Uwell Caliburn Koko Prime Kit Review Stylish, Compact, and Flavorful
The Uwell Caliburn Koko Prime Kit is the upgraded version of the original Caliburn KOKO, and it has already become one of the most popular devices in the Caliburn family. Powered by a 690mAh rechargeable battery, equipped with a 2mL refillable pod, and fully compatible with the Caliburn G coils and pods, this kit delivers excellent flavor, smooth vapor, and reliable performance in a stylish, pocket-friendly design.
If you’re in Dubai or anywhere in the UAE looking for a compact pod system that balances design, portability, and performance, the Caliburn Koko Prime is definitely worth considering.
Build Quality & Design
The Caliburn Koko Prime keeps the same compact form factor as its predecessor but takes things up a notch with a modern, customizable design. Measuring 68mm × 45.6mm × 16mm and weighing only 48g, it’s lightweight yet sturdy thanks to its zinc-alloy chassis.
One of its coolest features is the interchangeable magnetic side panels, allowing you to swap colors and personalize your device. The slogan “Keep On Keeping On” is hidden on the backside, giving it a stylish touch.
For added convenience, there’s a lanyard attachment point at the top, and Uwell even includes a graffiti-styled lanyard in the box making it both practical and trendy for on-the-go vaping.

Getting Started with the Koko Prime
Using the Koko Prime Kit is super beginner-friendly. The pod clicks securely into the device and has side windows for easy juice monitoring. It holds up to 2mL of e-liquid.
To set up:
Remove the pre-installed coil.
Prime the coil by adding a few drops of e-liquid.
Insert the coil back into the pod.
Fill the pod through the top-fill silicone valve.
Snap it into place and you’re ready to vape.
The pod can be rotated to adjust airflow:
Loose MTL: Insert pod with airflow holes close together.
Tight MTL: Insert pod with airflow holes apart.
Coils & Performance
The Koko Prime uses replaceable Caliburn G coils:
1.0Ω FeCrAl coil – perfect for classic MTL vaping with a smooth throat hit.
0.8Ω mesh coil – provides a warmer vape with more vapor, ideal for restrictive DL.
Using Uwell’s Pro-FOCS flavor testing technology, the Koko Prime consistently delivers rich, clean, and satisfying flavor. It works especially well with nicotine salts, giving a strong yet smooth throat hit.
During testing, the coil life was impressive. One coil lasted through 11 refills before needing replacement, with no leaking or dry hits even during chain vaping.
Battery Life & Charging
The 690mAh integrated battery delivers reliable power throughout the day. Depending on usage, it can last through a pod and a half of juice before needing a recharge. Charging is quick and convenient via Type-C, taking just 40–45 minutes to fully recharge.
The only downside: it doesn’t support pass-through vaping (using while charging). Still, its fast charge time makes up for it.
