Caliburn G4 PRO Pod Ratings
Uwell gives 35W for the 0.4Ω pod. It doesn’t publish ratings for the others, so these are the ratings hands-on reviews and major shops agree on.
| Caliburn GPP pod | Rating |
|---|---|
| GPP pod, 0.4Ω | RDL, up to 35W |
| GPP pod, 0.6Ω | RDL, 25W |
| GPP pod, 0.9Ω | MTL, up to 15W |
| GPP pod, 1.2Ω | MTL, up to 13W |
We carry Caliburn GPP pods in packs of 3 and Caliburn G3 pods in packs of 4, and both fit.
How to Set Up the Caliburn G4 PRO
- Charge it: plug the G4 PRO into a USB-C charger.
- Fill it: fill a pod through the side fill port. You don’t need to take the pod out to refill it.
- Prime it: let the coil soak for a few minutes before your first puff.
- Vape: tap the screen to pick a mode and wattage, set the airflow, then draw to vape.
Who the Caliburn G4 PRO Is For
The Uwell Caliburn G4 PRO suits vapers who want touchscreen control, a custom puff curve and a bigger battery, from MTL to RDL. For a similar touchscreen in a shorter, wider body with a 2000mAh battery, see the Caliburn G4 PRO KOKO. For a smaller, lighter kit without a touchscreen, see the Caliburn G4.
Good to know: the battery is built in, and Uwell doesn’t list a charging cable in the box.
