Coils are essentially the part of your vape that heats up the E-Liquid and produces vapour. Coils come in a variety of materials including kanthal, stainless steel, nickel, and titanium. Coils also come in a variety of resistances which will affect the power output and how long the coil will last.
There are two main types of coils: pre-built coils and rebuildable coils. Pre-built coils are easier to use but have less customization options. Rebuildable coils allow for more customisation but require more knowledge to set up correctly.

No matter what type of coil you choose, it’s important to make sure that it is compatible with your device and that you replace it when necessary to ensure optimal performance.
