The Caliburn G4 refines the classic Caliburn formula with modern controls and improved pod engineering. It pairs a 1300 mAh internal battery with up to 35 W output, button and draw activation, and USB‑C fast charging (2 A), so the device is ready quickly and holds enough charge for a day of moderate use. A bright 0.85‑inch colour display shows power, puff count, theme options and battery status, letting you tune the experience without complexity.

Key features

• Battery & charging: 1300 mAh built‑in battery with fast USB‑C charging for quick top‑ups.

• Power & modes: Adjustable wattage up to 35 W and two distinct output modes (often labelled Storm and Wave) to change the character of each puff.

• Interface: 0.85" colour screen with simple menus, theme options and adjustable brightness for day/night use.

• Activation & airflow: Both button and inhale activation are supported; airflow is adjustable via a side slider, and pods can be flipped to alter draw tightness.

• Pod system: Uses Uwell’s GPP pod family (backwards compatible with many G3 pods) and benefits from improved leak resistance through ultrasonic welding and a U‑shaped channel design.

• Included coils/pods: Kits commonly ship with a 0.4 Ω mesh and a 0.9 Ω mesh pod to cover RDTL and MTL preferences.
