Let’s explore everything this compact yet powerful pod kit has to offer, from its sleek design to its cutting-edge technology and real-world performance.
A Modern, Minimalist Design
The Uwell Caliburn G4 Mini is built around the idea of simplicity and elegance. With dimensions of approximately 112.7mm × 24.1mm × 14mm, it strikes a balance between portability and comfort. You can easily slide it into your pocket, clutch, or even the palm of your hand without feeling any bulk.

The body is crafted from aluminum alloy and durable PCTG materials, giving it a sturdy yet lightweight feel. Its smooth surface resists fingerprints, and the clean edges make it comfortable to hold for long sessions.

This color variety ensures that every user can find a G4 Mini that fits their individual style. Whether you prefer bold, elegant tones or sleek metallic finishes, there’s an option that feels uniquely yours.
Performance and Power: Compact Yet Capable
Don’t let the word “Mini” fool you. The Uwell Caliburn G4 Mini packs serious power and advanced vaping performance inside its small frame. It’s built to deliver smooth draws, rich flavour, and consistent vapor production without any fuss.
PRO-FOCS 4.0 Flavour Technology
At the heart of the G4 Mini lies Uwell’s cutting-edge PRO-FOCS 4.0 flavour technology, which enhances taste quality and maintains the original flavor profile of your e-liquid. This system works by recycling condensed vapor back into the coil, ensuring every puff feels as fresh and flavourful as the first.
The result? Up to 35% better flavour intensity than earlier Caliburn generations. Whether you’re into sweet fruit blends, dessert flavours, or cooling menthols, the G4 Mini brings them to life with impressive accuracy.
Upgraded Pod Compatibility
The G4 Mini uses the new CALIBURN GPP pods, which have been upgraded for greater coil longevity and better heat distribution. These improved cartridges also last around 35% longer than older ones, saving you money and ensuring a more reliable vaping experience.
Even better, the G4 Mini is backward compatible with older Caliburn G3 pods, making it convenient for long-time Uwell users who already have spares on hand. This flexible compatibility is one of the most user-friendly aspects of the G4 Mini system.
Adjustable Airflow for Custom Draws
One of the most remarkable features of the Uwell Caliburn G4 Mini is its dual airflow control system. Users can adjust their airflow in two ways:
- Side airflow control valve – for quick and precise adjustments.
- Cartridge rotation system – simply rotate the pod or insert it in a different orientation to fine-tune your draw.
This dual adjustment method allows both MTL (mouth-to-lung) and RDL (restricted direct lung) vaping styles. Whether you enjoy a tight, cigarette-like pull or a looser, airier inhale, the G4 Mini adapts to your preference.
Battery and Output Power
Despite its small size, the Uwell Caliburn G4 Mini comes equipped with an 1100mAh internal battery, providing excellent endurance for all-day vaping. You can enjoy consistent output without worrying about frequent recharges.
The device supports a maximum output of 35W, giving you a powerful performance and fast ramp-up time. Whether you’re chasing flavour or a bit of vapor density, it handles both exceptionally well.
Charging is handled via a USB-C port, ensuring quick and reliable recharging. Just a short charge and you’re ready to go again, making it perfect for users who need a dependable daily vape.
Leak-Resistant Engineering
Leaking pods are one of the most common frustrations for vapers, but the G4 Mini tackles this problem with Uwell’s advanced U² technology. This combines ultrasonic welding and a U-shaped internal airflow design, effectively minimizing leaks and preventing condensation buildup.
This improved construction not only keeps your device cleaner but also enhances the durability of the pod and maintains consistent airflow. It’s a small detail that makes a big difference in daily use.

While it’s a minimalist package, it includes the essentials to get started. For best performance, always allow the coil to soak (prime) for several minutes before your first puff. This helps the cotton fully absorb e-liquid and prevents burning.
Ease of Use and User Experience
The Uwell Caliburn G4 Mini is all about simplicity and efficiency. There are no buttons, menus, or confusing modes—just inhale to activate. The draw-activated firing system is responsive and consistent, giving you instant vapor whenever you want it.

The transparent e-liquid window is another small but incredibly useful feature. You’ll always know exactly when it’s time to refill, helping you avoid dry hits or coil damage.
Tips for Getting the Best Performance
To make the most of your Uwell Caliburn G4 Mini, keep these expert tips in mind:
- Prime your coil: Let the pod sit for at least 5 minutes after filling to allow the coil to saturate.
- Adjust airflow: Try different airflow settings until you find your ideal draw tightness.
- Monitor battery levels: Recharge when the LED turns red to maintain strong vapor output.
- Keep it clean: Regularly wipe the connection points and the inside of the pod cavity to prevent residue buildup.
- Use compatible pods: Stick to official Uwell GPP pods for the best performance and leak prevention.
- Avoid overfilling: Fill only up to the marked line to avoid leaks and flooding.
By following these steps, you’ll get smoother, richer, and longer-lasting performance from your G4 Mini.
