The Uwell Caliburn G4 takes the Caliburn lineup into the next era with a robust 1,300 mAh battery, vivid color display, and refined pod system. With dual vaping modes (Storm and Waves), adjustable airflow, and broad pod compatibility, it delivers optimized performance for both MTL and RDL users. The higher wattage (up to 35 W) and mesh coils deliver bold flavor, while U² anti-leak and PRO‑FOCS 4.0 technologies extend pod lifespan and taste consistency. Lightweight and ergonomic, it's a stylish yet effective travel companion with both ease of use and customization.

Pros

Long-lasting battery (1300 mAh) gives all-day vaping for most users, with fast recharge times

Builds big flavor and decent vapor, especially with 0.4 Ω pod, thanks to PRO‑FOCS 4.0 and mesh coil design

Customizable airflow and dual activation modes let you fine-tune MTL or RDL experiences

Compatibility with G3 and GPP pods adds flexibility and ecosystem reuse

Leak-resistant design performs reliably, even after multiple refills

Best Use & Tips

Use the 0.9 Ω pod (shown as mouth-to-lung) with nicotine salts or 50/50 VG/PG e-liquids for smooth, tight draws.

Use the 0.4 Ω pod for restricted direct-lung (RDL) vaping—ideal for lower nicotine levels and more vapor.

Always let new pods prime ~5 minutes after filling before use to avoid dry hits.

Combine slider and pod orientation adjustments to customize draw tightness and airflow.

Switch between activation modes and vaping modes (Storm/Waves) through the multifunction button.

Keep device upright and charge separately from the pod if you detect condensation or minor leaks—routine contact cleaning helps maintain performance.
