT of 2 amps is going to be the same as it was with the single coil delivery device due to the fact that our PV is still set to 4 volts and it is still reading our delivery device total resistance as 2 ohms. However, now that you have two coils this current gets divided up between them. In other words, each coil is now only receiving 1 amp.

So what does this all mean?
If you are vaping on a dual coil device in the hopes of achieving double vapor production, you will have to double the power output of your PV. Remember that we enjoyed vaping at 8 watts through a single coil. If we are using a dual coil device and want to push 8 watts through each coil, our PV will have to be set to output 16 watts (*Note that some PVs will not allow a power output this high but stick with me here). Not everyone uses variable wattage devices though, so we need to determine which voltage setting would yield the equivalent of 16 watts so that we can achieve 8 watts through each coil.

you don't actually say that but here it seems implied that the only way to take advantage of the dual coils is by doubling the power or it won't be much different. you say "You then take a draw from your e-cig, only to find that your vapor production is actually not any better than it was on the single coil! " also seems to imply that there will be little difference unless you up the power significantly.

the only point I'm trying to make is your post addresses all the electrical aspects of dual coils, which treats a dual as being equal to a single of the same resistance, but it doesn't really address the differences in the vape.



why is a dual coil different from a single coil? explaining it electrically and then in conclusion say "it's up to you" doesn't really explain the difference in the vape of a single coil vs a dual coil setup. why are they different in performance even at the same power level?


I'm sorry bro, I just expected that "dual coils explained" should probably explain the real differences in vape and performance, you only explained half the story

Thanks for the feedback, though I stand by my statement that a dual coil at 8 watts will not significantly improve over a single coil at 8 watts due to the 8 watts being divided evenly between the 2 coils (4 watts through each coil). Also note that I specifically said that many people find that they do *not* have to *double* their power output to achieve desirable results. That being said, every single time I use a dual coil my power is set higher than it is for my single coil devices. Nonetheless, the purpose of my post was to simply explain dual coils from a technical standpoint (admittedly I could have been more clear about that).
