How We Ranked Top Uwell Devices
We did not just look at the numbers and explain them to you. These picks come from what UK vapers actually buy day to day, what long-term Caliburn owners keep recommending, and how each device holds up on the things that matter: battery life, flavour, pod life, ease of use, and how simply it does its job.
Where a model has a real weakness, we say so, and we tell you who should pick something else instead. Everything here is a genuine UK-market device with 2ml pods, judged on everyday use rather than marketing figures.
Best Uwell Caliburn Pod Kits (Compared)
Nearly everyone searching for a Uwell wants a Caliburn, so this is where most of you will land. These are all compact, refillable pod kits with a tight mouth-to-lung draw, the kind of vape you fill with your own e-liquid and top up when it runs low.
1. Caliburn G5: The One To Buy If You Are Not Sure
The Caliburn G5 is the safe default. You get a 1600mAh battery, up to 35W, triple-tap controls, and Uwell's newest GPP Alpha Pods, which are built to last longer between changes.

Resistances span a tight, high-nicotine draw through to a warmer, airier one, so it flexes to how you vape. It is not a cloud machine, because no Caliburn is, but for everyday flavour and battery life it is hard to beat.
2. Caliburn G4 Pro: The Biggest Battery In The Family
Long-time Caliburn owners recommend the G4 Pro more than any other model, and the reason is stamina. An 1800mAh battery is the largest in the range, paired with up to 35W and a proper touchscreen.
#product

It is a boxier, more premium shape than the slim tubes, so it will not disappear into a coin pocket, but if you hate charging daily, this is your kit. It takes the widely stocked GPP pods.
3. Caliburn G4: Still The Flavour Favourite
Ask which Caliburn tastes best, and plenty of owners still say the G4. It runs a 1300mAh battery, adjustable power from 5W to 35W, and a colour screen, with GPP pods to dial in the draw.
#product
https://piratevapes.co.uk/products/uwell-caliburn-g4-pod-kit
Slimmer than the G4 Pro, a touch smaller on battery, and beloved for taste. If the newest pods and the lowest price matter more, the G5 edges it, but on flavour alone the G4 has a loyal following.
4. Caliburn G3 Pro And G3: The Dependable Classics
The G3 Pro is the daily driver that just works: compact, up to 35W from a 1000mAh battery, and it takes GPP pods in a tight or a warmer resistance.
#product
https://piratevapes.co.uk/products/uwell-caliburn-g3-pro-pod-kit
https://piratevapes.co.uk/products/uwell-caliburn-g3-pod-vape-kit
The standard G3 is one of the most-reviewed pod kits in Britain for good reason. Simple, reliable, great flavour, a 900mAh battery and up to 25W, filled from the side with its own G3 pods.
Neither will win a spec-sheet contest. Both will still be going strong a year in.
5. Caliburn G3 Lite And G5 Lite: The Value Picks
Do not let "Lite" put you off. The G3 Lite is often the best-selling Caliburn of the lot, and it actually carries a bigger 1200mAh battery than the standard G3 while using the same pods.
#product

https://piratevapes.co.uk/products/uwell-caliburn-g5-lite-vape-kit
The G5 Lite is the cheap route into Uwell's newest generation, with a 1600mAh battery and the current GPP pods, which is rare at the price.
Neither has a screen or wattage control. For a lot of people, that is one less thing to fiddle with.
6. Caliburn Explorer: Two Flavours, One Device
The Explorer is the odd one out, in a good way. Its twin-chamber pod lets you keep two flavours loaded at once and switch between them, or run both together. A 1000mAh battery, up to 32W, and it uses the classic Caliburn G coils.
#product

Fun if you get bored of a single flavour halfway through the day. Slightly more faff than a single-pod kit, which is the trade-off.
7. Caliburn A2 And Ak3: The Simplest Way In
These are the fill-and-go pods. The A2 is a cheap, dependable MTL kit with a 520mAh battery, 13W, and a 1.0 ohm mesh pod, ideal as a first refillable or a backup.

