Vape coil, or atomizer as it is usually known as, is a device that vaporizes the e-liquid. At its core, a vape coil is just a heating element that heats up the e-liquid and creates a mist out of it. A vape coil with higher resistance requires less power to vaporize the same amount of e-liquid. The resistance of vape coils is measured in ohms.

Vape coils are made of a variety of materials of high resistive power, such as nickel, stainless steel, titanium, kanthal, and others. Quite often, the term atomizer is used to refer not only the vapecoil, but also the device containing the vape coil. There are mainly two categories of atomizers and a variety of designs featured in each of them. Let’s take a glance at them.

Vape coils and what they are 



Pre-made Vape Coils

These are the simplest type of vape coils. They do not require any effort to make and can be used right away with a vape mod. However, they are not versatile. Pre-made vape coils are designed for specific types of mods. Some mods can be fitted with a variety of vape coils, and their compatibility is usually mentioned in the manual supplied with those mods Each coil comes with a fixed resistance. If you like to vape at low-wattage, then you need a higher resistance vape coil. Although the lower resistance coils require more power, they produce a lot more vapor.

The best thing about premade vape coils is that they are very easy to use, and deliver consistent results. They come with less initial investment, but cost more in the long run as they usually last only a week and cannot be re-wicked. So, you are left purchasing one of these every few days.

Rebuildable Vape Coils

Rebuildable vape coils offer the best vaping experience. However, it’s not easy to make one, and beginners are not recommended to try them.

Users get to create coils that are tailored to their specific requirements, and replace the wicker as many times as they want and reuse the atomizer. Although the initial costs are higher, the long-term usage costs are way lower. There are multiple types of rebuildable vape coils, and here’s a brief look into them.


RDAs are the easiest rebuildable vape coils to make. These atomizers make use of a simple vape coil off of which e-liquids are vaporized to produce copious amounts of vapour. They produce intense flavours too.


Rebuildable tank atomizers make use of a pressurized tank system to supply the e-liquids to the coil. The coil has to be built by the users according to their vapour needs.


A lot of acronyms like GTA, RDTA, etc. get thrown around in the market these days. But, they are all just RDAs and RTAs with slight variations. There is no major difference in their operation. They all make use of rebuildable vape coils. All of these rebuildable vape coils take a considerable amount of time to make, and only experienced vapers can get best results out of them. However, once their construction is mastered, they work fantastically. They produce great quantities of vapour and excellent blasts of flavours. They can be customized to the user’s preference. However, they are difficult to maintain and time consuming to make.
