How long do the Caliburn GPP Pods last?

Uwell has not officially stated an exact lifespan for Caliburn GPP pods, most users report getting around 20–30mL of e-liquid per pod before flavor and performance begin to decline.

Pod life can vary based on your wattage, e-liquid type (especially sweeter flavors), nicotine strength, and how the device is stored and used.
