SMOK TFV18 Mini Sub-Ohm Tank
The SMOK TFV18 Mini Sub-Ohm Tank takes the cloud-chasing performance of the full-size TFV18 and packs it into a 28mm frame that sits properly on a mid-size mod. A 6.5mL bulb glass capacity means far fewer refills during long sessions, and the rotating top-fill system with a push-button lock opens with a press and a twist — no fiddling with sliding covers, and no accidental openings in a pocket. Built from 304 stainless steel with Pyrex glass reinforcement, it's designed to take daily knocks. Five copper braces on the base dissipate heat efficiently, keeping performance consistent through chain-vaping. The dual-slotted bottom airflow control ring feeds a bottom-to-top airflow path for a smooth, unrestricted direct-lung draw, and the press-fit V18 Mini coils swap in seconds with no threading. Ships with a 0.2Ω meshed coil pre-installed plus a spare 0.15Ω dual meshed FeCrAl coil, covering everything from 40W right up to 110W.

FAQ
Q: Do I need a mod for this tank?
A: Yes. This is a tank only — it has a threaded 510 connection and needs a 510-compatible mod. Given the coil range, you'll want a mod capable of at least 80W, ideally 110W or more to run the 0.15Ω coil properly.
Q: Are TFV18 Mini coils the same as regular TFV18 coils?
A: No. The Mini uses the V18 Mini coil series, which is a different size from the full-size TFV18 coils. Make sure you're ordering V18 Mini replacements.
Q: What's the difference between the two included coils?
A: The 0.2Ω meshed runs at 40–80W (best around 60W) — a good everyday coil with strong flavor and moderate battery drain. The 0.15Ω dual meshed FeCrAl runs at 80–110W (best around 90W) for denser vapor, but eats through e-liquid and battery faster.
Q: How do I fill it?
A: Press the button on the top cap and rotate to slide it open, fill through the port, then rotate it closed until it locks. The push-button lock stops the cap opening by itself in a pocket or bag.
Q: What e-liquid should I use?
A: High-VG freebase e-liquid, typically 70VG/30PG or thicker, at low nicotine strength — usually 3mg or 6mg. Do not use nicotine salts or high-nicotine e-liquid in a sub-ohm tank; the vapor output makes the nicotine delivery far too harsh.
Q: How do I change the coil?
A: The V18 Mini coils are press-fit — pull the old coil straight out of the base and push the new one in until it seats. No threading involved. Prime the new coil by dripping e-liquid onto the exposed cotton, then let it sit filled for ten minutes before vaping.
Q: Can I adjust the airflow?
A: Yes. Rotate the dual-slotted ring at the base to open or close the airflow slots. Fully open gives an airy direct-lung draw; closing it down tightens and warms the vape.
Q: Why is my tank leaking?
A: Most often an under-seated coil or a top cap that isn't fully locked. Also check that the tank isn't being left in a hot car or stored on its side with a nearly empty bulb glass — both encourage seepage through the airflow slots.
