Vaping - 101 Coils

This Article is the first in a series that we will be doing regularly to give you an easy to use reference for all of your hardware needs.  If there is a topic that you would like for us to cover feel to free to drop us a line.   All Vaping Hardware Explainedvapors deal with coils sooner or later. Coils have a huge influence on flavor, and not everyone knows how and when to change a coil. Unfortunately with the FDA regulations that have come into effect (check them out HERE ),  a number of us have had to rely on others to help them with this process or have come into the store asking for assistance and we have been unable to help due to the new regulations. Let’s take a look at what a coil is, and what it does. The coil is a crucial element to the atomizer, which heats e-juice to the point of vaporization. It is a spiral of conductive material that transforms electrical power (from your battery) into heat. No electricity, no heat. Coils can be made of Kanthal, stainless steel, ceramics, nickel, and various other conductors. If it vapes, it has a heating element of some variety. Knowing as much as you can about your coil empowers you as a vapor.   YOUR COILS LONGEVITY: Nothing lasts forever. Coils have a life-span, like all things. You may notice a “burnt” taste, less vapor production, or leakage issues with your atomizer. These are all signs that your coil may need to be changed. If your coil and wicking material looks dark, crusted, or flat-out ugly, change that coil! A lot of variables influence coil performance and longevity. Lower ohms means less resistance, which sucks more power from your battery to heat your coil faster. Heavier vaping means more demand from your coil. A casual vapor will have to change his or her coil less frequently than an all-day vapor. Flavors also influence coil longevity. Sweeter flavors caramelize and “gunk up” coils faster than, say, a basic fruit. If you love dessert or sugary sweets, anticipate more coil changes. Other variables include acidity, viscosity (higher VG blackens coils faster), and length of time the firing button is pressed (longer vapes = less coil life). HOW OFTEN SHOULD I CHANGE COILS? Some flavor purists insist on changing their coils and wicks every time they change flavor. Some vapors only change their coils when it is absolutely necessary. Think of it like changing the oil in your car; different performance needs changes the upkeep necessity. As a general rule, your coil should be changed if you experience any of the following:
  • Reduced flavor/vapor production
  • Leakage issues
  • Burnt taste
  • Lingering flavors
  • Dissatisfaction with your vape in general
Heavy vapors should change their coils every five to seven days. Moderate vapors should change their coils every two weeks. Light vapors can get away with changing their coils every three to four weeks. These are general guides, and if you experience any of the aforementioned symptoms, you should probably change your coil sooner.  


There is no universal method for coil changing. With such a wide variety of coil options in the vaping world, every atomizer has its own method options. Generally, you should ensure that you’ve emptied all e-juice from your atomizer. For tank users, make sure the tank is empty. For RDA folks, make sure excess e-juice is clear. For pre-built and stock coils, the coil can be unscrewed from the atomizer.  Build decks usually have a hex-screw or Allen wrench with which to unscrew your coil from the posts. No two atomizer models are identical, so some research may be required. Pre-build coils can be screwed into the atomizer deck. Remember: Righty-Tighty, Lefty-Loosey! Make sure the pre-built coil is tightly fastened and primed. Insert the coil to the post-holes, screw them in with the proper tools, and insure your ohms are registering in the proper range. Wick, prime, and apply e-juice as needed.  We understand that reading a wall of text and seeing it for yourself are completely different.  Our boy JRUE has your back with a video showing the entire process for changing out a RDA system Questions or comments? drop em below and be on the lookout for our next installment in Vaping 101
