Sub-Ohm Vaping Tips
Sub-Ohm has the potential produce a lot of vapor. The wires heat faster and gets hotter. More vapor equals a stronger nicotine hit, but the resistance is not the only thing that’s crucial. We’ll look at some builds to understand why.
The build on the left is using a 26 AWG wire and the one on the right is a 28 AWG wire, which both has the resistance of 0.8 Ohms. But as you can see, the thicker 26 AWG requires more wire to get 0.8 Ohms, which means it will produce more vapor. That’s because there is more surface area to vaporize the e-juice. So what happens if we try to get 0.8 Ohms using a 32 AWG wire? The wire will be so short to the point that it’s not practical. Thin wires are used for the higher ohm builds. But for Sub-Ohm, it’s best to use a 28 AWG or thicker wire.
Now let’s look at a dual coil build. Both are using 28 AWG wires and both have the resistance of 0.8 Ohms. But the dual coil requires four times more wire to get 0.8 ohms. That’s why sub-ohm vapers like to use at least two coils.
The coils get really hot, so airholes will help with the heat as well. Though will larger holes, the flavors tend to get diluted because it draws more air. So the keys to getting more vapor are resistance, surface area and airflow.
Extremely low resistances work best with a dripper. With the other atomizers, the e-juice will vaporize faster than the wick can absorb. Drippers don’t have this problem because you drip e-juice onto the coil.
The heat from sub-ohm will eventually wear out the insulator, the part that separates the positive and ground. If this is damaged, it can create a short. Not to worry though, this part is irreplaceable.
The most important thing to keep in mind is the resistance limit. It’s different for every battery and this is a great chart that you can reference.
