The Importance of The Choices of Coils

The Importance of The Choices of Coils.In general, vertical coils should last longer than horizontal coils because the more airflow keeps them cooler. However, dual coil designs share the work-load between two coils, meaning a dual coil design will last longer than a single vertical coil design. Wicking material can differ between cotton (organic, and unbleached), silica and mesh, but in stock coils the most widely used is cotton.

Cotton is a very good all rounder in regards to:

lifespan
flavour
vapour production
the amount of liquid it can hold
ease of use
Silica is used in more ‘old fashioned’ tanks (such as our H2 model) and previous CE incarnations, and is sometimes used by vaping enthusiasts as a preference.

Mesh is almost exclusively used in ‘Genesis’ tanks (so called after the original bottom tank/top coil design), and occasionally in RDAs. If building coils yourself, it is important to get the amount of wick just right. The general rule of thumb with wick passed through the coil, is to have a slight pull as you adjust the cotton back and forth, but no real resistance. This leaves room for it to be soaked with liquid (expanding as it does so), without becoming so tight that the liquid cannot flow at a decent rate.

As a general rule, the higher the resistance, the less wattage you need for your tank to perform. The lower resistance the more power you need, and the more vapour it will produce, though there are exceptions. Higher resistance coils, generally in the 1-2 Ohm region, are primarily used for mouth to lung style vaping. These are best run (again this is a general rule, devices and coils vary in performance) within the 7-20w range.

These types of coils tend to heat slightly slower, are better suited to higher nicotine levels than sub ohm coils, and are best for those seeking more of a smoking like experience. Sub ohm coils, those below 1 Ohm of resistance, are more suited to those who prefer a full on vape, an instant rush of masses of vapor. The lower the resistance, the faster it vapourises liquid, due to a combination of surface area and the speed in which it heats, and the more powerful and safe a battery you will need. Ni200 coils have what in wattage mode would be an extremely low resistance, something which could be potentially dangerous due to stress on the battery cell.

Please note that there are risks when you start coil building and modding. We take no responsibility for any issues that arise should you start coil building. This section should be taken purely as an introduction, and there are links to more detailed guides for those interested. Before embarking upon building your own coils there is one major thing to remember!

Check the resistance of any coil before firing it, using either a dedicated ohm meter, or a regulated device that will show your resistance.

There are two reasons for doing this.
Ensuring that the resistance is within your devices limits.
Ensuring that the coil doesn’t short, which can lead to serious battery failure and injury.

When building your own coils, it is important to consider exactly what type of vape you desire, and to tailor your build to suit.The space you have to work with, and the number of coils you are able/wish to use, can help determine what wire is best. If you prefer a 0.5 Ohm build and have both a restricted decked single coil device, and a dual coil larger deck, then a different type of build is required. A dual coil build halves the resistance. So to achieve the same result, you would need to double the resistance in each individual coil of the pair.
