Uwell Caliburn A2 Replacement Pods

The pod that made the Caliburn A2 one of the UK's bestselling MTL kits. Sold in 4-packs with a built-in Meshed-H coil sealed inside each pod. Two resistances available: the 0.9-ohm with top-fill access, and the 1.2-ohm with side-fill access.

Both hold 2ml of e-liquid (TPD), both fit the Caliburn A2, AK2, and A2S kits, and both use Uwell's Pro-FOCS technology to regulate heat and bring out flavour. The coil is non-replaceable. When it fades, you bin the pod and click in a fresh one. Fill with nic salt or 50/50. Pirate Vapes stocks both resistances. TPD compliant. Over 18s only.

Why vapers choose Uwell Caliburn A2 Replacement Pods:

• 4-pack covers a month or more. Each pod lasts one to two weeks for most daily vapers. A single 4-pack keeps you going for four to eight weeks without reordering.

• Pro-FOCS flavour technology regulates heat in real time. The system cycles airflow through the coil chamber to control temperature and reduce dry hits, which keeps the flavour consistent deeper into the pod's life than standard mesh.

• Two fill methods across two resistances. The 0.9-ohm opens from the top (snap off the mouthpiece). The 1.2-ohm fills from the side (pull the rubber bung). Pick the resistance you prefer, and the fill method comes with it.

• PCTG body with a viewing window. You can see exactly how much liquid remains without pulling the pod out of the device. No surprises, no dry hits from an empty pod.

• Magnetic fit clicks in instantly. No threading, no twisting. Push the pod toward the device and the magnets grab it. Pull to remove. Two seconds either way.

Uwell Caliburn A2 Replacement Pods Features

Meshed-H Coil with Pro-FOCS Technology

The Meshed-H mesh coil inside each pod heats e-liquid across a wider surface than round wire, which means more even vapourisation and stronger flavour per puff. Uwell's Pro-FOCS system sits on top of that, recycling drawn airflow through the coil chamber to manage temperature. The result: flavour stays accurate for longer and dry hits are less frequent, even when the liquid level gets low.

Top-Fill or Side-Fill Depending on Resistance

0.9-ohm pods fill from the top. Snap off the black mouthpiece cap to expose the fill port. Easy, clean, one-handed. 1.2-ohm pods fill from the side. Pull the small rubber bung out, angle your bottle, and fill through the side port. Both methods are straightforward, but the top-fill 0.9 is faster for on-the-go refills.

Viewing Window for Liquid Level Monitoring

Each pod has a clear section built into the body that shows how much e-liquid is left. You do not need to remove the pod from the device to check. When the liquid drops below the coil openings, it is time to refill. This simple visibility prevents dry hits and extends the life of each pod by catching low levels before the wick runs dry.

Sealed Coil Design with No Maintenance

The coil is locked inside the pod at the factory. There is nothing to unscrew, thread, or replace. When the flavour starts to taste flat or slightly burnt, throw the pod away and click a new one in from your 4-pack. The entire maintenance routine takes ten seconds. No tools, no spare coils, no cleaning.

Magnetic Pod Connection for the Caliburn A2 Family

The pod sits in the device via magnetic contacts on the base. The fit is firm enough to hold during pocket carry but loose enough to pull out with two fingers. The connection is shared across the Caliburn A2, AK2, and A2S only. These pods do not fit any other Caliburn device (original, KOKO, G-series, or A3-series).

Uwell Caliburn A2 Replacement Pods Recommended E-Liquids

Refillable MTL Pods that pair best with nic salts and 50/50 blends. High VG (70/30 or thicker) is too viscous for the Meshed-H coil and will cause dry hits. The Caliburn A2 built its reputation on clean nic salt flavour at low wattage, so stick to thin liquids for the best results. Top picks from the Pirate Vapes e-liquids collection:

Best Pairings:

• Bar Juice 5000: Clean, accurate profiles that shine at 12-15W through mesh

• Elfliq: Elf Bar flavour profiles in nic salt form, natural fit for the A2's tight draw

• SKE Crystal Salts: Berry and ice blends that stay sharp in a 0.9-ohm pod

• Dinner Lady Salts: Dessert and tobacco depth at low wattage, smooth finish

Also Worth Trying:

