SMOK TF-D Tank is a refillable 5ml tank system designed for higher power devices, allowing users to tailor their experience using their preferred e-liquid while supporting gradual titration.

The tank supports both 0.15Ω and 0.4Ω SMOK D-Coils, which are best suited to freebase nicotine formulations typically used by patients managing long-term nicotine dependence. Recommended wattage ranges are 55–65W for the 0.15Ω coil and 25–35W for the 0.4Ω coil.

Constructed from stainless steel with a resin tube, the tank is designed as an alternative to traditional glass tanks to help reduce breakage and replacement requirements. It features a top-fill system for quick and clean refilling, along with adjustable dual top airflow to allow for a more tailored inhalation experience.

The tank uses a press-fit coil installation system with a threaded 510 connection and features a 25.2mm diameter with an 810 drip tip. The draw style is direct-to-lung (DTL).
