Quick Verdict: Which One Should You Buy?
Buy the Uwell Caliburn G5 if you want the newer, more premium Caliburn with a 1600mAh battery, GPP Alpha pod support, longer pod lifespan, and a more immersive screen experience.
Buy the Uwell Caliburn G4 if you want a lighter pod system with stronger airflow control, two vaping modes, and a more agile daily-carry feel.
The simple answer: G5 is better for endurance and long-term flavour consistency. G4 is better for portability and draw control.

Design and In-Hand Feel
The Caliburn G4 feels lighter and easier to carry. At approximately 54.7g, it suits users who want a pod system that disappears in the pocket and stays comfortable during a full day of use.
The Caliburn G5 feels more substantial at 65g. That extra weight supports its larger 1600mAh battery and more premium device experience. It feels less like a minimal pod system and more like a flagship daily device.
Practical takeaway: choose G4 if pocket comfort matters most. Choose G5 if you want a richer, more premium in-hand feel.
Flavour Performance: G4 Control vs G5 Consistency
The Caliburn G4 focuses on flavour control. It includes Storm Mode for a stronger first draw and Waves Mode for a smoother, steadier puff. This makes the G4 a strong option for users who like adjusting how their vape feels.
The Caliburn G5 focuses on flavour stability over time. Its GPP Alpha Pods are designed for longer pod life, more stable flavour, and repeated refills without fast flavour drop-off.
This is the biggest difference between the two devices. The G4 gives you more control over the draw. The G5 gives you more confidence that the flavour will stay consistent for longer.
Airflow and Draw Control
The Caliburn G4 gives you three airflow adjustment options: slide the airflow valve, rotate the cartridge orientation, or combine both methods. That makes it better for users who know whether they prefer a tighter MTL draw or a more open RDL-style pull.
The Caliburn G5 is more convenience-focused. Its Smart Triple-Tap control lets you switch output mode, UI, or brightness quickly. Instead of making airflow the main feature, the G5 makes daily interaction smoother.
If you are still deciding between MTL, DL, RDL, and RDTL styles, read ICONA VAPE’s MTL, DL, RDL and RDTL vaping guide before choosing your device.
Battery Life and Daily Reliability
The Caliburn G4 uses a 1300mAh battery, which is already strong for a refillable pod system. For moderate users, it is enough for regular daily use.
The Caliburn G5 increases battery capacity to 1600mAh. That extra 300mAh matters most for heavier users, commuters, and buyers who vape frequently during the day.
Both devices reach up to 35W output, so the G5 does not win because it is more powerful. It wins because it gives you more battery capacity behind the same maximum output.
Practical takeaway: if battery anxiety matters more than weight, the G5 is the better daily device.
Pod Compatibility and Long-Term Use
The Caliburn G4 supports Uwell Caliburn GPP Cartridges, including 0.4Ω, 0.6Ω, 0.9Ω, and 1.2Ω options. This gives users flexibility across different draw styles and nicotine strengths.
The Caliburn G5 supports GPP Alpha cartridges, standard GPP cartridges, and G3 cartridges within the G Pod Platform ecosystem. That gives the G5 a stronger long-term compatibility story, especially for buyers who want newer pods without losing access to the broader Uwell pod ecosystem.
For buyers in Pakistan, pod availability matters almost as much as the device itself. A pod kit only stays useful if replacement cartridges remain easy to find. Both devices are strong here, but the G5 has the advantage because it supports the newer Alpha pod system.
Which One Is Better for Nicotine Salts?
Both the Caliburn G4 and G5 work well with nicotine salts when paired with the right pod resistance. Higher-resistance pods usually suit tighter, smoother nicotine salt use, while lower-resistance pods create a warmer and more open draw.
The G4 gives more airflow tuning, which helps users adjust throat hit and draw tightness. The G5 gives stronger pod longevity and battery life, which helps users who refill often and want flavour to stay consistent.

Which One Is Better for Beginners?
The Caliburn G4 is beginner-friendly if you want a lighter device and do not mind learning basic airflow adjustment. It gives enough control to grow into without becoming complicated.
The Caliburn G5 is better for beginners who want a more complete device from day one. The larger battery, longer pod lifespan, and Smart Triple-Tap control make it feel more future-proof.
If you are switching from disposable vapes and want something reliable for daily use, the G5 is the safer recommendation. If you want lighter carry and more airflow control, the G4 is still a strong choice.
Buy the Caliburn G4 If You Want
- A lighter pod system for daily carry.
- More airflow adjustment options.

- Strong 35W performance without extra size.
- A more technical, tuning-friendly Caliburn experience.

- A larger 1600mAh battery for longer daily use.
- GPP Alpha pod technology with longer pod lifespan.
- More stable flavour across repeated refills.

Authenticity, Warranty, and Buying in Pakistan
Both devices are available through ICONA VAPE’s Uwell Pakistan collection. Every Uwell device sold by ICONA VAPE is authentic and comes with a 3-month warranty, which matters when buying vape hardware online in Pakistan.
If you are comparing total ownership cost, check both device price and pod availability. A slightly better device becomes frustrating if replacement pods are difficult to find. That is why the G5’s GPP Alpha and GPP compatibility gives it a stronger long-term advantage.
Final Recommendation
The Uwell Caliburn G4 is the better choice for users who value control, airflow tuning, and lighter carry. It feels agile, precise, and practical for buyers who like adjusting their vape to match their preference.
The Uwell Caliburn G5 is the better choice for users who want a more premium daily device. Its 1600mAh battery, GPP Alpha cartridge system, longer pod lifespan, and immersive UI make it the stronger option for heavy users and anyone who wants flavour consistency over time.
For most buyers in Pakistan choosing between the two today, the safer long-term recommendation is the Caliburn G5. The Caliburn G4 still makes excellent sense if you care more about lighter carry and airflow control than battery size and pod longevity.
