Your e-cigarette coil: a key part of your vaping experience

The coil is an essential component of your e-cigarette, responsible for producing vapour. It converts electrical energy from the battery into heat, allowing the e-liquid to be vaporised. In this article, we explain how e-cigarette coils work, how to replace them and how to optimise them to improve your vaping experience.

What is an e-cigarette coil?

The coil is a removable part located in the clearomiser or atomiser of your e-cigarette. Made from materials resistant to electric current, it converts electrical energy into thermal energy. This heat is used to vaporise the main components of e-liquid, propylene glycol and vegetable glycerine, to produce vapour.

The coil is the heart of your e-cigarette: without it, there is no vapour production and therefore no vaping. Depending on the model, it may be fitted inside the tank, either at the top or the bottom of the clearomiser.

How does an e-cigarette coil work?

The operating principle of an e-cigarette coil is quite simple. When you press the fire button, the battery sends an electric current to the coil, which converts it into heat. This heat warms the e-liquid in the tank and vaporises its main components.

The vapour produced then rises through the clearomiser chimney and is inhaled through the drip tip. It is important to note that coils are measured in ohms, a unit of electrical resistance. The ohm value affects vapour production and flavour rendering. A coil below 1 ohm, known as subohm, is ideal for direct lung inhalation (DL), while a coil above 1 ohm is more suitable for mouth-to-lung inhalation (MTL).
