There are many different types of coils to choose from, the reason for this is some users prefer a high wattage coil with high airflow and some users prefer a low wattage coil with less air flow. The higher the wattage the coil is rated for the more power is required also meaning more E-Liquid consumption.
This is something the user needs to take into strong consideration. Putting aside PG & VG ratios in E-Liquids. Heat and power effects how much nicotine the user receives.
- A coil that is rated at a lower ohm (eg 0.15ohm) will require much more power (possibly 100+ watts depending on the manufacturer of the coil) in order for the coil to heat up and produce vapour. In respect the more power required will translate into more vapour production, more vapour production means more nicotine delivery. A user may only require 1mg of nicotine if vaping on a low ohmage coil in order to stop the “cigge” cravings. The more power means more E-Liquid consumption.
- A coil that is rated at a higher ohm (eg 1.50ohms) will require much less power (between 5-10 watts depending on the manufacturer of the coil) in order for the coil to heat up and produce vapour. Because there is less vapour production being produced the user will receive less nicotine delivery compared to a lower ohmage coil that produces more vapour. In this instance the user may require 9mg of nicotine delivery in order to stop the “cigge” cravings. The less power means less E-Liquid consumption.
Sub-Ohm tanks have become very popular because of their options available, ease of use, E-Liquid capacity and reliability. The user can choose coils ranging from 0.15ohms all the way up to 0.95ohms depending on the manufacturer of the tanks and coils. This allows the user to choose from a very large range of tanks and coils that may suit the user best without the need to go into “rebuildable atomizers” or a basic stick style “vape pen/starter pen style kit”.
If no Sub-Ohm tank suits the user, they have an option to choose and vape with a “rebuildable atomizer” (RDA or RTA), the user can build the coils to the specs that they desire. Though much research must be done by the user before even attempting to use a rebuildable atomizer as these types of hardware are for advanced users only.
