Single Coil vs Dual Coils

One of the big questions that tends to divide Vapors, is the age old question of single coil or dual coils.

And to be honest there is no one set up that is best! And as with many areas of vaping it comes down to your own personal preference.

But when decided whether to have a single coil or dual coil, there are a few things to bear in mind.

Power Usage

Double the coils, and you double the power consumption. So if your looking at getting the more vaping time out of your battery, then you may want to consider sticking to the single coil builds. As simple rule of thumb is bigger the build then bigger the power consumption. I tend to find that switching between single and dual, will literally half your battery life.

Some atomisers have smaller chambers, to assist with intense flavour production. With these small chambers you need to be aware of the amount of heat your coils are producing, as even after a short time vaping of a larger dual coil set up, you will notice the increased levels of heat transfer, from the coils to the chamber wall.

Ejuice Consumption

The number of coils you have wicked up on your deck will definitely effect the amount of juice. A dual coil set up will burn through twice as much E-juice as a simpler single coil set up. As you are effectively sucking up the juice twice as fast.

Vapor Production

The main benefit of a dual coil set up, is the ability to produce more Vapor, whether or not it is double the amount, it is hard to say. But a well build dual coil set up will defiantly chuck out the clouds. You are effectively producing twice the amount of Vapor in the same time, delivering a thick more dense Vapor.


Flavour is one of the hardest elements to quantify, and will again split Vapors. Personally I find that a single coil produces the better flavour reproduction than a Dual Coil set up. I’m not sure what the science is behind it and I’m sure some of you will disagree. But if I’m looking for flavour I will always go for single coil. Not sure if it is to do with the heat levels, or the speed it burns through the juice, I’m not sure.

Ease of Build

Lastly it comes down to ease of building and setting your coils. Obviously a single coil build is a lot easier to work on. When working in pairs, it is important that you get both coils identical, so that perform harmoniously. If one coil is slightly spaced different to the other, you will find that it heats quicker than the other, which will mean that they wick up the juice a different speeds. And you will tend to find that over time one cotton wick will go darker than the other, and caramelise quicker as it is heating more than the other.

Single Coil vs Dual Coil, Final Thoughts…..

As you can see, there are quite a few factors to take into account, some measurable so not, but at the end of the day, as with many things in Vaping, it comes down to personal preference. And just because you may prefer single coil set up on one of your atty’s you may prefer dual coil, on another. For instance I always squonk with a dual coil set up, drip with duals, but prefer a simple single coil set up in my RTA (Rebuildable Tank Atomiser). So I would recommend trying out different set ups, to see what suits your vaping style.
