Priming coil heads is an important technique to ensure you have the best vaping experience possible. It can be accomplished in two easy steps — but if forgotten, can be a costly mistake. Today we’ll discuss the simple priming process, and help you avoid the unnecessary burning of cotton!

Wetting The Wick


This can be accomplished in one of two ways:

  1. Dripping a few drops of eliquid on top of your coil will ensure the cotton wrapped around the metal heating element is wet before it is installed.
  2. Dripping e-juice around the openings of your coil (the little slots) where the white cotton is partially exposed, with the wet cotton wrapped around the heating element as well.

NOTE: You only need 4-6 drop of e-juice to prime your coil head. Ideally, you’d like to see the cotton change colors from opaque white, to a dull colored white; this is the color transition wicking material makes when it has been absorbed with e-juice.


After pre-soaking your coil head with e-juice (priming step one), you can proceed to install the coil in your sub-ohm tank following the required steps provided by the manufacturer, and fill your tank with the desired amount of e-liquid. If you’re really picky like me, I fill my tanks 3/4 – 7/8th of the way every time; no sense in overfilling!



After wetting your coil head directly with e-juice, you may be tempted to throw it on your mod and start vaping immediately. But trust me when I say, “let it sit”. Allowing the e-juice to fully saturate your wicking material while inside your sub-ohm tank will ensure a smooth vaping experience.

TIP: I normally let my tank sit for 3-5 minutes before vaping. You could probably get away with 1-2 minutes. But I find that getting up to do something (grab a drink, a beer whatever), and then coming back to the tank, helps you get in a routine of letting the coil soak long enough.

This thicker the e-juice, the longer I will let my tank sit before vaping. With a 50% VG blend, you don’t have to worry too much, but with an 80% VG blend, you’d be best served by letting that tank sit an extra minute or so.  

First Vape

This first vape isn’t really a step in the priming process. And if you follow the first two steps correctly, you shouldn’t have to worry about this at all.

Regardless, before I take the first vape from my tank, I always pulse the coil head a few times (by simply pressing the fire button quickly…). Performing this quick little “pre-vape” step allows a bit of air to be sucked into the coil head, completely soaking the innermost pieces of wicking material.


Priming your coil head is simple. The same two-step priming process can be used with any coil (even the older clearomizer gigs) utilizing any kind of wicking material (cotton, fiber, etc…), and any sub-ohm tank. For larger capacity tanks, I recommend at least a five minute sitting time. Doing this will ensure a burnt-free vape from the start, and help your coil heads last longer (with proper cleaning as well), saving you money in the long run!
