Design and Build Quality

The Caliburn G4 Pro has a compact and modern design that combines portability with durability. At Vape Journey, we found the device fits comfortably in hand or pocket. Its lightweight aluminum body has a smooth matte finish, making it resistant to scratches and daily wear.

The ergonomic design ensures comfortable vaping sessions, even for extended periods. The device’s rectangular shape with rounded edges allows a secure grip, while its compact footprint makes it ideal for on-the-go vaping without feeling bulky.

Another feature worth noting is its premium construction quality. Unlike many pod kits in its category, the G4 Pro feels solid, well-assembled, and premium. It is designed to last, even with everyday use.

Understanding the specifications of the device is crucial for making an informed choice. At Vape Journey, we emphasize accurate details, so here’s what we found:

  • Battery: Built-in 1800 mAh battery, providing all-day power without frequent recharging.
  • Max Output Power: Adjustable up to 35 W, allowing for flexibility in vaping styles.

These specifications confirm the G4 Pro as a high-quality pod kit. It balances performance, convenience, and style while remaining compact enough for daily use.

Key Features

The Caliburn G4 Pro stands out in the market due to its rich set of features:

  • Touchscreen Interface: The full touchscreen makes navigating menus, adjusting wattage, and monitoring battery straightforward. At Vape Journey, we observed that even first-time users can operate the device intuitively.
  • Adjustable Airflow: A stepless airflow slider allows users to fine-tune draw tightness. This feature is essential for switching between MTL and restricted DTL vaping styles.
  • GPP Mesh-Coil Pods: Proprietary pods deliver smooth, consistent flavor with minimal maintenance. Mesh coils provide a larger surface area, enhancing vapor production and taste.
  • Multiple Power Modes: With “Waves,” “Storm,” and “Custom” modes, users can experiment with flavor intensity, vapor density, and heat.
  • Long-Lasting Battery: The 1800 mAh battery is sufficient for all-day use, even for moderate vapers.
  • Anti-Leak Pod Design: Refillable pods reduce mess and simplify maintenance.
  • Compact and Portable: Lightweight and ergonomic, ideal for daily carry.

At Vape Journey, these features make the G4 Pro suitable for both new and experienced vapers looking for a reliable and flexible device.

Flavor Performance

Flavor is one of the most important aspects of any vaping device. The G4 Pro’s mesh-coil pods excel at delivering clean, rich, and consistent flavor. At Vape Journey, we tested various e-liquids, including nicotine salts, fruity blends, menthol, and dessert flavors. In each case, the G4 Pro maintained clarity and intensity, highlighting the strength of the mesh-coil system.

Adjustable airflow and power modes allow users to fine-tune the flavor experience. For a tighter, flavor-focused draw, the MTL setting is ideal. For a more open draw and slightly bigger vapor clouds, restricted DTL airflow works best.

It’s important to note that actual flavor experience varies based on e-liquid type, coil resistance, and personal vaping habits. At Vape Journey, we recommend experimenting with both airflow and wattage to find the best combination for your preferred flavor profile.

Vapor Production and Draw

The Caliburn G4 Pro provides balanced vapor output. It does not produce massive clouds like high-wattage mods but is perfect for users who value flavor over cloud size. At Vape Journey, we found the vapor to be smooth, warm, and consistent, even at higher power settings.

The stepless airflow and adjustable wattage allow users to control the draw — tight for a mouth-to-lung hit or looser for restricted DTL vaping. The device maintains stable performance without spitting or overheating when pods are properly primed.

Battery Life and Charging

Battery performance is crucial for pod kits, and the G4 Pro does not disappoint. Its 1800 mAh built-in battery can last a full day for most users, depending on usage habits. The USB-C fast-charging port allows quick recharges, minimizing downtime.

For heavier users, having a portable charger or extra pods is a good idea, but at Vape Journey, we found that moderate daily vaping rarely requires mid-day charging.

Ease of Use and Maintenance

The Caliburn G4 Pro is designed to be beginner-friendly, while still offering customization for advanced users:

  • Pod Replacement: The refillable GPP pods are anti-leak and easy to replace.
  • Touchscreen Interface: Intuitive and simple, even for new vapers.
  • Airflow Control: Allows users to fine-tune the draw with minimal effort.
  • Maintenance: Simple cleaning of pod connection points and occasional wipe-down keeps the device performing optimally.

At Vape Journey, we noticed that these features make the G4 Pro easy to maintain without sacrificing performance.

  3. Keep e-liquid above minimum fill lines to avoid dry hits.
  4. Clean pod connection points occasionally to ensure consistent flavor.
