A CNC-milled metal pod that punches above its size — up to 35W, stepless airflow, and Uwell's PRO-FOCS flavour tech.
Everything a daily vape should be — here's what you actually get for £22.49.
A 1400mAh cell comfortably clears a full day for most vapers, and tops up over USB-C.
Turn the power up to 35W for warmer, fuller flavour — or down for a cooler, tighter vape.
A stepless ring tunes the draw anywhere from tight and cigarette-like to open and airy.
Two refillable pods run tight MTL or airier RDL — top-fill in seconds with any 10ml e-liquid.

A heavier habit needs a stronger hit to feel satisfying. 20mg nic salt (the UK maximum) in a tight MTL setting is about as close to a cigarette as vaping gets.

The Caliburn line is the pod that made Uwell a household name for switchers, and the G4 is the most capable yet — CNC aluminium in the hand, up to 35W of adjustable power, and a stepless airflow ring that lets the draw grow with you.
"A first pod that a seasoned vaper is still happy to carry."
Every kit ships with a free nic salt matched to your strength, a full one-year warranty, and our price-match promise.
The Uwell Caliburn G4 Classic is a refillable pod kit built on a precision CNC-crafted aluminium body, packing a 1400mAh battery with adjustable output up to 35W into a genuinely pocket-friendly form factor. It runs on a dual pod platform that handles everything from tight MTL draws to more open RDL vaping, supported by twin auto-draw sensors, stepless airflow control, and Uwell's PRO-FOCS 4.0 flavour technology.
This isn't just a stylish device, it's a capable daily carry that earns its keep through consistent performance. It suits adult switchers moving away from cigarettes or disposables, everyday vapers after reliable flavour and solid build quality, and anyone who wants more airflow versatility than a basic single-pod kit provides. Available in four colours, it comes with a free nic salt, fast UK dispatch, and Vaping 101's full one-year warranty.
Introducing the Uwell Caliburn G4 Classic Uwell is one of the most trusted names in pod kit hardware, and the Caliburn G4 Classic sits comfortably near the top of what this price point can deliver. The CNC-crafted aluminium body gives it a premium, solid-in-hand feel that most similarly priced kits simply don't match. The aero-grade build, zirconia-smooth surface finish, and four distinct colour options make it easy to carry without it feeling like a compromise.
Available in 4 finishes — Abyss Blue, Alpine Green, Classic Black, Classic Silver.
Under the hood, the 1400mAh battery and 5W-35W variable output give you a reliable all-day charge for MTL and RDL vaping. The kit ships with two Caliburn G3 pods at different resistances, and it's also compatible with the full range of Caliburn GPP pods. That combination of G3 and GPP compatibility gives this device a genuine flexibility that most pod kits at this price can't offer.

We buy, test and film the devices we sell. Here's how the Caliburn G4 scored in our testing — and our full video review.
A proper metal pod. Up to 35W and stepless airflow give it real range, the CNC body feels a class above the price, and Uwell's PRO-FOCS flavour is among the best in a pod this size.
Picked the Abyss Blue and it hasn't left my pocket. Does exactly what the page says, turned up next day with the free e-liquid.
Battery easily lasts my day and it feels properly made. The Alpine Green looks even nicer in person.
Been vaping years and this covers everything I want. Knocked a star only because I wanted a spare pod, but no complaints otherwise.