https://piratevapes.co.uk/products/uwell-caliburn-ak3-pod-kit
The AK3 is the cheapest door into the Caliburn family and charges fully in around 15 minutes, with a magnetic, top-fill pod and no settings to learn.
Small batteries, so expect a daily charge, but for pure simplicity they are spot on.
Beyond the Caliburn: Tanks And Bigger Clouds
Uwell is not only pods. If you have moved past mouth-to-lung and want a warmer, airier, direct-to-lung hit with more vapour, the brand's Crown and Valyrian tanks are the route.
These are sub-ohm tanks that sit on a separate battery, so you pair them with one of our DTL Tank setups and a suitable Vape Mod.
The Crown series in particular has a long reputation for flavour at higher power, and it runs on shortfill e-liquid rather than the high-strength salts you would use in a Caliburn. It is a different style of vaping, and worth knowing about before you assume Uwell only does pods.
Cloud-chasers, this is your corner of the range.
Which Uwell Vape Kit Should You Choose?
The line-up makes more sense once you match it to how you actually vape.
Coming Off Disposables
Single-use disposable vapes were banned from sale across the UK on 1 June 2025, which is what sent a lot of people looking for a refillable they will not regret.
Start simple: a Caliburn G3 Lite or an AK3, filled with a 20mg (2%) nic salt for a familiar throat hit. Our 20mg Nic Salts are the closest match to what a disposable delivers, and a refillable pod means you top up rather than throw the whole thing away.
The Everyday All-Rounder
If you vape all day and want the best without overthinking it, the Caliburn G5. Newest pods, strong battery, clean flavour. The G4 Pro if battery life is the thing you care about most.
Chasing Flavour
The G4 or the G3 Pro. Both are praised for taste, and both give you a little wattage control to fine-tune it. Pair them with a resistance on the tighter side for high-strength salts.
Bigger Clouds
If MTL feels too restrictive, step across to a Crown or Valyrian sub-ohm tank and a mod. More power, more air, more vapour, and a different e-liquid to suit.
Lowest Running Cost
The cheapest kit you are happy with, then reusable pods and your own bottle of e-liquid. You will find the best value in MTL Vape Kits at the simpler end, because the ongoing spend is what adds up, not the kit.
Which Uwell Pod or Coil Fits Which Device?
This is the bit people get wrong, and it costs them money. Caliburn kits do not all use the same pod, and buying the wrong pack is the most common Uwell mistake. Match your kit to the right system before you order.
| Pod or coil system | Fits these devices |
|---|---|
| GPP and GPP Alpha pods | G5, G5 Lite, G4 Pro, G4, G3 Pro |
| G3 pods | G3, G3 Lite |
| Caliburn G coils | Explorer, plus the original Caliburn G and G2 |
| A-series pods | AK3, shared with A3, A3S and AZ3 |
| A2 pod | A2 only |
| Crown coils | Crown sub-ohm tanks |
When a pod's flavour fades, you replace the pod, not the kit, which is far cheaper per puff. Grab the right pack from our Replacement Pods range, and if you run one of the coil-based Caliburns, the matching Uwell Coils are there too.
Getting The Best From A Uwell (Common Quirks And Fixes)
No pod kit is perfect, so here is the honest bit. These are the niggles owners report, and how to sidestep them.
Leaking or spitting usually comes down to overfilling, a pod that is not clicked in flush, or liquid that is too thin for the resistance. Do not fill past the line, seat the pod firmly, and the U-shaped anti-leak structure does the rest.
Short pod life is the classic Caliburn gripe. Prime a new pod by letting it sit filled for five to ten minutes before the first vape, avoid chain-vaping, and choose a higher-resistance pod for strong salts. The G5's Alpha pods hold up noticeably longer than the older ones.
Gurgling is nearly always e-liquid getting into the air channel from pulling too hard. Draw gently, and it clears. If you want the full run-down on getting more from any kit, our Vaping Guides go deeper.
FAQs
Which Uwell Caliburn Is Best?
For most people, the Caliburn G5. Newest pods, a strong 1600mAh battery, and the best flavour-to-simplicity balance in the range. Long-time vapers often lean towards the G4 Pro for its bigger battery, and budget buyers love the G3 Lite.
Are Uwell Caliburn Kits Refillable?
Yes. Every Caliburn is a refillable pod kit. You fill the pod with your own e-liquid and replace the pod when the flavour drops off.
Do All Caliburn Pods Fit Every Kit?
No, and this is the big one. There are several separate pod systems: GPP, G3, Caliburn G coils, A-series and the A2 pod, and they are not interchangeable. Check the compatibility table above before you buy a pack.
Is The Caliburn G5 Better Than The G4?
For most buyers, yes. The G5 has a bigger battery, tap controls, and the newer longer-life Alpha pods. The G4 is still a superb, slightly more flavour-focused tube, so it is close, but the G5 is the newer all-rounder.
What Nicotine Strength Should I Use In A Caliburn?
Coming off disposables, 20mg (2%). It gives the familiar throat hit these MTL kits are built for. Once you have settled, many people step down to 10mg.
Why Is My Caliburn Leaking Or Gurgling?
Usually overfilling or too hard a draw. Fill the line below, seat the pod flush, and take slower, gentler pulls. Sorted.
Are Uwell Devices Still Legal In The Uk?
Yes. The June 2025 ban applied to single-use disposables only. Reusable, refillable, rechargeable devices like the Caliburn range remain fully legal, with 2ml pods and nicotine strengths up to 20mg/ml.
How Long Does A Caliburn Pod Last?
Around one to two weeks of normal use per pod. Prime it first and skip chain-vaping, and you will get the most out of each one. The Alpha pods on the newer kits last longer again.
