Uwell Caliburn G3 GPP Replacement Pods XL

One pod platform, sixteen compatible devices. The Caliburn GPP cartridges are Uwell's cross-compatible Replacement Pods for the entire Caliburn G3, G4, and G5 series. Four resistance options in the store picker: 0.4ohm, 0.6ohm, 0.9ohm, and 1.2ohm.

Refillable 2ml capacity (UK TPD), mesh coil construction, and Uwell's U² anti-leak technology built into every pod. The lower resistances use a top-fill design for RDL vaping; the higher resistances use side-fill for MTL. Pack of four. Works with freebase and nic salt e-liquids. Over 18s only.

Why vapers choose the Caliburn GPP pods:

• One pod fits sixteen devices across the Caliburn G3, G4, and G5 families, which means you never need to worry about ordering the wrong pod for your specific Caliburn model

• Four resistance options covering MTL and RDL in the same pod format, so you can switch vaping styles without switching devices

• U² anti-leak technology uses ultrasonic welding and a U-shaped airflow channel to improve leak protection by 150% over previous Caliburn pod generations

• PRO-FOCS flavour optimisation is Uwell's proprietary coil testing process, designed to preserve the original flavour profile of your e-liquid rather than adding a coil taste

• Pack of four keeps you stocked for weeks, especially useful if you rotate between MTL and RDL pods depending on the situation

Caliburn G3 GPP Replacement Pods Features

U² Anti-Leak Technology Actually Works

Leaking pods ruin devices and waste liquid. Uwell's U² system attacks the problem from two angles. Ultrasonic welding seals the pod housing tighter than conventional adhesive bonding, eliminating the micro-gaps where liquid typically escapes. 

The U-shaped airflow channel redirects condensation away from the connection point and back into the pod chamber. Uwell claims a 150% improvement in leak resistance over earlier Caliburn pods. In practical terms, that means a Refillable Pod Kit that you can actually carry in your pocket without worrying about liquid seeping onto the battery contacts.

PRO-FOCS: The Coil Tech Behind the Flavour

Most mesh coils produce good flavour. Uwell's PRO-FOCS (flavour optimisation control system) is about consistency. Each coil undergoes testing during production to ensure it delivers the flavour profile of the e-liquid as accurately as possible, without the metallic or cottony taste that cheaper coils sometimes introduce on first fill. 

The result is a cleaner break-in period. Your first few puffs on a fresh Caliburn GPP pod taste closer to the liquid's intended profile rather than requiring several fills before the coil settles.

Two Fill Methods, Matched to the Resistance

The 0.4ohm and 0.6ohm pods use a top-fill design. Lift the mouthpiece, fill directly into the pod. Fast, clean, and easy to see the liquid level as you pour. The 0.9ohm and 1.2ohm pods use side-fill. Open the silicone stopper on the side and fill from there. 

Both methods are designed to minimise spills, but the top-fill approach on the RDL pods is the slightly quicker process. Neither method involves removing the pod from the device to refill, which keeps things convenient.

Magnetic Connection Removes the Guesswork

The GPP pods snap into any compatible Caliburn device magnetically. No screw threads that cross, no press-fit tolerances that loosen over time. Pull the spent pod out, click a fresh one in. The magnetic alignment ensures the pod sits correctly every time, which matters because a poorly seated pod creates air leaks, reduces flavour, and causes the device to misfire.

Four Resistances Cover Every Vaping Style

0.4ohm runs warmest and produces the most vapour. Best with freebase liquid at lower nicotine strengths. 0.6ohm sits in the RDL middle ground: warm flavour, moderate clouds, good with freebase at 3mg to 6mg. 

0.9ohm tightens the draw noticeably and works well with both freebase and nic salts at 10mg to 20mg. 1.2ohm delivers the tightest MTL draw, closest to a cigarette, and pairs best with nic salt at 20mg. One device, four different experiences depending on which pod you click in.

Caliburn G3 GPP Pods Resistance Options

Four options. The resistance you choose determines your draw style, vapour production, throat hit, and which e-liquid works best. All four use Uwell's mesh coil construction.

The most popular starting point is the 0.9ohm. It offers a comfortable MTL draw with enough restriction to satisfy ex-smokers, and it pairs well with both 50/50 Freebase and nic salt at 10mg or 20mg. If you are not sure which to pick, this is the safe bet.

For a slightly looser, warmer draw with more flavour intensity: the 0.6ohm. Still manageable for MTL vapers who want a touch more openness, and it works well with 50/50 or slightly Higher VG Freebase liquid at 3mg to 6mg.

For genuine RDL cloud production: the 0.4ohm. Warmer vapour, bigger clouds, and best suited to freebase e-liquid at lower nicotine strengths. This is the pod for vapers who want more from their Caliburn without switching to a different device.

For the tightest possible draw: the 1.2ohm. Closest to a cigarette-style pull. Minimal vapour, strong throat hit, and ideally paired with 20mg Nic Salt. Efficient on liquid and battery.

