What Is Sub-Ohm Vaping? Everything You Need to Know

If you’ve ever seen someone blowing huge, dense clouds of vapour, chances are they’re sub-ohm vaping. But what exactly is sub-ohm vaping — and is it right for you? 

In this guide, we’ll break down what sub-ohm vaping means, how it differs from MTL (mouth-to-lung) vaping, who it’s best suited for, and what you need to get started. 

🔍 What Is Sub-Ohm Vaping?

Sub-ohm vaping refers to vaping with a coil that has a resistance below 0.6 ohm. The lower the resistance, the more power (wattage) your device can push through the coil — which results in more vapour, more heat, and more flavour

This style of vaping is designed for direct-to-lung (DTL) inhales, similar to taking a deep breath in through a straw. 

Key Features:

  • Big cloud production
  • Intense flavour
  • Lower nicotine strengths
  • Higher wattage
  • Best used with high-VG e-liquids (usually 70VG/30PG)

✅ Who Is Sub-Ohm Vaping Best For?


Sub-ohm vaping is ideal for: 

  • Vapers who want more vapour and flavour
  • Those who have already quit smoking
  • People who enjoy customisation and power
  • Users who prefer low nicotine or nicotine-free vaping 
  • Hobbyists who enjoy trying different coil builds and settings


It’s not recommended for complete beginners or people who need higher nicotine levels to curb cravings. 

🔧 What Do You Need for Sub-Ohm Vaping?


To start sub-ohm vaping, you’ll need the right setup: 

  • ✅ A sub-ohm vape kit or mod that can handle high wattage 
  • ✅ A sub-ohm tank with coils below 1.0 ohm 
  • ✅ High-VG e-liquid (usually 70VG/30PG or higher) 
  • ✅ Batteries and safety knowledge (if using external battery mods)

💨 What to Expect with Sub-Ohm Vaping


Here’s what you’ll likely notice when switching to sub-ohm: 

  • Denser vapour – You’ll exhale large clouds 
  • Warmer vapour – Due to higher wattage 
  • Richer flavour – The extra heat brings out more from your e-liquid 
  • More e-liquid usage – You’ll go through juice faster 
  • Lower nicotine needed – Because of increased vapour volume 


Many sub-ohm vapers use 3mg or even 0mg nicotine — higher strengths can feel harsh with the direct-lung inhale. 

⚠️ Tips & Safety for Sub-Ohm Vaping

  • 🔋 Make sure your batteries and device can handle high power levels 
  • 💧 Keep your tank topped up to avoid dry hits 
  • 🌬 Use airflow control to customise your draw 
  • 📏 Stick to the recommended wattage range printed on the coil 
  • 🚫 Don’t use nic salts or high-nic e-liquids with sub-ohm coils 

Final Thoughts


Sub-ohm vaping is all about flavour, clouds, and performance. It’s a natural progression for many vapers once they move past the beginner stage — but it’s not for everyone. 


If you’re happy with a simple MTL device and high nicotine strength, that’s totally fine. But if you’re ready for bigger clouds and more customisation, sub-ohm might be the next step in your vaping journey.
