Caliburn Kits, Replacement Pods and Coils by Pod Family
Uwell Caliburn replacement parts use different pod and coil systems. Some cartridges have built-in coils, while other devices use separate replacement coils.
Caliburn G3, G4 and G5 kits
Uwell Caliburn G3, G4 and G5 kits use the G Pod Platform (GPP). These refillable cartridges have integrated coils, so the complete pod is replaced when the coil wears out. GPP cartridges are compatible across the G3, G4 and G5 series, although resistance and filling style vary. The G5 Lite and G5 Lite SE have a 1600mAh battery, while the G4 Pro has an 1800mAh battery.
Caliburn G and G2 kits
Caliburn G and G2 kits use replaceable coils with compatible refillable pods. This lets users change the coil without replacing the entire pod. The Caliburn G has a 690mAh battery and supports a 0.8Ω coil. The G2 has a 750mAh battery and includes 1.2Ω and 0.8Ω coils.
Caliburn A3 kits
Caliburn A3-family kits use refillable pods with integrated coils. The standard A3 pod has a 1.0Ω mesh coil and a top-fill design. The A3S uses a side-fill pod and supports both its own A3S cartridges and compatible A3 pods. Uwell also lists compatibility across the A3, A3S, AK3 and AZ3 families.
Caliburn A2 kits
Caliburn A2-family kits use refillable pods with integrated coils. The standard A2 pod uses a 0.9Ω coil. The A2S has a 1.2Ω side-fill pod and also supports the 0.9Ω Caliburn A2 pod. The AK2 uses a 0.9Ω A2 pod.
Caliburn replacement pods
Caliburn pods hold up to 2ml of e-liquid. These food-grade replacement pods with built-in coils need to be changed as a complete cartridge when the coil wears out. Available options include different pod types for compatible Caliburn models.
| Product | Resistance |
|---|---|
| Caliburn G3 refillable Pod 0.6ohms meshed | 0.6Ω |
| Caliburn G3 refillable Pod 0.9ohms meshed | 0.9Ω |
| Caliburn A3 refillable pod 1.0 ohms meshed | 1.0Ω |
| Caliburn Pod cartridge 1.4ohms | 1.4Ω |
The G3 and A3 cartridges belong to different pod families. Do not assume that an A3 cartridge fits every A-series device or that an original Caliburn cartridge fits every KOKO model.
Caliburn coils
Some Caliburn devices use replaceable G coils. This allows users to change the coil while keeping a compatible pod. G3-family cartridges, A3 pods, A2 pods and original Caliburn cartridges use different replacement arrangements. Caliburn G coils are available in different resistance options, with prices varying by product and pack size.
- Caliburn G Coil 0.8Ω Meshed costs £10.00 and features a 0.8Ω mesh coil.
- Uwell Caliburn G Replacement Coil costs £11.50 and comes in a pack of four, with 0.8Ω mesh and 1.0Ω standard coil options.
Uwell Caliburn Models Compared
Uwell Caliburn devices come in different pod-system types. The main difference is how each device uses replacement pods or coils. G3/GPP models use compatible GPP cartridges, while older G-series devices use replaceable coils. A-series and original Caliburn models have their own cartridge arrangements.
| Pod-system family | Models | Pod or coil system | Best for |
|---|---|---|---|
| G3/GPP | G3, G3 Pro, G4 and G5 | GPP cartridges with built-in coils | Users who need replacement cartridges for compatible GPP devices |
| G-coil | G, G2, X and GK2 | Separate replacement coils used with compatible pods | Users who want to replace the coil without replacing the complete pod |
| A3 | A3, A3S, AK3 and AZ3 | Refillable pods with built-in coils | Users who need replacement pods for a compatible A3-family device |
| A2 | A2, A2S and AK2 | Refillable pods with built-in coils | Users seeking replacement cartridges for a verified A2-family device |
| Original/KOKO | Original Caliburn and compatible KOKO models | Model-specific refillable cartridges | Owners of older devices who need matching replacement pods |
Pod and coil compatibility depends on the model and cartridge type. Compatibility between models within the same family should not be assumed unless confirmed.
What is the current Uwell Caliburn range?
Uwell's manufacturer product pages list newer G4 and G5 models alongside earlier Caliburn devices. However, the manufacturer's range does not confirm that every model is available from a UK retailer.
What is the difference between Caliburn G2 and G3?
The main difference is the replacement system. The Caliburn G2 uses separate G-series coils, while the G3 belongs to the GPP cartridge platform. GPP cartridges have built-in coils, so the entire cartridge needs replacing when the coil wears out. These cartridges are not compatible with every Caliburn device.
Which Uwell Caliburn model should I choose?
Start with the device you own and identify its exact model. Then check the compatible pod or coil, resistance and product listing. For a new kit, check that matching replacement parts are available before buying. This approach helps you avoid ordering consumables that don't fit the device.
Which Pods and Coils Fit Uwell Caliburn Kits?
