Vape Coils Explained: The Ultimate Guide for Beginners

For many, the vaping world can feel perplexing at times. With a vast array of specialized terms, a multitude of devices, and numerous vaping styles, the options may seem overwhelming.

In this article, we’ll delve into coils, one of the essential yet simplest components in any vaping setup!

What is the functioning of vape coils?

Coils, often called atomisers, are the part of your vaping device responsible for generating vapour.

They consist of three main parts: the heating element, the wicking material, and the casing. The casing holds all components together and facilitates easy installation in your tank or pod.

Typically made of organic cotton, the wicking material draws in e-liquid and supplies it to the heating element.

The heating component, commonly known as the coil, is crafted from resistance wire, formed either into a traditional coil or made from strips of resistance mesh, referred to as a mesh coil.

Upon pressing the power button on your vape and inhaling, the coil heats up, causing the vaporized e-liquid to blend with air, resulting in vapour. The heat induces more e-liquid to flow into the coil from the wicking material, which concurrently draws additional e-liquid from your tank or pod.

This operation hinges on a delicate equilibrium between heat and wicking efficiency, which is why significant effort goes into meticulously fine-tuning

What are the various types of coils?

MTL/“mouth-to-lung” coil

MTL, or “mouth-to-lung,” coils are crafted to mimic the sensation of smoking a conventional cigarette, featuring a tight draw and low power output. Typically, MTL coils are intended for use with e-liquids that have higher nicotine strengths to further enhance the “throat hit” associated with cigarettes.

One can easily identify a coil head designed for MTL vaping by examining the diameter of the coil within. MTL coils have a narrow bore, allowing for very tight airflow while maximizing flavor output even at lower wattages.

Usually constructed from standard round wire, MTL coils are well-adapted to lower power output. Since they are meant for low power levels, it’s crucial not to exceed the specified wattage range. Innokin coils always display their recommended wattage range, so be sure to consider this before increasing the power!

An example of an MTL coil is the Prism series coils, which are compatible with the Innokin Endura T22 Pro.

 

DL/“direct-to-lung” coil

DL, or “direct-to-lung,” coils are engineered for high power, substantial airflow, and significant vapor production. Nowadays, most DL coils utilize strips of mesh instead of the conventional round wire.

A coil head designed for DL vaping can be identified by the diameter of the coil inside. The wide bore of a DL coil facilitates maximum airflow, vapor production, and heat dissipation. Generally, DL coils have a recommended power output starting at 40W and above.

Examples of DL coils include the Z-force coils that are compatible with the Innokin Kroma 217 kit.

Positioned between MTL and DL coils, RDL coils serve as an outstanding option for vapers looking to enjoy intense flavor and enhanced vapor production while also conserving battery life and e-liquid usage.

RDL coils, with their middle-range power needs, can be designed using either traditional round wire or mesh strips. On average, they are best suited for a power output of 20-40W.

An example of an RDL coil would be the 0.3Ohm Z-coil, which is compatible with the Innokin Coolfire Z80 kit.

 

What’s the Difference Between Round Wire and Mesh?

Round wire coils and those made from mesh strips are both widely favored, but how do they differ, and which should you choose?

Round wire is generally utilized for coil heads that operate at lower wattages due to its effective performance at lower temperatures. Additionally, manufacturers can easily adjust performance with variations in wire thickness or the number of wraps.

Conversely, mesh strips are typically used for coil heads designed for medium and high wattages. The rapid heating capability and extensive surface area of mesh coils make them suitable for e-liquid absorption at elevated temperatures. Moreover, mesh coils usually exhibit lower overall resistance for their mass, potentially stressing smaller batteries intended for lower output.

 

DuoPrime – A Revolutionary Leap in Coil Design

At Innokin, we continuously strive to enhance the vaping experience. As previously noted, mesh coils excel in facilitating e-liquid absorption.

What if we could further boost wicking efficiency utilizing mesh strips?

Our engineers came up with the DuoPrime technology concept. This innovation incorporates an outer layer of mesh positioned between the wicking material and the inner coil.

This outer mesh layer heats at a slower rate, yet it sufficiently draws e-liquid into the coil quickly. This innovation revolutionizes coil design, significantly improving coil longevity, saturation, and flavor output.

You can experience this groundbreaking coil design firsthand with the inaugural DuoPrime coils, now available in the Z-force Tank, part of the Kroma 217 kit.
