In this tutorial, I show you how to build a simple dual coil setup for the Griffin RTA by Geekvape, how to wick it and how to fill up your tank.This is one of my first build videos ever, so things a bit all over the place. I never realized how disorienting it can be keeping on eye on what you’re working with, and the other on your camera to make sure everything is being recorded.Some people have commented that the wicking technique show here is wrong, but it has always worked for me, with the type of ejuice I use and how I vape.So if it doesn’t work for you, consider using less cotton and instead of stuffing the cotton down all the way, just get enough in to stuff the juice channel openings at the deck.You may also want to watch my review of the Geekvape Griffin RTA for more information on how it works, if you don’t already own it.
