Caliburn G Replacement Coils by Uwell

What Are Caliburn G Replacement Coils by Uwell?

Caliburn G Replacement Coils by Uwell are the official replacement heating elements made for the Caliburn G pod system. Every pod vape relies on a coil to turn e-liquid into vapour, and that coil is a consumable part, it doesn't last forever. When your Caliburn G starts tasting burnt, flat, or simply "off," a fresh coil is almost always the fix, and these are the coils built specifically for that job.

Uwell designed the Caliburn G coil around a mesh heating structure rather than a traditional single or dual coil wire. Mesh coils heat more evenly across a larger surface area, which generally means better flavour reproduction and a smoother draw compared to older round-wire coil designs. If you've owned a Caliburn device before, you'll notice the G-series coils are a refinement of that same reliable pod-based approach Uwell is known for.

Built for the Caliburn G Pod System

These coils are engineered to slot into Caliburn G-series pods, so they're the correct choice if you're running a Caliburn G device and need a like-for-like replacement rather than a coil designed for a different pod shape or connector. Uwell keeps coil design consistent within a device family, which is why sticking to the manufacturer's own replacement coil, rather than a generic third-party alternative, is the safest way to guarantee a proper seal, correct airflow, and no leaking.

We'd rather give you accurate general guidance than guess at an exact compatibility list: if you're unsure whether a coil fits your specific Caliburn G pod, check the coil's connector style against your existing pod before fitting, or get in touch with us and we'll help you match it up correctly.

Coil Resistance and Vaping Style

Caliburn G coils use a mesh build designed around mouth-to-lung (MTL) vaping, the tight, cigarette-like draw that most pod system users prefer, especially with nicotine salt e-liquids. This isn't a sub-ohm, cloud-chasing coil. It's built for a restricted airflow, warmer vapour, and a more concentrated flavour hit on each puff, which is exactly what makes Caliburn devices popular as an everyday, discreet vape.

Because resistance and wattage ranges can vary slightly between coil batches and pod variants, we'd always recommend checking the resistance printed on the coil itself and vaping within the range recommended by Uwell, rather than pushing wattage higher than the coil is rated for.

When to Replace Your Caliburn G Coil

Coils wear out through everyday use, the wicking material saturates, the mesh element degrades, and flavour production drops off. Most vapers get somewhere between one and three weeks out of a coil depending on how often they vape and what they're using it with, but it's really about the signs, not the calendar. Replace your coil when you notice:

• A burnt or scorched taste, especially on the first few puffs of the day
• Noticeably weaker flavour compared to when the coil was new
• Gurgling, spitting, or a sudden change in draw resistance
• Leaking or e-liquid pooling around the mouthpiece
• Reduced vapour production even at your usual wattage

Thicker e-liquids, higher VG blends, and heavier daily use will generally shorten coil life, while lighter use and thinner nic salt liquids tend to stretch it out. There's no single "correct" lifespan, treat the taste as your best indicator.

How to Fit and Prime a New Caliburn G Coil

Getting a new coil ready properly takes a couple of minutes and makes a real difference to how it performs from the first puff. A dry hit on an unprimed coil is the single most common reason people think a new coil is faulty when it isn't.

• Remove the old coil from the pod and empty out any remaining e-liquid before fitting the new one.
• Insert the new coil into the pod, pushing it firmly into place until it seats securely against the base, a loose fit is a common cause of leaking.
• Prime the coil before filling by adding a few drops of e-liquid directly onto the visible mesh or wicking ports, letting it soak in fully. This pre-saturates the cotton so the coil isn't firing dry the moment you fill the pod.
• Fill the pod with your chosen e-liquid, then let it stand for five to ten minutes so the wicking material can fully absorb the liquid before vaping.
• Take slow, gentle puffs for the first few draws rather than firing on full power straight away, giving the coil a chance to settle in.

Skipping the priming step is the most common reason a brand-new coil tastes burnt on its very first use, it's not a faulty coil, it's a dry one.

Getting the Best Flavour and Longest Coil Life

A few habits make a genuine difference to how long a Caliburn G coil lasts and how good it tastes along the way:

• Keep your pod topped up, never let it run dry, as firing a coil with little or no e-liquid left will burn the wick almost instantly.
• Give a new pod a rest of a few minutes after filling before vaping heavily, to let the coil fully saturate.
• Avoid chain vaping for long stretches, which doesn't give the wicking material time to re-soak between puffs.
• Store spare coils somewhere cool and dry, away from direct sunlight, until you're ready to use them.
• If flavour starts fading gradually rather than dropping suddenly, it's often just the coil reaching the end of its natural life rather than a fault, that's the point to swap it out.

Keeping a couple of spare coils on hand means you're never stuck vaping on a tired one out of convenience, which is usually when flavour quality suffers most.

UK Compliance and Adult Use

Caliburn G pods, like all UK-sold vape tanks and pods, are limited to a maximum capacity of 2ml under TPD (Tobacco Products Directive) regulations. This applies to the pod itself rather than the coil, but it's worth knowing if you're pairing a fresh coil with a new pod.

These coils are intended for use with nicotine-containing e-liquids, including nicotine salts, which in the UK are legally capped at a maximum strength of 20mg/ml (2%). Vaping products are for adult smokers and vapers aged 18 and over only. We do not sell nicotine vaping products to anyone under 18, and age verification applies at checkout.

Frequently Asked Questions

How many puffs does a Caliburn G coil last?

There's no fixed puff count Uwell publishes for these coils, and it varies a lot between users. Instead of counting puffs, watch for the practical signs, burnt taste, weaker flavour, or gurgling, and replace the coil when those show up rather than sticking to a rigid schedule.

Why does my new coil taste burnt straight away?

This is almost always down to priming, not a faulty coil. If e-liquid hasn't had time to soak fully into the wicking material before you start vaping, the coil fires dry on those first few puffs. Prime with a few drops of e-liquid on the mesh, fill the pod, and let it sit for several minutes before use.

Can I use a different brand's coil in my Caliburn G?

Third-party coils aren't designed to Uwell's exact specifications, so fit, seal, and performance can be inconsistent even if a coil looks similar. Using the manufacturer's own Caliburn G coils is the most reliable way to avoid leaking and get the flavour and vapour production the device was designed to produce.

Why is my pod leaking after I changed the coil?

Leaking after a coil change is usually caused by the coil not being pushed fully into place, overfilling the pod, or vaping before the e-liquid has had time to saturate the wick. Double-check the coil is seated securely and give a newly filled pod a few minutes to settle before vaping.

Do I need to prime the coil if I'm in a hurry?

You can skip it, but you'll likely get a harsh or burnt-tasting first few puffs and put unnecessary strain on the coil from the very start. The couple of minutes it takes to prime properly pays off in both taste and how long the coil ultimately lasts.

How do I know which Caliburn G coil to buy?

Match the coil to the specific pod you're currently using, check the connector shape against your existing coil if you're ever unsure. If in doubt, reach out to us before ordering and we'll help make sure you're getting the right replacement for your device.
