Uwell

Uwell built its reputation on one product line: the Caliburn. Since launching the original in 2019, the Shenzhen-based manufacturer has iterated through the Caliburn G, G2, G3, G4, and A2 — each refining draw activation, coil longevity, and pod design. At VapeGreen, Uwell's catalogue is almost entirely Caliburn-related, which says something about how dominant that single series has become.

Most of the demand sits with consumables. Replacement pods and vape coils for the G, G2, and A2 models make up the majority of orders, reflecting a large installed base of Caliburn users who keep coming back for spares. The devices themselves remain competitive — compact, affordable, and well-suited to nic salt e-liquids — but it's the ecosystem of compatible accessories that keeps Uwell relevant year after year.
