What is a sub-ohm vape device?
Sub-ohm devices are vaping setups with coils that have a resistance below 1.0 ohm. They are designed to produce large vapor clouds and enhanced flavour by using high wattage and direct-to-lung (DTL) vaping.
Who should use sub-ohm vape devices?
Sub-ohm vaping is ideal for experienced vapers who enjoy intense flavour, massive clouds, and customizable vaping. Beginners may want to start with simpler devices before transitioning to sub-ohm devices.
What is the difference between sub-ohm vaping and regular vaping?
Sub-ohm vaping utilizes low-resistance coils and high wattage settings to produce high temperatures, resulting in larger vapor production and bolder flavors. Regular vaping typically uses higher-resistance coils for modest vapor output and mouth-to-lung (MTL) vaping.
Do I need special e-liquids for sub-ohm vaping?
Yes! Sub-ohm devices work best with e-liquids that have a higher VG (Vegetable Glycerin) ratio (e.g., 70% VG or more). High-VG liquids produce smoother vapor and larger clouds. They are also designed for lower nicotine strengths (usually 3mg or 6mg).
Why are low nicotine levels recommended for sub-ohm vaping?
Because sub-ohm devices vaporize larger amounts of e-liquid, the nicotine concentration per inhale is significantly higher. Using low nicotine levels prevents harshness and excessive intake, creating a smoother experience.
What is direct-to-lung (DTL) vaping?
Direct-to-lung vaping involves inhaling vapor directly into your lungs, bypassing the mouth. Sub-ohm devices are optimized for DTL vaping due to their high vapor production.
What are the benefits of sub-ohm vaping?
Massive Vapor Production: Perfect for cloud chasers.
Enhanced Flavour: Sub-ohm devices deliver bold, distinct flavours.
Customizability: With variable wattage and temperature settings, vapers can personalise their experience.
Do sub-ohm vape devices consume more e-liquid?
Yes, sub-ohm vaping consumes e-liquid faster because of the higher wattage and larger vapor output.
Are sub-ohm devices safe to use?
Sub-ohm devices are safe when properly maintained and used as directed. Ensure you follow battery safety guidelines, choose quality coils and e-liquids, and use compatible components.
What kind of batteries do sub-ohm vape devices use?
Most sub-ohm devices use external rechargeable batteries, typically 18650, 20700, or 21700 batteries, depending on the model. Ensure your batteries can handle the high wattage sub-ohm vaping requires.
Is sub-ohm vaping more expensive than regular vaping?
Sub-ohm vaping can be more expensive because it uses more e-liquid, high-wattage coils, and requires powerful hardware. However, the enhanced experience often makes it worthwhile for enthusiasts.
Can I switch between sub-ohm and standard coils in my device?
Many devices allow you to switch between sub-ohm coils and higher-resistance coils, offering flexibility based on your vaping preferences.
How do I maintain my sub-ohm device?
Clean the tank regularly.
Replace coils as needed (usually every 1–2 weeks, depending on usage).
Ensure battery terminals are clean and properly installed.
Use high-quality e-liquids to prevent coil gunk.
Why is my sub-ohm tank leaking?
Leaking can happen if:
The tank is overfilled.
The coil is improperly installed.
The seals are damaged or worn.
Ensure proper assembly and use the appropriate VG/PG ratio e-liquid.
What wattage should I use with my sub-ohm coil?
Sub-ohm coils usually operate best in higher wattage ranges (e.g., 30–100W, depending on the coil's rating). Refer to the coil packaging for specific recommendations.
Why is my vapour too hot or harsh?
This happens when the wattage is set too high for the coil or your e-liquid has too much PG or nicotine. Lower the wattage or switch to a higher-VG e-liquid for a smoother experience.
How often should I replace sub-ohm coils?
On average, coils should be replaced every 1–2 weeks, depending on how heavily you vape. Signs a coil needs replacing include burnt or muted flavours and reduced vapor production.
Can I use pre-filled pods with sub-ohm devices?
No, sub-ohm devices use refillable tanks and specialised sub-ohm coils. Pre-filled pods are incompatible with sub-ohm vaping setups.
Are sub-ohm devices portable?
While sub-ohm devices can be portable, they are larger and bulkier compared to pod systems or vape pens. They are designed more for performance than portability.
How do I choose the right sub-ohm device?
Consider:
Power Output: Higher wattage devices offer better cloud production.
Battery Life: If you vape heavily, opt for devices with long-lasting batteries or external options.
Tank Capacity: A larger tank means fewer refills.
Features: Adjustable airflow and temperature control features allow for more customisation.
