Uwell Caliburn G4 Pro Koko Pod Vape Kit FAQ
The Caliburn G4 Pro Koko works with Caliburn GPP cartridges, which are also compatible with G3 devices.
The 2000mAh cell is built for all-day use; actual runtime depends on wattage, coil and vaping frequency.
No U² anti-leak tech and the GPP design make top-ups quick and clean when used correctly.
Storm gives an instant hit, Waves smooths power delivery, and Custom lets you set a power curve (start/middle/end).
For MTL, use 50/50 or nic salts with 0.8–1.2 Ω pods for RDL, use 50/50 or light 60/40 with 0.4–0.6 Ω pods.
