The Uwell Caliburn series has become a benchmark for pod devices, and the Caliburn G4 takes this a step further. It offers advanced controls, a stronger battery, quality build, and exceptional flavour. At Vegas Vapor, we’ve tested this device in real-life scenarios to provide a complete review. Whether you are a beginner or upgrading from an older pod system, this review will give you all the insights you need.
Design and Build Quality
From the moment you hold the Caliburn G4, you notice its refined design. It has an aluminium alloy chassis that feels sturdy yet lightweight. The finish is smooth, and rounded edges make it comfortable to hold.
The device weighs around 54.7 grams, which is competitive for modern pod systems. The front features a colour screen (0.85″) with multiple themes, day/night mode, and brightness control, adding a premium look.
Filling the pod is convenient. The GPP pods (compatible with older G3 pods) allow side filling without removing the pod. Airflow is adjustable with a slider, and the pod can be oriented in two ways to control the draw.
Some minor drawbacks exist. The aluminium finish can feel greasy from fingerprints. The pod window, used to monitor e-liquid, may be hard to see in bright light.
Vegas Vapor insight: The Caliburn G4 combines style, comfort, and practicality, with only minor ergonomic trade-offs.
Key Features and Specifications
The Caliburn G4 comes with several features that make it stand out:
- Battery: 1300 mAh built-in
- Maximum Output: Up to 35 Watts
- Display: 0.85″ full-colour screen with multiple UI themes
- Modes: Two output modes – “Wave” and “Storm”
- Pod Compatibility: GPP pods and backward compatible with G3 pods
- Pod Capacity: 2 mL or 3 mL e-liquid depending on the variant
- Airflow: Adjustable via side slider and reversible pod orientation

Performance: Flavour and Vapour
Flavour and vapour production are major strengths of the Caliburn G4. GPP pods and older G3 pods deliver excellent flavour. The Uwell Pro‑FOCS 4.0 flavour technology enhances taste and consistency.
A 0.9 Ω pod provides a smooth mouth-to-lung experience, while a 0.6 Ω pod offers restricted direct-lung vaping. Some tests showed the 0.9 Ω pod could handle over 20 mL of juice without flavour loss. The draw remains clean and consistent.
The 0.9 Ω pod is limited to 15 W, so this device is not ideal for high-wattage or large cloud production. For everyday flavour vaping, it is an excellent choice, offering a balance of taste, vapour, and convenience.
Battery Life and Charging
The 1300 mAh built-in battery offers decent performance. Real-world usage shows moderate use lasting most of a day. Heavy use may require more frequent charging.
USB-C fast charging allows for quick turnaround, typically under an hour to full charge. To prolong battery life, avoid deep discharges, use appropriate wattage for your pod, and keep airflow moderate.
User Experience and Usability
The Caliburn G4 is simple to use, though advanced features may require a slight learning curve.
- Power On/Off: Five clicks of the fire button
- Menu/Mode Access: Long press or multiple clicks
- Pod Refill: Side-fill design
- Airflow Adjustment: Slider and pod orientation
The colour screen provides useful feedback such as battery level, puff count, wattage, and resistance. Maintenance is simple: replace pods when flavour declines, clean the device, and refill before dry hits. Compatibility with G3/GPP pods adds extra value.
