Dual coil (mega)cartomizers, clearomizers, tank-cartomizers

You can use it at 4.6 V but it's quite close to the limit. I'm not sure you have any need to use the dual coil, but if that's what you find to be your sweet spot, so be it. At these values, your amperage will be 3.06 Amp (limit is 3.15 Amp).

In any case, I would try a higher resistance single coil cartomizer, and one of the newer clearomizers maybe you find your sweet spot elsewhere. With a dual coil, the total power fed into the carto is divided to the two coils. In your scenario - 14.1 W total => ~7 W / coil, that is a pretty good vape. However, if you want even a little more power per coil - as most people's sweet spot is between 7 - 9 W, some people even higher - then you can't really do that with a dual coil. If you were to chose a 3 Ohm vapor head then you could push it all the way to 6 V and get a power of 12 W all into the coil - just for reference, 12 W is way to high for me, for instance, but others like it.

However, your total power output will be 12 W, so the battery drain will actually be slower than on the dual coil at 7 W/coil, and it will last longer and be marginally safer.

Here is a list of the limits for the ProVari: http://www.provape.com/v/images/ProVariV1vsV2.pdf and a handy tool to calculate those values from your resistance and voltage: Ohm's Law Calculations With Power

OMG! You zombified one of my very first threads on this forum! I think the second! Jeez.. you got me all nostalgic now!


I am so indebted to this forum and to all the people who helped me make it this far!

You'll still be able to use the 1.5 ohm carts, but the voltage range will be limited before you get the E2 error. 2.5 - 3 ohm will expand the available range as you probably already know.

elfstone & Flyer, thank you so much - those explanations actually make sense, I think I get it now - thanks for the attachments, most appreciated.

The general consensus is that dual coil cartos drain the battery faster, but my lack of engineering knowledge is giving me a hard time understanding why. Regardless of the number of coils, shouldn't a 3.7v battery deliver the same number of watts to a 2.0ohm atomizer, even if split afterwards between the coils?

I'm not trying to argue against the advice already provided by this thread and so many others before it. I just want to understand exactly how it works if any of you vets or electrical experts care to shed some detailed light on the subject. Thanks!
