Uwell Caliburn G4 Pro Koko Vape Kit

The Caliburn G4 Pro Koko features four distinct vaping modes, each engineered to deliver a unique experience:

1. Smart Mode: Intelligently adjusts wattage based on coil resistance, optimising flavour and vapour production automatically. Ideal for users seeking a hassle-free experience.
2. Storm Mode: Delivers maximum power output (up to 35W) for intense vapour production and bold flavour delivery. Perfect for experienced vapers seeking aggressive performance.
3. Waves Mode: Cycles through variable wattage levels, creating a dynamic vaping experience that mimics the sensation of different power settings. Offers a unique, evolving draw.
4. Custom Mode: Allows users to manually set precise wattage levels between 5W and 35W, providing complete control for those seeking bespoke performance parameters.

Advanced Battery Technology & Charging

The 2000mAh built-in battery represents a significant capacity upgrade, delivering all-day vaping capability for most users. The battery management system incorporates multiple safety protections including over-discharge prevention, short-circuit protection, and temperature monitoring to ensure safe, reliable operation. USB-C fast charging technology enables rapid battery replenishment—a full charge typically requires approximately 60-90 minutes, depending on power source. The touchscreen display provides precise battery percentage readings, ensuring users always know remaining capacity. This combination of substantial battery capacity and rapid charging makes the Caliburn G4 Pro Koko exceptionally convenient for users with demanding vaping habits.

Adjustable Airflow & Vaping Styles

The integrated airflow adjustment system accommodates both mouth-to-lung (MTL) and restricted direct-to-lung (RDTL) vaping preferences. By adjusting the airflow slider, users can tighten the draw for a cigarette-like MTL experience or open it for a more airy RDTL sensation. This versatility eliminates the need for multiple devices and allows users to experiment with different vaping styles using a single kit. The adjustable airflow works seamlessly across all four vaping modes, providing consistent performance regardless of user preference.

Pod Compatibility & Refillable System

The Caliburn G4 Pro Koko utilises the proven Caliburn G3 pod system, ensuring compatibility with a vast range of refillable pods available in the market. The 2ml pod capacity (compliant with TPD regulations) accommodates most e-liquids, and the straightforward refilling process requires simply removing the silicone stopper, filling via the convenient fill port, and waiting 5-10 minutes for coil saturation. The magnetic pod connection ensures secure attachment and reliable electrical contact. This refillable system eliminates the waste associated with disposable pods whilst offering substantial cost savings over time. Users can experiment with different e-liquid flavours and nicotine strengths without purchasing multiple devices.

Installation and Usage Instructions

Initial Setup

1. Unbox Your Device – Remove the Caliburn G4 Pro Koko from packaging and inspect for any damage.

3. Prepare the Pod – Remove the pre-installed Caliburn G3 pod from the device if desired, or proceed with the included pod.

Pod Filling Process

1. Remove the Pod – Gently pull the pod away from the device. The magnetic connection will release easily.
2. Locate the Fill Port – Find the silicone stopper on the top of the pod.
3. Remove Silicone Stopper – Carefully peel back the silicone stopper to reveal the fill port.
4. Fill with E-Liquid – Using a dropper or e-liquid bottle nozzle, slowly fill the pod with your chosen e-liquid. Avoid overfilling—leave a small air gap at the top.
5. Replace Silicone Stopper – Firmly press the silicone stopper back into place to seal the fill port.
6. Prime the Coil – Allow 5-10 minutes for the e-liquid to saturate the mesh coil before use. This prevents dry hits and ensures optimal flavour.
7. Reinsert Pod – Align the pod with the device and push firmly until the magnetic connection engages with a satisfying click.

