Uwell Caliburn G4 Pro Koko Pod Vape Kit

Description - Uwell Caliburn G4 Pro Koko Pod Vape Kit

The Uwell Caliburn G4 Pro Koko is the first device in the Koko range to feature a full 2.0-inch shatterproof touchscreen, and it marks a meaningful upgrade over its predecessors. A 2000mAh internal battery paired with adjustable 1-35W output gives you all-day power in a compact, square form factor. Stepless airflow covers everything from a tight mouth-to-lung draw to a relaxed restricted direct-lung style, and compatibility with the full Caliburn GPP pod range means you can tailor the resistance to suit exactly how you vape. Whether you're switching from cigarettes, upgrading from an older Caliburn, or just want a capable daily carry without the bulk, this kit delivers it. UK stock is held and ready for fast dispatch.

Introducing the Uwell Caliburn G4 Pro Koko

Few compact pod kits offer this level of control without complicating the experience. The G4 Pro Koko manages it by putting everything through a responsive 2.0-inch touchscreen, so wattage adjustments, output mode changes and settings access all happen in a single tap rather than through multi-button sequences. The aluminium alloy body keeps the device sturdy without adding unnecessary weight, and the U² anti-leak refill system means topping up the pod is clean and straightforward.

Uwell's Pro-FOCS 4.0 flavour technology is built directly into the GPP pod coils. It works by regulating temperature and wattage delivery to maintain consistent flavour across the life of the pod, and Uwell's own specification cites an improvement in both flavour satisfaction and pod longevity over earlier versions. The practical result is that flavour stays accurate from the first puff on a new pod to the last.

If you want a pod kit that gives you genuine control without adding bulk or complexity, the Caliburn G4 Pro Koko delivers it.

Why Choose the Uwell Caliburn G4 Pro Koko?

• Device type: Compact square pod kit with draw-activated firing and a 2.0-inch shatterproof touchscreen
• Battery and power: 2000mAh internal battery with adjustable 1-35W output and USB-C fast charging at 5V/2.5A
• Output modes: Three modes tuned to different vaping styles. Storm gives a punchier, more immediate hit suited to the 0.4 ohm pod. Waves delivers smooth, consistent output across the draw, making it the better choice for all-day use. Custom lets you build a manual power curve, adjusting how output ramps up and sustains through each puff
• Airflow: Stepless slider moves from tight MTL (mouth-to-lung, which mirrors the draw resistance of a cigarette) to a looser RDL (restricted direct-lung) style
• Flavour technology: Pro-FOCS 4.0 optimises temperature and wattage delivery for consistent taste and extended pod life
• Build: Aluminium alloy body with a PCTG pod and IML finish. Available in eight colours: Desert Gold, Waves Black, Cosmic Grey, Mirror Silver, Crystal White, Light Green, Glass Blue and Coral Pink
• Personalisation: Five collectible UI themes that unlock progressively with puff milestones, keyboard input to rename your device, eight language options, adjustable screen brightness and an animation toggle
• Compliance: 2ml TPD-compliant pod capacity for UK use
• Best for: Switchers moving from cigarettes or disposables, everyday vapers wanting a reliable all-day carry, and anyone upgrading from an older Caliburn model

Few pod kits at this price point combine a touchscreen interface, three distinct output modes and a 2000mAh battery in a device small enough to fit in a jacket pocket.

Compatibility and Performance

Understanding which pod suits your style makes a real difference to how this device performs. The G4 Pro Koko uses Caliburn GPP cartridges, which are cross-compatible with G3 and G4 series devices. If you already own another Caliburn from either of those ranges, your existing spare pods will fit without any adapters or modifications. The GPP range covers four resistance options, and the kit ships with a 0.4 ohm and a 0.6 ohm pod included.

Resistance guide:

• 0.4 ohm: RDL vaping, warmer vapour. Best matched to 50/50 freebase at 6-12mg or nic salts at 10-20mg
• 0.6 ohm: MTL to light RDL, balanced flavour. Suits nic salts at 10-20mg or 50/50 freebase at 6-12mg
• 0.9 ohm and 1.2 ohm: Tight MTL draw, closest to a cigarette-style inhale. Best matched to nic salts at 10-20mg (20mg is the UK legal maximum for nicotine-containing e-liquid under TPD regulations)

This device works with nic salts and 50/50 freebase blends, or VG-forward mixes up to roughly 60/40. High-VG shortfills designed for sub-ohm kits are not suitable here as they won't wick properly through the GPP pods. The vapour output is clean and flavour-forward rather than cloud-heavy, which suits vapers who prioritise taste and satisfaction.

Charging runs via USB-C at up to 5V/2.5A with fast charge support. A USB-C cable is not included by the manufacturer, so check your package contents on arrival and use a suitable cable and power source rated at 5V.

Because the GPP pod platform spans four resistance options and is shared across the G3 and G4 series, spare pods are straightforward to source and interchangeable if you already own another Caliburn device.

Uwell Caliburn G4 Pro Koko Highlights

The G4 Pro Koko brings together hardware that punches well above its size class. Here is what sets it apart:

• 2000mAh battery for full-day use, with fast USB-C top-up when you need it
• 2.0-inch shatterproof touchscreen for one-tap control over modes, wattage and settings
• Three output modes (Storm, Waves, Custom) matched to different draw styles and coil resistances
• Stepless airflow to tune your inhale from tight MTL to relaxed RDL without any tools
• Pro-FOCS 4.0 flavour technology for consistent taste and longer-lasting pod performance
• U² anti-leak design keeps refills clean and the device dry
• Five collectible UI themes that unlock progressively as your puff count hits set milestones

Together, these features mean the G4 Pro Koko works just as well on day one out of the box as it does after months of regular use.
