Sub-Ohm Tank Buying Guide
If you’re looking for sub-ohm tanks, it’s important to choose the right one based on your vaping preferences. Sub-ohm tanks are designed for direct-to-lung (DTL) vaping, producing large vapor clouds and intense flavors. Here are the key factors to consider when purchasing a sub-ohm tank:
1. Coil Resistance & Wattage Range
- Sub-ohm tanks use coils with resistances below 1.0Ω, usually ranging from 0.15Ω to 0.6Ω.
- Check the recommended wattage range of the coils to match your mod’s power output.
- Lower resistance coils (e.g., 0.15Ω) require higher wattage and produce warmer vapor.
2. Airflow Control
- Adjustable airflow allows you to customize your vaping experience.
- Wide-open airflow is ideal for cloud chasing, while a restricted airflow enhances flavor.
3. E-Liquid Capacity
- Sub-ohm tanks typically hold between 2ml to 8ml of e-liquid.
- Larger tanks reduce the need for frequent refills but make the setup bulkier.
4. Coil Compatibility & Availability
- Ensure the tank supports widely available replacement coils.
- Some tanks are compatible with multiple coil types, allowing for versatility.
5. Wicking Material & E-Liquid Compatibility
- Most sub-ohm coils use organic cotton, but some advanced options feature mesh coils for better flavor and longevity.
- Use high-VG e-liquids (70% VG or higher) for smooth vapor production and to prevent coil burning.
6. Top-Fill vs. Bottom-Fill Design
- Top-fill tanks are more convenient and reduce leaking risks.
- Bottom-fill tanks require removal from the mod but may offer better e-liquid saturation.
7. Build Quality & Brand Reputation
- Choose reputable brands like SMOK, Vaporesso, Uwell, Freemax, and GeekVape for quality and durability.
- Stainless steel and pyrex glass tanks are more resistant to heat and damage.
8. Drip Tip Size
- Wide-bore drip tips enhance airflow and are preferred for sub-ohm vaping.
- Some tanks allow for custom drip tips for a personalized experience.
9. Leak Prevention Features
- Look for leak-resistant designs with sealed O-rings and top airflow systems.
- Proper coil installation and regular maintenance help prevent leaks.
10. Price & Value for Money
- Higher-end tanks offer better materials, coil longevity, and advanced airflow control.
- Budget-friendly options still provide a great experience but may lack premium features.
