UWELL Caliburn G4 Pro Koko Pod Kit

Uwell Caliburn G4 Pro KOKO Pod Kit [CRC]: The G4 Pro KOKO is the high-performance, square-form factor flagship of the Caliburn KOKO series. This "Pro" iteration breaks away from previous KOKO models by introducing a massive, full-screen digital interface—the first of its kind in the KOKO lineup. Powered by a high-density 1250mAh battery and capable of reaching 35W, it is engineered to handle everything from tight MTL to intense RDL vaping. With its premium metallic chassis and futuristic aesthetic, the G4 Pro KOKO combines the iconic pocket-friendly KOKO shape with the most advanced power management system Uwell has ever placed in a pod system.

KOKO Evolution: G4 Pro KOKO vs. Previous Generations

The G4 Pro KOKO moves the series into a "Pro" category with several hardware firsts:

• Maximum Power: At 35W, this is the most powerful KOKO ever, designed specifically to maximize the performance of the 0.4 ohm G-series pods.
• Battery Capacity: The 1250mAh battery is a significant upgrade over the G3 KOKO (900mAh), rivaling the endurance of much larger pod-mods.
• Visual Experience: Unlike previous KOKO models that relied on simple LEDs, the G4 Pro features a full-front digital display that tracks battery percentage, wattage, and puff data.
• Stepless Airflow: Includes a dedicated side-slider for minute airflow adjustments, moving away from the "rotate-pod" airflow used in earlier models.

Pod & Coil Compatibility

The G4 Pro KOKO remains the heart of the GPP (G Pod Platform) ecosystem, ensuring users have access to a wide variety of resistance options while introducing newer, high-wattage G4 pods.

Compatible Pods (YES):

• Uwell Caliburn G4 / G4 Pro Replacement Pods: Native pods optimized for the 35W output.
• Uwell Caliburn G3 / GPP Pods: Fully backwards compatible (0.4 ohm, 0.6 ohm, 0.9 ohm, 1.2 ohm).
• G3 Top-Fill & Side-Fill Variants: Both styles fit and fire perfectly in the G4 Pro KOKO.

Incompatible Pods (NO):

• Caliburn KOKO Prime / G2 / Ironfist L Pods: Legacy KOKO pods are physically incompatible.
• Caliburn A-Series (AK2, AK3, AZ3): Entirely different connection and pod shape.

Pro Tip: The G4 Pro KOKO is buttonless for a sleek look. To adjust your wattage, use the touch-sensitive or hidden adjustment controls (refer to the manual for your specific region's interface). Because this device can hit 35W, it is perfect for users who want the vapor production of a large mod in a device that fits in the palm of their hand.

Hardware Maintenance

Given the large digital screen on the G4 Pro KOKO, we recommend using a protective lanyard (usually included) to prevent drop damage to the display. Periodically clean the pod bay with a dry cotton swab to remove condensation and ensure the 3-pin data connection is clear. With 2A fast charging, the device can be fully replenished in under 40 minutes; however, to maintain the high-density battery's health, avoid using "unregulated" high-wattage power supplies over 15W.

Kit Includes: 1 x Caliburn G4 Pro KOKO Device, 1 x 0.4 ohm G4 Refillable Pod (CRC), 1 x 0.9 ohm G4 Refillable Pod (CRC), 1 x Lanyard, 1 x Type-C Cable, and User Manual.

UWELL Caliburn G4 Pro Koko is the Koko-format version of the G4 Pro - a square-bodied refillable pod kit with adjustable airflow and a removable pod. Find more pod systems in our Vape Hardware collection.
