If you want a Uwell, you want a Caliburn — and that's where it gets confusing, because Uwell sells about a dozen of them and they don't all take the same pods. After years of selling every model, here's the short version: the Caliburn G5 is the best for most people, and at £14.99 we sell it for around £8 less than most UK shops. Below, the 10 best Uwell kits ranked, with verified specs, honest prices, and exactly which pod each one takes so you never buy the wrong pack.

How we ranked these Uwell kits
We didn't copy a spec sheet. We weighed what people actually buy, what long-term Caliburn owners recommend, and how each kit performs day to day — battery, flavour, pod life, simplicity and price. Where a kit has a real weakness, we say so, and we tell you who should pick something else. All specs are taken from Uwell's official figures; UK pods are 2ml.
1. Uwell Caliburn G5 — best overall and best value
The Caliburn G5 is the one to buy if you just want the best Caliburn without overthinking it. You get a 1600mAh battery, up to 35W, tap controls, and Uwell's newest GPP and Alpha pods — the Alpha pod is built specifically for longer pod life, which fixes the single most common Caliburn complaint. Resistances run 0.4 to 1.2 ohm, so it covers tight MTL through to a looser, warmer draw.
Pros: newest pod tech, great battery, brilliant flavour, and our price is unbeatable. Who it's not for: cloud-chasers — every Caliburn is a mouth-to-lung pod kit, not a sub-ohm machine. At £14.99 it's the smart buy.
2. Uwell Caliburn G4 Pro — most recommended, biggest battery
The Caliburn G4 Pro is the kit long-time vapers recommend more than any other Caliburn. It pairs the biggest battery in the range — 1800mAh — with up to 35W, a smart touch screen and a boxy, premium feel. It takes the GPP pods, so pod choice is wide.
Pros: best battery life, premium touch screen, the enthusiasts' pick. Who it's not for: anyone who wants the slimmest pocket device — the boxy body is chunkier than the tubes. £16.99.
3. Uwell Caliburn G4 — cult flavour favourite
The Caliburn G4 earns its place on flavour and balance — owners routinely call it the best-tasting pod they've used. It runs a 1300mAh battery, 5–35W adjustable power, a colour screen, and GPP pods from 0.4 to 0.9 ohm.
Pros: superb flavour, adjustable wattage, slim tube shape. Who it's not for: if you want the newest pods and the lowest price, the G5 beats it. £15.99.
4. Uwell Caliburn G3 Pro — best flavour and reliability
The Caliburn G3 Pro is the kit owners reach for when they want a dependable daily driver that just works. It's compact, runs up to 35W from a 1000mAh battery, and takes 0.4 and 1.2 ohm pods — a tight high-nicotine draw or a warmer, airier one.
Pros: excellent flavour, rock-solid reliability, pocketable. Who it's not for: heavy all-day vapers — the 1000mAh battery is the smallest of the Pro tier. £13.99.
5. Uwell Caliburn G3 — the best-selling classic
The Caliburn G3 is one of the most-reviewed pod kits in the UK for a reason: simple, reliable, great flavour. It has a 900mAh battery, up to 25W, and side-fill G3 pods in 0.6, 0.9 and 1.2 ohm mesh.
Pros: proven, easy side-fill, wide pod choice. Who it's not for: if you want the bigger battery, its own Lite version (below) actually beats it there. £13.99.
6. Uwell Caliburn G3 Lite — best budget bestseller
The Caliburn G3 Lite is the value champion, and our single best-selling Uwell kit — don't let “Lite” fool you. It actually has a bigger 1200mAh battery than the standard G3, runs up to 25W, and uses the same G3 pods. Vaping360 literally called it a “disposable destroyer,” and at this price it's the obvious switch from disposables.
Pros: big battery for the money, uses common G3 pods, brilliant value. Who it's not for: anyone wanting a screen or wattage control. At £9.49 it's the best cheap Caliburn.
7. Uwell Caliburn Explorer — two flavours at once
The Caliburn Explorer is the one genuinely different Caliburn: a dual-sided 4ml pod (2ml per side) lets you load two flavours and switch between them. It runs a 1000mAh battery up to 32W and uses the classic Caliburn G coils (0.8–1.2 ohm).
Pros: two flavours on the go, big combined capacity, unique. Who it's not for: anyone who finds two pods fiddly — a single-pod kit is simpler. £14.99.
8. Uwell Caliburn A2 — budget MTL classic
The Caliburn A2 is the cheap, do-everything pod that's racked up hundreds of reviews. A 520mAh battery, 13W, and a 1.0 ohm mesh pod give a tight, satisfying MTL draw — ideal for a first refillable or a backup.
Pros: dependable, dead simple, cheap. Who it's not for: big-battery seekers — 520mAh needs a daily charge. £12.99.
