35W • 1400mAh • GPP POD
Uwell Caliburn G4 Classic
A 35W pod device combining the classic Caliburn design with a powerful battery, twin sensors, dynamic RGB lighting, and an advanced GPP pod system.
Uwell Caliburn G4 Classic 35W Pod System is a compact pod mod device that enhances the classic and user-friendly experience of the Caliburn series with modern technologies. Featuring a 1400mAh built-in battery and a 35W maximum power output, it delivers a robust performance for daily vaping.
Crafted from aerospace-grade TX aluminum alloy, its chassis combines durability and ergonomics with fine CNC machining details and sleek design lines. Thanks to the transparent e-liquid window, the remaining juice level can be easily monitored.
1400mAh Battery and 35W Performance
The Caliburn G4 Classic features a 1400mAh high-density built-in battery designed for extended usage. The maximum 35W output power adapts seamlessly to various pod resistances, ranging from lower-wattage MTL vaping to airier RDL draws.
Recharged via a USB Type-C port, the actual runtime may vary depending on pod resistance, puff duration, wattage settings, and frequency of use.

Top-Filling and E-Liquid Monitoring
Thanks to the top-filling system of the GPP pod, e-liquid can be refilled without removing the pod from the device. The transparent viewing window allows direct monitoring of the remaining juice level.
- Carefully open the top-fill cap on the pod.
- Add e-liquid into the fill port, avoiding the central airflow tube.
- Ensure the fill cap is completely closed.
- Wait approximately 10 minutes after filling a new pod for the first time.
- Do not fire the device when the pod is empty.
