What Is a Vape Coil?
A vape coil is the tiny yet powerful coil heating element that is found inside every e-cigarette or pod kit. It’s made of metal wire and is wrapped around a wick and cotton in coil form. It also has a cotton (or wick) inside it, which absorbs the e-liquid. And when you press the fire button, it heats up and turns e-liquid into a flavourful vapour.
So, what really is the role of the coil in vaporising e-liquid? The main role of the coil is to provide a perfect heat level to produce vapour without combustion. Know that your flavour intensity, vapour output, and even battery use depend on how good the coil performs.
How Vape Coils Work (Step-by-Step Guide)
Here’s a simple breakdown of vaping coils working:
Electricity Heats the Coil
When you turn your vape on, the electricity travels from the battery to the coil heating element. The metal wire offers coil resistance (measured in ohms). It then converts that electrical energy into heat.Wick and E-liquid Absorption
There is a wick and cotton inside the coil that acts like a sponge. The cotton draws in e-liquid through the tank’s capillary system, keeping the coil saturated and ready for vaporisation.Vapour Production
Once the coil heats up, the absorbed e-liquid is converted into vapour, forming tiny droplets that create a cloud of vapour. This process defines coil performance and vapour production. A higher wattage and lower resistance create more vapour. However, lower wattage setups offer cooler and more flavourful hits.Comparison to Cigarette Combustion
When compared to cigarettes that burn tobacco, vaping uses controlled heating. This produces very few harmful chemicals and zero smoke. The coil’s even heat distribution, especially in mesh coils, delivers consistent flavour without combustion.
