UWELL unveils CALIBURN G4 Classic, marking 10 years of innovation
August 20, 2025
UWELL has introduced the CALIBURN G4 Classic, the latest generation of its flagship pod system, designed to blend advanced technology with precision craftsmanship. The launch celebrates the company’s decade-long presence in the global vaping industry and its ongoing reputation for innovation.
Crafted from aerospace-grade TX aluminum alloy with a high-end anodized finish, the G4 Classic undergoes detailed CNC machining to deliver a smooth, corrosion-resistant surface and ergonomic winged design. The device combines premium aesthetics with practical design features such as recessed stepless airflow control.
At its core, the G4 Classic offers dual-sensor intelligence for near-perfect reliability, with hardware-level trigger accuracy rated at 99.999%. The 35W output and high-density 1400mAh battery are paired with UWELL’s Pro-FOCS 4.0 Flavor Technology for precise e-liquid flavour reproduction. A transparent e-liquid window and U2 Anti-Leak system provide added convenience for users.
The G4 Classic also incorporates dynamic RGB ambient lighting, offering gradient effects that respond to each draw, alongside intuitive controls for power, locking, and battery status. Personalisation continues with dual airflow and activation systems, giving users the choice between tactile button firing or auto-draw sensing.
Fully compatible with existing and upgraded CALIBURN GPP cartridges, including options that fit the G3 series, the G4 Classic ensures backward compatibility while enhancing comfort with a redesigned ergonomic mouthpiece.
Since its founding in 2015, UWELL has expanded to 80 markets, sold more than 38 million products, and filed over 300 patents. The company positions the G4 Classic as the culmination of its decade-long commitment to precision-engineered vaping technology.
