Uwell Caliburn GK2 Key Features

Compact, wide body

At 72.2 x 46.6 x 16.3mm, the GK2 is short and wide rather than a long stick, and a lanyard comes in the box.

Two coils in the box

The 1.2Ω coil gives a tight mouth-to-lung (MTL) draw; the 0.8Ω spare gives a little more vapour.

Transparent window

A clear window shows the e-liquid level, and SourceMore lists Uwell’s Pro-FOCS adjustment technology.

Adjustable airflow and top fill

Tune the draw with the airflow control and refill from the top.

Pods and Coils for the Caliburn GK2

These kits use a refillable 2ml Caliburn G-style pod with a removable coil, so you replace the coil, not the whole pod. SourceMore lists the Caliburn G coils (UN2 Meshed-H 0.8Ω and 1.0Ω, 4 per pack) as compatible with the Caliburn G, G2, GK2, KOKO Prime and Tenet kits, and the G2 1.2Ω Meshed-H coil also fits the G2 and GK2. We stock Uwell Caliburn G coils, Caliburn G empty pods and Caliburn G/G2 pods with coils. The 1.0–1.2Ω coils give a tight mouth-to-lung (MTL) draw; the 0.8Ω coil gives a little more vapour.

How to Use the Uwell Caliburn GK2

Charge the device fully before first use.
Fit a coil in the pod and fill the pod from the top, leaving a little space.
Refit the pod and wait about five minutes for the coil to soak.
Set the airflow and inhale gently to start.
Replace only the coil when the flavour fades.

Best E-Liquid for the Caliburn GK2

With 0.8–1.2Ω coils at up to 18W, these kits are made for nicotine salt e-liquid and a mouth-to-lung draw. Thin 50/50 freebase also works. Browse our UAE e-liquids.

Troubleshooting

Burnt taste: the cartridge was not soaked long enough, or it ran dry. A burnt coil cannot be recovered, so fit a new cartridge and wait about five minutes after filling.
No vapour when drawing: check the battery, make sure the cartridge is seated firmly, and wipe the contacts dry.
Gurgling or e-liquid in the mouthpiece: the cartridge may be overfilled or the device was left in the heat. Remove the cartridge, blow gently through the mouthpiece, and store the device upright.
Leaking: check the fill port is closed firmly and that the cartridge has no cracks.

Care Tips for the UAE Climate

Heat is hard on pod kits. Do not leave the device in a parked car or in direct sun: high temperatures thin e-liquid, which can make cartridges leak, and they are bad for lithium batteries. Wipe the cartridge contacts now and then with a dry tissue, and charge with a standard 5V charger.
