Uwell Caliburn G4 Pro — Full Review & Specs

The Uwell Caliburn G4 Pro is the most advanced pod kit in Uwell’s Caliburn G line — and the first Caliburn to feature a touchscreen. Its headline feature is Custom Mode, which lets vapers independently adjust power at the Start, Middle and End stages of each puff for a fully personalised vaping experience. It uses the same GPP (G-Power Platform) pod system as the Caliburn G4 and is available in Pearl Silver, Classic Silver and Cosmic Gray. Available at Galaxy Vape Darlington.

What Makes the Caliburn G4 Pro Different?

The Caliburn G4 Pro represents a significant step forward for the Caliburn series. Where the G4 offers pre-set Storm and Waves modes, the G4 Pro lets you build your own power curve. Custom Mode gives independent control of the Start, Middle and End power levels — meaning you can tune the warmth, vapour density and throat hit at every stage of the draw. The touchscreen interface makes navigating these settings far more intuitive than button-based menus on previous Caliburn models.

Key Features of the Caliburn G4 Pro

• Touchscreen Display — The first touchscreen interface in the Caliburn range, replacing the traditional button/LED system
• Custom Mode — Independently adjust Start, Middle and End wattage for a personalised power curve on every puff
• GPP Pods — G-Power Platform pods compatible with both the G4 and G4 Pro, in 0.8Ω and additional resistance options
• PRO-FOCS Technology — Uwell’s flavour optimisation system ensures consistent, accurate flavour throughout pod life
• Dual Activation — Auto-draw and touchscreen fire for flexible use
• 3 Colourways — Pearl Silver, Classic Silver and Cosmic Gray — understated, premium finishes
• USB-C Charging — Fast and universal USB-C charging
• Shared GPP Pod Compatibility — GPP pods are shared with the standard Caliburn G4 for easy replacement sourcing

What Is Custom Mode and How Do You Use It?

Custom Mode is the defining feature of the Caliburn G4 Pro. It divides each puff into three phases — Start, Middle and End — and allows you to set a different wattage for each. For example, you might set a higher Start wattage for an immediate hit, a lower Middle wattage for a smooth mid-puff, and a slightly elevated End wattage to finish the draw with warmth. Using the touchscreen, you simply swipe to each phase and tap to adjust. This level of control was previously only available on box mods costing significantly more.

What E-Liquid Works Best with the Caliburn G4 Pro?

The 0.8Ω GPP pod is ideal for 50/50 nic salt e-liquids at 10mg or 20mg, making the G4 Pro particularly well-suited to premium nic salts where you can appreciate the Custom Mode flavour tuning. Recommended e-liquids at Galaxy Vape:
