10 Best Caliburn Vapes In 2026: The Ultimate Buyer’s Guide

The Uwell Caliburn G3 Pro KOKO takes the classic G3 Pro internals and drops them into a square, lanyard-friendly KOKO body that lies flat in your pocket instead of rolling around. It runs a 1250mAh battery, hits up to 35W, and has a proper 1.8-inch colour screen showing wattage, battery percentage, and puff count. Airflow is fully adjustable, so you can dial it in from a tight MTL pull to a looser semi-restricted lung hit. This is the one to get if you want the flavour and control of a pro device without carrying something bulky.

2. Uwell Caliburn G4 Mini

For anyone who wants Caliburn quality without spending Caliburn money, the Uwell Caliburn G4 Mini is the sensible pick. It strips out the screen and fancy modes from the standard G4 but keeps the 1100mAh battery, 35W output, and dual airflow adjustment (side slider plus pod orientation). It's genuinely tiny, fits in a coin pocket, and still uses the newer GPP pods.

If you're buying your first ever MTL vape kit and don't want to overthink it, this is a brilliant no-fuss starting point.

3. Uwell Caliburn G4

The full-fat G4 adds a 0.85-inch colour screen, three menu themes, adjustable brightness, and two firing modes called Storm and Wave. Storm gives you a punchier throat hit, Wave keeps things smooth and consistent. Battery sits at 1300mAh, output goes up to 35W, and it uses the same GPP pods as the Mini, plus it's backwards compatible with G3 pods.

Reviewers consistently say the flavour jump from G3 to G4 is noticeable, especially in Storm mode.

4. Uwell Caliburn G3

Don't write off the original G3 just because newer models exist. It's still one of the most dependable Caliburn pod kit options out there, with a small monochrome display, up to 25W output, and rock-solid Caliburn G3 replacement pods that are cheap and everywhere. If you find one on sale, it's still an excellent everyday vape, especially for someone who just wants simplicity over screens and modes.

5. Uwell Caliburn GK2

The GK2 borrowed design cues from Uwell's Crown tank line, giving it a slightly more premium, boxy feel. It runs a 900mAh battery, uses Caliburn G pods, and leans hard into flavour thanks to its mesh coil options. It's smaller output than newer devices, but for tight MTL vapers who prioritise taste over vapour clouds, it still holds up well.

6. Uwell Caliburn A3S

The A3S is one of the more budget-friendly, and the most non-fancy one in the list. Simple draw-activation, an 1100mAh battery, and side-fill pods make it a great backup device or a gift for someone who's curious about switching from smoking but doesn't want to spend much upfront. It's not flashy, but it's honest, and honest goes a long way in this category.

7. Uwell Caliburn X

The Caliburn X introduced dual coil options in one pod and a bump up to 20W, giving you a bit more flexibility between a tighter MTL draw and a slightly airier pull. Battery life is solid at 950mAh for its size, and the pods are widely stocked. It sits nicely between the ultra-basic models and the screen-equipped Pro devices.

8. Uwell Caliburn AK2

The AK2 is essentially Caliburn's answer to people who wanted a pen-style form factor instead of the classic slab shape. It holds 2ml of juice, runs up to 15W, and uses replaceable Caliburn A2 pods. It's compact, light, and easy to hold like a pen, which some vapers genuinely prefer over the flatter designs.

9. Uwell Caliburn KOKO Prime

This most portable one. The KOKO Prime is built around a 690mAh battery and a super slim body designed to be worn on a lanyard, literally around your neck. Output tops out around 16W, which keeps things gentle and gives you excellent battery efficiency for its size. It's ideal for someone who wants a discreet, grab-and-go vape rather than a powerhouse.

10. Uwell Caliburn Tenet (G2 Series)

Rounding out our list is the Tenet, part of the Caliburn G2 family. It runs a 750mAh battery, up to 18W output, and uses a leather-effect finish that still looks smart years after release. It's a nostalgic favourite for a lot of long-term Uwell fans, and the pods remain in decent supply, making it a low-maintenance option if you already own one.

Who Should Actually Buy A Caliburn?

Not every vaper needs the same thing, so it's worth being honest about who these devices suit best. If you're an ex-smoker who wants something that feels familiar and doesn't overwhelm you with settings, almost any Caliburn on this list will do the job. If you're a flavour chaser who's tried a few pod kits already and wants more nuance in your vape, lean toward the Pro or G4 range. And if portability is your main concern, whether that's a lanyard-style KOKO Prime or a coin-sized G4 Mini, Uwell has genuinely thought about that use case rather than bolting a lanyard hole onto a design as an afterthought.

There isn't a single best Caliburn for everyone. There's a best Caliburn for your specific vaping habits, and that's exactly why this list has ten different options instead of one.

Budget matters too. If you're not sure yet whether vaping is even for you, starting with something like the A3S or G4 Mini keeps your initial spend low. Once you know your preferred nicotine strength, draw tightness, and flavour type, upgrading to a Pro-tier device becomes a much easier decision, because you'll actually know what you're upgrading for instead of guessing.

Quick Comparison

Here's a quick side-by-side of the battery and output figures across our top picks, so you can compare at a glance before scrolling back up to read the full breakdown.

Caliburn Replacement Pods: Which One Fits Your Device?

This trips people up constantly, so let's clear it up. Not every Caliburn pod fits every Caliburn device, even though they all share the family name. Caliburn G3 replacement pods work with the G3, G3 Pro, and G3 Pro KOKO. Caliburn G4 replacement pods (also called GPP pods) fit the G4 and G4 Mini, and they're also cross-compatible with G3 devices. Always check your device model before ordering pods, since a wrong pod simply won't seal properly and will leak. Buying the wrong pod is the single most common mistake first-time Caliburn buyers make, so always match the pod code to your exact device model.

Refillable Pod Vape Vs Disposables: Why Caliburn Wins Long-Term

A refillable pod vape like any Caliburn model costs more upfront than a disposable, but the maths flips fast. A disposable lasts a few days and then goes in the bin. A Caliburn device lasts months or years, and you're only replacing a £3-4 pod every one to two weeks. Over six months, the savings are significant, and you're not adding to disposable vape waste either, which UK regulations are increasingly cracking down on.

Mtl Vape Kit Or Dtl? Which Caliburn Suits Your Style

Most Caliburn devices are built around mouth-to-lung vaping, where you draw vapour into your mouth first, then inhale it, just like a cigarette. This is exactly why Caliburn devices are so popular with people quitting smoking. A few models, like the G3 Pro KOKO and G4, let you loosen the airflow toward a semi-direct lung style if you prefer bigger clouds and a softer draw.

If you're coming from cigarettes, stick with a tighter MTL vape kit setting. It'll feel far more familiar and satisfying.

Caring For Your Caliburn Pod Kit

Simple maintenance massively extends coil life. Let a new pod sit filled for five minutes before your first puff so the coil soaks up juice properly. Avoid chain vaping on a single pod for hours without a break, since dry hits burn the coil out early. Wipe the contacts occasionally, and store spare pods with the fill port covered to stop them drying out. Most pods last one to two weeks with normal daily use.

FAQ’s

1. How long does a Caliburn pod last before it needs replacing? 

A. Most people get one to two weeks out of a single pod with regular daily vaping. Flavour fading, a burnt taste, or gurgling sounds are all signs it's time to swap it out.

2. Can I use G4 pods in a G3 device, or the other way round? 

A. G4 and GPP pods are generally cross-compatible with G3 devices, but original G3 pods don't always fit newer G4-only slots properly. Always check the specific pod packaging before buying.

3.Why is my Caliburn leaking from the bottom? 

A. This is usually caused by overfilling, a worn-out silicone seal, or vaping at a wattage that's too low for the coil installed. Try a fresh pod first, since seals do degrade with age and use.

4. Is Caliburn good for someone who's never vaped before? 

A. Yes, honestly one of the best options. The draw-activated firing, simple refilling, and tight MTL draw make it about as close to a cigarette experience as pod vapes get.

5. What nicotine strength should I use in a Caliburn? 

A. Most UK vapers switching from smoking start around 10-20mg nic salts. Heavier smokers often prefer the higher end, while lighter or social smokers do fine with 10mg or below.

6. Why does my new Caliburn pod taste burnt straight away? 

A. This usually means the coil wasn't given time to prime. Let a freshly filled pod sit for five minutes before vaping, and avoid firing it dry before it's had juice sitting in the coil.

7. Is the Caliburn G4 worth upgrading to from the G3? 

A. If flavour and a colour screen matter to you, yes. Most upgraders say the throat hit and vapour production noticeably improve, especially using Storm mode, though the G3 remains perfectly capable if you don't need the extras.

8. Are Caliburn vapes being banned along with disposables in the UK? 

A. No. The UK's disposable vape ban targets single-use, non-rechargeable devices. Refillable pod kits like every Caliburn model are unaffected and are actually one of the recommended alternatives.

Conclusion

Caliburn has stayed at the top of the pod vape world for one simple reason: it consistently delivers good flavour, decent battery life, and pods that are genuinely easy to find, without asking beginners to learn a new hobby just to vape. Whether you go for the pocket-sized G4 Mini, the display-equipped G3 Pro KOKO, or a budget-friendly A3S, you're getting a device built on years of refinement rather than a rushed trend release.
