UWELL - Caliburn KOKO GK3 Pod Kit


Expanding on the forever-loved Caliburn KOKO series, the brand new Caliburn KOKO GK3 Pod Kit by UWELL is a user-friendly device fitted with premium features for vapers of all experience levels to enjoy!

Fitted with a generous 900mAh battery, topped up in a flash via USB-C fast charging, the GK3 provides more than enough power for a full day of vaping; boasting 20% more capacity compared to previous KOKO iterations.

The GK3's retro, segmented display screen requires less battery demand than OLED alternatives and allows your device to focus all its power on what it was made for; vaping! From the GK3's display, you can keep current with your device's battery level, current wattage, the resistance of your installed pod and puff counter! 

With one click of the GK3's side button, easily toggle the brightness of the display's backlight. Three clicks allows you to adjust the wattage output of your KOKO GK3, while four clicks will reset your puff counter back to zero. Featuring a NZ compliant shutoff timer, automatically deactivating your GK3 8 minutes after your last puff, the GK3 can be activated with 5 simple clicks of the side button.

Included with the Caliburn GK3 are two Caliburn G3 Replacement Pods; 0.6Ω or 0.9Ω which can be used for freebase or salt nicotine e-liquids respectively. The third generation of KOKO pods features all-new ultrasonic welding technology, ensuring a clean, mess-free refilling experience via the side-fill system. The upgraded Flavour 3.0 technology not only ensures consistent flavour but also helps to optimise nicotine delivery. Additionally, the G3 Pods have an upgraded capacity of 2.5mL and users can easily discern if their pod is in need of a top-up via the e-liquid window on the device.

Turning the clock back with its retro design and look, yet keeping it current with upgraded design features; the UWELL Caliburn KOKO GK3 is a seamless blend of form and function. Available in a matchbox-style build, and offering 4 dazzling colours to choose from; the GK3 is an easy-to-use companion for vapers of all experience levels!

UWELL - Caliburn KOKO GK3 Pod Kit

The user-friendly interface & the fact that the GK3 is square is a winner for me! With the dementia safety mechanism on new devices you won't have an issue with finding the firing button on the GK3. I'm constantly doing too many clicks on my pen device wiping out the puff count, changing the wattage. Not anymore, the GK3 sits nicely in the palm of your hand.
The G3 pods have excellent longevity (2k+ puff count).
Highly recommend giving the GK3 a go!

Wow - what a stellar review, Vaughan! Thanks for the amazing feedback. It's great to hear you're enjoying your new GK3 and getting a good number of puffs from the pods! The square-style device certainly suits some folks better than others so it's great you found it to be a perfect-fit! Thanks again for the amazing review (:
