A Sub-Ohm Tank is exactly what its name suggests. It’s a tank that uses less one ohm of electrical resistance. When using such a tank, you are more likely to create more vapor and denser clouds. The downside to these tanks is that they can be dangerous if you don’t know what you’re doing. If you use the wrong battery with a setup, the battery is likely to fail and then either start a fire or explode. This is obviously the worst possible scenario so don’t worry about it if you are using certified products to their respective capabilities. The best vapers know how to vape sub-ohm, so if you want to become a pro, you might want to give it a try. All you need is a powerful vape mod, a capable tank, and a good battery. Then you can show off those huge clouds to your friends and family!
