Uwell Caliburn GPP 2 mL Pods: Compatibility and Refilling

Uwell Caliburn GPP 2 mL replacement pods are refillable cartridges sold in a four-pack. They are for adults who already have a compatible G Pod Platform device and want spare pods with a smaller liquid capacity. Each cartridge holds the e-liquid and contains the heating element, so replacing it refreshes the part most likely to wear out. This pack does not include a Caliburn device or bottled e-liquid.

Which Caliburn devices use GPP pods?

GPP means G Pod Platform. Uwell uses the platform across supported Caliburn G5, G4 and G3 models, including newer pen-style and KOKO devices. The word Caliburn alone is not enough to confirm fit: older pod families can use different cartridges. Check your device model, look for the GPP designation and confirm the compatibility information on the specific pack before ordering.

The 2 mL four-pack product page is also where you should check which resistances are currently offered. Uwell lists GPP options such as 0.4, 0.6, 0.9 and 1.2 ohms across the platform, but that does not mean every option is available in every listing. Select the resistance deliberately rather than choosing by pack image alone.
