Frequently Asked Questions About Uwell Caliburn GPP Pods

What devices are compatible with Caliburn GPP Replacement Pods?

Uwell Caliburn GPP Replacement Pods are compatible with the Caliburn G, Caliburn G2, and Caliburn GK2 devices. This cross-compatibility across the Caliburn G series makes these pods an excellent choice for anyone who owns multiple devices in the range, allowing you to use the same pods across different Caliburn G models.

How long do Caliburn GPP pods last?

The lifespan of Caliburn GPP pods varies based on usage habits and e-liquid type. For moderate users, expect 1-2 weeks of use per pod. Light users may extend this to 2-3 weeks, whilst heavy users typically get 5-7 days. Sweeter e-liquids tend to reduce pod lifespan as they can caramelize on the coil faster. Each pod can typically be refilled 8-12 times before needing replacement.

What is Pro-FOCS technology?

Pro-FOCS (Pro Flavour Optimized Coil System) is Uwell's proprietary flavour technology that enhances taste accuracy and consistency. The system uses precisely calibrated heating elements and optimized airflow to deliver pure, authentic flavour from your e-liquid. Pro-FOCS technology ensures you experience the true taste profile of your chosen e-liquid without any metallic or burnt notes.

How do I fill Caliburn GPP pods?

Filling Caliburn GPP pods is simple with the top-fill design. Remove the pod from your device, locate the silicone fill port on the side of the pod, lift the rubber stopper, insert your e-liquid bottle nozzle at an angle, and fill slowly until the liquid reaches just below the maximum fill line. Replace the stopper firmly, wipe away any excess liquid, and let the pod sit for 5-10 minutes before first use to ensure proper coil saturation.

What e-liquids work best with Caliburn GPP pods?

Caliburn GPP pods work best with 50/50 VG/PG e-liquids or higher PG ratios. They're compatible with both nicotine salt and freebase nicotine e-liquids, with nicotine strengths between 5mg-20mg recommended. Avoid high VG e-liquids (70VG or higher) as they're too thick for optimal wicking and may cause dry hits. For best flavour and performance, use quality e-liquids with moderate sweetener content.

Why does my Caliburn GPP pod taste burnt?

A burnt taste typically indicates the coil is degraded or wasn't properly primed. Common causes include: not allowing new pods to saturate for 5-10 minutes before use, chain vaping (taking puffs too frequently without allowing the coil to re-saturate), using e-liquid that's too thick, vaping when the pod is nearly empty, or simply reaching the end of the pod's lifespan. Always prime new pods properly and avoid vaping below the minimum fill line.

Can I refill Caliburn GPP pods multiple times?

Yes, Caliburn GPP pods are designed to be refilled multiple times until the integrated coil degrades. On average, you can refill each pod 8-12 times depending on your vaping habits and the type of e-liquid used. You'll know it's time to replace the pod when you notice diminished flavour, reduced vapour production, or a burnt taste that doesn't improve after refilling with fresh e-liquid.

Are Caliburn GPP pods leak-proof?

Caliburn GPP pods feature a leak-resistant design with secure seals and proper airflow engineering. Whilst no pod system is 100% leak-proof, these pods minimize leaking when used correctly. To prevent leaking: don't overfill beyond the maximum line, ensure the fill port stopper is firmly secured, store the device upright when possible, and avoid extreme temperature changes that can cause pressure differences.

How do I know when to replace my Caliburn GPP pod?

Replace your pod when you notice: significantly diminished flavour quality, reduced vapour production, a persistent burnt or off taste even after refilling, gurgling sounds, frequent leaking, or discoloured e-liquid. Even with proper care, all pods eventually need replacing as the integrated coil degrades over time. If cleaning and refilling don't restore performance, it's time for a fresh pod.

What's the difference between Caliburn G and GPP pods?

Caliburn GPP pods are the replacement pods designed for use with Caliburn G series devices. The 'GPP' designation refers to the pod model that's compatible across the G, G2, and GK2 devices. These pods feature the same Pro-FOCS technology and 2ml capacity, offering universal compatibility across the Caliburn G family of devices.

Can I use high VG e-liquids in Caliburn GPP pods?

We don't recommend using high VG e-liquids (70VG or higher) in Caliburn GPP pods. These pods are optimized for 50/50 VG/PG or higher PG ratios. High VG liquids are too thick and may not wick properly through the coil, leading to dry hits, burnt taste, and premature coil failure. Stick to 50/50 or 60/40 VG/PG ratios for optimal performance and flavour.

Are Caliburn GPP pods TPD compliant?

Yes, all Uwell Caliburn GPP pods sold in the UK are fully TPD (Tobacco Products Directive) compliant with a 2ml e-liquid capacity. They meet all UK and EU safety standards, including proper materials, safety features, and capacity restrictions. You can use these pods with confidence knowing they comply with all regulatory requirements.

Why is my Caliburn GPP pod gurgling?

