One such technique that has gained significant attention among vaping enthusiasts is sub ohm vaping. In this guide, we will provide a short but trustworthy guide of sub ohm vaping, including its definition, different vaping styles, benefits, e-liquid compatibility, recommended sub ohm kits, modes available on sub ohm vape kits, and the pros and cons of sub ohm vaping.

This guide provides essential information on sub ohm vaping, offering a concise overview of its definition, vaping styles, benefits, compatible e-liquids, kit options, and operating modes. It helps readers make informed decisions about sub ohm vaping based on their preferences and needs. Suitable for beginners and experienced vapers, this guide serves as a valuable resource to navigate sub ohm vaping confidently.


Sub ohm vaping refers to the practice of using a vaping device that operates at a resistance below 1 ohm. This low-resistance setup allows for higher power output and increased vapor production. Sub ohm vaping is often associated with direct-to-lung (DTL) vaping, but it’s important to understand the distinction between the two.

A. Direct-To-Lung (DTL) Vaping

DTL vaping involves inhaling the vapor directly into the lungs without holding it in the mouth for an extended period. This technique allows for larger amounts of vapor to be inhaled, resulting in increased flavor and a more substantial throat hit. DTL vaping is commonly associated with sub ohm vaping due to the higher power output and airflow characteristics of sub ohm devices.

B. Mouth-To-Lung (MTL) Vaping

MTL vaping is similar to how one would smoke a cigarette. Vapor goes to mouth, then into lungs. This method provides a tighter draw, similar to the resistance experienced when smoking a cigarette, and is often preferred by individuals transitioning from smoking to vaping.


Sub ohm vaping offers several advantages over traditional vaping setups. Here are a few reasons why you might consider trying sub ohm vaping:

Increased Vapor Production

Sub ohm vaping allows for larger clouds of vapor to be produced, providing a more visually satisfying and immersive vaping experience. The combination of lower resistance coils and higher wattage output generates dense vapor clouds that can be impressive to behold.

Intensified Flavor

The higher power output in sub ohm vaping devices enhances the flavor production, allowing you to enjoy the intricate notes of your favorite e-liquids to their fullest. The increased heat and airflow help to extract the flavors more effectively, resulting in a more enjoyable and flavorful vaping experience.

Warmer Vapor

Sub ohm vaping tends to produce warmer vapor compared to higher resistance setups. This warmer vapor can be preferred by individuals seeking a more authentic and satisfying sensation, replicating the warmth and throat hit experienced when smoking traditional cigarettes.


Sub ohm devices often come with adjustable settings, allowing you to fine-tune your vaping experience to your preferences. With options to adjust wattage, airflow, and coil resistance, you have greater control over the intensity of your vape. This customizability allows you to find the sweet spot that delivers the perfect balance of flavor, vapor production, and throat hit.

Versatility with E-liquids

Sub ohm vaping works well with high-VG e-liquids, known for smoothness and clouds. They create dense vapor thanks to their thick consistency. Sub ohm devices are also good for high-nicotine e-liquids, delivering nicotine smoothly at higher concentrations.


When it comes to choosing e-liquids for sub ohm vaping, there are a few factors to consider. Sub ohm devices are designed to handle high-VG e-liquids, typically with a VG/PG (propylene glycol) ratio of 70/30 or higher. High-VG e-liquids are known for their thicker consistency, which allows for increased vapor production and a smoother vaping experience.

It’s important to note that using high-VG e-liquids may require more frequent coil changes due to the liquid’s viscosity, which can cause faster coil buildup. Additionally, some e-liquids may have higher nicotine concentrations, so it’s crucial to choose an e-liquid with an appropriate nicotine level that suits your preferences and nicotine requirements.


Choosing the right sub ohm kit depends on your personal preferences, vaping style, and experience level. Here are three common types of sub ohm kits to consider:

A. Sub Ohm Vape Pen

Sub ohm vape pens are compact and user-friendly devices, making them an excellent choice for beginners or those who prefer a more portable setup. These devices often feature built-in batteries, simple operation, and a selection of compatible sub ohm tanks. Vape pens offer a convenient and hassle-free sub ohm vaping experience, requiring minimal setup and maintenance.

B. Sub Ohm Pod Kits

Sub ohm pod kits combine the convenience of pod systems with the enhanced performance of sub ohm vaping. These devices use replaceable pods or cartridges with built-in coils, making them easy to use and maintain. Sub ohm pod kits are a great option for vapers who want a compact, versatile device without the need for complex settings. They provide a balance between portability and performance, making them suitable for both beginners and experienced vapers.

C. Sub Ohm Box Mod Kits

Sub ohm box mod kits are more advanced devices that offer a wide range of customization options. They typically feature removable batteries, adjustable wattage, temperature control, and various safety features. Box mod kits are ideal for experienced vapers who enjoy tinkering with settings and optimizing their vaping experience. These kits provide maximum power output, extensive battery life, and the ability to use a wide variety of tanks and atomizers, giving you complete control over your vaping experience.

Consider your vaping preferences, lifestyle, and budget when selecting a sub ohm kit to ensure it aligns with your needs and expectations.


Sub ohm vape kits often come with various modes and settings to enhance your vaping experience. Here are a few common modes you might encounter:

A. Variable Wattage Mode

Variable Wattage (VW) mode allows you to adjust the power output of your device. By increasing or decreasing the wattage, you can control the heat produced by the coil, which directly affects the vapor production and flavor intensity. VW mode gives you the flexibility to fine-tune your vaping experience to match your preferences and the specific e-liquid you’re using.

B. Temperature Control Mode

Temperature Control (TC) mode enables you to set a specific temperature at which your coil will operate. This mode is compatible with specific coil materials, such as stainless steel, nickel, or titanium, and helps prevent dry hits and coil damage by regulating the temperature of the coil. TC mode provides a consistent vaping experience, eliminating the risk of burnt hits due to overheating.

C. Bypass Mode

Bypass mode essentially turns your device into a mechanical mod by bypassing the regulated circuitry. In this mode, the device provides direct power from the battery to the coil, allowing for a more immediate power delivery. Bypass mode is recommended for advanced users who have a good understanding of Ohm’s Law and battery safety. It provides a raw and unregulated vaping experience, similar to using a mechanical mod.

D. Variable Power Curve

Some advanced sub ohm devices offer a Variable Power Curve (VPC) mode, allowing you to customize the wattage output over a specific time interval. This mode can be useful for achieving a tailored vaping experience, especially if you prefer a gradual ramp-up or different wattage levels throughout your vape. VPC mode offers advanced customization options for vapers who enjoy experimenting with different power settings.


As with any vaping style, sub ohm vaping has its advantages and disadvantages. Let’s explore the pros and cons:
