Uwell Caliburn Vape Kits

Both are refillable mesh-coil pod kits and both vape well; the differences are on the device. The G4, especially the G4 Pro, adds a colour screen and wattage control, while the G3 keeps things simpler at a lower price. The G4 range uses GPP pods, and the G3 takes both G3 and GPP pods.

The G5 is the newest generation, with the G5 Koko bringing back the compact square format and the G5 Lite SE as an entry-level option. Both use GPP pods like the G4. The G4 Pro still leads on features such as the touchscreen and wattage control, so the choice comes down to size and screen rather than pod type.

It depends on what you want. For the most features, the G4 Pro has a touchscreen and wattage control. For a compact kit, the G5 Koko or G4 Mini are the smallest. For value, the G3 series does the basics well at a lower price. Each model page lists the full specs to compare.

The standard G4 keeps it simple with auto-draw and a small display, while the G4 Pro adds a full colour touchscreen, adjustable wattage and puff tracking. Both take the same GPP pods, so pods and coils are interchangeable between them.

Both are square Koko-format pod kits on GPP pods. The G4 Pro Koko carries the G4 Pro features including the touchscreen and wattage control, while the G5 Koko is the newer, simpler take on the square design. Pick the G4 Pro Koko for control, the G5 Koko for the latest compact build.
