Sub-Ohm Vaping: What it is and how to do it

Sub-ohm vaping has gained popularity among vaping enthusiasts for its ability to produce dense vapor clouds and intense flavor experiences. However, it’s essential to understand the principles behind sub-ohm vaping and how to do it safely and effectively. In this guide, we’ll explore what sub-ohm vaping is, the benefits and considerations, and how to get started with sub-ohm vaping.

What is Sub-Ohm Vaping?

Sub-ohm vaping refers to using vaping devices with coils that have a resistance of less than one ohm. Traditional vaping setups typically use coils with resistances above one ohm, while sub-ohm vape turn carts involve lower resistance coils, allowing for higher power output and increased vapor production.

Benefits of Sub-Ohm Vaping:

  1. Enhanced Vapor Production: Sub-ohm vaping produces larger and denser vapor clouds compared to traditional vaping setups, providing a more immersive vaping experience.
  2. Intensified Flavor: Lower resistance coils can heat e-liquid more efficiently, resulting in richer and more pronounced flavor profiles.
  3. Warmer Vapor: Sub-ohm vaping often delivers warmer vapor temperatures, which some vapers find more satisfying and enjoyable.
  4. Customization Options: Sub-ohm vaping devices typically offer adjustable airflow, wattage, and temperature settings, allowing users to customize their vaping experience to their preferences.

Considerations for Sub-Ohm Vaping:

  1. Battery Safety: Sub-ohm vaping requires high-power batteries capable of handling the increased current draw. Use high-quality, high-drain batteries from reputable manufacturers and never exceed the battery’s amp limit to prevent safety hazards.
  2. E-Liquid Consumption: Sub-ohm vaping consumes e-liquid at a faster rate due to increased vapor production. Be prepared to refill your tank or drip more frequently, especially during extended vaping sessions.
  3. Airflow Adjustment: Proper airflow adjustment is crucial for sub-ohm vaping to prevent overheating and ensure smooth vapor production. Experiment with airflow settings to find the optimal balance between vapor density and flavor.
  4. Coil Compatibility: Not all vaping devices and tanks are suitable for sub-ohm vaping. Ensure your device and tank support sub-ohm coils and are compatible with high-power settings to avoid damage or malfunctions.
  5. Nicotine Strength: Sub-ohm vaping can deliver nicotine more efficiently due to increased vapor production and lung absorption. Consider lowering your nicotine strength to avoid nicotine overdose or discomfort.

How to Sub-Ohm Vape:

  1. Choose the Right Device: Select a vaping device specifically designed for sub-ohm vaping, such as a sub-ohm tank or a rebuildable atomizer (RDA) with a compatible mod.
  2. Select Sub-Ohm Coils: Use coils with resistances below one ohm designed for sub-ohm vaping. Most sub-ohm tanks come with pre-built coils, while RDAs require building your own coils with sub-ohm wire.
  3. Prime Coils: Before using a new coil, prime it by saturating the wicking material with e-liquid to prevent dry hits and ensure proper wicking.
  4. Adjust Wattage: Start with low wattage settings and gradually increase the power until you reach your desired vaping experience. Refer to the recommended wattage range provided by the coil manufacturer.
  5. Inhale Directly to Lung: Sub-ohm vaping typically involves inhaling vapor directly to the lungs (DL inhale) rather than mouth-to-lung (MTL) inhaling. Take long, slow draws to maximize vapor production and flavor intensity.
  6. Monitor Battery Life: Keep an eye on your battery life and recharge or replace batteries as needed to maintain optimal performance and prevent battery failure.
  7. Experiment and Enjoy: Sub-ohm vaping offers a wide range of customization options and vaping experiences. Experiment with different coil builds, wattage settings, and airflow adjustments to find what works best for you.


Sub-ohm vaping can provide a highly satisfying and immersive vaping experience, characterized by dense vapor clouds and intense flavor profiles. By understanding the principles of sub-ohm vaping, considering safety precautions, and following proper techniques, vapers can enjoy the benefits of sub-ohm vaping safely and responsibly. Whether you’re a seasoned vaper looking to enhance your vaping experience or a beginner curious about sub-ohm vaping, remember to prioritize safety and enjoy the journey of exploring new vaping possibilities.
