Uwell Whirl 2 Sub-Ohm Tank

A 25mm tank built for both MTL and DTL vaping, with a 3.5ml capacity, 304 stainless steel construction, and Uwell’s Pro-FOCS coil technology. The Whirl 2 ships with two coils: a 1.8Ω single coil for a tight mouth-to-lung draw at 10 to 15W, and a 0.6Ω dual coil for a looser direct-to-lung hit at 18 to 22W. 

Quarter-turn top fill, dual slotted adjustable airflow with five bored holes, and a curved top cap that wraps around the glass to protect it from knocks. Thread it onto any 510 mod, and it runs. Pirate Vapes ships the Whirl 2 tracked with age-verified UK delivery.

Why do vapers choose this:

• MTL and DTL in one tank. The 1.8Ω coil gives a tight, cigarette-style draw at low wattage. The 0.6Ω coil opens things up for a looser lung hit with more vapour. Swap the coil, adjust the airflow, and the tank changes character completely. No need to own two tanks for two vaping styles.

• Pro-FOCS coil technology. Uwell’s proprietary flavour-testing system ensures each coil meets a consistent performance standard. The result is reliable flavour from coil to coil, with fewer duds in a pack than you get with some brands.

• Glass protection built into the design. The curved top cap and the airflow control ring both extend past the glass, creating a physical shield around it. A bump on a table edge hits the steel, not the glass. It is a small detail that matters when the tank lives in your pocket.

• 3.5ml capacity. Larger than most 2ml TPD tanks without being oversized. Fewer refills through the day, especially on the 1.8Ω MTL coil where e-liquid consumption is low.

• Two coils and a spare glass in the box. Both coils included, plus an extra glass tube and replacement O-rings. You have everything you need to start vaping and a backup for when something breaks.

Uwell Whirl 2 Sub-Ohm Tank Features

Dual Coil System: MTL and DTL

The 1.8Ω single coil runs at 10 to 15W and is designed for mouth-to-lung vaping. It produces minimal vapour, delivers a firm throat hit, and works well with higher-nicotine freebase liquids. The draw is tight and controlled, close to a cigarette. The 0.6Ω dual coil runs at 18 to 22W and opens the draw for direct-to-lung vaping. More vapour, more flavour intensity, and a warmer hit. Both coils use Uwell’s Pro-FOCS technology for consistent performance.

Adjustable Airflow with Five Bored Holes

The airflow control ring at the base of the tank has dual slots with five differently sized bored holes. Rotate the ring to open or close the airflow incrementally. Fully closed gives a tight MTL draw. Fully open gives a loose DTL inhale. Anywhere in between gives a restricted draw that sits between the two styles. The airflow is smooth, with no rattling or stiffness, and holds its position once set.

Quarter-Turn Top Fill

A quarter-turn of the top cap reveals the fill port. No unscrewing, no removing the drip tip, no fiddling with silicone plugs. The mechanism is quick, straightforward, and designed to minimise spills. The lower-profile design of the Whirl 2 also means vapour travels a shorter distance from coil to drip tip, which helps preserve flavour accuracy.

Curved Glass Protection

The top cap and the airflow ring at the base both curve around the glass section, creating a concave profile that recesses the glass below the level of the steel. If the tank takes a knock, the metal absorbs the impact instead of the glass. It is a practical design choice for a tank that gets carried in pockets and bags daily.

What E-Liquid to Use

High VG e-liquids work best with both coils. 60/40 VG/PG or thicker. For the 1.8Ω MTL coil, you can also use 50/50 freebase or higher-PG blends at higher nicotine strengths (up to 18mg). For the 0.6Ω DTL coil, stick with High-VG Shortfills at 6mg nicotine or lower.

Do not put nic salts through the 0.6Ω DTL coil. The higher wattage and open draw will deliver too much nicotine too fast. Browse our E-liquid Range at Pirate Vapes for shortfills and 50/50 liquids that pair well with the Whirl 2.

How to Set Up the Uwell Whirl 2

1. Unscrew the base of the tank and make sure the pre-installed 1.8Ω coil is pressed firmly into place.

2. Drip 3–4 drops of e-liquid directly onto the exposed cotton ports on the side of the coil.

3. Screw the tank base back together, then thread the 510 connection onto your mod until snug.

4. Give the top cap a quarter-turn to remove it, fill the 3.5ml reservoir through the port, and twist the cap back on to lock it.

5. Let the tank sit undisturbed to let the Pro-FOCS wicking material fully saturate.

6. Set your mod between 10–15W for the pre-installed 1.8Ω MTL coil (or 18–22W if you swap to the 0.6Ω DTL coil).

7. Rotate the bottom ring to select your preferred airflow holes, and you are ready to go.

Compatibility

The Uwell Whirl 2 uses a standard 510 threaded connection. It fits the vast majority of vape mods on the market. The 0.6Ω coil needs a mod that can fire at 18 to 22W. The 1.8Ω coil needs a mod that can fire at 10 to 15W. Both wattage ranges are within the output of almost any regulated mod. The tank uses Uwell Whirl coils only.

Not Uwell Crown coils, not Uwell Caliburn coils. Make sure you order the correct coils when restocking. Pirate Vapes stocks the Whirl 2 tank and the Uwell Whirl replacement coils together in our Uwell Range.

About Uwell

Uwell is best known in the UK for the Crown and Caliburn lines, but the Whirl series is where the brand’s MTL and crossover tanks live. The original Whirl tank was a bestseller for mouth-to-lung vapers, and the Whirl 2 builds on that with a revised airflow system, a dual-coil option for DTL, and Pro-FOCS technology for more consistent flavour.

It is one of the few tanks on the market that genuinely works for both MTL and DTL without compromise, which makes it a strong choice for vapers who want flexibility without owning multiple setups.

Stock Up and Save

The tank ships with two coils, but they will not last forever. Having a pack of Uwell Whirl replacement coils ready means you are never stuck on a burnt coil with a tank you cannot use. Add a shortfill or a bottle of 50/50 alongside the coils and your order is sorted.

Pirate Vapes sends everything in plain packaging, tracked to your door, age-verified checkout, 18+ delivery. Crew Rewards points go on every order. If you want coils arriving without thinking about it, set up The Crow’s Nest at Pirate Vapes and they come on repeat with a saving.

How do I change the coil?

Pull the old coil out of the base of the tank. Push the new one in until it seats. Prime it with a few drops of e-liquid, fill the tank, and wait five minutes before vaping.

Does Pirate Vapes stock the replacement coils?

Yes. Uwell Whirl replacement coils are in our Uwell range at Pirate Vapes.
