Uwell Caliburn GK2: What Changed and What to Buy Now
The Uwell Caliburn GK2 was a KOKO shaped pod we first wrote about in 2023, built on the Caliburn G2 pod. The kit itself is sold out now. What changed since then is mostly the pod: newer Caliburn KOKO models moved to a different cartridge. This page explains what the GK2 was, which parts still fit it, and which in stock Caliburn to buy if you want a new one.
What the GK2 was
A small, rounded device with a 690mAh battery and up to 18W. It used a 2ml top fill pod with an airflow wheel at the bottom, and press fit Caliburn coils inside. The KOKO light changed colour with the power level, and the device vibrated to warn you about low battery, long puffs, a coil fault or a newly inserted pod. It measured 72.2 x 46.6 x 16.3mm and weighed 45.2g.
It was listed at Rs 7,500 with us. It is out of stock right now. Ask us on WhatsApp if you want to know when it is back.
Parts that still fit the GK2
This is the useful part for anyone who owns one. The GK2 runs on the G2 pod, and both the pod and coils are in stock (checked 9 Nov 2026):
- Caliburn G2 / GK2 empty pod, Rs 799 for one pod, coil sold separately. Change it when the plastic gets stained or the seal starts to leak.
- Caliburn G2 replacement coils, Rs 850 each, in 1.2 ohm (MTL) or 0.8 ohm (looser draw).
- Caliburn G / G2 / Koko Prime coils, Rs 799 each, 0.8 or 1.2 ohm. G and G2 coils swap between pods.
Before you fit a new coil, drip a few drops onto the cotton, fill the pod and wait 5 minutes. A dry first puff burns new cotton and that coil cannot be saved. Our coil price and fit guide lists other models too.
What to buy now
There are two routes. Stay on G2 pods so your spares keep working, or move to the newer GPP cartridge that later Caliburn KOKO kits use. Prices checked 9 Nov 2026.

Keep your G2 spares: GK2 Vision
The GK2 Vision is the nearest thing to the old kit. It is the same size within a fraction of a millimetre, the same 18W, the same 2ml top fill pod, and it takes the Caliburn G and G2 coils listed above. It costs a third of what the GK2 was listed at. If you have a drawer of G2 coils, this is the one.
Start fresh: GK3 Tenet or G5 KOKO
The GK3 Tenet gives you 1000mAh and up to 25W, with two G3 cartridges in the box (0.6 ohm side refill and 0.9 ohm top refill). Turning the pod switches between two airflow settings. The G5 KOKO is a step up again: 1600mAh, power up to 35W in 1W steps, a side refill 3ml pod and a leather covered body. Note that old G2 and GK2 pods do not fit the GPP kits, so budget for new cartridges. The G5 Lite comparison covers that family in detail.
GK2 questions
Is the GK2 Vision the same as the GK2?
Not identical, but close. It shares the 18W output, the 2ml G2 pod and the coil fit. The body is aluminium alloy.
Will GK2 pods fit a Caliburn G5 KOKO?
No. The G5 family uses GPP cartridges. G2 pods only fit G2 based kits such as the G2, GK2, GK2 Vision, GZ2 and Tenet.
Which coil for nicotine salt?
The 1.2 ohm. It gives a tight mouth to lung draw that works well with salts at 20 to 50mg.
