All e-cigarettes function because of their coils. Vape coils are a key element of any kit, from vape pen to box mod, ensuring that the e-liquid can get to temperature and vapour can be produced. There are a range of different kinds of coils on the market and sometimes it can be hard to know exactly what you need to perfect your vape. Scroll to the bottom of the page for more information about coils and how to choose the right ones.
Understanding Vape Coils
Vape coils are a replaceable element of most e-cig kits. The unit which heats up the e-liquid and turns it into vapour is known as the atomiser or coil. It simply refers to a coil of wire which is wrapped in wicking material which is able to soak up the e-liquid and draw it up into and through the coil. When the e-cig is turned on the power from the battery heats the coil and the e-liquid is vaporised.
Atomiser heads feature an outer casing, the wire, in the form of the coil, and the wicking material which is often cotton. The way the wire is wrapped around the wicking material creates the coils. Coils are available in different metal types and also in different resistance levels.
What are Ohms and Why do they Matter?
Most vape coils have an ohm rating between 0.5 and 2.0. Worded simply, the 'ohm' or 'resistance' rating is a measure of how much heat the coil can conduct, where lower ratings mean more heat. Typically the vape kit you opt for will have a set of compatible coils, so you needn't worry too much about resistance ratings. 50/50 e-liquids work well with almost all coils, so if you're unsure on compatibility, this is a great place to start.
When buying coils, you may see them referred to as sub ohm. This means their resistance level is 1 ohm or below. There are significant differences between the resistances and they create an entirely different vape experience.
Lower ohm coils offer a warmer vapour and larger amounts of vapour. E-liquids are used up more quickly with lower ohm vape coils but this is due to more vapour and a more intense flavour.
Higher ohm vape coils use less e-liquid and provide a cooler, less intense vaping experience. It is also recommended you choose the right kind of e-liquid for your chosen e cig coil resistance. Lower ohm coils are best enjoyed with liquids which have a high vegetable glycerin (VG) formula whereas higher ohm coils work best with high PG (propylene glycol) formulas.
How often should I replace my coils?
E cig coils are designed to be replaced and the number of variables involved in their design will affect how long they last. Guidelines about replacement are very general and it is something you should feel as you vape rather than look for exact timescales for.
Heavy vapers, who vape continuously throughout the day, may need to replace their vape coils every five to seven days. Vapers who vape consistently but only take one to two drags each time may find their e cig coils last 14 days. Light vapers who take a few hits here or there but are never consistently attached to their e cig may see their coils lasting as long as three weeks or even more.
