What is sub-ohm vaping?
Sub-ohm vaping generally refers to using coils below 1.0Ω and is commonly associated with more open airflow and higher-power, DTL-oriented setups. Exact output, coil range and tank configuration depend on the device.
Use the installed coil's stated resistance and manufacturer-recommended operating range when configuring the kit.
Dive into Intense Flavour Profiles
Mesh coils, adjustable output and airflow are common across many current sub-ohm devices, but features and supported modes vary. Compare the exact chipset, tank, coil and battery specifications for each model rather than treating all advanced kits as identical.
Designed for Direct-to-Lung (DTL) Vaping
Sub-ohm systems are commonly used for DTL-style vaping, but airflow, mouthpiece, output and coil choices vary. Choose liquid viscosity and nicotine strength according to the exact device, installed coil and manufacturer guidance.
Supporting categories include replacement coils, vape tanks, e-liquids and 70/30 shortfills where they are compatible with the installed coil. Do not choose a liquid or coil solely from the category name.
Current higher-powered examples include the Vaporesso Armour Max and Geekvape T200 Advance. Browse the Vaporesso range, Geekvape devices, adjustable mod setups or return to the wider kit range.
Vape Guides
What type of e-liquid should I use with a sub-ohm kit?
Use an e-liquid that is compatible with the installed tank and coil. Many sub-ohm coils are designed for higher-VG liquids, but the appropriate VG/PG ratio depends on the specific coil and manufacturer guidance.
What nicotine strength is suitable for sub-ohm vaping?
Nicotine strength should be chosen according to the exact device, coil, e-liquid product and manufacturer guidance. Avoid applying one fixed strength recommendation across every sub-ohm setup.
How do I find the best wattage for my sub-ohm kit?
Use the operating range specified for the installed coil and device. Start and adjust only within the manufacturer's recommended range rather than using a fixed wattage-increase rule.
How often should I change my sub-ohm coil?
The lifespan of a sub-ohm coil varies depending on several factors, like:
- Sweet or dark e-liquids clog coils more quickly
- Heavy vapers will need to change coils more often
- Vaping at higher wattages within the coil's range can shorten its life.
Are sub-ohm kits suitable for beginners?
No, sub-ohm kits are not recommended for someone without prior vaping experience because of required basic understanding of wattage, coil resistance, e-liquid types, and battery safety. Beginners might find simpler MTL starter kits or pod systems more forgiving to start with before transitioning to more powerful sub-ohm setups.
What's the difference between MTL and DTL vaping?
MTL vapour is drawn into the mouth first, held briefly, and then inhaled into the lungs just like a cigarette. It utilises higher resistance coils and higher nicotine strengths.. DTL vapour is drawn directly into the lungs in one continuous, open inhale, similar to inhaling from a shisha pipe. It requires lower nicotine strengths and produces large clouds.
Why is my sub-ohm tank leaking or spitting?
The common causes of leaking or spitting include:
- Using too thin an e-liquid
- Improper coil wicking or an old or faulty coil
- The tank components or coils are not screwed in tightly.
- Overfill the vape tank
- Worn or missing seals in the tank.
- Incorrect wattage setting, i.e. too low
What are the safety considerations for sub-ohm kits?
Safety measures are necessary with sub-ohm kits due to higher power outputs and often external batteries:
- Battery Safety: Use high-quality, authentic batteries (e.g., 18650, 21700) from reputable brands. Always use matched pairs for dual-battery mods, keep batteries in protective cases when not in use, and replace damaged battery wraps immediately.
- Ohm's Law: While modern mods have safety chips, understanding basic Ohm's Law (relationship between voltage, current, resistance, and wattage) is beneficial.
- Coil Compatibility: Always use coils within your device's and mod's supported resistance range.
- E-liquid Usage: Use appropriate high VG e-liquids.
- Charging: Charge external batteries with a dedicated external charger for safety and longevity.
How long do external batteries last in advanced kits?
External-battery runtime depends on battery capacity and condition, device output, coil, settings and use. Follow the battery and device manufacturer's guidance and do not assume a single- and dual-battery setup will have a fixed runtime relationship.
Can I use nicotine salts in a sub-ohm kit?
E-liquid and nicotine compatibility depends on the exact sub-ohm device, coil and product formulation. Check the coil/device guidance and the e-liquid instructions rather than assuming every nicotine-salt product is suitable or unsuitable for the whole category.
