Vaping 101: A Beginner’s Guide to Sub Ohm Vaping


Welcome back to another instalment in our Vaping 101 series, designed to help new vapers get to grips with all things vaping, whether that’s choosing the right e-liquid strength or decoding vaping jargon.

In today’s post we’re tackling sub ohm vaping, something we get plenty of questions about from new vapers who have heard the term on blogs and social media but feel overwhelmed by the plethora of information out there about sub ohm vaping.

Sub ohm vaping is rooted in science and getting to grips with temperature controls, coils and airflow can be confusing for a seasoned vaper, let alone a newcomer. To take the mystery out of this cloud-tastic style of vaping, we’re going to run you through the basics so you can understand the process and make an educated decision about whether or not sub ohm vaping is for you.

What Is Sub Ohm Vaping?

Sub ohm vaping is a type of vaping that uses coils with a resistance lower than 1 ohm. This low resistance works in harmony with battery power and airflow to produce the huge clouds of vapour that are synonymous with sub ohm vaping.

So how does the low resistance lead to increased vapour production? The key to a lower resistance coil is using thicker wire. The thicker the wire, the larger the surface area of the coil, which means more e liquid can be vaporised and - bingo - you’ll see much larger clouds of vapour than you’re used to from standard resistance devices (which usually come in around the 2.5 ohm mark).

Why Sub Ohm?

Sub ohm vaping is one of the most complicated and expensive ways to vape, so why is it the favoured style of so many vapers? Let’s take a look at the pros and cons:


- Bigger clouds. This is the main pro you’ll see sub ohm vapers talking about. Whether you feel more satisfied with increased vapour production or you’re a cloud chaser who’s looking to join the growing community of competitive vapers, sub ohm vaping is the method for you if big clouds are what you’re after.

- Warmer vapour. Sub ohm vaping results in a high wattage being used, which creates warmer vapour. Remember, vapour should never be so hot that there’s any risk of burning your lips; if it does feel uncomfortably warm then seek expert advice).

- Enhanced flavour. We’ve put this one last on our list of pros as the jury’s out in regards to whether or not this is a legitimate benefit of sub ohm vaping. Some vapers report a more intense flavour when using a lower resistance but VG e liquid is recommend for sub ohm vaping, which is known for having a gentler flavour than PG liquids.


- Steep learning curve. In this post we’re only touching on the very basics of what sub ohm vaping is but there’s a lot of information to understand before attempting your first build or getting the most out of your first sub ohm device. We’re going to talk in more detail about the safety aspects of sub ohm vaping later on in this post, but this is an area where it’s particularly important to understand exactly what you’re doing and to seek professional guidance if you have any uncertainties.

- Increased e-liquid consumption. As you’d expect, sub ohm devices use far more e-liquid than their standard or high resistance counterparts.

- Increased battery power consumption. Similarly, when sub ohm vaping you’ll notice your battery drains a lot faster than usual. Be sure to keep a charger nearby!

A Note on Nicotine

One other thing to bear in mind before you try sub ohm vaping is that you’ll likely want to opt for a weaker e-liquid strength than you’re used to. When you sub ohm vape you’ll be taking in a lot more vapour than usual so, many vapers find their usual nicotine strength gives them too strong a hit.

Is Sub Ohm Vaping Safe?

The answer to whether sub ohm vaping is safe is an unhelpful yes and no. If you do your research, educate yourself fully and use a high quality device from a trusted vendor then you’re unlikely to run into any problems. With that said, sub ohm vaping does pose risks, which is why we urge any vapers thinking about trying it to do their homework and ensure they fully understand the process.

There’s a great thread here that delves into any safety risks associated with sub ohm vaping.

Sub Ohm Vaping with V2

Finally, can you try sub ohm vaping with V2? We’re delighted to tell you that you can! We offer the Trinity sub ohm vape devise with sub ohm capabilities. The Trinity has received the  best vape mod vote from top vape review sites.

The Trinity kit comes with a vaporiser, tank, standard atomiser (1.2 ohms), sub ohm atomiser (0.8 ohms) and a USB charging cord. There’s also a 0.5 ohm atomiser available, which can be purchased separately.


As we mentioned earlier in this post, there’s a lot to learn about sub ohm vaping and it would be impossible for us to fit it all into a single post, so today we’ve focused on helping you get to grips with the basics. We hope you found answers to any questions you have on sub ohm vaping but please don’t hesitate to get in touch with our team if you have other queries.
