What are vape coils

Vape coils are the heating element in a vape device. When power is applied, the coil heats up, turning e-liquid into vapour.

Coils are typically divided into two types: MTL (Mouth-to-Lung) and DL (Direct-Lung):

  • MTL coils: Higher resistance, smaller ports, thinner e-liquid (higher PG), lower wattage
  • DL coils: Lower resistance, larger ports, thicker e-liquid (higher VG), higher wattage

Modern coils, with their push-pull installation designs, are quick and easy to change and offer great cost savings over fixed-coil pods. For more information, see the guides and FAQs below.

Choosing the right coil for your device

It’s vital to use the right coil for your device. This is usually listed on the product packaging. You can also find a list of compatible coils on our device pages, and compatible devices on our coils page. If in doubt, pop our customer service team a message!

FAQs

How do vape coils work?

E-liquid is absorbed through holes called ports in the coil housing. The e-liquid soaks into the wicking material. When powered, the wire inside heats up. This in turn heats the e-liquid in the wicking material, turning it into vapour when inhaled.

Modern coils usually come with a push-pull design that makes installing or replacing the coil in your tank or pod very quick and easy.
What are ohms?

You’ll notice when shopping that you’ll often have a choice of coils with different ohms.

Ohms are actually a measure of resistance. More ohms mean the coil has more resistance, and lower ohms means the coil has less resistance. Below shows some of the differences between higher and lower resistance coils.

Low resistance

  • More clouds / power needed / airiness
  • Shorter coil life / battery life
  • DL (Direct-Lung) vape style

High resistance

  • Less clouds / power needed / airiness
  • Longer coil life / battery life
  • MTL (Mouth-to-Lung) vape style
How long does a coil last?

Coils for most pod systems and starter kits usually last around two weeks. However, coils for more powerful devices may only last a few days, as they are typically used at higher wattages.
How long does it take to replace a coil?

With modern devices, the process takes seconds. Simply pull the old coil out of your tank and push in a new one. However, some older coils may need to be screwed in, which may take slightly longer.
Why does my coil taste burnt when it’s new?

This is usually caused by not priming the coil or using too high a wattage level. See our guide to preventing coils from burning for more information.