9. Uwell Caliburn AK3 — cheapest with the fastest charge
The Caliburn AK3 is your cheapest way into the Caliburn family, and it charges fully in around 15 minutes. A 520mAh battery, 13W, a 1.0 ohm top-fill pod and a magnetic connection make it about as simple as vaping gets.
Pros: lowest price, 15-minute fast charge, top-fill. Who it's not for: anyone who wants airflow control — it's fixed. £11.49.
10. Uwell Caliburn G5 Lite — newest budget
The Caliburn G5 Lite is the cheap way into Uwell's latest generation: a big 1600mAh battery, up to 35W, and the newer GPP pods — rare at this price. A brilliant budget pick if you want current pod tech without the flagship cost.
Pros: latest pods, huge battery for the money. Who it's not for: anyone wanting a screen. At £9.49 it ties as our cheapest Caliburn. Browse the full Uwell vape kits range.

Which Caliburn pod fits which kit? (the bit everyone gets wrong)
This is where people waste money. Caliburn kits use several different, non-interchangeable pod systems. Buy the wrong pack and it won't fit.
| Pod system | Fits these kits |
|---|---|
| GPP / Alpha pods | G5, G5 Lite, G4 Pro, G4, G3 Pro |
| G3 pods (side-fill) | G3, G3 Lite |
| Caliburn G coils | Explorer (and original Caliburn G / G2) |
| A-series pods | AK3 (shared with A3 / A3S / AZ3) |
| A2 pod | A2 only |
Match your pack to your kit using our Uwell pods page — replacement pods are far cheaper per puff than a new kit.
Which Caliburn should you buy by experience level?
New to refillables / off disposables: the Caliburn G3 Lite or AK3 — cheap, simple, fill and go. Pair with a 20mg nic salt.
Everyday vaper who wants the best: the Caliburn G5 — newest pods, great battery, best price. Or the G4 Pro for the biggest battery.
Flavour-chaser: the G4 or G3 Pro — both are praised for taste, with adjustable wattage to dial it in.
Before you buy: known Caliburn quirks (the honest bit)
Caliburns are reliable, but no pod kit is perfect. Here's what real owners report, and how to avoid it:
- Leaking or spitting: usually overfilling, the pod not clicked in flush, or too-thin liquid. Uwell's U² anti-leak design helps but isn't leak-proof. Don't overfill, and seat the pod firmly.
- Pod or coil life: the most common gripe — some owners burn through pods fast. Prime a new pod (let it sit filled for 5–10 minutes), don't chain-vape, and pick a higher-resistance pod for high-nicotine salts. The G5's Alpha pods are built to last longer. If you get a scorched taste, see our guide on why your vape tastes burnt.
- Gurgling: that's e-liquid in the air channel, almost always from pulling too hard. Draw gently. If it stops firing entirely, try our vape not hitting fixes.
Frequently asked questions
Which Uwell Caliburn is the best?
For most people, the Caliburn G5 — newest pods, strong 1600mAh battery, best flavour-to-price, and our price beats the high street by around £8. Long-time vapers often favour the G4 Pro for its bigger battery; budget buyers love the G3 Lite.
Is the Caliburn G5 better than the G4?
Yes, for most buyers. The G5 has a bigger 1600mAh battery, tap controls, and the newer longer-life Alpha pods. The G4 is still an excellent, slightly more flavour-focused tube — but the G5 is newer and cheaper here.
Are Uwell Caliburn kits refillable?
Yes. Every kit here is refillable — you fill the pod with your own e-liquid and replace the pod when the flavour fades.
Do all Caliburn pods fit every kit?
No — this is the big one. There are several pod systems (GPP, G3, Caliburn G coils, A-series, A2). See the compatibility table above before you buy pods.
Why is my Caliburn leaking?
Usually overfilling or a pod that isn't seated flush. Don't fill past the line, click the pod in firmly, and avoid very thin (high-PG) liquid in low-resistance pods.
Why is my Caliburn gurgling or spitting?
You're pulling too hard — e-liquid gets into the air channel. Take slower, gentler draws and it clears.
How long do Caliburn pods last?
Around 1–2 weeks per pod with normal use. Prime new pods and don't chain-vape to get the most from them; the G5's Alpha pods last noticeably longer.
What nicotine strength should I use?
For these MTL kits, a 20mg (2%) nic salt is the sweet spot coming off disposables. Our 10 best 10ml nic salts guide covers the flavours that pair best, or browse all e-liquid.
Which Caliburn charges fastest?
The AK3 — around 15 minutes for a full charge via USB-C.
The bottom line
If you want one Caliburn and the best price, buy the Caliburn G5 at £14.99. New to refillables? The G3 Lite. Want the biggest battery? The G4 Pro. Whatever suits you, there's a Uwell here for it — see the full range on our Uwell vape kits page.
