Uwell Caliburn G & G2 Coils: What’s New and Why It Matters

The Uwell Caliburn series has built a reputation for combining simplicity and performance in compact pod systems. With the release of the Caliburn G and G2, Uwell introduced a fresh lineup of replacement coils that elevate the experience for users of the Caliburn G, G2, X, GK2, Tenet and other compatible devices. This article explores the new coil options, their compatibility, how they improve flavour and vapour, and why they make all the difference to your vape setup.

Introducing the New Coil Options

Caliburn G and G2 coils are available in three variations:

• 0.8Ω mesh coil
• 1.0Ω standard coil
• 1.2Ω mesh coil

These coils represent a shift in versatility and performance. The two mesh coils provide rapid, even heating for enhanced flavour and cloud production, while the standard 1.0Ω coil maintains a classic mouth-to-lung (MTL) draw with discreet vapour. In this trio, there is a coil for almost every vaping preference — from tight, cigarette-like draws to relaxed restricted direct-to-lung (RDTL) sessions.

Broad Device Compatibility

One key benefit of the new coils is their interchangeability across several popular Caliburn devices. The Caliburn G and G2 themselves are designed around these coils, but they also fit the GK2, KOKO Prime, Tenet and Ironfist L Pods.

This cross-compatibility makes the coils flexible and cost-effective. You can own more than one device and test different resistances without investing in separate hardware.

Mesh vs Standard Coils: What’s the Difference?

Mesh coils contain a woven metal surface that heats e-liquid more evenly than traditional wire coils. This results in fast ramp-up time, consistent heating, optimised flavour delivery, and reduced dry hits. The 0.8 Ω mesh coil is tuned for RDTL, offering thicker vapour and a more open airflow. The 1.2Ω mesh coil leans to MTL, delivering smoother flavour with slightly more vapour than regular mouth-to-lung coils.

On the other hand, the 1.0Ω standard coil provides increased airflow and cooler vapour. Many users appreciate the simplicity and dependability of standard coils. The draw is familiar and the coils are economical on e-liquid which has plenty of advantages for your wallet.

Uwell Caliburn G & G2 Replacement Coils

• Three coil options: 0.8Ω mesh, 1.0Ω standard, and 1.2Ω mesh for MTL and RDTL styles
• Compatible with multiple Uwell kits including Caliburn G, G2, X, GK2, and Tenet
• Easy push-fit installation and ideal for 50/50 or high PG e-liquids.

Easy Installation: Push-Fit Convenience

Replacing coils has never been simpler. Uwell’s push-fit design means all you need to do is pull out the old coil and push in a new one — no screws, no fuss. This clean installation method minimises leakage and mess, making the process quick and beginner-friendly.

For users who dislike handling coil heads or unscrewing them in small pods, the push-fit method is a welcome improvement. It also encourages changing coils as soon as performance drops, which keeps flavour consistent and reduces wasted liquid.

Flavour and Vapour Tailored to Your Style

The mesh coils excel at enhancing flavour. The 0.8Ω coil works best with freebase e-liquids and mid-VG 50/50 blends, producing bold taste and denser clouds suitable for RDTL sessions. The 1.2Ω coil, also using mesh, targets MTL vapers who want clean taste without excessive vapour. Combined with nicotine salts or 50/50 freebase e-liquid, it delivers the perfect balance of taste and throat hit.

Meanwhile, the standard 1.0Ω coil speaks to traditional MTL users — minimal vapour, familiar draw, and great nicotine satisfaction with discreet clouds. Choose mesh or standard based on your preference: bold and flavourful or subtle and smooth.

E-Liquids and Coil Compatibility

All three coils perform best with 50/50 VG/PG or high-PG e-liquids. These thinner liquids wick faster, avoiding dry hits or flooding issues. Higher VG liquids are better suited to sub-ohm devices with stronger airflow; here, stick to balanced blends for reliable performance.

Freebase liquids (12-18mg), nicotine salts (10-20mg) and or high PG e-liquids (0-18mg) work well with the 1.0Ω and 1.2Ω coils, while low-strength freebase e-liquids (3-6mg) and nicotine salts (0-10mg) pair well with the 0.8Ω coil.

Enhancement of User Experience

The coil lineup significantly improves from previous Caliburn generations:

• Pods are easier to maintain with push-fit design.
• Coil life is extended—which means more satisfaction per coil.
• These upgrades elevate the Caliburn series from simple starter kits to versatile daily drivers.

How to Choose Between the Three Coil Options

Your choice depends on your vaping style:

• 0.8Ω mesh coil: For users who enjoy looser draws, richer clouds and flavour.
• 1.2Ω mesh coil: Strikes a balance between flavour and discreet MTL performance.
• 1.0Ω standard coil: Perfect for those adjusting to nicotine salts or wanting a discreet, traditional draw.

Experimenting with all three can help you refine your vaping preferences.

Pro Tips for Coil Setup and Use

• Always prime coils by dripping a few drops into the cotton before first use; wait five minutes to avoid dry hits.
• Start at low wattage and gradually increase to find the sweet spot.
• Clean contacts during coil changes to keep your device performing.
• Replace coils when flavour fades or if a burnt taste appears.

Coil Performance Across Devices

Coil consistency is measured by flavour retention, vapour production, coil longevity and leak resistance:

• Mesh coils consistently provide balanced, full-bodied flavour, even near the end of life.
• Standard coils deliver consistent, traditional MTL draw with minimal leaks.
• All coils maintain strong flavour through the cartridge life and can handle multiple refills.

Environmental and Economic Considerations

The ability to reuse pods across coils and devices contributes to reduced plastic waste. Consider purchasing coils in multipacks to minimise shipping impact. This multi-device design aligns with FREESMO’s ethos of better vaping through sustainability.

Final Thoughts: Why This Coil Lineup Matters

The flexible coil options enhance the Caliburn ecosystem by offering:

• Performance for MTL and RDTL vaping styles.

• Easy maintenance.

• Cost-effective use.

• Support across multiple devices.

• Strong performance with 50/50 liquids.
