If you’re after simplification without compromise, the Caliburn G4 Mini delivers exactly that.
It condenses the power and flavour of its namesake into a sleek, lightweight frame without losing the Caliburn character.
Design-wise, the Mini is one of the most pocket-friendly kits UWELL has ever put out…the device keeps things ultra-slim while still managing to feel sturdy and well-built.
It’s available in a range of vibrant colourways that are bold without being flashy, and an LED light keeps you updated on your battery levels with a simple green/blue/red system.

The upgraded 1100 mAh battery provides solid all-day performance for most users, and thanks to USB‑C fast charging, you can get it back to full power in around an hour.
Performance-wise, it’s driven by a single 0.6 Ω GPP pod, pushing up to 35 watts and delivering thick, flavour-rich puffs.
UWELL’s updated flavour tech (PRO-FOCS 4.0) brings around a thirty-five percent boost in taste and coil lifespan over previous pod generations.
Refilling is quick and easy with a side-fill port, and the pods pop in securely with a satisfying magnetic click.
The airflow options are particularly strong for such a compact kit. A side slider paired with pod rotation gives you meaningful control over your inhale — from a nice tight MTL to a slightly looser RDL style.
There’s no fire button or screen here, just smooth, reliable auto-draw activation. For fans of earlier Caliburn models, this version keeps things familiar but noticeably more refined.
