The Uwell Caliburn series has long set the standard for quality pod systems. With each generation, Uwell improves performance, flavor, and design to meet modern vapers’ expectations. The Uwell Caliburn G4 Pro continues this legacy and pushes boundaries further than ever before. It’s not just an upgraded pod kit—it’s a complete reinvention of what a portable vape can do.
With its intelligent touchscreen interface, upgraded GPP pod platform, enhanced leak-proof technology, and refined flavor system, the G4 Pro blends innovation with simplicity. Whether you’re a casual vaper or a flavor chaser, this kit offers something extraordinary.
Let’s explore what makes the Caliburn G4 Pro a next-generation pod device worth your attention.
A Revolution in the Caliburn Line
Uwell’s Caliburn family is famous for reliability, clean taste, and ergonomic design. The G4 Pro carries that DNA but transforms the user experience through technology. This model introduces a full-touch 2.51-inch screen, a first in the Caliburn lineup.
Every interaction—from adjusting wattage to monitoring battery life—happens on the smooth touchscreen. Gone are the traditional buttons. With a single tap, you can change settings, check puff counts, or switch modes. It feels futuristic yet intuitive.
The screen even supports multiple languages and customizable UI themes, so users can personalize their device to match their style.
Premium Design and Build Quality
The G4 Pro’s exterior immediately signals quality. Its aluminum alloy frame offers a perfect balance of lightness and durability. The body feels solid yet comfortable in the hand, with gentle curves that enhance grip during daily use.
The minimalist design highlights its vibrant color finishes, which include:
- Ink Blue
- Light Green
- Fantasy Pink
- Desert Gold
- Stripe Black
- Iron Gray
- Pearl Silver
- Frost White
Each color option reflects Uwell’s focus on aesthetic appeal. The device’s sleek chassis complements its advanced inner technology, creating a perfect blend of beauty and performance.
A new droplet-shaped e-liquid window on the side adds practicality. You can instantly check your juice level without removing the pod, avoiding dry hits and overfilling.
Touchscreen Technology: A First for Uwell Pods
The Caliburn G4 Pro stands out for its 2.51-inch full touchscreen display, offering the smoothest user interface ever seen in a pod system. The high-definition screen provides instant access to all vital information—battery level, puff count, wattage, and more.
Instead of pressing multiple buttons, users now navigate settings with intuitive swipes and taps. The screen includes a simple home layout featuring:
- Wattage control
- Puff counter reset
- Mode selection
- Brightness adjustment
- Battery saver option
It even allows you to rename the device or change interface themes. Uwell included six themes (three preloaded and three unlockable as you vape). This gamified design rewards regular use and adds a fun, personal touch.
The responsive interface ensures precise control and faster operation. It’s the perfect combination of convenience and style.
Battery Power and Charging
Power is another area where the G4 Pro shines. It houses an impressive 1800 mAh built-in battery, delivering long-lasting performance throughout the day. Whether you’re working, traveling, or relaxing, the device keeps up effortlessly.
The maximum output reaches 35 watts, providing ample power for both mouth-to-lung (MTL) and restricted direct-lung (RDL) vaping styles. You can tailor wattage directly through the touchscreen—simple, fast, and efficient.
Charging is equally convenient thanks to USB-C fast charging. A full charge takes roughly 45 minutes, and the Type-C port ensures a stable, safe current flow. This combination of capacity and efficiency means less downtime and more vaping.
GPP Pod Platform Compatibility
The Uwell Caliburn G4 Pro uses the new GPP pod platform, which stands for “G Pod Platform.” The key advantage of this platform is its cross-compatibility with previous Caliburn G-series cartridges. If you’ve used older models like the Caliburn G3, you can use many of those pods interchangeably.
Each GPP cartridge holds 3 mL of e-liquid, providing ample capacity for daily use. The side-fill system allows easy and mess-free refilling. You don’t need to remove the pod—just open the silicone plug, fill your favorite e-juice, and close it securely.
The magnetic pod connection ensures a snug, leak-free fit. Pods click into place easily and stay secure during transport.
This compatibility makes the G4 Pro an excellent choice for existing Caliburn users who want to upgrade without replacing their entire setup.
Coil Options for Every Style
Uwell designed the G4 Pro to satisfy different vaping preferences. The kit includes two coils:
- 0.4 Ω GPP mesh coil for richer flavor and denser vapor.
- 0.6 Ω GPP mesh coil for a smoother, balanced draw.
