Uwell has a knack for taking something brilliant and refining it until it is near-perfection. The Caliburn KOKO series has long been the “cool younger sibling” of the standard Caliburn sticks—more compact, more stylish, and arguably more pocket-friendly. With the arrival of the Uwell Caliburn G5 KOKO, the brand hasn’t just iterated; they have genuinely raised the bar for what a palm-sized vape can do.
Design and Build Quality
First off, the G5 KOKO feels incredibly premium in the hand. It retains that iconic square silhouette but introduces a more rugged, “cyber-industrial” aesthetic. Made from a high-grade aluminium alloy, it is remarkably light but doesn’t feel like a toy. It has that “heft of quality” you want from a device you will be carrying everywhere.
The lanyard loop is still there, making it a dandy choice for those of us who tend to misplace our vapes. The finish is also noticeably more fingerprint-resistant than previous models, keeping it looking sharp even after a full day of use in the city.
Performance and Flavour
The real magic happens under the bonnet. Uwell‘s Pro-FOCS flavour technology is present and accounted for, and it is as impressive as ever. Whether you are running a punchy 20mg nic salt or a 50/50 freebase juice, the flavour clarity is spot on. The G5 KOKO handles the 0.6Ω pods beautifully for a restricted direct-to-lung (RDL) hit, providing surprisingly dense vapour for such a small unit.

Key Features Breakdown
The OLED Screen and Interface
A massive upgrade here is the OLED display tucked neatly into the side. It is bright enough to read even when the British sun decides to make a rare appearance. It displays your battery percentage, puff count, and current wattage. The Smart Mode is a brilliant touch for beginners—it reads the resistance of your pod and automatically sets the optimum wattage, so you don’t accidentally singe your coil.
Battery Life and Charging
With a 1200mAh battery, this thing is a proper workhorse. If you are a moderate vaper, you will easily get two days out of a single charge. When you do run low, the 2A Type-C fast charging is a lifesaver, taking the device from “dead as a dodo” to 80% in roughly 20 minutes.
Final Words
The Uwell Caliburn G5 KOKO is a cracking bit of kit. It is sturdy, the flavour is top-tier, and the increased battery capacity solves the only real gripe vapers had with earlier KOKO models. It is simple enough for a novice but has enough “grunt” to satisfy a seasoned hobbyist.
FAQ
1. Can I use the old Caliburn G2 coils in the G5 KOKO?
No, the G5 KOKO is designed to use the newer integrated pod cartridges. This design is much better at preventing leaks compared to the older replaceable coil systems.
2. How long do the G5 pods typically last?
Depending on how sweet your e-liquid is, you can usually expect a pod to last between 10 to 14 days. If you notice a burnt taste, it’s time to swap it for a fresh one.
3. Is this kit suitable for high VG e-liquids?
While you can use 70/30 VG/PG juices with the 0.4Ω pod, the G5 KOKO is truly at its best with 50/50 ratios. High VG liquids may struggle to wick quickly enough during “chain vaping”.
4. What does the ‘Smart Mode’ actually do?
Smart Mode is a safety feature. It detects the resistance of the pod you have inserted and caps the wattage range. This prevents you from accidentally pumping 30W into a 0.9Ω pod and ruining it instantly.
5. How do I know when the battery is fully charged?
The OLED screen will show a clear battery icon and percentage. Once it reaches 100%, you are good to go. Overcharging protection is built-in for your peace of mind.
