Uwell Caliburn G4 Pro Koko Vape Kit

The Uwell Caliburn G4 Pro Koko combines the reliability of the beloved Caliburn series with cutting-edge touchscreen functionality. It's the first Koko pod kit to feature smart touch controls, but automatically locks during use so you're not accidentally changing your settings whilst vaping. 

With its substantial 2000mAh battery, 35W maximum output, and compatibility with both existing and new Caliburn G3 cartridges, this device bridges the gap between simplicity and sophistication. Whether you're transitioning from smoking or you're an experienced vaper seeking something genuinely innovative, the G4 Pro Koko delivers performance that's both accessible and advanced.

Note: This device does NOT come with a USB-C charging cable, which may need to be purchased separately.

Advanced Touchscreen Technology

The G4 Pro Koko features the first proper touchscreen interface in the Caliburn Koko lineup. The display isn't just for show; it's both functional and responsive, allowing you to navigate through five distinct UI themes that make your experience more engaging. Each theme offers a different visual personality, from minimalist designs to more dynamic interfaces that react to your vaping patterns.

The touchscreen responds well - you can adjust wattage settings directly through the interface, switch between vaping modes, and monitor your battery life with kust a look. The screen brightness automatically adjusts to ambient lighting conditions, which is a thoughtful touch that prevents eye strain during evening sessions.

Exceptional Battery Performance and Charging

The 2000mAh internal battery is really impressive for a device of this size. In real-world usage, you're looking at approximately 1.5 to 2 days of moderate vaping before needing to reach for a USB Type-C cable. Heavy users might find themselves charging daily, but that's still excellent performance considering the 35W maximum output capability.

Charging speed is respectable, taking roughly 90 minutes to reach full capacity from completely depleted. The Type-C port feels solid and well-positioned, though the cable isn't the longest you'll encounter.

Versatile Pod System and Compatibility

The G4 Pro Koko maintains backwards compatibility with previous Caliburn G3 pod cartridges whilst introducing upgraded options specifically designed for this device. The 2ml refillable pod meets UK TPD regulations perfectly, and the top-filling mechanism remains straightforward and leak-resistant when done properly.

Pod installation produces a satisfying click that confirms proper seating. The magnetic connection feels secure without being overly tight, making pod swaps quick and effortless. Airflow adjustment happens automatically based on the installed pod type, though you can fine-tune settings through the touchscreen interface for a more personalised experienced, if you wish to.

Smart Vaping Modes and Performance

The device automatically detects your preferred vaping style and adjusts accordingly, supporting both MTL (mouth-to-lung) and RDTL (restricted direct-to-lung) techniques effectively. The 35W maximum output provides ample power for most vaping preferences, delivering consistent vapour production and flavour intensity throughout.

Smart mode learns from your usage patterns and optimises power delivery accordingly, although manual wattage adjustment remains available for those who prefer complete control over their vaping parameters.

Build Quality and Design Considerations

The G4 Pro Koko feels substantial in hand without becoming cumbersome. The device dimensions make it comfortable for extended holding, and the weight distribution feels balanced.

Materials feel premium, though the glossy finish attracts fingerprints rather enthusiastically. The colour options are tasteful, leaning towards understated elegance rather than flashy aesthetics. Button placement is logical, and the overall ergonomics work well for both left and right-handed users.
