A Beginner's Guide To Vape Coil
A vape coil, also known as an atomiser coil or just an atomiser, is the part of your e-cigarette that vaporises the e-liquid to produce the vapour that you inhale. The coil is one of the most important elements of your vape and other than the e-liquid, it is the part that will need replacing regularly to ensure your e-cig is working optimally and providing great flavour and vapour production.
But what is a vape coil and why does it need changing? Here we’ll break everything down for you so you’ll have a complete understanding of how it all works .
What is Coil ?
Vape coils are the replaceable element in vape kits and tanks. It is the coil that takes the power from your vape battery and turns it into heat, which is then used to turn e-liquid into vapour. Inside a standard coil model, you will find a length of coiled wire wrapped around an absorbent wick.
The wire creates heat, while the wick absorbs the e-liquid held in your Vape vape tank. The two elements of the coil work in combination, with the wick supplying a steady source of e-liquid for the wire to heat into vapour.

E-Cigarette components
vape is made up of a few simple parts:
The battery, the tank, the coil and the mouthpiece
You will find the vape coil inside the tank or pod on your e-cigarette. Most coils are removable and will either screw in or have a push fit design.
Coil Resistance And OHM'S Law
A coil’s resistance is measured in Ohms. Ohm’s Law describes the relationship between current, power and resistance, and is very useful to understand as it directly relates to vapour production, which can help you decide which coil is right for you.
A common analogy for understanding Ohm’s Law is to imagine the plumbing in your home. The Voltage of your battery is the water pressure, the Amp of your battery is the water flow and the Ohm resistance is the width of the pipe
While all coils are designed to vapourise e-liquid, they can perform differently - this is on purpose. By using different types of wire and wick, you can effectively change how much vapour can be produced as well as enhance flavour and the lifespan of the coils. Coils are broadly split into two categories: sub ohm and mouth to lung.

What is MTL Coil What Are the Different kinds of Vape Coil?
MTL (Mouth To Lung) coils get their name from the style of vaping they support. Mouth to lung vaping describes the process of inhaling vapour into your mouth and then carrying it into your lungs, the same way you would smoke a cigarette. This style is especially popular amongst new vapers as it feels very familiar. In order to accommodate this style, mouth to lung coils have a high resistance (1.0 Ohm or higher) and will produce a small amount of vapour.
What Are Sub Ohm Coils?
Sub ohm coils, on the other hand, have been designed for creating large amounts of vapour. They get their name from their resistance, a sub ohm coil will always have a resistance less than 1.0 Ohm. This low resistance means they’ll accept a greater level of power and heat more e-liquid at a faster rate, this is why they produce larger amounts of vapour. They are also called DTL (Direct To Lung) coils because they allow you to adopt a direct to lung vaping style, wherein you inhale vapour straight into your lungs without holding it in your mouth first.
What Are Rebuildable Coils?
Rebuildable coils have been created for the purpose of being used with rebuildable atomisers. They require a far greater knowledge to use safely, including knowledge of Ohm’s Law, battery safety and general vape knowledge. Rebuildable coils are the pinnacle of customisability, as they allow you to pick an exact resistance and use metals of your choosing, including exotic metals such as Titanium and Nickel.
What E-Liquid Should I Use With My Coil?
The two main ingredients of e-liquid are VG (Vegetable Glycerin) and Propylene Glycol (PG), which are both widely found in food and medicine. The levels of VG and PG will always add up to 100%, for example, 70% VG / 30% PG or 50% VG / 50% PG. E-liquids with a higher PG percentage will be thinner, and will require less power to be heated into vapour. Whereas, e-liquids with a high VG percentage will be thicker, and consequently require more power in order to be vapourised.
PG basically bonds flavouring and nicotine to the e-liquid, therefore the more PG usually translated to increased flavour. VG, on the other hand, relates to how much cloud is produced, with higher VG consistencies producing larger amounts of vapour.
While preferred nicotine strength is often a personal choice, it’s important to remember that sub ohm coils will heat more e-liquid to produce more vapour. What this means is that you’ll also experience a greater nicotine hit.
Setting up your coil correctly the first time will guarantee a better experience. Some kits will come with a coil already fitted, if this is the case it’s recommended to take the time to check that the coil is securely fitted inside the tank.
If your coil arrives loose, check it’s in good condition. On your coil you may see small rubber rings, called O-rings, they act as a seal to ensure your tank doesn’t leak when it’s filled with e-liquid. Before installing your coil check that the O-rings are intact. These O-rings will also be found in your tank, again, check their condition before installation and use.
Insert the coil into the base of the tank and tighten it by hand, not too tight otherwise you won't be able to unscrew it, never use tools unless specified in the manual.
When Do I Need To Change My Coil
Coils will eventually need to be changed no matter how careful you’ve been. As a general rule, most manufacturers recommend changing the coil after a week of use. If you solely use a vape device this will be seven days, however if you don’t vape that often, you may find that changing your coils every two weeks is sufficient enough.

SUMMING UP
Coils are vital piece of vape hardware which can be daunting on first experience, but they are easy to pick and use when you know how. We hope this guide has helped give you some more confidence in relation to all things vape coil.
