What Is Sub-Ohm Vaping?
Sub-ohm vaping refers to using a coil with a resistance below 1.0 ohm. The lower resistance allows more electrical current to flow through the coil, which generates more heat and produces significantly more vapour and flavour compared to standard coils. It's the preferred style for vapers who enjoy big clouds and intense taste.
How Does It Differ from Standard Vaping?
Standard or "above-ohm" vaping uses coils with a resistance of 1.0 ohm or higher. These setups are typically used in pod systems and mouth-to-lung (MTL) devices, which produce less vapour and focus on a tighter, cigarette-like draw. Sub-ohm vaping, by contrast, uses a direct-to-lung (DTL) inhale — you breathe the vapour directly into your lungs like taking a deep breath.
Key Differences at a Glance
- Vapour production — Sub-ohm produces significantly more vapour.
- Flavour intensity — Lower resistance coils tend to deliver more intense flavour.
- Throat hit — Sub-ohm vaping has a smoother, less pronounced throat hit.
- E-liquid consumption — Sub-ohm devices use more e-liquid per session.
- Battery usage — Higher power draw means faster battery drain.
- Nicotine strength — Sub-ohm vapers typically use lower nicotine (3mg–6mg) because the increased vapour delivers more nicotine per puff.
What Equipment Do You Need?
To get started with sub-ohm vaping, you'll need:
- A sub-ohm capable device — Box mods and some advanced vape pens can handle sub-ohm coils. Make sure your device supports the wattage range required by your coil.
- A sub-ohm tank — These tanks have larger airflow openings and use coils rated below 1.0 ohm. Many come with adjustable airflow control.
- High-VG e-liquid — A 70VG/30PG ratio or higher is recommended. High-PG liquids can be too harsh when sub-ohm vaping.
- Quality batteries — Sub-ohm vaping draws more current from your batteries. Use high-drain batteries from reputable brands and follow proper battery safety practices.

Is Sub-Ohm Vaping Right for You?
Sub-ohm vaping is best suited for experienced vapers who want maximum flavour and cloud production. It's not typically recommended for beginners or those who prefer a tight, cigarette-style draw. If you're still new to vaping, start with a pod system or MTL device and work your way up once you're comfortable with the basics.
Safety Considerations
Sub-ohm vaping puts greater demands on your battery, so safety is important:
- Use regulated devices with built-in safety protections.
- Never exceed the recommended wattage range for your coil.
- Use batteries rated for high-drain applications.
- Don't use damaged batteries or wraps.
As long as you follow these guidelines and use quality equipment, sub-ohm vaping is a safe and enjoyable experience.
