Rebuildable Dripping Vaping Atomizer, close up

If you’re new to vaping, here are a few tips. Thoroughly learn the key points of sub-ohm vaping. If you’ve just quit smoking cigarettes or you’re just vaping for fun, you’re at the right place. First off, sub-ohm vaping produces large amounts of vapor and definitely a stronger nicotine hit. Ejuice flavors are also enhanced. If that’s what you’re looking for, this is your ohm page!  

Want to live a little dangerously? Try a 28-gauge dual-coil .3 ohms. Sub-ohms can produce a lot of vapor because of heating up faster and get much hotter, and more vapor creates a stronger nicotine hit. Resistance is not the only thing that’s critical though. And you need to understand why it is so important.

Comparing different builds, for instance, a 26-gauge wire and a 28-guage wire both have the resistance of .8 ohms, but the thicker 26-gauge requires more wire to get .8 ohms. It will produce more vapor because there is more surface area to vaporize the ejuice. Now what happens when you try to get .8 ohms using a 32-gauge wire? The wire is too short and that that’s not practical. Thin wires are used for the higher ohm builds. For a sub-ohm, it’s best to use a thicker, 28-gauge wire. For this article, we will talk mostly about 28-gauge builds.

There are also dual-coil builds. Both use 28-gauge wires and both have the resistance of .8 ohms, but the dual-coil requires 4 times more wire to get .8 ohms. This is much more wire and will produce a lot more vapor. That’s why sub-ohm vapers prefer to use a minimum of 2 coils.

Straight out of the box, the air holes are small. Vapers drill larger holes and the coils get really hot so this also helps with the heat. Now, with the larger holes, the vapor is diluted and draws more air. The key to controlling vapor is resistance, wire surface area, and airflow.

Very low resistance works best with a dripper. With some atomizers, the ejuice will vaporize faster than the wick can absorb it. Drippers don’t have this problem because the ejuice drips directly onto the coil. Note: The heat from sub-ohm will eventually wear out the insulator, the part that separates the positive from ground. When damaged, it can create a short. Don’t worry - this part is replaceable.

The most important thing to keep in mind is the resistance limit. This is different for every battery. Case in point, if you have an AW 18650 2000 mA power battery, the lowest vape ohm to run would be .3 ohms. If you go too low, you will short out the battery, and that can cause the battery to explode.
