UWELL Caliburn G4 Kit

The Uwell Caliburn G4 Kit is a lightweight vape kit that combines a draw‑activated firing system with an adjustable airflow switch, making it suitable for users who value simplicity and precise control over their vaping experience. The device uses the brand’s proprietary GPP Pod Cartridges, which are refillable to a 3 mL capacity through a convenient side‑filling system, and delivers up to 35 W of power from its built‑in battery.

Heating System

The Caliburn G4 employs a draw‑activated firing mechanism that relies on dual sensors to detect airflow. When the user inhales, the sensors trigger the heating element, which then draws power from the internal 1800 mAh battery to produce vapor. Because the system is activated by inhalation rather than a button press, the device offers a more natural draw and reduces accidental activation. The heating element operates within the maximum output of 35 W, ensuring consistent vapor production across a range of e‑liquid viscosities.

Airflow Control

An adjustable airflow switch is integrated into the device’s chassis, allowing users to fine‑tune the resistance and flavor intensity. By moving the switch, the user can increase or decrease the amount of air that mixes with the vapor before it reaches the mouthpiece. A tighter setting results in a cooler, more concentrated hit, while a looser setting produces a warmer, smoother vapor stream. This feature is especially useful for those who prefer to customize their vaping experience based on personal taste or the type of e‑liquid used.

Battery

The Caliburn G4 houses a rechargeable 1800 mAh battery that powers both the heating element and the device’s internal electronics, including the display. The capacity is sufficient to provide several hours of use between charges while maintaining a slim profile that fits comfortably in hand or pocket. Because the battery is integrated into an aluminum alloy chassis, it benefits from improved heat dissipation and structural integrity during extended vaping sessions.

POD Chamber

The GPP Pod is magnetically attached to the Caliburn G4 body, simplifying assembly and disassembly. Each pod holds up to 3 mL of e‑liquid and can be refilled via a side‑filling system that eliminates the need for removing the pod from the device. The magnetic connection ensures a secure fit during use while allowing quick replacement when the pod is empty or needs cleaning.

Display Screen

The device features a 0.85 inch color display screen mounted on the aluminum alloy chassis. This screen provides real‑time feedback on battery level, wattage output, and other operational parameters, allowing users to monitor performance without needing external devices. The compact size of the display keeps the overall footprint minimal while still offering clear visibility during use.