Gurgling typically indicates excess e-liquid in the coil chamber or airflow pathway. Common causes include: overfilling the pod, condensation buildup, e-liquid that's too thin, or a flooded coil. To fix: remove the pod, gently blow through it to clear excess liquid, wipe the contacts, and ensure you're not overfilling. If gurgling persists, the pod may need replacing.

Educational Guide: Understanding Pod Systems and MTL Vaping

What is MTL (Mouth-to-Lung) Vaping?

MTL vaping replicates the draw of a traditional cigarette. You draw vapour into your mouth first, then inhale it into your lungs - exactly like smoking. The Caliburn GPP pods are specifically designed for MTL vaping, providing a tighter, more restricted draw that's ideal for those transitioning from smoking or preferring a cigarette-like experience. MTL vaping uses less e-liquid, produces less vapour, and works best with higher nicotine strengths, making it discreet and efficient.

Understanding Integrated Coil Pod Systems

Caliburn GPP pods feature an integrated coil design, meaning the coil is built into the pod and cannot be replaced separately. This design offers several advantages: consistent performance (each new pod has a fresh coil), no messy coil changes, optimal coil-to-pod fit for better flavour, and simplified maintenance. When the coil degrades, you simply replace the entire pod, ensuring you always get peak performance.

The Science Behind Pro-FOCS Technology

Uwell's Pro-FOCS (Pro Flavour Optimized Coil System) technology represents advanced engineering in flavour delivery. The system uses precisely calibrated heating elements, optimized wicking materials, and controlled airflow to ensure e-liquid is vaporized at the ideal temperature. This prevents overheating (which causes burnt taste) and underheating (which produces weak flavour), delivering pure, authentic taste from first puff to last. The technology also extends coil lifespan by preventing hotspots and uneven heating.

VG/PG Ratios and Pod Compatibility

E-liquids contain two main base ingredients: VG (Vegetable Glycerin) and PG (Propylene Glycol). VG produces vapour and adds smoothness, whilst PG carries flavour and provides throat hit. Caliburn GPP pods work best with 50/50 VG/PG ratios because this balance provides excellent flavour delivery, satisfying throat hit, and proper wicking through the coil. Higher VG liquids are too thick and may not wick efficiently, causing dry hits and premature coil failure.

Nicotine Salts vs Freebase Nicotine

Caliburn GPP pods work excellently with both nicotine types, each offering different benefits. Nicotine salts provide a smoother throat hit at higher concentrations (10-20mg) and absorb faster into the bloodstream, making them ideal for those transitioning from smoking who need quick nicotine satisfaction. Freebase nicotine offers a stronger throat hit and works well at lower concentrations (3-6mg), preferred by those who enjoy the traditional vaping sensation. Choose based on your needs: nic salts for smooth, efficient delivery, or freebase for classic throat hit.

Pod Maintenance and Care Tips

Prime New Pods: Always let new pods sit for 5-10 minutes after filling to ensure the coil is fully saturated
Avoid Chain Vaping: Wait 20-30 seconds between puffs to allow the coil to re-saturate with e-liquid
Monitor Liquid Levels: Refill when liquid reaches the minimum line to prevent dry hits and coil damage
Clean Contacts Regularly: Wipe pod and device contacts weekly with a dry cloth for optimal connection
Store Properly: Keep pods upright in cool, dry places away from direct sunlight and extreme temperatures
Use Quality E-liquids: Premium e-liquids with less sweetener extend pod lifespan significantly
Secure Fill Port: Always ensure the silicone stopper is firmly in place after filling to prevent leaking
Don't Overfill: Fill only to the maximum line to prevent flooding and leaking
Check for Damage: Inspect pods regularly for cracks or damage and replace if compromised

Maximizing Caliburn GPP Pod Lifespan

Use the recommended 50/50 VG/PG e-liquid ratio for optimal wicking
Avoid heavily sweetened e-liquids which caramelize and clog coils faster
Don't vape when the pod is nearly empty - always maintain liquid above minimum line
Take moderate-length puffs (2-4 seconds) rather than very long draws
Keep your device and pods at room temperature - avoid extreme heat or cold
Clean the pod exterior and contacts regularly to prevent residue buildup
Store filled pods upright to ensure even saturation and prevent leaking
Rotate between flavours to prevent taste fatigue and give coils a break
Start with lower wattage if your device is adjustable and increase gradually

Troubleshooting Common Issues

Weak Flavour

If you're experiencing weak flavour, try: ensuring the pod is properly seated in the device, checking that liquid level is adequate, cleaning the contacts, trying a fresh pod, or switching to a different e-liquid. Sometimes taste fatigue occurs from vaping the same flavour continuously.

Reduced Vapour Production

Reduced vapour can indicate: low battery charge, degraded coil, improper pod connection, or e-liquid that's too thick. Charge your device, check connections, and ensure you're using appropriate e-liquid viscosity.

Spitting or Popping

Occasional popping is normal, but excessive spitting indicates: overfilled pod, flooded coil, or e-liquid that's too thin. Remove excess liquid, ensure proper fill level, and consider switching to a slightly higher VG ratio.
