Which Uwell Caliburn Vape Kit Should You Choose?
Your choice comes down to how you plan to use and carry the kit, and whether you prefer buttons or touchscreen controls.
Caliburn G3 Pro for a Full-Front Display
Featuring a large front display and a slim, ergonomic design, the Uwell Caliburn G3 Pro Pod Kit balances convenience with functionality. The screen keeps important settings visible, making quick adjustments simple. It also provides more control than entry-level pod kits, making it a great choice for users looking to upgrade without switching to a touchscreen device.
Caliburn G4 for Slim Everyday Use
The Uwell Caliburn G4 Pod Kit keeps the slim pen-style design that many vapers prefer. Its lightweight body is easy to carry in your pocket or bag, making it ideal for everyday use. A bright colour screen keeps key settings easy to view, while the adjustable airflow slider lets you fine-tune your draw. It offers more control than basic pod kits without the larger size or touchscreen interface of the G4 Pro KOKO.
Caliburn G4 Pro KOKO for Touchscreen Control
The Uwell Caliburn G4 Pro KOKO Pod Vape Kit stands out with its responsive touchscreen, making it quick and easy to adjust your settings. Its compact square design offers a different feel from traditional pen-style devices, while the built-in 2,000mAh battery provides longer use between charges. Combining touchscreen controls with a high-capacity battery, it offers one of the most feature-rich options in the Caliburn range.
Compatible Uwell Caliburn Pods
Caliburn devices do not all use the same pods. Match the replacement cartridge to your exact device before ordering. Browse the full Uwell Caliburn Pods range to compare available resistances and filling methods.
| Device family | Suitable replacement | What to check |
|---|---|---|
| Caliburn G3 and G4 series | Caliburn GPP cartridges | Resistance, fill design and stated device support |
| Caliburn A2, A2S and AK2 | A2-compatible cartridges | Model name and coil resistance |
| Original Caliburn G and KOKO Prime | Caliburn G cartridges | Whether a separate coil is required |
Replacements for Caliburn A2 Devices
Designed for Caliburn A2 devices, Uwell Caliburn A2 Replacement Pods provide a direct replacement when it's time for a new pod. They are only compatible with supported A2-series kits and cannot be used with Caliburn G3 or G4 devices.
Before ordering, check that your vape kit is listed as compatible and choose the resistance that best matches your preferred vaping style.
Options for the Original Caliburn G Range
Uwell Caliburn G Replacement Pods are made for compatible devices, including the original Caliburn G and Caliburn KOKO Prime. Unlike newer Caliburn pods with built-in coils, these pods use replaceable coils. This lets you change the coil without replacing the entire pod.
While you order, check whether you need an empty pod, a replacement coil, or both to keep your device ready to use.
How Resistance Affects the Draw
Resistance changes how the vape feels and the amount of power it requires:
- Higher resistance works at lower wattages and provides a tighter draw. It is a popular choice for mouth-to-lung (MTL) vaping.
- Lower resistance requires more power and delivers a warmer, more open draw with increased vapour production.
- Always check the recommended wattage and use the cartridge within its suggested power range for the best performance.
Make sure the cartridge is compatible with your vape kit before purchasing or using it.
The lowest resistance isn't always the best option. Your preferred draw, e-liquid, and device all play a part in selecting the right cartridge.