The 0.4 Ω coil works best for RDL vaping, producing warmer vapor and a more intense throat hit. The 0.6 Ω coil, on the other hand, is ideal for MTL vapers who prefer tighter airflow and a cigarette-like experience.
Both coils use Uwell’s PRO-FOCS 4.0 flavor technology, which fine-tunes airflow and heating to maximize taste. Each puff feels clean, consistent, and flavorful—hallmarks of the Caliburn brand.
Enhanced Airflow Control
The Caliburn G4 Pro introduces a refined stepless airflow system that offers incredible precision. You can adjust the airflow using a physical slider or by rotating the pod orientation inside the device. This dual-control design makes switching between MTL and RDL draws effortless.
Tighten the airflow for a restricted inhale that mimics smoking, or open it up for a looser, cloudier experience. Every adjustment feels smooth and responsive.
This feature is especially valuable for users who enjoy experimenting with different vaping styles or e-liquid types.
Leak Resistance and Durability
Nothing ruins a vaping session faster than e-liquid leaks. Uwell tackles this issue with advanced engineering. The G4 Pro cartridges feature U² Leak-Resistance Technology, which combines ultrasonic welding with a U-shaped internal structure. This design channels condensation back toward the coil instead of letting it escape through airflow holes.
The result is a cleaner experience with fewer leaks, minimal condensation, and better hygiene. This leak-proof innovation also extends coil lifespan, ensuring consistent performance even after long-term use.
Flavour That Redefines Expectations
Uwell is famous for its PRO-FOCS flavor optimization system, and version 4.0 sets a new benchmark. This technology recycles drawn air through the coil, enhancing the richness and depth of each puff. It balances temperature and airflow to preserve delicate flavor notes.
No burnt taste, no muted output—just pure, consistent satisfaction. Whether you enjoy fruit, dessert, tobacco, or menthol e-liquids, the G4 Pro delivers crisp and authentic flavor.
Combined with the mesh coil structure, this system ensures even heating, quick ramp-up, and a dense, aromatic vapor.
Vaping Modes: Storm, Waves, and Custom
The Caliburn G4 Pro offers three distinct vaping modes that let users control their experience like never before:
1. Storm Mode
Designed for maximum performance, this mode unleashes the full power of the device. Expect intense flavor and large vapor production. Perfect for high-VG liquids and RDL vaping.
2. Waves Mode
This mode delivers smoother, more stable vapor output. It’s ideal for consistent flavor delivery during long sessions, balancing power and comfort.
3. Custom Mode
Here’s where the G4 Pro truly stands out. Custom mode lets users program wattage behavior throughout a single puff—higher at the start, lower in the middle, or reverse. It gives fine control over throat hit, warmth, and flavor intensity.
This level of customization is rarely seen in compact pod systems, and it elevates the G4 Pro above most of its competitors.
Smart UI and Extra Functions
The touchscreen isn’t just pretty—it’s packed with intelligent functionality. Beyond theme and mode control, it includes:
- Puff counter and reset option
- Battery saver mode
- Brightness adjustment
- Multilingual support (8 languages)
- Device renaming feature
These thoughtful touches show Uwell’s dedication to user experience. Every feature serves a purpose and enhances daily usability.
What’s Inside the Box
Each Caliburn G4 Pro kit includes everything you need to start vaping right away:
- 1 × Caliburn G4 Pro Device
- 1 × GPP 0.4 Ω Pod Cartridge
- 1 × GPP 0.6 Ω Pod Cartridge
- 1 × User Manual
- 1 × Warranty Card
The inclusion of two coil resistances means you can immediately experiment with different vape styles. The clear instructions and durable packaging reflect Uwell’s attention to detail.
Ease of Use
Despite its advanced technology, the Caliburn G4 Pro remains extremely user-friendly. The draw-activation system ensures instant firing with no delay. Just inhale, and the device responds immediately.
The touchscreen interface eliminates guesswork. Even beginners can navigate menus, change modes, and view battery status within minutes. The pod clicks securely in place, and refilling is straightforward.
Every element of the G4 Pro’s design focuses on simplicity without sacrificing sophistication.
Maintenance and Longevity Tips
To maintain the best performance:
- Always prime new coils before first use.
- Keep the pod at least half full to prevent dry hits.
- Clean the device regularly, especially around the pod contacts.
- Avoid overcharging the battery—unplug once it’s full.
- Replace coils when flavor starts fading or vapor production drops.
Following these steps will keep your G4 Pro running smoothly for months.
