Clear Display with Simple, Everyday Control

The Caliburn G4 features a 0.85″ HD color screen that provides clear visibility of battery life, puff count, and vaping mode. With both day and night display settings, it remains easy to read in different lighting conditions. A single multi-function button allows you to power the device on or off, adjust settings, and switch modes with straightforward, intuitive control.

Two Output Modes for Different Vaping Styles

The Uwell Caliburn G4 offers two output modes to match your preferred vaping experience. Storm Mode delivers a stronger, warmer vape with increased vapor production, while Waves Mode provides a smoother, more consistent draw for everyday use. This flexibility allows you to easily adjust performance without complex settings.

Compatible Pods with Leak-Resistant Design

The Caliburn G4 is compatible with both Caliburn GPP cartridges and previous G3 pods, making replacements simple and accessible. The side-fill design allows you to refill without removing the pod, while Uwell’s U² technology—combining ultrasonic welding and a U-shaped airflow channel—helps reduce leaking and improve overall performance.
