The subject of Single Coil VS Dual Coil build configuration for vaping devices is a topic that triggers many debates among the vaping community.
Single Coil VS Dual Coil Vapes
Many vapers tend to be captivated by other features of a vaping device like e-juice flavor, tank style, and battery color. Although it may not be as thrilling as discussing the newest and most sophisticated vape mods, talking about coil build configuration can help vapers gain basic knowledge on how to attain the best vaping experience.
Your coil configuration affects everything about your vape.
Understanding the differences between single coil and dual coil configurations is imperative since atomizer coils have a significant impact on the vape experience. A vape mod really only does one thing… It supplies power. The atomizer coils inside your rebuildable do the rest. Your coil configuration will determine the following:
- Cloud Production
- Flavor Production
- Battery Longevity (Battery Life)
- E-Liquid Consumption
- The temperature of the Vape
In this guide we will address each aspect and how the number of coils plays into each of these. By the end you will have a good idea if you should be seeking a single coil or dual coil configuration and beyond.
Coil Build Basics
An atomizer coil is the heating component found in your rebuildable, clearomizer, pod cartridge or cartomizer. Most vaping devices have one or two coils, and some have three or even four. These different coil builds function quite similarly to the battery on a vehicle. One end of the coil wire is connected to a positive charge post while the other end is connected to a negative post. Once the vaping device is heated up, the current moves from the battery to the atomizer coil thereby heating up the e-juice until vaporized.
Let’s jump into single coils first.
Single Coil Configuration
In this atomizer coil configuration, the battery of the vape heats up the e-liquid by transferring all power to a single coil. Single coil build configurations are easier to set up because they only require one coil and not two coils with matching resistance.
The clouds produced by a single coil are usually less than a dual coil configuration. This is because there is less wire and that means less surface area in contact with the e-liquid.
If you’re going for a stealth vaping build single coil is a good place to start. Normally, the vapor generated by this kind of configuration is less dense.
The Flavor on a single coil configuration is usually better and more flavorful than on multi-coil setups. E-juice flavor is in most cases easier to detect at a lower wattage. This is because single coil builds require less power and produce less heat. Some flavors do come out at higher temperatures but for the most part, it’s easier to taste e-liquid flavor on a cool vape.
Battery Saving Properties. Because there is less surface area on one coil as opposed to two, less power is needed in order to ramp up the coil to a vaporizing level. This means that one coil will heat up faster, and use far less power to maintain the correct vaping temperature.
Single coil configurations utilize 10 to 30 percent less battery power compared to dual coil configurations.
When there is less wire in contact with your cotton, this limits the amount of e-liquid that can be vaporized on each draw. Using a single coil setup will reduce the amount of e-liquid consumed on each fire. Overall, it will consume less e-juice but may require the use of higher nicotine concentration.
Temperature of the Vape
Single coil configurations require less power. For the most part, less power means less heat. With one coil your vape should taste much cooler.
Due to their simpler set-up, single-coil configurations are ideal for beginners. Rebuilding requires you to only have to produce one coil instead of two.

Dual Coil Configuration
In dual coil set-ups, the battery of the vaping device uniformly distributes power to two coils that concurrently heat up the e-juice and convert it into vapor. Dual coil build configurations are slightly more difficult to setup. They require you to build two coils with matching resistance. In addition, some build decks only have two poles which make it harder to install the coils since the coil leads have to share post holes.
Since there is a larger surface area for e-juice to come in contact with the coils, dual configurations offer much more vapor compared to single coil set-ups. They are a great choice for cloud chasers since they produce much denser vapor.
A dual coil configuration is instrumental in providing a stronger throat hit since it delivers more vapor. Therefore, such configurations are ideal for individuals who are transitioning from smoking to vaping and are looking for a larger punch of nicotine at a lower nicotine percentage.
When you run multiple atomizer coils you need more airflow to benefit from all the surface area that the wire can vaporize. The atomizer chambers also tend to be a bit larger and require larger airflow. These are two big killers of flavor, airflow, and bigger build deck chambers for that Airflow.
The flavor on a dual coil build will in most cases lack in comparison to single coil configurations. When air mixes with the vapor it decreases the concentration of the flavor profile.
Two coils have more surface area and lower amperage. These two factors require more power to heat up the coils. The power needed drains the battery power at a faster rate than a single-coil configuration.
If you plan on running dual coils it is recommended that you purchase a box mod with dual battery capacity or greater. You can run dual coils on a single battery but it most likely will not get you through the day.
If you decide to choose dual-coil technology, you should keep in mind a few considerations. For example, vapes with dual coil set-ups tend to consume e-liquid much faster. More surface area means more vapor but may lead to as much as five times greater e-liquid consumption. This is because more e-liquid is exposed from the cotton which is in contact with the wire in your build.
Temperature of the Vape
Because you are using more metal which requires more power it translates into more heat. It is definitely a hotter vape than a single coil. This is also why it is required to have a more open airflow.
If you are running two or more coils it is advised to stay away from any metallic drip tips. These can get very hot!

