What is the different  between Single Coil vs Dual Coil configuration? Pros and Cons of Single Coil vs Dual Coilos? how to choose Single Coil or Dual Coil?

Overview of Single Coil vs Dual Coil

        Lets begin our discussion on Single Coil vs Dual Coil by explaining basic structure of  e-cigarette vaporizer. No matter what type of atomizer, cartomizer, or clearomizer you have they all have three basic elements:
--1.Nicotine E-liquid tank or reservoir. Atomizers hold the least amount of e-liquid, while clearomizers and cartomizers have much higher capacity for e-liquid.
--2.Base with a thread to connect battery to a heating element
--3.Heating element or coil. Some models and types of atomizer, cartomizer, or clearomizer come with Single Coil or Dual Coil configurations.

       So what is the difference between Single Coil vs Dual Coil configuration? Is one better than another? A simple answer would be, it all depends on your preference. Although each configuration has its pros and cons, it all comes down to how you vape. To help you better understand the difference between Single Coil vs Dual Coil,  we will go through basic designs and explain how each configuration works. We will also discuss pros and cons. However, once you know and understand the concepts of both configurations we would still recommend trying for yourself Single Coil vs Dual Coil e-liquid delivery device.

       When you say word “coil” we refer to a heating element in your e-cigarette atomizer, cartomizer, or clearomizer. Any E-liquid device on the market today has such heating element inside. A heating element or a coil is a looped resistance heating alloy wire. One side of a coil is connected to a positively charged terminal, and the other side of a coil is connected to negatively charge terminal. When electricity is delivered from your battery to the coil, it heats e-liquid to a point of vaporization. Dual Coil configuration works exactly the same way as a Single Coil configuration, the only difference is that it has two coils instead of one. In other words, power is delivered to two coils, which transfer heat to e-liquid to vaporize it. However, in Dual Coil configuration the power (or wattage) is split equally between two coils. To use car analogy think of Single Coil as a front wheel drive car where energy from the engine is transferred only to one axel. On the other hand, Dual Coil is more like all-wheel drive car, where energy is split between front and rear axles.

Single Coil vs Dual Coil Configurations


 


Pros and Cons of Single Coil vs Dual Coilos:

 

Pros

Cons

Single Coil

 Single Coil configuration tend to consume less battery power. People tend to run Single Coil configuration at lower power output (or wattage) compared to a Dual Coil configuration. On average it saves you anywhere from 10-30% of battery power.
  All things equal, e-juice consumption with Single Coil is much lower. Since, only one coil is in contact with e-juice, you will go thought same volume of e-juice slower.

  Density of vapor produced by a Single Coil configuration is usually lower.
  Although the time difference might not be significant enough or noticeable, Single Coil requires longer heating time.

Dual Coil

  Dual Coil configuration typically produce higher amount of vapor. The reason for that is the amount of contact area between e-juice and coils. Two coils immersed in e-juice transfer heat faster and to larger volume.
  Overall, Dual Coil configurations tend to deliver same amount of vapor in a shorter time. Same principle applies; two coils transfer heat faster than a single coil, therefore, heating time is lower.

  Battery depletion is typically higher and faster.
  E-juice consumption is also higher. More juice is vaporized in order to produce a thicker cloud of vapor.
