The Uwell Caliburn G4 Pro Pod Kit is a refillable touchscreen vape kit built for UK users who want longer battery life, adjustable performance and full control over their draw. Powered by a large 1800mAh built-in battery with adjustable output up to 35W, this refillable pod vape kit supports both MTL (mouth-to-lung) and restricted direct-to-lung vaping across the full GPP pod range.
Compatible with 0.4Ω to 1.2Ω CALIBURN GPP pods, the G4 Pro performs exceptionally well with 10mg and 20mg nicotine salts as well as standard 50/50 freebase e-liquids. Whether you are upgrading from the Caliburn G3, moving away from disposables, or choosing your first refillable pod kit, this device offers stronger battery endurance, touchscreen precision and airflow flexibility in a compact aluminium design.

Battery & Charging Performance
The integrated 1800mAh battery delivers reliable all-day performance for most mouth-to-lung users. Designed as a long battery pod kit for everyday use, it maintains stable power output across the charge cycle for consistent flavour. USB-C fast charging ensures reduced downtime between sessions.
1800mAh Battery
The powerful 1800mAh rechargeable battery delivers all-day vaping with consistent power output.
This battery capacity makes the G4 Pro especially suitable for regular nicotine salt users who want dependable daily performance without carrying spare devices.
Touchscreen Interface & Customisation
The 2.51-inch touchscreen replaces traditional button combinations and allows fast, intuitive control. Adjust wattage, switch between modes and access settings using simple swipe gestures. The responsive display improves usability while keeping the device compact and pocket-friendly.
Engaging UI Themes
The innovative touchscreen vape interface features 6 customisable themes for personalised vaping experiences.
Multiple interface themes, brightness control and custom display settings allow users to personalise their device without adding complexity to daily use.
Power Control, Output Modes & Airflow
Adjust output between 5W and 35W depending on your installed pod resistance. Lower resistance pods (0.4Ω–0.6Ω) support restricted direct-lung vaping, while higher resistances (0.8Ω–1.2Ω) are ideal for tight MTL draws with nicotine salts.
Switching Output Modes
Easy output mode switching via the Smart Settings Hub accessed through simple swipe gestures.
The stepless airflow slider further refines your inhale, allowing precise control from a cigarette-style draw to a looser restricted airflow. This flexibility makes the G4 Pro suitable for both new switchers and experienced pod users.
GPP Pod Platform & Longevity
The Caliburn G4 Pro works with all CALIBURN GPP pods available in our refillable pod collection. Pods typically last between one and two weeks depending on usage and liquid type. For optimal lifespan, prime the pod before first use and avoid heavily sweetened high-VG liquids.
E-Liquid Pairing Guide
This device is optimised for 50/50 VG/PG e-liquids. If you are switching from smoking, 20mg nicotine salts are commonly preferred for stronger nicotine satisfaction, while lighter smokers often choose 10mg. You can learn more in our guide: What Is Nicotine Salt E-Liquid?