1. Power On – Tap the touchscreen twice rapidly to activate the device. The display will illuminate, showing current settings.
2. Select Vaping Mode – Tap the mode icon on the touchscreen to cycle through Smart, Storm, Waves, and Custom modes. The current mode is displayed on screen.
3. Adjust Wattage (Custom Mode Only) – In Custom mode, use the touchscreen to increase or decrease wattage between 5W and 35W. Swipe up to increase, swipe down to decrease.
4. Adjust Airflow – Use the physical airflow slider on the side of the device to tighten (MTL) or open (RDTL) the draw to your preference.
5. Vape – Simply inhale on the mouthpiece to activate the device. The touchscreen displays real-time information including current wattage, puff count, and battery percentage.
6. Monitor Battery – Check the battery icon on the touchscreen regularly. When battery reaches critically low levels, recharge using the USB Type-C cable.
7. Power Off – Tap the touchscreen twice rapidly again to deactivate the device.

Recommended Vaping Technique

For optimal flavour and performance, take slow, controlled draws lasting 2-3 seconds. The adjustable airflow allows customisation—tighten for a cigarette-like MTL draw or open for a more airy RDTL experience. Experiment with different wattage settings and vaping modes to discover your preferred experience.

Frequently Asked Questions

What devices are compatible with Caliburn G3 pods?

The Caliburn G4 Pro Koko is fully compatible with all Caliburn G3 refillable pods, including standard 0.8? mesh coil pods and higher resistance 1.2? variants. This ensures access to a wide range of replacement pod options.

How long does the 2000mAh battery last?

Battery life depends on usage patterns, wattage settings, and vaping frequency. For average users vaping at moderate wattage (15-25W), the 2000mAh battery typically provides 1-2 days of use. Heavy users may require daily charging, whilst light users may achieve 2-3 days between charges.

What e-liquids can I use with this device?

The Caliburn G4 Pro Koko accommodates all e-liquid types including freebase nicotine (any strength) and nicotine salts (typically 10mg-20mg). The device performs optimally with 50/50 VG/PG or 60/40 VG/PG ratios, though higher VG ratios are also compatible.

How do I switch between vaping modes?

Simply tap the mode icon on the touchscreen display to cycle through the four available modes: Smart, Storm, Waves, and Custom. The current mode is clearly displayed on screen. Each mode offers distinct performance characteristics tailored to different vaping preferences.

Is the touchscreen durable?

Yes, the touchscreen utilises scratch-resistant OLED technology designed for durability. However, we recommend using the included silicone protective case to safeguard the screen from impacts and scratches during daily use.

Can I adjust the wattage in all modes?

Manual wattage adjustment is only available in Custom mode, where users can set precise wattage between 5W and 35W. Smart mode automatically adjusts wattage based on coil resistance, whilst Storm and Waves modes use pre-programmed wattage profiles.

How do I know when to replace the pod?

Replace the pod when you experience diminished flavour, reduced vapour production, or a burnt taste. Typical pod lifespan ranges from 1-3 weeks depending on usage frequency, e-liquid type, and wattage settings. The touchscreen displays coil resistance, which may increase as the coil degrades.

Is this device suitable for beginners?

Absolutely. Despite its advanced features, the Caliburn G4 Pro Koko is exceptionally user-friendly. Smart mode automatically optimises performance, eliminating the need for manual adjustments. The intuitive touchscreen interface and straightforward pod refilling process make it ideal for both beginners and experienced vapers.

Does the kit include a charging cable?

Yes, the kit includes a USB Type-C charging cable. However, a wall adapter is not included—users can charge via any USB power source including computer USB ports, wall adapters, or power banks.

What is the difference between MTL and RDTL vaping?

MTL (Mouth-To-Lung) mimics cigarette-style draws—vapour is first drawn into the mouth, then inhaled into the lungs. RDTL (Restricted Direct-To-Lung) allows slightly more airflow, enabling direct inhalation whilst maintaining some restriction. The Caliburn G4 Pro Koko's adjustable airflow accommodates both styles.

Conclusion

The Uwell Caliburn G4 Pro Koko represents a significant leap forward in refillable pod kit technology, seamlessly blending innovative touchscreen controls with exceptional performance capabilities. By combining a powerful 2000mAh battery, variable wattage up to 35W, four distinct vaping modes, and adjustable airflow, this device delivers a truly personalised vaping experience that caters to both novice and experienced users alike.

The 2000mAh battery capacity ensures all-day vaping for most users, whilst USB-C fast charging enables rapid battery replenishment when needed.
