Caliburn G4 Pro

The Uwell Caliburn G4 Pro is a 35W pod kit with a 2.51 inch touchscreen and 1800mAh battery. Everything runs through the touchscreen: wattage, modes, themes, puff counter, and settings. There are no physical buttons apart from the power lock. 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. Eight colours available, all with an aluminium body and a droplet-shaped e-liquid viewing window on the pod.

Touchscreen and Settings

The 2.51 inch screen responds in under 0.2 seconds. Tap to change wattage between 5W and 35W. Swipe down to open the full settings menu.

Custom power mode lets you set different wattage for three stages of each puff: start, middle, and end. The kit follows that curve on every draw. Standard mode holds constant wattage throughout.

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.

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 GPP 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.

Caliburn G4 Pro Colours

All eight use an aluminium shell. The metallic and patterned finishes have a slightly different texture to the solid colours.

Why Choose the Caliburn G4 Pro

The G4 Pro is the only Caliburn with a full 2.51 inch touchscreen and custom power curves. Every other kit in the series uses a smaller screen or button controls. The 1800mAh battery is the biggest in the Caliburn range too, nearly double the standard G4's 1000mAh.

It also sits on the GPP pod platform, so you're not locked into one or two pod options. Every GPP pod from 0.4Ω to 1.2Ω works, including the older G3 pods. That's RDL and MTL from the same kit with one airflow ring to switch between them. If you already own GPP pods from another Caliburn, they'll slot straight in.