These are the differences between Single Coil Vs Dual Coil. Below are some helpful tips involving wires that can be used with either configuration.
Which Materials Are Ideal for Coil Building?
Any vaping enthusiast wants to build his or her own coils and enjoy an unrivaled vaping experience. Before you start the coil-building process, it is imperative to have a clear understanding of the various coil-building materials. This knowledge will allow you to make a wise decision on the best material for your vaping needs. Flavor quality and vapor production capabilities vary depending on the type of coil building material. The 5 common forms of vaping wires include:
- Stainless Steel
These wire types share the following similarities.
- Gauge: This is a number that depicts the thickness of your wire. In fact, it represents the diameter of your wire. The greater the wire gauge, the smaller the diameter. Therefore, a 32-gauge wire will have a smaller diameter compared to a 24-gauge wire.
- Resistance: It refers to the opposition to the movement of electric current. The wire is heated up through this process, allowing it to turn the vape juice into vapor. High gauge wires tend to have a greater resistance and heat quickly, enabling them to provide quality flavor and adequate vapor at lesser wattages.
- Ramp up Time: This represents the duration taken by your coil to warm up to a temperature that can convert vape juice into vapor.
Types of Coil Building Materials
When building coils it is important that you don’t build a configuration where you plan on using a wattage that will exceed your battery’s recommended amp draw. Here is a helpful ohms law calculator.
Kanthal (Most Common & Universal Wire)
Usage: Variable Wattage
Most premade coils are made using this wire. It is ideal for wattage, but it performs dismally when it comes to temperature control. Kanthal is the best coil-building material for individuals who are just starting to use rebuildables since it is easy to work with, cheap, and locally available. Due to its stiff nature, it doesn’t lose shape when used to make atomizer coil loops.
Usage: Variable Wattage & Temperature Control Mode
These wires are exceptional due to their ability to support TC mode and wattage vaping. They are alloys constructed using chromium, nickel, and carbon. They are easy to work with and hold shape easily. They also have a quicker ramp-up time compared to Kanthal.
Usage: Temperature Control Wire Mode
These coil-building wires are manufactured using pure titanium that is well matched for TC devices. When heated to more than 1200F, titanium releases toxic titanium dioxide that can put your health at risk. Apart from being easy to work with, titanium wires hold shape well. Titanium produces a clean, crispy flavor.
Usage: Temperature Control Wire
This unique alloy is a blend of nickel and chromium. It functions almost similar to the Kanthal wire, but it has a quicker ramp-up time. It has less spring than Kanthal, but it still maintains shape perfectly, which simplifies coil building.
Usage: Temperature Control Mode
Commonly known as Ni200, Nickel wires consist of pure nickel. These wires are readily available locally. Nickel is a perfect choice for temperature control devices. It produces a delicious flavor and makes the vaping experience better.

You should now have a better idea of what you’re looking for in your next RTA, RDA, or RDTA. Enjoy some of our best-of lists where we describe exactly how many coils each topper is capable of.
- Compatible List of RTAs – RTAs have a build deck with a tank to hold E-Liquid.
- Compatible List of RDTAs – RDTAs are like RTAs except the unit is set up so that you can drip from your bottle of e-juice.
- Compatible List of RDAs – RDAs usually have a larger build deck and you used your bottle of e-juice to directly drip onto the coils.
While navigating towards the ideal vaping experience, every vaper comes to the point of selecting the best coil set-ups. The ability to differentiate between single coil vs dual coil set-ups can come in handy during such points. Vapers looking for bigger clouds should go for the dual coil configurations. Those who want to build their own coils with stronger flavors should go for the single coil configurations, which are usually easy to build. Vapers who haven’t made their mind yet should try both configurations to gain an in-depth understanding of the difference.
