Uwell Caliburn Range Compared: G4 vs G4 Pro vs G5 (and the Rest)
Ask ten UK vape shops for a refillable recommendation and the word you'll hear most is Caliburn. Uwell's pod family has been the default answer for years — but the range now spans multiple generations and sub-lines whose names explain nothing. Here's every Caliburn we stock, organised so the choice makes sense.
The current flagships: G4, G4 Pro and G5
The Caliburn G4 is today's mainstream pick: 1300mAh, up to 35W through Uwell's PRO-FOCS 4.0 flavour tech, a compact colour screen, and two characters in one kit — Storm mode for dense vapour, Wave for smooth balance. The G4 Pro scales it up with an 1800mAh battery and the line's first full touchscreen — 2.51 inches of shatterproof glass — while the G5 is the newest generation: 1600mAh, upgraded GPP Alpha pods with extended coil life, and tap-anywhere control — tap the body three times to switch modes.
Why the pod platform is the real story
The modern Caliburns share the GPP pod ecosystem — pods cross-fit between the G3, G4, G4 Pro and G5 (2ml TPD versions in the UK). That's rare and valuable: your spare pods survive a device upgrade, and one pod purchase serves whichever Caliburn is charged. It's a quiet reason the family keeps its recommendation status — the ecosystem rewards loyalty instead of punishing it.
The wider family
Around the flagships sit the earlier generations and sub-lines we also stock: the G2 and G3 Lite for classic simplicity, the budget-friendly A2, A2S, A3 and AK series — the lightest, simplest Caliburns, ideal first kits — and the Tenet and Koko designs for anyone who prefers retro styling or the squat, wide format over a stick. All are MTL-focused pod kits at heart. Browse everything in our Uwell collection.
Which Caliburn should you buy?
The safe answer: G4 — the balanced modern default. Battery and features: G4 Pro. Newest tech: G5. Tightest budget: the A-series. Style-led: Tenet or a Koko. Whichever you pick, the pairing is the same: 10–20mg nic salts for the smooth MTL draw the Caliburn was built around — our strength guide helps pick the mg.
Frequently asked questions
Are Caliburn pods interchangeable?
Within the modern GPP platform, yes — G3, G4, G4 Pro and G5 share pods. Older lines (G2, A-series, Tenet) use their own pod formats, so match pods to your exact model there.
Is the Caliburn good for quitting smoking?
It's arguably the category's best-known answer to exactly that: tight cigarette-like draw, dependable coils, and nic salt compatibility at 20mg for pack-a-day switchers.
Caliburn G4 or G5 — which is better?
The G5 is newer with a bigger battery and longer-lived Alpha pods; the G4 is cheaper with the proven Storm/Wave modes. Both run shared GPP pods, so neither choice locks you in. 18+ only.
