The Uwell Caliburn G4 Vape Kit is a compact pod vape kit made for both MTL (mouth-to-lung) and RDTL (restricted direct-to-lung) vaping. It features a 1300mAh built-in battery, up to 35W output, adjustable airflow, and a slim design that makes daily vaping simple and practical.
The Uwell Caliburn G4 device also works with Uwell Caliburn GPP Pods, giving you more flexibility to match your preferred vaping style. With refillable pods and built-in mesh coils, it is designed to deliver strong flavour, smooth vapour, and easy upkeep without separate coil changes.
If you want a reliable vape kit that feels easy to use but still offers more control over airflow and performance, the Uwell Caliburn G4 is a strong choice for everyday vaping.

The Uwell Caliburn G4 kit offers more control than a basic starter vape, but it stays simple to use. You get fast setup, reliable flavour, and flexible pod options in one pocket-friendly device.
The Uwell Caliburn G4 pod kit has the following key benefits:
This balance of convenience and control is why many users search for the Uwell Caliburn G4 pod vape kit instead of a simpler disposable-style device.
The Uwell Caliburn G4 pod system performs well because it gives you three things many vapers want: strong flavour, flexible draw control, and simple operation.
The 1300mAh battery is large for a compact pod vape. It suits all-day moderate use better than many smaller pod kits. That makes the Uwell Caliburn G4 vape practical for work, commuting, and travel.

The device can output 5W to 35W. Lower wattage suits tighter MTL vaping and higher-resistance pods. Higher wattage suits lower-resistance pods and a warmer, denser RDTL vape.

The airflow adjustment helps you tailor the inhale to your preference. A tighter airflow creates a more restricted cigarette-style MTL draw, while a looser airflow produces a smoother and airier RDTL vape.

The pods use integrated mesh coils, so you replace the full pod once the coil reaches the end of its lifespan. This design reduces coil changes, keeps maintenance simple, and supports consistent flavour.

The Uwell Caliburn G4 pod vape is commonly described as compatible with Caliburn G3 pods and selected Caliburn GPP pods, depending on resistance option and retailer listing.
The Uwell Caliburn G4 is compatible with the following commonly referenced pod options:
| Pod type | Resistance | Typical use |
|---|---|---|
| Caliburn G3 Pod | 0.4ohm | Warmer RDTL vape |
| Caliburn G3 Pod | 0.6ohm | RDTL / looser MTL |
| Caliburn G3 Pod | 0.8ohm | Balanced MTL |
| Caliburn G3 Pod | 0.9ohm | MTL |
| Caliburn G3 Pod | 1.0ohm | Tighter MTL |
| Caliburn GPP Pod | 0.4ohm | Higher-power RDTL |
| Caliburn GPP Pod | 0.6ohm | RDTL |
| Caliburn GPP Pod | 0.9ohm | MTL |
| Caliburn GPP Pod | 1.2ohm | Tight MTL |
Compatibility can vary by stock version and regional packaging. Check the retailer’s pod list before purchase. E-liquid choice matters just as much, which is covered next.
The best e-liquid depends on the pod resistance you use.
The Uwell Caliburn G4 works best with different e-liquids depending on the pod you choose:
| Pod resistance | Best e-liquid type | Vaping style |
|---|---|---|
| 0.4ohm | High VG or lower-nicotine e-liquid, where supported by the pod rating | RDTL |
| 0.6ohm | 50/50 e-liquid or nicotine salt, depending on preference | RDTL / loose MTL |
| 0.8ohm | 50/50 e-liquid or nic salt | MTL |
| 0.9ohm | 50/50 e-liquid or nic salt | MTL |
| 1.0ohm / 1.2ohm | Nic salt or 50/50 freebase e-liquid | Tight MTL |
