The Uwell Caliburn G4 builds on the strengths of Uwells popular Caliburn series with a host of refinements aimed at delivering a more customisable and satisfying vape. With its high-capacity 1300mAh battery, top-fill G3 pods, 35W max output and a sharp new OLED display, the Caliburn G4 is designed for vapers who want more control and a more immersive experience from their pod kit.

This pocket-friendly device offers two distinct output modes: Storm Mode for increased power and vapour, and Waves Mode for a smoother, more consistent draw. A convenient side-slider airflow adjustment allows you to fine-tune your inhale between tighter MTL and looser RDL styles, depending on your coil preference. The 0.85" display clearly shows your battery life, wattage, puff count and other key info, while the all-in-one smart fire button controls power, output mode, and screen options with a few simple clicks.

Compatible with Uwells G3 and GPP pod series, the Caliburn G4 includes two integrated mesh coil pods (0.4ohm and 0.9ohm), both with a comfortable mouthpiece and easy top-fill design. Together with Uwells PRO-FOCS 4.0 flavour tech, the G4 delivers improved flavour performance and longer pod lifespan for a more satisfying vape.

We Recommend using the following E-Liquid with these pods:

0.4ohm - Use High VG (sub-ohm) E-Liquids
0.9ohm - Use Nic salt or 50/50 (freebase) E-Liquids

Please Note: When filling your pod with e-liquid for the first time, allow the pod to sit for ten minutes before use. This will allow the e-liquid to better saturate the wicking material, a type of cotton, to prevent dry hits and ensure the best flavour and performance from your coil.
