How Sub-Ohm Tanks Work
A sub-ohm tank is a refillable tank that uses coils rated below 1.0 ohm for direct-to-lung (DTL) vaping at higher wattages. The low resistance and large mesh coil vaporise more e-liquid per puff, giving the warm, thick clouds and intense flavour sub-ohm is known for. Sub-ohm tanks pair with high VG shortfill (70/30 or 80/20), not nic salts, and screw onto any 510 box mod.
When the flavour fades you swap the coil rather than the tank - find yours in the sub-ohm coils collection. For the device itself, see our sub-ohm vape kits or standalone vape mods.
Choosing the Best Sub-Ohm Tank
Three things separate one sub-ohm tank from the next:
- Airflow - adjustable airflow tunes the draw from a tighter DTL to a wide-open cloud, and top airflow designs let air in above the glass for a smoother pull.
- Coil range - check the tank takes the mesh coils you want across the resistances and wattages you vape at.
- Fit - every sub-ohm tank here uses the standard 510 connection, so it sits on any box mod.
Leak-Resistant and High-Capacity Sub-Ohm Tanks
The sub-ohm tanks that stay leak-free are the top-fill, top airflow designs with good seals - filling from the top keeps e-liquid away from the airflow, and air entering above the glass means far less chance of a leak in your pocket.
On capacity, UK sub-ohm tanks ship at the 2ml TPD limit as standard, with larger bubble glass available on many models for fewer refills. If you want a big tank for all-day vaping, look for one supplied with a bubble-glass section. Whatever you pick, the right sub-ohm tank gives the clouds, flavour and leak-free run that DTL vaping is about, from the latest releases down to cheaper tanks that still perform.
