The coil is one of the most important parts of an e-cig, their function is to heat the e-liquid in your tank and turn it into the vapour that you inhale. How does it do that?

  • The wicking material (the bit of cotton you can see inside the metal casing) absorbs the liquid in your tank when you fill up your clearomiser.
  • The wire in your coil (the little spiral of metal you can see inside the wicking material) is heated with power from the battery, which then starts to vaporise the liquid in your wick.
  • As you take a drag on the drip tip, the vapour travels up the chimney of your vape and into your mouth or lungs.
