Caliburn G4 Pro Kit

Uwell Caliburn G4 Pro kit - Taste above everything.

Building on the upgraded CALIBURN GPP cartridges and the advanced PRO-FOCS 4.0 flavour technology, CALIBURN G4 delivers a 35% increase in both cartridge lifespan and flavour satisfaction, and much more besides.

And most importantly, we’ve created two vaping modes for CALIBURN G4: Storm Mode and Waves Mode, taking your vaping experience to the next level. 

Airflow control, tailored to your preference.

CALIBURN G4 offers multiple simple yet precise ways to adjust airflow, ensuring a tailored experience that exceeds your wildest expectations. 

Vaping has never been this fun.

While enjoying your vaping journey, don’t miss out on the fun: CALIBURN’s carefully designed theme UI. And this time, it is proudly displayed on a thumb-sized 0.85″ HD colour screen. 

Geared up for compatibility.

CALIBURN GPP cartridges compatible.

CALIBURN G4 is fully compatible with both previous and upgraded CALIBURN GPP cartridges. The upgraded cartridges are also compatible with the CALIBURN G3 series devices. You don’t even need to remove the upgraded GPP cartridge when refilling.

The upgraded GPP cartridges also feature an improved ergonomic design, perfectly contoured to your mouth for an even more comfortable vaping experience. 

Strive towards excellence.

Every drop stays where it should be.

We have never ceased our relentless pursuit of professional excellence in CALIBURN GPP cartridges. UWELL’s U² technique, also known as Ultrasonic Welding and U-shaped Channel Design, significantly enhances the leak-resistant performance of the CALIBURN GPP cartridges, delivering a spectacular vaping experience.
