Premium Design and Build Quality

Compact and Stylish KOKO Design

The Caliburn G4 Pro Koko keeps the iconic square-shaped KOKO appearance while introducing a more refined and premium look. Unlike traditional pen-style pod systems, this compact structure feels more ergonomic and portable.

Its lightweight body allows users to carry the device comfortably in pockets or bags. Furthermore, the smooth curved edges improve grip and overall comfort during long vaping sessions.

High-Quality Materials

Uwell uses durable aluminum alloy construction to give the device a premium feel without adding unnecessary weight. As a result, the pod kit feels sturdy and reliable for daily use.

The device also comes in multiple stylish color options, allowing users to choose a finish that matches their personal style.

Large Battery for All-Day Vaping

Powerful 2000mAh Built-In Battery

Battery performance is one of the biggest highlights of the Uwell Caliburn G4 Pro Koko Pod Kit. The device includes a massive 2000mAh built-in battery that easily supports extended vaping sessions.

Many compact pod systems require frequent charging throughout the day. However, this device delivers longer battery life, which makes it ideal for heavy users and travelers.

Fast USB Type-C Charging

Uwell also includes fast USB Type-C charging support. Therefore, users can recharge the device quickly and reduce downtime significantly.

Fast charging becomes especially useful for users who rely on their pod kit throughout the entire day.

Smart Touchscreen Interface

Large HD Display

One of the most unique features of the Caliburn G4 Pro Koko is its large HD touchscreen display. Unlike basic pod systems with simple LED indicators, this device provides a fully interactive interface.

The screen allows users to monitor important information quickly and easily.

Easy Navigation and Controls

The touchscreen interface gives users access to:

• Wattage adjustment
• Battery percentage
• Puff counter
• Vaping modes
• Screen brightness
• UI customization settings

Additionally, the responsive controls make navigation smooth and beginner-friendly.

Adjustable Power Output

Up to 35W Performance

The Caliburn G4 Pro Koko offers adjustable power output up to 35 watts. Because of this flexibility, users can customize vapor production and flavor intensity according to their preferences.

Lower wattages work well for smooth MTL vaping, while higher wattages create warmer and denser vapor for RDL vaping.

Smooth and Consistent Delivery

The device maintains stable power delivery during daily use. Consequently, users enjoy consistent flavor and vapor production from the first puff to the last.

This reliable performance helps improve the overall vaping experience.

Multiple Vaping Modes

Storm Mode

Storm Mode increases output intensity for stronger throat hits and faster vapor production. Therefore, this mode works best for users who prefer bold flavor and dense clouds.

Waves Mode

Waves Mode focuses on balanced and smooth performance. It delivers steady flavor consistency while creating a softer vaping experience.

Many users prefer this setting for regular all-day vaping.

Customize Mode

Customize Mode allows users to personalize device settings according to their preferences. As a result, experienced users gain more control over their vaping experience.

Exceptional Flavor Quality

Pro-FOCS Flavor Technology

Flavor quality remains one of the strongest features of the Caliburn lineup. Fortunately, the G4 Pro Koko continues this tradition with upgraded Pro-FOCS flavor technology.

This system improves:

• Flavor consistency
• Vapor smoothness
• Coil efficiency
• E-liquid utilization

As a result, users experience richer and cleaner flavor from their favorite e-liquids.

Suitable for Nicotine Salts and Freebase E-Liquid

The device works well with both nicotine salt and freebase e-liquids. Therefore, users can easily choose the vaping style that suits them best.

Nicotine salts provide smoother throat hits at higher nicotine strengths, while freebase e-liquid delivers stronger vapor production.

Improved Anti-Leak Technology

Cleaner Vaping Experience

Leaking remains a common issue in many pod systems. However, Uwell addresses this problem with upgraded anti-leak technology in the Caliburn G4 Pro Koko.

The improved cartridge structure helps reduce condensation and minimizes e-liquid leakage during daily use.

Convenient Refilling

The refill system also makes the process easier and cleaner. Consequently, users can refill pods quickly without creating unnecessary mess.

This convenience becomes especially valuable for beginners.

Pod Compatibility and Coil Options

Wide Pod Compatibility

Another major advantage of this pod kit is its broad compatibility with different Caliburn pods.

The device supports:

• Caliburn GPP Pods
• Upgraded GPP cartridges
• Caliburn G3 Pods

Because of this flexibility, users can experiment with different resistances and vaping styles more easily.

MTL and RDL Support

Different pod options allow the device to support both MTL and RDL vaping styles.

MTL vaping creates a tighter draw that closely resembles traditional cigarettes. On the other hand, RDL vaping provides a looser airflow and increased vapor production.

Airflow Adjustment System

Personalized Draw Resistance

The adjustable airflow system allows users to customize draw resistance according to their preferences.

Users who enjoy tighter draws can reduce airflow for a cigarette-like experience. Meanwhile, users who prefer larger clouds can increase airflow for smoother and airier pulls.

Better Overall Control

This airflow flexibility improves versatility and helps the device suit a wider variety of vaping styles.

As a result, both beginners and experienced users can enjoy comfortable performance.

Daily Performance and User Experience

Reliable Everyday Device

The Caliburn G4 Pro Koko performs consistently throughout daily use. The combination of long battery life, responsive controls, and stable output makes the device highly dependable.

Users can comfortably use the pod kit during work, travel, or casual outings without worrying about constant charging.

Beginner-Friendly Features

Although the device includes advanced customization options, the overall interface remains simple to understand.

New users can start vaping quickly, while experienced users can explore additional settings and modes.
