Vaping technology has evolved significantly over the years, offering options for all types of users—from those seeking a simple transition from smoking to experienced vapers exploring advanced techniques. Among these innovations, sub-ohm vaping has gained popularity for its ability to deliver intense flavours and large vapour clouds. But what exactly is sub-ohm vaping, and how do sub-ohm vape kits work?

In this comprehensive guide, we’ll break down the mechanics, advantages, and considerations of sub-ohm vape kits, catering to UK readers curious about this exciting vaping method.

What is Sub-Ohm Vaping?

At its core, sub-ohm vaping refers to using a vape device with a coil that has a resistance of less than 1 ohm. The term “sub-ohm” comes from the measurement of electrical resistance (ohms), which affects how electricity flows through the coil.

This lower resistance allows more electricity to pass through, generating higher temperatures and more vapour. Sub-ohm vaping is particularly popular among enthusiasts who enjoy direct-to-lung (DTL) inhalation, larger clouds, and intensified flavours.

The Key Components of a Sub-Ohm Vape Kit

To understand how sub-ohm vape kits work, it’s essential to explore their key components. These kits are specifically designed to handle the unique demands of sub-ohm vaping.

1. Sub-Ohm Coils

The defining feature of sub-ohm vaping is the coil. Sub-ohm coils have a resistance of less than 1 ohm, typically ranging from 0.1 to 0.9 ohms. These coils:

• Allow higher wattage and more heat.
• Vaporise e-liquid more efficiently.
• Require thicker e-liquids with higher VG (vegetable glycerin) content for optimal performance.

2. High-Wattage Mods

Sub-ohm vape kits often include high-wattage mods capable of powering low-resistance coils. These devices allow users to adjust the wattage and voltage, providing greater control over the vaping experience.

3. Large Airflow Systems

Sub-ohm vaping relies on increased airflow to cool the coil and produce larger vapour clouds. Sub-ohm kits feature adjustable airflow systems to fine-tune the balance between vapour production and flavour intensity.

4. High-Capacity Tanks

Sub-ohm vape kits often include larger tanks designed to hold more e-liquid. This is necessary because sub-ohm vaping consumes e-liquid at a faster rate than standard vaping.

5. High VG E-Liquids

Sub-ohm vaping works best with e-liquids that have a higher ratio of VG to PG (propylene glycol). VG produces thicker vapour clouds and smoother throat hits, making it ideal for the high temperatures of sub-ohm coils.

How Sub-Ohm Vape Kits Work

Sub-ohm vape kits operate by delivering more power to a low-resistance coil, resulting in higher heat and vapour production. Here’s a step-by-step breakdown of the process:

1. Power Flow

When you press the fire button on a sub-ohm mod, the device sends an electrical current to the coil. Because the coil has low resistance, it allows a higher current to flow through, generating more heat.

2. E-Liquid Vaporisation

The heat from the coil rapidly vaporises the e-liquid. Sub-ohm coils are designed to work with high VG e-liquids, which produce denser vapour and enhance flavour.

3. Airflow Regulation

The adjustable airflow system in sub-ohm tanks ensures sufficient cooling of the coil while allowing users to control the vapour’s density and temperature.

4. Direct-to-Lung Inhalation

Unlike mouth-to-lung (MTL) vaping, where vapour is drawn into the mouth before being inhaled into the lungs, sub-ohm vaping involves drawing the vapour directly into the lungs. This technique supports larger vapour clouds and a more immersive flavour experience.

Advantages of Sub-Ohm Vaping

Sub-ohm vaping offers several unique benefits that make it appealing to experienced vapers:

1. Intense Flavours

The increased heat and vapour production enhance the e-liquid’s flavour, allowing users to fully enjoy its complexities.

2. Massive Vapour Clouds

Sub-ohm vaping is ideal for those who enjoy producing large, dense clouds of vapour, making it a favourite for cloud chasers.

3. Smoother Throat Hit

The high VG content in sub-ohm e-liquids provides a smoother throat hit compared to the harsher sensation associated with high PG liquids.

4. Customisability

Sub-ohm vape kits offer adjustable settings, allowing users to tailor their vaping experience to their preferences, from cloud production to flavour intensity.

Who is Sub-Ohm Vaping For?

While sub-ohm vaping offers exciting possibilities, it’s not for everyone. Here’s who it’s best suited for:

• Experienced Vapers: Sub-ohm vaping involves advanced techniques and higher power settings, making it more suitable for those familiar with vaping.
• Cloud Chasers: If producing large vapour clouds is a priority, sub-ohm vaping is the way to go.
• Flavour Enthusiasts: Sub-ohm setups amplify flavours, appealing to those who want a richer taste experience.

Safety Considerations for Sub-Ohm Vaping

Sub-ohm vaping involves higher power levels, so it’s important to prioritise safety. Here are some key tips:

1. Battery Safety

• Use high-quality batteries designed for vaping.
• Ensure your battery’s amperage can handle the power demands of your sub-ohm coil.
• Avoid overcharging or exposing batteries to extreme heat.

2. Check Your Ohms

Always use a reliable ohm reader to ensure your coil’s resistance is compatible with your device and battery.

3. Use Regulated Mods

Regulated mods offer built-in safety features like short-circuit protection, making them safer for sub-ohm vaping compared to mechanical mods.

4. E-Liquid Compatibility

Only use high VG e-liquids to prevent coil burning and ensure optimal performance.

Choosing the Right Sub-Ohm Vape Kit

When selecting a sub-ohm vape kit, consider the following factors:

1. Power Range

Choose a device with a wattage range that suits your preferences. Beginners might prefer a kit with a lower power range, while experienced users might opt for higher wattage devices.

2. Tank Capacity

A larger tank is beneficial for sub-ohm vaping due to the higher e-liquid consumption.

3. Airflow Options

Look for a kit with adjustable airflow to customise your vaping experience.

4. Ease of Use

Some sub-ohm kits are more user-friendly than others. For beginners, a straightforward kit with clear instructions is ideal.

Is Sub-Ohm Vaping Right for You?

Sub-ohm vaping is an exciting way to elevate your vaping experience, but it’s important to assess whether it aligns with your needs. If you enjoy experimenting with flavours, creating massive clouds, and customising your vape settings, sub-ohm vaping could be a perfect fit.

For beginners or those transitioning from smoking, sub-ohm vaping may feel overwhelming at first. Starting with a simpler mouth-to-lung device might be a better option until you’re comfortable exploring advanced setups.

The Legal Landscape of Sub-Ohm Vaping in the UK

The UK’s vaping regulations, governed by the Tobacco and Related Products Regulations (TRPR), ensure that sub-ohm devices meet strict safety and quality standards. Key points to note include:

• Maximum Tank Size: Tanks are limited to 2ml capacity, though extension options are often available.
• Nicotine Strength: E-liquids with nicotine are capped at 20mg/ml, which is typically too strong for sub-ohm vaping. Most sub-ohm vapers use 0-6mg nicotine strengths.

Embracing Sub-Ohm Vaping

Sub-ohm vaping offers a unique way to explore the world of vaping, delivering unparalleled flavour and impressive vapour production. While it requires some technical knowledge and a willingness to experiment, the rewards are well worth it for those seeking a richer vaping experience.

Whether you’re a cloud chaser or a flavour enthusiast, sub-ohm vape kits open up a new realm of possibilities. With the right device, safety precautions, and high-quality e-liquid, you can unlock the full potential of sub-ohm vaping and take your vaping journey to the next level.