Uwell Caliburn pods and coils are designed for specific device families. The G3/GPP platform uses cartridges with built-in coils, while the G, G2, GK2 and X models use compatible replacement G-series coils.
The MHRA's published product list helps consumers check whether a nicotine-containing vaping product has been notified for UK supply, but it does not confirm pod or coil compatibility with a specific Caliburn model.
| Caliburn pod or coil | Resistance | Compatibility | Fit source | Draw style |
|---|---|---|---|---|
| Caliburn G3 refillable pod | 0.6Ω | G3/GPP platform, including compatible G4 and G5 devices | Vapeverse listing and Uwell G Pod Platform | RDL |
| Caliburn G3 refillable pod | 0.9Ω | G3/GPP platform, including compatible G4 and G5 devices | Vapeverse listing and Uwell G Pod Platform | RDL or MTL |
| Caliburn A3 refillable pod | 1.0Ω | Caliburn A3, A3S, AK3 and AZ3. | Uwell A3, A3S and AZ3 | MTL |
| Caliburn Pod cartridge | 1.4Ω | Compatible with the original Caliburn and Caliburn KOKO, but not the KOKO Prime. | Uwell original Caliburn, Uwell KOKO and Caliburn compatibility guide | MTL |
| Uwell Caliburn G replacement coil | 0.8Ω mesh or 1.0Ω standard | Caliburn G, G2, GK2 and X. | Uwell G, G2, GK2, X and Vapeverse listing | 0.8Ω mesh: RDL; 1.0Ω standard: MTL |
What is the difference between MTL and RDL?
MTL vaping involves drawing vapour into the mouth before inhaling it. RDL vaping allows a more open draw with some airflow restriction. The vaping style depends on the cartridge, coil resistance, airflow and device settings. For more information, see MTL vape kits.
Do Caliburn G3 pods fit the G4?
The G4 works with older and upgraded GPP cartridges, while upgraded GPP cartridges also fit the G3 series. However, not all Caliburn pods are compatible with every device.
Are Caliburn pods prefilled?
Caliburn pods are designed to be filled with compatible e-liquid. Some have built-in coils, which means the whole cartridge is replaced when the coil wears out. G-series replacement coils are separate components used with compatible pods.
How long does a Caliburn pod last?
There is no fixed lifespan that applies to every Caliburn pod. Replacement intervals depend on the cartridge design, frequency of use and other operating conditions. Follow Uwell's instructions and replace the pod or coil when required.
Uwell Caliburn Delivery, Warranty, 2ml and 18+ Rules

What warranty covers a Uwell Caliburn kit?
Uwell Caliburn kits have a manufacturer warranty, with the terms and duration depending on the model. Faulty or incorrect items can be reported through the retailer's contact form. The returns policy explains the conditions for faulty devices and consumables, including reporting deadlines for certain faults. Keep the original packaging and proof of purchase when requesting help.
Are Uwell Caliburn pods 2ml in the UK?
Caliburn pods hold 2ml of e-liquid. Under the Tobacco and Related Products Regulations, refillable e-cigarette tanks and relevant cartridges are limited to 2ml. Nicotine-containing refill containers are limited to 10ml, and nicotine concentration cannot exceed 20mg/ml. International versions can have different stated capacities.
Do you need to be 18 to buy a Uwell Caliburn?
Yes, buyers must meet the UK’s minimum age requirement. From 29 October 2026, selling any vaping or nicotine product to someone under 18 will be an offence under the updated UK rules. Retailers selling online must also apply the relevant age-verification requirements. These requirements apply to Uwell Caliburn products and other vape brands.
Uwell Caliburn vs Other Pod Kits by Pod System and Draw
Uwell Caliburn, Vaporesso XROS, OXVA XLIM and VOOPOO ARGUS devices use different pod systems. Compare the cartridge type, coil resistance, airflow and exact model compatibility before choosing a replacement. Similar specifications do not mean that pods from different brands will fit the same device.
Vaporesso XROS: XROS pods use built-in mesh coils and come in different resistance options. COREX 3.0 is Vaporesso's mesh heating technology.
OXVA XLIM: XLIM cartridges are available in 0.4Ω, 0.6Ω, 0.8Ω and 1.2Ω options, depending on the cartridge type. Compatibility varies by model and cartridge version.
VOOPOO ARGUS: The ARGUS range includes model-specific pods and top-fill cartridges. Resistance and capacity vary by cartridge type, so confirm the exact device and UK-compatible version.
Are Vaporesso XROS pods compatible across XROS devices?
Vaporesso describes the XROS range as sharing a pod platform across its devices. However, check the cartridge version, resistance and market-specific capacity before purchasing.
Do Caliburn G3 pods fit OXVA XLIM devices?
No. Caliburn G3 cartridges belong to the G3/GPP platform, while OXVA XLIM devices use XLIM cartridges. The two systems are different, and their pods are not interchangeable.
For Caliburn owners, the key step is to match the replacement pod or coil to the exact device model.
