Uwell Caliburn G4 Pro Pod Vape Kit

Caliburn G4 Pro

The Uwell Caliburn G4 Pro is a 35W pod system with a 2.51 inch touchscreen and 1800mAh battery. Everything works through the touchscreen: wattage, modes, themes, puff counter, and settings. There are no physical buttons apart from the power lock. It is the Pro model in the Caliburn vape kit range, sitting above the standard Caliburn G4 with a bigger 1800mAh battery and the touchscreen. In the UK the Uwell G4 Pro ships as a complete kit. It sits on the GPP pod platform and works with Caliburn GPP pods from 0.4Ω to 1.2Ω covering both RDL and MTL vaping.

You get two GPP pods in the box: a 0.4Ω and a 0.6Ω. Both are top-fill. The kit handles nic salts and 50/50 e-liquids across the full GPP resistance range, and the vape juice flavours for the Caliburn G4 guide covers flavour pairings. Eight colours available, all with an aluminium body and a droplet-shaped e-liquid viewing window on the pod.

Caliburn G4 Pro Themes

The G4 Pro comes with 6 UI themes, each with its own animation that plays while you vape. Three core designs are available out of the box. The remaining themes unlock through Uwell's firmware updates or promotional codes.

Access themes by swiping down on the touchscreen and tapping the theme option. Each theme changes the colour scheme, layout, and animation style on the display. The themes are cosmetic only and don't affect wattage or pod settings.

GPP Pod Compatibility

The Caliburn G4 Pro works with every GPP pod, including the G3 series. PRO-FOCS 4.0 reads the pod resistance and adjusts output to match.

Resistance	Fill Type	Wattage	Style
0.4Ω	Top-fill or side-fill	18-25W	RDL
0.6Ω	Top-fill or side-fill	15-22W	RDL
0.8Ω	Side-fill	12-18W	MTL
1.0Ω	Side-fill	10-15W	MTL
1.2Ω	Side-fill	8-12W	Tight MTL

The 0.4Ω and 0.6Ω come in both top-fill and side-fill versions. The 0.8Ω and above are side-fills only. All GPP pods hold 2ml (UK TPD). The full Caliburn pods range is available separately.

Stepless Airflow

Rotate the ring at the base of the pod to adjust the draw. There are no fixed click stops so you can fine-tune it anywhere from fully closed (tight MTL) to fully open (loose RDL). The airflow setting stays where you leave it.