How to Set Up the Caliburn G3 GPP Pods

1. Remove a fresh pod from the pack. Check the resistance printed on the pod matches what you want.

2. Open the fill port. For the 0.4ohm and 0.6ohm: lift the mouthpiece to access the top-fill opening. For the 0.9ohm and 1.2ohm: pull open the silicone stopper on the side of the pod.

3. Fill with your chosen e-liquid to just below the maximum line. Avoid overfilling. Keep the nozzle away from the central airflow tube if using top-fill.

4. Close the fill port securely. Press the mouthpiece back down or reseal the silicone stopper until it sits flush.

5. Let the liquid soak into the mesh coil for three to five minutes. Do not rush this. The mesh wicking needs time to fully saturate. Firing before the wick is ready produces a dry, burnt taste and shortens the coil's usable life significantly.

6. Click the pod into your Caliburn device. The magnetic connection snaps it into place. Take a couple of gentle primer puffs, then vape normally.

What's in the Caliburn G3 GPP Pods Box

Four refillable 2ml pods in your chosen resistance. No e-liquid, no device, no Vape Accessories. Just the pods. Each pod has its mesh coil built in. When the coil degrades, you replace the entire pod rather than swapping an internal coil head.

Compatible With the Entire Caliburn G3, G4, and G5 Range

The GPP designation means these pods fit every Caliburn device built on the G Pod Platform. That is a long list: 

• Caliburn G3, 

• G3 Lite, 

• G3 Lite Koko, 

• G3 ECO, 

• G3 Pro, 

• G3 Pro Koko, 

• GK3, 

• GK3 Tenet, 

• G4, 

• G4 Mini, 

• G4 Pro, 

• G4 Classic, 

• G4 Pro Koko, 

• G5 Lite, 

• G5 Lite SE, 

• and G5 Lite Koko. 

Sixteen devices and counting, with Uwell adding more GPP-compatible models as the platform expands.

What they do not fit: the Caliburn G2, Caliburn G, Caliburn A2, Caliburn A3, Caliburn KOKO, or any non-GPP Uwell Device. Those use entirely different pod formats. If the packaging on your current Caliburn pods says "GPP," these are the replacements.

About Uwell

Uwell is one of the most established names in the UK pod kit market, and the Caliburn series is the reason why. The original Caliburn set the standard for compact, affordable, high-flavour pod vaping, and every generation since has iterated on that formula. 

The GPP platform represents Uwell's commitment to cross-device compatibility: rather than forcing customers to buy new pods every time a new Caliburn launches, the GPP cartridge system works across G3, G4, and G5 devices. The U² anti-leak technology and PRO-FOCS flavour system are Uwell's headline coil innovations, and both are built into every GPP pod in this pack.

Stock Up and Save

Four pods per pack. At daily use, each pod lasts roughly seven to ten days before the mesh coil degrades and flavour starts to drop. A single pack covers you for about a month. 

Picking up two packs at once means you are sorted for two months without reordering, and you can mix resistances to keep options open: a pack of 0.9ohm for weekday nic salt use and a pack of 0.6ohm for weekend freebase sessions, for example. 

Pirate Vapes dispatches every order the same day before 4 pm in padded packaging. TPD compliant, age-verified checkout, over 18s only. Orders over £25 ship free with Free Pirate Post.

Conclusion

The Caliburn G3 GPP pods give you four resistance options, two fill methods, U² anti-leak technology, PRO-FOCS flavour optimisation, and magnetic click-in installation across sixteen compatible Caliburn devices. MTL or RDL. 

Nic salt or freebase. 2ml TPD-compliant capacity. Pack of four for ongoing value. If you own any Caliburn from the G3 series onward, these are the pods. Browse more from the Uwell collection or head back to Pirate Vapes to keep exploring.

FAQs

Which Caliburn devices do the GPP pods fit?

Every Caliburn built on the G Pod Platform. That includes the G3, G3 Lite, G3 Pro, GK3, G4, G4 Mini, G4 Pro, G5 Lite, and their Koko variants. They do not fit the Caliburn G2, G, A2, A3, or original KOKO.

How long does each GPP pod last?

Roughly seven to ten days with daily use. Sweeter e-liquids will shorten the lifespan as sugar residue builds up on the mesh faster. Lighter vapers may get two weeks.

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

The 0.4ohm and 0.6ohm pods use top-fill: lift the mouthpiece to access the fill port. The 0.9ohm and 1.2ohm pods use side-fill: open a silicone stopper on the side. Both methods work well. The fill design is matched to the resistance, not a selectable option.

Can I use nic salt in the 0.4ohm pod?

Not recommended. The 0.4ohm runs at higher wattage and produces warmer vapour, which makes 20mg nic salt uncomfortably harsh. Stick to freebase at 3mg to 6mg for the 0.4ohm. Use the 0.9ohm or 1.2ohm for nic salt.

Are GPP pods the same as Caliburn G3 pods?

Yes. GPP is Uwell's platform name for the Caliburn G3 series pods onward. If your current pods are marked "GPP" on the packaging, these are the direct replacement.

Do the pods come with e-liquid?

No. These are empty, refillable pods. You fill them with your own e-liquid. Compatible with 50/50 VG/PG, high PG blends, freebase, and nic salt.
