Why Choose the Uwell Caliburn GK2?
Compact 690mAh Battery
The Caliburn GK2 uses a 690mAh built-in battery, providing practical capacity for a compact pod device. The built-in design means there are no external batteries to buy, install or carry.
Battery life depends on your coil resistance, puff duration and vaping frequency. The LED indicators and vibration feedback help you recognise when the battery is low and the device needs charging.
18W Maximum Output
The GK2 provides up to 18W of output for a controlled mouth-to-lung vape. Its power level is suited to the compatible Caliburn G and G2 coils included with the kit.
The 1.2Ω Caliburn G2 mesh coil offers a tighter and cooler MTL draw, while the 0.8Ω Caliburn G mesh coil can provide a warmer inhale with increased vapour production. Use the correct coil and avoid exceeding its recommended operating range.
Refillable 2ml Top-Fill Pod
The Caliburn GK2 includes a 2ml refillable pod with a top-fill design. The top-fill system allows you to add e-liquid without removing the pod from the device, making everyday refilling quicker and more convenient.
The transparent pod window makes it easy to check the e-liquid level. Refill the pod before it becomes nearly empty to help keep the coil saturated and reduce the risk of a dry hit.
Adjustable Airflow Wheel
The airflow adjustment wheel gives you control over the tightness of the draw. Open the airflow for a looser MTL inhale with more air, or close it slightly for a tighter draw and more concentrated flavour.
Small airflow adjustments can change the warmth, vapour level and overall feel of the vape. Set the airflow to suit the resistance of the installed coil and your preferred e-liquid.
Caliburn G and G2 Coil Compatibility
The Caliburn GK2 is compatible with three Uwell coil options: the Caliburn G2 1.2Ω mesh coil, the Caliburn G 0.8Ω mesh coil and the Caliburn G 1.0Ω coil.
The 1.2Ω mesh coil and 0.8Ω mesh coil are included with the kit. The 1.0Ω Caliburn G coil is available separately and provides another option for a balanced MTL experience.
Automatic Draw Activation
The GK2 activates when you inhale, so there is no need to press a fire button for every puff. This makes the device simple to use and suitable for vapers who prefer a draw-activated pod system.
Use a steady mouth-to-lung inhale through the mouthpiece. If the device does not activate, check the pod connection, battery level and airflow path.
LED Light and Vibration Feedback
The Caliburn GK2 combines LED light bars with vibration feedback to create a more interactive vaping experience. The light display changes according to the device's operating or battery status, while vibration alerts can indicate conditions such as low voltage, an open circuit or pod installation.
The visual and haptic feedback helps you monitor the device without needing a large screen or a complex menu system.
Pro-FOCS Flavour Technology
Uwell's Pro-FOCS flavour technology is designed to support a clear and consistent flavour experience. The compatible mesh coils heat e-liquid evenly and are suited to the controlled vapour production expected from a compact MTL pod kit.
Lightweight Carrying Design
The Caliburn GK2 weighs approximately 45.2g and has a compact shape designed for everyday carrying. The included lanyard allows you to keep the device close at hand without placing it in a pocket or bag.
Its glass panel and LED light bars give the GK2 a distinctive appearance, while the aluminium alloy and polymer construction keeps the device lightweight.

How to Set Up the Uwell Caliburn GK2
How Do You Fill the GK2 Pod?
To fill the Caliburn GK2 pod, open the top-fill section while the pod remains fitted or remove it if you prefer. Add suitable e-liquid through the filling port and close the cap securely before vaping.
- Open the pod's top-fill section.
- Add suitable e-liquid without exceeding the 2ml capacity.
- Close the top-fill section firmly.
- Allow a new coil to soak for at least five minutes.
- Check that the pod is fitted correctly.
- Take a slow, gentle inhale through the mouthpiece.
How Long Should You Wait Before Vaping?
Wait at least five minutes after filling a new coil so the e-liquid can saturate the mesh. Taking puffs too soon can cause a dry or burnt taste.
How Do You Adjust the Airflow?
Turn the airflow wheel to adjust the draw. A more open setting provides a looser inhale and more air, while a more closed setting provides a tighter and warmer MTL draw.
How Do You Change the Coil?
To change the coil, remove the pod from the device, pull out the old coil and press a new compatible Caliburn G or G2 coil into the pod base. Fill the pod and wait at least five minutes before vaping.
Make sure the coil is fitted straight and securely. Replace the coil when the flavour becomes burnt, harsh or noticeably weaker.
Which E-Liquid Should You Use with the Caliburn GK2?
The Caliburn GK2 is designed for mouth-to-lung vaping and is generally suited to 50/50 e-liquids. Nicotine salts can provide a smooth option for adult vapers who prefer higher nicotine strengths, while standard 50/50 e-liquid can also be used at an appropriate strength.
The 1.2Ω coil is suited to a tighter and cooler MTL draw. The 0.8Ω coil can produce a warmer vape with more vapour, so choose a nicotine strength that matches your vaping style.
Avoid very thick high-VG e-liquid in this compact pod system because it may not wick efficiently through the coil. If the e-liquid is too thick, the pod may produce a dry taste or struggle to keep up with repeated puffs.
Nicotine-containing e-liquid is intended for adults aged 18 and over. Nicotine is addictive. Follow the product label and use nicotine strengths responsibly.
How to Get Better Performance from the Caliburn GK2
- Prime every new coil before taking your first puff.
- Wait at least five minutes after filling a new coil.
- Use a suitable 50/50 e-liquid.
- Keep the pod filled above the minimum e-liquid level.
- Take slow, steady mouth-to-lung puffs.
- Adjust the airflow gradually instead of opening or closing it fully at once.
- Clean condensation from the pod connection regularly.
- Keep the airflow path clear.
- Recharge the device before the battery becomes completely empty.
- Replace the coil when the flavour becomes burnt or muted.
- Keep the device away from excessive heat and moisture.
- Do not use a damaged pod, coil, cable or charging port.
When Should You Replace a GK2 Coil?
Replace the coil when you notice a persistent burnt taste, reduced flavour, reduced vapour production or a harsh inhale. Coil lifespan depends on e-liquid sweetness, vaping frequency, puff length and the resistance of the installed coil.
The GK2 uses replaceable Caliburn G and G2 coils, so you do not need to replace the entire pod when the coil wears out. Keep the pod if it remains in good condition and fit a new compatible coil.
