I came across this short but great article that gave me a better understanding of sub ohm vaping. Sure there are charts and calculators online that you can use, but if you are like me, you would want a short, simple guide that deals less with numbers.
So here are a few things I got from this article that helped me get my head around this beautiful, yet sometimes confusing world of coil building.
1. “The lower the resistance, the bigger the clouds.”
False. While a low resistance build causes the wire to heat up faster and stronger, here’s a picture of 2 builds both clocking in at .8 ohms.
The build on the left will obviously produce more vapor. The difference between the two is the thickness of the wire. This is why sub-ohm vapers love to use thick wire (27 gauge and below) because it lets them use more wire while maintaining a low resistance.
2. “Thinner wire requires more wraps to cover more wick.”
Wrong, what will happen is the resistance will go up therefore your coil wraps will not heat up as quickly. To remedy this, use a smaller drill bit and do a dual coil build which come to the same resistance but with twice the coil.
3. “Dripping atomizers work best for sub ohm vaping.”
I can tell you based on personal experience that if you want to try extreme sub ohm vaping, use an RDA. Anything under .5 should be left for dripping atomizers or else you risk destroying your rebuildable tank. Below .5 builds get very hot. While RDA’s soak in the juice directly, tanks use the wick to seep in juice. If the heat is too strong, the wick in the tank will dry out quickly. Also, it might get too hot and just melt off the insulator in your tank.
