Uwell Caliburn G4 PRO KOKO Pod System Review
Get ready vapers, because the Uwell Caliburn G4 PRO KOKO Pod System represents a major pod-based transformation that brings high-end capabilities into a very familiar Caliburn series square silhouette. Basically, you’re looking at an open pod system that totally reimagines what a compact device can do. It focuses on providing a substantial feel and deep technical functions, minus the heavy bulk of a traditional mod. Respecting its heritage but looks firmly toward the future of hardware.
A Masterpiece in Terms of Industrial Design and Neat Aesthetic Quality
Uwell’s Caliburn G4 PRO KOKO Pod System chassis is built from a premium aluminum alloy that feels solid and cool in your hand. Now, while it retains the iconic, ergonomically sleek & seamless square shape, this version uses fine materials (the juxtaposition of the matte metal against the cutting-edge technology embedded within it) to provide a luxury standard. Entirely draw-activated too, as the discreet side button is to only turn the power ON/OFF, preventing accidental firing. Oh, and the large front ultra-shatterproof screen adds an amazing layer of modern aesthetics. When the screen comes to life, it contrasts beautifully with the industrial metal, creating a device that looks glorious.
Unprecedented Endurance and Rapid Charging
A massively integrated 2000mAh battery handles a 35-watt max output and can last up to 10 days (when vaping moderately). Even with frequent use, you can get up to 4 days of before needing to recharge. The side Type-C port supports 2.5A fast charging, taking the battery from empty to full in less than 50 minutes.
Picking Your Hit with Intelligent Modes and Adjustable Airflow Control
There are three distinct output modes you can try in order to find your preferred power curve:
- STORM: Sends a quick surge of energy for a faster ramp-up and a warmer pull that mimics a high-wattage tank.
- WAVES: Focuses on stability, maintaining a smooth delivery of power from start to finish.
- CUSTOMIZE: Choose the wattage output manually to dial in your exact intensity.
On the side, a mechanical slider lets you transition between different airflow dynamics, from tight MTL (Mouth-To-Lung) to wide-open DTL (Direct-To-Lung) pulls.
The Touchscreen Revolution
Uwell Caliburn G4 PRO KOKO’s centerpiece is a 2” shatterproof touchscreen – an intuitive interface for your Battery percentage, Wattage, Mode, Puff count and the resistance (Ω) of the coil currently being utilized. Core attributes are accessible with one tap, removing the need for confusing button combinations.
The operating system includes functions rarely found in such a small format, such as five “blind draw” UI themes. You begin with two themes and unlock the remaining three as you hit milestones of 2,000, 10,000, and 20,000 puffs. Plus, there are eight selectable interface languages, and you can even adjust the screen timeout and brightness for better visibility or energy conservation.
A Dual-Platform Pod Ecosystem
Supports two distinct pod platforms, both utilizing U² Anti-Leak Technology to minimize mess during use. These pods use integrated coils to simplify maintenance and connect magnetically with a satisfying click. PRO-FOCS 4.0 is the powerhouse behind the flavor intensity, as it works by controlling the heating temperature to restore the freebase or salt-based nicotine E-Liquid flavor to its original profile. These side-filling pod options are both transparent, PCTG-constructed pods that’re made using ultrasonic welding and have the same clear, comfortable mouthpiece. Caliburn GPP 3mL Pods use stainless steel regular 0.4Ω to 1.2Ω internal coils, while Caliburn G3 Pods come in either 0.6Ω and 0.9Ω that are stainless steel mesh.
