Whether you have an e-cigarette, a pod mod, a refillable pod or even a box mod, the core elements are the same. Composed of three main components, e-cigarettes and vape devices contain a rechargeable or replaceable battery, a vaporizer and an e-liquid reservoir.
At the very heart of each device is the atomizer. Typically consisting of three parts – the main body, the coil and the wicking material – an atomizer is a small yet mighty component that converts energy from the battery to heat the coil and vaporise e-liquid.
The resistance of a coil is measured in ohms and the required ohm level greatly depends on the device type, e-liquid formulation type and the preferred amount of vapour production.
Coils with a lower resistance (typically less than 1.0ohm) typically heat up more to produce larger clouds for what is commonly referred to within the vaping community as a sub ohm or cloud chasing vape. Coils with a higher resistance (typically more than 1.0ohm), on the other hand, are slightly cooler and produce a more subtle vapour that is most similar to smoking a traditional cigarette.
As a rule, box mods should be paired with low resistance coils at higher wattages for impressive vapour production; pen-style devices used with 50:50s or Nic Salts at a lower wattage for a vaping style that is most like smoking; and pod mods and refillable pods with most liquids depending on preferred vaping style and the device wattage output.
There are various coil types available to choose from: Kanthal, Ceramic, NiChrome, Stainless Steel, Nickel and Titanium. The most popular of these coils is Kanthal – combining iron, chromium and aluminium, Kanthal coils can withstand seriously high temperatures and has a quick heating time to produce thick, dense clouds of vapour. Ceramic coils are also well-loved due to the improved airflow that allows for great flavour and a smooth draw.
Coils should be changed regularly to ensure a great tasting vape every time, although the length of time a coil may last depends on vaping style and e-liquid preference. As high VG e-liquids – think Dinner Lady 30:70s and Shortfills – tend to be thicker and sweeter, the accompanying coil can burn out quicker than with other e-liquid formulations. Vapers will know when their coils should be replaced when noticing a distinct burnt or unpleasant taste to their vape.
Depending on the device type you have, changing a coil is relatively straight forward and simple to do. With many pod devices, coils tend to be built into the replacement pods – vapers can simply remove the old pod and replace with a new one. With other devices, changing a coil is less simple but, for the most part, still very simple due to advanced “plug and play” attachments that allow vapers to insert their coil and vape.
