Uwell WHIRL S2 Pod System
The Whirl S2 is a slim pen-style MTL kit that borrows two things most pod systems don’t have: a standard 510 mouthpiece fitment and a replaceable coil. A 900mAh battery drives up to 17W, set automatically by the installed coil, through a generous 3.5mL bottom-fill pod. Airflow is adjusted by simply rotating the pod in the body — no tiny sliders. The kit ships with both 0.8Ω and 1.2Ω coils plus a standard 510 drip tip and two cigarette-style fiber filter tips, so you can set the draw and the mouthfeel the way you want on day one. At 20 × 105mm and 39g in aluminum alloy and PCTG, it carries like a pen.

FAQ
Q: Do I replace the pod or the coil?
A: The coil. The pod is a refillable shell and the press-fit coil drops out and back in, so your ongoing cost is a coil rather than a whole cartridge. Replace the pod itself only if it cracks or the seals wear out.
Q: What are the fiber filter tips for?
A: They absorb condensate — the warm liquid that collects in the mouthpiece — so you don’t get droplets or spit-back, and they give a softer, more cigarette-like mouthfeel than hard plastic. Two come in the box; replacements are sold in 10-packs. They are not a health or nicotine filter.
Q: Can I use my own drip tip?
A: Yes. The pod takes a standard 510 mouthpiece, which is unusual for a pod system — any 510 drip tip will seat in it.
Q: Which coil should I use?
A: 1.2Ω for a tighter, cooler, more cigarette-like MTL draw with higher-strength salts. 0.8Ω runs a little warmer with more vapor. Both are in the box, so try each before restocking. Whirl S 0.8Ω coils also fit.
Q: How do I adjust the airflow?
A: Rotate the pod within the device body. There is no separate slider or ring — turning the pod lines the vents up tighter or wider.
Q: What e-liquid should I use?
A: 50VG/50PG nicotine salts at mid-to-high strength suit both coils. Avoid high-VG sub-ohm juice, which won’t wick properly through an MTL coil and will burn it. Fill through the plugged port on the pod base and let a new coil stand 5–10 minutes before the first draw.
