A complete guide to sub-ohm vaping

As you enter the world of vaping, you will come across a slew of vaping lingo that is not immediately clear. One of the phrases you will most likely encounter and see used quite often is “sub-ohm and sub-ohm vaping”. It’s a phrase you’ve most probably happened across already. But what does it mean exactly, and why is sub-ohm vaping such an important term in vaping?


By definition, sub-ohm vaping refers to vaping with an e-cig device that makes use of vape coils with a resistance of less than one ohm – that is, 1.0 Ω and below (aka below ohm). Most regular vape devices have a resistance range of 1.5 to 3 ohms, which is “above ohm”. When the coil resistance exceeds 1.0 ohm like with these said devices, it is said to be on the higher side. This is why you’ll also find regular vaporizers and their coils being labeled high-resistance devices/coils.

Sub-ohm vaping, for their part, include low-resistance devices as their below-ohm coils offer reduced resistance when an electrical current is applied. This is in fact where the term ‘sub ohm’ comes from.

Lower resistance is obtained by employing thicker wires, thanks to a large surface area which allows for more room for current to flow.

Sub-ohm devices are often paired with thicker juices that are high in VG e-liquids content. These high VG e-liquids are simply known as sub-ohm e-liquids or sub-ohm tanks. These sub-ohm tanks are only compatible with low-resistance tanks or devices.

What are the main advantages of Sub-ohm vaping? Why should you prefer it?

We have a few answers to your question.

There are a couple of notable benefits to sub-ohm vaping that makes it such an attraction for many vapers.

-        Larger clouds

In sub-ohm vaping, the first benefit has to do with the high quantities of vapors produced by this type of vaping. If a large number of clouds appeal to you, you will love sub-ohm vaping


-        Smooth 

Sub-ohm vaping also promises a smooth vape experience, which is a result of several factors, most probably the reliance on high VG e-liquids, as well as low-nicotine juices.

Yes, sub-ohm juices are typically low in nicotine content due to the high-powered 18650 batteries, sub-ohm coils nature of these devices would result in a harsh throat hit where the nicotine content to be anything above 6mg/ml, which tends to be the nicotine ceiling for sub-ohm juices. For the most part.

-        Rich in flavor

The third benefit has to do with the sub-ohm vaping flavor 

While high VG e-liquids, which make a larger portion of sub-ohm juices, may not be a good carrier of flavor like PG, the fact that you are inhaling large quantities of vapor (warmer vapor for that matter) at any one time means the flavors tend to be more intense.

Sub-ohm coils can vaporize lots of juice at a go, so every single draw comes bursting and full of flavor.

Apart from these advantages, a few other factors might affect your sub-ohm vaping experience

A few of those are listed below

-        Wattage

This is the actual power being produced. The higher the wattage, the more heat the device produces. In turn, the more the vapor and the more intense the flavor.

In other words, bumping up your wattage level will produce more heat, which will consequently result in more clouds and more flavor.

On the downside, high-wattage vaping is costly as you will use up your e-liquid more quickly.

-        Coil resistance

Another determining factor in sub-ohm vaping. Coils that boast a large surface area conduct more current as a result of their low resistance.

Since wattage output and resistance are inversely proportional, the effect will be the opposite in the case of thinner coils as compared to sub-ohm coils

-        Battery voltage

Voltage is the power being generated by your vape battery.

The higher the voltage the battery generates, the higher the wattage – bar instances when resistance is also increased. The most popular battery in sub-ohm vaping is a 18650 battery. You should also always know that when to change the 18650 battery.


Truth be told, sub-ohm vaping is a bag of chips. It promises loads of fun what with the immense clouds and the high VG e-liquids.

But its advantages stretch beyond what we have cited here.

For example, an aspect we love about sub ohm high VG e-liquids is that they also come in zero-nicotine variants. This could be either in the standard 10ml sub-ohm bottles or as shortfills. Read more about short fill e-liquids here.
