First Impressions of the Caliburn G3 Pro Koko
Look & Feel
Right out of the box, the G3 Pro Koko feels like a mini flagship device. The compact, square shape makes it pocket-friendly, and the glossy finish gives it some upscale flair. But the real star is the 1.8" TFT screen—it’s bright, colourful, and even lets you customize the interface with animated themes and light/dark modes.
Filling the Pods
Since the G3 Pro Koko uses Caliburn G3 pods, the filling process is exactly what you’ll remember if you’ve used any of the other devices in this series—just fill the pod from the top with your preferred e-liquid.
You’ll want to use a 50/50 PG to VG ratio for this device to avoid oversaturation and coil gunk. Each pod takes up to 2mL of e-liquid, but we recommend holding off on the last 25% or so to further reduce the risk of leakage.
Ease of Use
No complaints here—the G3 Pro Koko is pretty much plug-and-play. The pods snap in magnetically, and the device is draw-activated, so you won’t have to mess around with any buttons to fire it.
There’s actually just one button here, and it’s on the side. You can press it to access airflow and wattage controls, and it also locks and unlocks the customization menu. This simple and intuitive approach keeps the device feeling extremely user-friendly.
Key Points:
- A premium feel from the moment you open the box
- Easy, intuitive controls help you get set up fast
- 50/50 VG to PG e-liquid recommended
- Compatible with 2mL UWell G3 pods
Using the Caliburn G3 Pro Koko
Draw Quality & Modes
The G3 Pro Koko is designed to support both MTL and RDL vaping styles. Here’s what we suggest based on our experience:
- Use the included 0.4Ω pod at higher output for a warmer, more powerful draw (RDL)
- Choose the 0.9Ω pod and dial the power down for a smoother hit (MTL)
Adjusting the wattage is easy—just press the side button three times. You can dial it up to 35W for maximum power, but we found ourselves staying well below that threshold, even when using it for RDL vaping.
From there, you can dial in your preferences even further via the airflow controls. Press the side button twice to unlock them, then manually move the slider until you’re getting the draw you want. We found this process straightforward and no-nonsense on the G3 Pro Koko—you get a lot of room to play, but users who are newer to vaping certainly won’t get overwhelmed.
Battery Life
The 1250 mAh battery on the Koko is large enough to last multiple days per charge as long as you’re using it a light to moderate amount—and you can expect it to go even longer at lower wattages. We only spent a few days with this device, but found that the battery strength remained pretty consistent the whole time.
Fast charging via USB-C is also a nice touch—it means you’ll hit 80% battery in 20 minutes once you plug the thing in. For best results, remember to charge your device as soon as the battery gets low—leaving it dead for long periods will likely affect the battery’s longevity over time (although we didn’t have the device long enough to confirm this).
Key Points:
- Mesh coil options: 0.4Ω and 0.9Ω
- Excellent flavour clarity and lifespan
- 1250 mAh battery lasts for days per charge if properly maintained
Pro Tips for Caliburn G3 Pro Koko Users
- Use 0.9Ω pod at 12–18W for salt nic and longer pod life
- Start with 0.4Ω pod at 22–28W for bigger clouds
- Use "Night Mode" to save battery and reduce screen brightness
- Lock airflow before putting it in your pocket to prevent accidental changes
- Refill pods at the halfway mark to avoid dry hits
- Charge the device as soon as the battery gets low to prevent damage
