What differs between the models

• Battery: built-in batteries run from 750mAh (Uwell Caliburn AZ3 17W) to 2000mAh (Uwell Caliburn G4 PRO KOKO 35W).
• Screen: 4 of the 11 models list a display.
• Draw activation: 8 of the 11 models are draw-activated or offer it alongside a button.
• Capacity: pods and tanks hold 2mL to 3mL.

How to choose

• Battery: a larger mAh figure means fewer charges per day.
• Pod capacity: 2mL pods need refilling more often than 3mL pods.
• Draw or button: draw-activated models work like a disposable. A fire button gives more control.
• Screen: models with a display show battery level and output.

E-liquid and upkeep

These are refillable devices: e-liquid is bought separately. Pods and coils wear out and are replaced every one to two weeks of regular use. If you are new to refillable devices, read how to use a pod system and the nicotine strength guide first. A burnt taste usually means a worn or dry coil: see why a vape tastes burnt.

All Uwell devices are on the Uwell brand page. For battery handling, see vape battery safety.
