The vaping world can be overwhelming when youre new to it. There are so many different products, juices, batteries, supplies, and the list goes on. In this guide for beginners well be talking about coils specifically for tanks and RDAs. So sit back, and read up on the interesting world of atomizer coils.
Sub Ohm Tank coils are a barrel like cylinder that are made from different kinds of wire such as Kanthal, Stainless Steel or Nickel. The majority of these coils have 100% Japanese cotton in bedded into the coil as well. Tank coils do have the tendency to burn quicker than any other coils, but well go over some tips that will help make your coils last longer.
How frequently you should change your coils depends how often you vape on your tank. In most cases, the lifespan of a sub ohm coil is about 1-2 weeks. If you are an avid vaper or a chain smoker, your coils will tend to burn quicker due to the constant usage of the tank. In these cases, we would recommend to change your coils every 3-5 days or until you start to notice a faint taste of burnt cotton. If you are an occasional vaper, your coils will last a little longer than 3-5 days. Typically, these coils will last you about 5-7 days. What matters is how frequently you vape and use your vape not how many days have passed since its last use.
For the most part, coils should be changed as soon as your coils start to give off a burnt taste. However, there are steps you can take to make your coils last slightly longer. One way to help your sub ohm coils is by vaping juices with lower VG. Several e-juices on the market now a days have a higher percentage of VG. Higher VG e-juices produce more vapor and huge clouds, but they also gunk up your coils. VG e-juices thick consistency creates gunk from all the excess juice that builds up into your coils. This causes your coils to lose their clean vaping taste and possibly not receive the flavor production you were looking for. Also, because the consistency of VG is so thick, the coils can not absorb all juice fast enough which is how the excess juice forms into gunk and thus giving you dry hits or a burnt taste.
For tanks users who want a longer lasting coil, trying looking into e-juices that are possibly higher in PG. PG is thin enough to be the ideal juice for vaping and does not build up junk.
Another tip is to always make sure to clean your coil. Once your tank is low after a big vaping session, remove the coil from the tank and blow any excess juice/gunk off the coil. Proceed to run the coil under warm water to completely remove all the gunk, then shake all the excess water and let the coil air dry for a while. Once the coil is completely dry, put it back in the tank, and fire it until the coil is heated. Let the coil cool down after it is heated, and then repeat that five times.
Cleaning your coils after a long vaping session will make your coil last longer, remove all excess juice, and produce a cleaner vape for your next session.
RDA or RDTA coils can be bought either premade or you can purchase the specific wire type you are wanting to work with and build the coils yourself. The most commonly used wires for these builds are Kanthal, Ni-chrome, Nickel, Titanium, and Stainless Steel. When you are done building your coils, you can use almost any kind of cotton but the preferred is still the 100% Japanese cotton. These types of coils are usually the most complex to build (depending on your desired build) but can be the easiest to take care of because they are openly exposed.
