Designed to deliver a smooth and flavorful vaping experience in a sleek, compact frame, this device combines powerful performance, advanced technology, and a user-friendly design. Whether you’re a beginner or a long-time vaping enthusiast, the Caliburn G4 Mini has something to offer everyone.
In this detailed review, we’ll dive deep into everything that makes the UWELL Caliburn G4 Mini Pod Kit a remarkable choice — from its specifications and features to design, colors, compatible pods, and packaging details.
Elegant and Compact Design
The Caliburn G4 Mini continues UWELL’s tradition of minimalistic yet sophisticated design. It’s compact, lightweight, and fits perfectly in your hand or pocket. The device is constructed with a durable aluminum alloy body, ensuring both strength and portability. Its sleek edges and smooth surface provide a premium feel, while its small size makes it ideal for users who prefer discreet vaping.
The device measures approximately 112.7mm × 24.1mm × 14mm and weighs around 46 grams, making it one of the most portable devices in the Caliburn family. Despite its size, it feels solid and comfortable, giving users a perfect balance between portability and performance.
Another highlight is the clear-view e-liquid window. It allows users to easily check their vape juice level without removing the pod, ensuring that you never run out of e-liquid mid-session. This practical addition demonstrates UWELL’s commitment to user convenience and thoughtful design.
Powerful Built-In Battery and Output
Inside the small frame of the Caliburn G4 Mini lies a powerful 1100mAh built-in battery, a remarkable capacity for a device of this size. This battery ensures long-lasting vaping sessions throughout the day, reducing the need for frequent recharging.
The device offers a maximum output of 35 watts, providing flexibility to enjoy both mouth-to-lung (MTL) and restricted direct-lung (RDL) vaping styles. Whether you enjoy a tight, cigarette-like draw or prefer slightly airier hits, the Caliburn G4 Mini adjusts effortlessly to your preference.
Charging is made fast and efficient with the USB Type-C port, allowing quick top-ups in under an hour. A single charge can comfortably last an average user an entire day, depending on usage frequency and power level.
Flavour Excellence with PRO-FOCS 4.0 Technology
UWELL is well-known for its PRO-FOCS flavor technology, and the Caliburn G4 Mini takes it even further with the PRO-FOCS 4.0 system. This latest advancement enhances flavor by up to 35% compared to earlier Caliburn models. It ensures every puff delivers rich, consistent, and authentic taste from your favorite e-liquids.
This innovative system works by controlling the temperature precisely, preventing overheating and burnt hits. It also maintains the original flavor integrity of the vape juice, delivering clean and pure vapor production every time. Whether you’re using freebase nicotine or nic salts, the Caliburn G4 Mini produces satisfying clouds without compromising flavor quality.
Smart Airflow Adjustment for Custom Experience
The Caliburn G4 Mini offers one of the most versatile airflow adjustment systems in its category. The dual airflow design allows users to switch between tighter and looser draws with ease.
By rotating the cartridge or adjusting the airflow slider on the side, you can fine-tune your vaping experience to match your personal preference. This intelligent system gives you complete control over your vaping style — from a smooth, tight MTL draw to a slightly open, flavorful RDL draw.
This flexibility is ideal for those transitioning from smoking to vaping, as it can closely mimic the sensation of traditional cigarettes while offering a cleaner, more enjoyable experience.
Upgraded Cartridge and Leak-Resistant Technology
UWELL has designed the Caliburn G4 Mini with U² leak-resistant technology, combining ultrasonic welding and a U-shaped airflow channel to minimize leakage and condensation. This innovation ensures that your vape stays clean and efficient, eliminating the common frustration of messy pods.
The Caliburn G4 Mini is compatible with CALIBURN GPP cartridges, offering excellent versatility. These pods are designed for smooth vapor delivery and consistent performance. The ergonomic mouthpiece provides a comfortable fit for extended vaping sessions, while the top-fill design makes refilling simple and mess-free.
Additionally, these cartridges feature an anti-condensation structure that prevents moisture buildup, helping to extend the life of your pod and maintain consistent performance.