• Hayati Pro Max Nic Salts: Full Hayati flavours, solid with the 0.9 pod

• Vampire Vape: Heisenberg through the 1.2 for a cool, tight pull

• Pod Salt: Wide range, reliable consistency across both resistances

• Doozy Salts: Sweet flavours that do not wreck the coil as fast as some alternatives

How to Set Up the Uwell Caliburn A2 Replacement Pods

1. Unpack. Take a fresh pod from the 4-pack.

2. Fill (0.9-ohm). Snap the black mouthpiece cap off the top of the pod. Squeeze your nic salt or 50/50 e-liquid through the fill port up to the line. Press the cap firmly back on.

3. Fill (1.2-ohm). Pull the rubber bung from the side of the pod. Angle your bottle and fill through the side port. Push the bung back in firmly.

4. Prime. Let the filled pod sit upright for five to ten minutes. The Meshed-H coil needs to soak. Skipping this step risks a burnt first puff.

5. Optional dry draw. Before inserting, take 4-5 draws on the pod without it in the device to help pull liquid into the coil (this is recommended for the A2).

6. Insert. Push the pod into the Caliburn A2 device. The magnets secure it automatically.

7. Vape. Inhale through the mouthpiece (auto-draw) or press the fire button. The device auto-sets the wattage.

What's in the Uwell Caliburn A2 Replacement Pods Box

Each pack contains four identical pods at your chosen resistance (either 0.9 ohm or 1.2 ohm). Every pod has a Meshed-H coil sealed inside, a 2ml capacity, a PCTG body with a viewing window, and magnetic contacts on the base. No device, no e-liquid, no cable included. The pods are the only contents.

About Uwell

Uwell launched in 2015 and the Caliburn range is the product line that made their name in the UK. The original Caliburn was one of the first pod kits to prove that a simple, refillable device could deliver genuine nic salt flavour without complexity. The A2 continued that approach: draw-activated, compact, and paired with mesh pods that prioritise flavour over cloud.

Pro-FOCS technology and Meshed-H coils are Uwell-developed. The Caliburn family now spans over a dozen devices, but the A2 pods remain one of the most popular replacement pod lines in UK vape shops. Browse the full Uwell Vapes collection at Pirate Vapes.

Conclusion

Four pods per pack. Sealed mesh coil. Top-fill or side-fill. One to two weeks per pod. The Uwell Caliburn A2 replacement pods do one thing and do it well: deliver clean nic salt flavour at low wattage without any maintenance. The 0.9-ohm is the standard choice. The 1.2-ohm tightens the draw further for vapers who want the closest thing to a cigarette pull.

Both fit the Caliburn A2, AK2, and A2S, and nothing else. Grab a pack from Pirate Vapes and pair with your favourite nic salt from our replacement pods collection.

FAQs

Which resistance should I buy? 

0.9 ohm for most vapers. Standard MTL draw, good flavour, the pod the A2 was designed around. The 1.2 ohm is for vapers who want a tighter, cooler draw closer to a cigarette.

What is the difference between top-fill and side-fill? 

The 0.9-ohm pods fill from the top (snap off the mouthpiece cap). The 1.2-ohm pods fill from the side (pull a rubber bung). Both are straightforward. The top-fill is faster for quick refills.

What is Pro-FOCS? 

Uwell's proprietary flavour technology. It recycles drawn airflow through the coil chamber to regulate temperature and extract more flavour from your e-liquid. The practical difference: flavour holds up longer into each pod's lifespan.

Can I use high VG e-liquid? 

Not recommended. The Meshed-H coil wicks best with nic salts and 50/50 blends. High VG (70/30 or thicker) is too viscous and will cause dry hits or gurgling.

Do these leak? 

The A2 pods have an anti-leak design, but overfilling is the most common cause of moisture at the base. Fill to the line, not past it, and make sure the mouthpiece cap or side bung is firmly closed. Some reviews mention occasional leaking, so do not overfill.

Are these genuine Uwell? 

Every pack sold through Pirate Vapes is genuine Uwell, sourced via verified UK distribution. TPD-compliant, MHRA-notified, sold through age-verified checkout. Over 18s only.
