Uwell Caliburn GK2 Pod Kit

Uwell Caliburn GK2 Pod Kit

Two mesh coils, adjustable airflow, and a proper mouth-to-lung draw make the Uwell Caliburn GK2 one of the easiest refillable pod kits to recommend.

It runs a 690mAh battery at a steady 18W, fills from the top into a 2ml refillable pod, and takes the well-loved Caliburn G-series coils in 0.8Ω and 1.2Ω. Draw-activated firing means there is no button to press: just inhale.

Add colour-shifting RGB lights and a lightweight PC+ABS and glass body at 45.2g, and you have a compact MTL kit built for former smokers and everyday vapers alike. It sits among our Refillable Pod Kits and MTL vape kits.

Why vapers choose this:

• Two Caliburn G mesh coils in the box mean you can run a tighter 1.2Ω or a warmer 0.8Ω from day one, so you can dial in the draw and flavour without buying anything extra.

• Top-fill 2ml pod for quick, mess-free refills.

• Adjustable airflow to fine-tune from tight MTL to a looser pull.

• Draw-activated firing, so there is no button to remember.

• USB-C charging and a remarkably lightweight 45.2g pocket-friendly body.

Uwell Caliburn GK2 Features

Two Mesh Coil Options

The GK2 ships with a 1.2Ω Caliburn G2 coil pre-installed and a spare 0.8Ω Caliburn G coil. The 1.2Ω gives a tighter, cooler cigarette-style draw, while the 0.8Ω runs a touch warmer with a bit more vapour. Both are mesh, so flavour comes through clean and even. When they wear out, our Uwell Coils range has replacements.

Easy Top-Fill Pod

Refilling is a quick top-fill job. Simply snap the black mouthpiece off the pod to reveal the red fill port, add your e-liquid, and snap it back on. The pod holds 2ml, and a transparent window lets you eyeball the level so you refill before it runs dry.

Adjustable Airflow

A dial on the base lets you tune the draw from a tight MTL pull to something airier. Small adjustments make a real difference to how warm and how full each puff feels, so you can set it to taste rather than settle for a fixed draw.

Ideal for Nic Salts

As an MTL kit at 18W, the GK2 pairs naturally with nic salt e-liquid, giving a smooth, quick hit that suits ex-smokers and former disposable users. Fill it from any 10ml bottle in our Nic Salts Range, and you are set.

Lightweight and Easy to Carry

The PC+ABS and glass body weighs just 45.2g, and a lanyard point plus included lanyard make it easy to keep on you. Colour-shifting RGB lights and subtle haptic feedback add a bit of character, while the magnetic pod clicks in cleanly. It is a proper reusable device that charges over USB-C and slots into our rechargeable vapes lineup.

How to Set Up the Uwell Caliburn GK2

Quick to get going.

1. Charge it fully over USB-C before first use, watching the LED indicator.

2. Fit your coil by pushing it firmly into the base of the pod until it seats perfectly flush.

3. Snap the black mouthpiece off the pod to open the top fill port and add your e-liquid, up to 2ml.

4. Snap the mouthpiece back on securely and wipe away any excess with a dry tissue.

5. Stand the pod upright for five to ten minutes so the cotton completely saturates. Firing a dry coil will instantly ruin it.

6. Click the pod in, set the airflow dial on the base of the pod, and inhale on the mouthpiece to fire.
