Vape Coils: How They Work, What You Need To Know, and Research

Whether you’ve recently taken to vaping or are already hooked to the habit, you’ll find yourself replacing your vape coils from time to time. When that time comes, you’ll realize that finding vape coils perfectly suited for your vaporizer isn’t exactly a walk in the park.  

But since vape coils don’t come cheap, it’s essential to familiarize yourself with everything there is to know about these attachments. This post highlights what vape coils are, how they work, and what you need to know before buying them. 

What Are Vape Coils? 

To understand what vape coils are, we should probably begin by highlighting the various components that make up the anatomy of a vaporizer. A vape device comprises the following parts: 

Vape tank 

The vape tank is the chamber that holds your vape material in place. Vape tanks come in various shapes and sizes, depending on the design of your vaporizer and the specific vape materials you intend to use them with.  


A vape battery simply refers to the device that holds power required to fire your e-cig.  


The mouthpiece of a vaporizer is the uppermost pointed part through which you draw heated vapor from the device to your mouth. It’s also known as a drip tip. 


Coils are the most functional part of a vaporizer’s heating chamber. Technically known as an atomizer head, a vape coil is a special thin wire whose principal role is to propagate heat generated by the rest of the heating chamber to the vaping material in the vape tank.  

Choosing Vape Coils 

The primary consideration when looking for vape coils is to establish the reputation of the seller. This step is necessary as vaping is still a relatively new industry. So, there are considerably high risks of buying low-quality vape attachments. Fortunately, you can always choose high-quality Vaporesso coils or go for vape coils by other reputable retailers.  

But how can one know that they are dealing with a trusted vape coil supplier? You can establish a vape coil supplier’s reputation by checking the duration they’ve been in the market. The longer their industry presence, the more likely it is for the retailer to offer high-quality coils. Another way to know you’re dealing with a reputable vape coil supplier is by checking the nature of their online reviews. These reviews will clue you in on the quality of coils the supplier deals in as well as the expected customer experience.  

In addition to seller reputation, coil material is another factor to consider while choosing vape coils. Vape coils are typically made from metal. And there’s a wide range of metals that manufacturers can experiment with. However, experts recommend coils made from Kanthal or Nichrome.  

Kanthal is a metal alloy consisting of iron, chromium, and aluminum. It goes by the chemical formula FeCrAl. Nichrome is an alloy of chromium, nickel, and sometimes also iron. Its chemical formula is NiCr. Kanthal and Nichrome are preferred due to their low resistance and high heat conductivity. These metal alloys are also free of the signature metallic taste, adversely impacting your vape juice flavors.

How Do Vape Coils Work? 

Vape coils may have undergone a remarkable evolution since the invention of the first modern vaporizer. However, most coils function in a near-similar manner.  

The following is a brief overview of how vape coils work; 

Screw the coil onto the vaporizer. 

This step is only necessary for vape devices that come with detachable coils. If your vaporizer comes pre-assembled, then you can ignore this bit. 

Fire the device. 

Each vaporizer comes with an On/Off button that you press to turn the device on or off. When the device is turned on, electric power transfers from the battery to the heating chamber, where it converts into heat energy. The coils propagate the heat generated from the heating chamber to the vaping material using a wick.  

The heat transfer is aided by a single wick or a series of wicking materials. It can happen directly through the conduction method or indirectly through the convection method. 

Take your draws. 

The action of drawing from a vaporizer’s mouthpiece not only gets heated vapor into your mouth. It also creates a temporary vacuum in the heating chamber. Air rushes into the device to fill the vacuum. With the vaporizer still fired and more air flowing into the chamber, the coils continually heat up and produce more clouds. This is where the aspect of coil resistance comes in.  

Vape coils have electrical resistance measured in ohms (Ω). There are high-resistance coils with resistance above 1.0 ohm and low-resistance coils (also known as sub-ohms) with a resistance below 1.0 ohm. High-resistance coils are suitable for vaping at lower temperatures. They deliver smaller clouds of vapor, utilize less e-juice, and can work with most standard vaporizers.  

On the other hand, sub-ohms are perfect for vaping at higher temperatures. They produce vast clouds of vapor, utilize more e-liquid, and are not suitable for all vaporizers.

Final Word 

Remember that even the best-maintained coils will need replacing on a long enough timeline. Ideally, you should replace your vape coils when you start to experience a burning taste, gurgling sound, or reduced vapor production. Above all, remember to bring yourself up to speed with your local vaping laws before owning or using any vape device.
