Uwell Caliburn G4 — Full Review & Specs
The Uwell Caliburn G4 is the fourth generation of Uwell’s best-selling Caliburn G pod kit series. It features PRO-FOCS 4.0 flavour technology, a 1300mAh battery, up to 35W output and Uwell’s new GPP (G-Power Platform) pod system. The G4 introduces two intelligent power modes — Storm and Waves — for a more tailored vaping experience. Available at Galaxy Vape Darlington.
Is the Uwell Caliburn G4 Any Good?
Yes — the Caliburn series has been a consistent best-seller in the UK since the original Caliburn launched, and the G4 is the most feature-rich version yet. PRO-FOCS 4.0 (Uwell’s flavour optimisation system) combined with the new GPP pod design delivers noticeably improved flavour clarity compared to previous Caliburn G models. The addition of Storm and Waves modes gives vapers genuine control over how each puff feels.

Uwell Caliburn G4 FAQ
What is the difference between Storm and Waves modes on the Caliburn G4?
Storm mode boosts the power output at the beginning of each puff, delivering a stronger, more immediate throat hit. Waves mode uses a smooth oscillating power curve throughout the puff, producing a consistent, even flavour from start to finish. Storm suits vapers who prefer a punchy hit; Waves suits those who prefer a smoother draw.
What pods does the Uwell Caliburn G4 use?
The Caliburn G4 uses Uwell GPP (G-Power Platform) pods. These are purpose-designed for the G4 platform and are available in multiple resistances. The 0.8 ohm GPP pod is best suited to nicotine salt e-liquids and MTL vaping at 10mg or 20mg.
What is PRO-FOCS 4.0?
PRO-FOCS 4.0 is Uwell’s fourth-generation Flavour Optimisation and Consistency System. It uses intelligent power regulation to maintain optimal temperature and vapour production throughout each puff, resulting in more accurate and consistent flavour reproduction compared to earlier Caliburn G models.
How does the Caliburn G4 compare to the Caliburn G3?
The Caliburn G4 upgrades to the GPP pod platform, adds Storm and Waves intelligent power modes, and introduces PRO-FOCS 4.0. These combine to deliver better flavour consistency and more user control than the G3. The G4 also has a clearer 0.85-inch display showing more operating data.
What e-liquid should I use with the Caliburn G4?
50/50 VG/PG nicotine salt e-liquids at 10mg or 20mg are ideal with the 0.8 ohm GPP pod. Elux Legend, Bar Juice 5000 and Crystal Clear are all popular choices that pair well with the G4’s flavour technology. All are available from £3.00 at Galaxy Vape.
