What is Sub-Ohm Vaping?

Sub-ohm vaping describes the practice of using an e-cigarette containing a coil with a resistance below 1 ohm. To put this in perspective, with regular vaping the coil resistance is usually somewhere between 1.5 to 3 ohms. 


Why Do People Sub-Ohm Vape? 

When a coil has less resistance, the coil heats up faster. This means that more e-liquid is vapourised which causes more flavour and thicker clouds. Many people prefer this method of vaping because the enhanced flavour will, of course, create a more enjoyable and powerful vaping experience. Many people also love creating large clouds - whether this is for personal enjoyment or for practising vape tricks. These people are often referred to as cloud chasers


How You Can Enhance Your Sub-Ohm Vaping Experience

When sub-ohm vaping, it’s important to understand how other factors will affect your experience. Namely, the coils you use, the wattage of your device, and the voltage of your battery.

Firstly, coils with a larger surface area will conduct more electrical current because of lower resistance, and thinner coils will do the opposite. This means that wider coils will increase the effects of sub-ohm vaping. 

Secondly, if you choose a higher wattage on your e-cigarette decide, this will also create more heat and therefore increase the sub-ohm experience. You will experience the increased flavour and thicker clouds to a further extent. 

Lastly, a higher voltage battery will also increase the sub-ohm vaping effects. This is because a higher battery voltage causes a higher wattage. However, if your vape coil has a higher resistance (so you aren’t sub-ohm vaping), this won’t be the case. 


Are There Any Risks to Sub-Ohm Vaping?

If you use good quality, professionally manufactured coils and vaping equipment, sub-ohm vaping is safe. 

Sometimes vapers will try to build their own coils or vape mods without fully understanding the process or how sub-ohm vaping really works. This can lead to them damaging their equipment and even injuring themselves. It’s important to remember that electricity is the main component in e-cigarettes and coils, so you should not be attempting to build your own equipment if you don’t fully understand the risks involved. 

Before sub-ohm vaping, you should also ensure that you understand how wattage, resistance, and voltage work together (which we explained briefly above). Once you understand this, you’ll be able to understand the best combinations and how to stay safe. 

Lastly, you should ensure that you don’t overheat the vape battery when sub-ohm vaping as this can be a strong culprit for safety hazards.
