Caliburn GK2 Pod

Product Review: Caliburn GK2 Pod by UWELL Pod System

The Uwell Caliburn GK2 Pod Kit is the newest addition to the Caliburn line, which has always been very good. Uwell's Caliburn line has had many hits, many of which have been on our Best Vapes lists. Caliburn, Caliburn A2, Caliburn AK2, and Caliburn G2 are examples.

So, what does the GK2 pod add to the market?

The GK2 is a mix of the two great Caliburn styles, as you might guess from the name. It has a square shape like the Koko Pod and AK2 (K), but it is in the Caliburn G range and uses coils that can be changed (G2).

What can we expect with the Uwell Caliburn GK2?

Appearance & Design

The Uwell Caliburn GK2 is made of a sturdy zinc alloy material and is meant to be portable while producing exquisite taste and vapour. It's the perfect solution if you're searching for a kit to carry with you on the road, weighing just 45.2g overall and with a lanyard.
The way the front panel lights up is one of the GK2's most notable and eye-catching characteristics. The light changes colour and is more eye-catching than a basic LED light. It serves as a battery capacity guide and is more eye-catching than a simple LED light.

has KOKO-shaped light bars that flash different colours at varying power levels, and it can vibrate in different states. Vapers will have a greater interactive experience with these two designs.
The pod is translucent with a hint of frosting, making it easy to see the remaining charge levels whether within or outside the battery portion. The GK2 uwell pod system is identical to that of the Caliburn G2. It includes a 2ml juice capacity and a top-fill mechanism accessible by snapping off the mouthpiece. It also contains the same adjustable airflow control wheel on the pods base, allowing you to fine-tune your vaping experience even further.

The GK2 utilises the Caliburn G2 cartridge, which incorporates a bottom-mounted adjustable gear wheel. The cartridge is transparent, and it pairs well with the mod's huge window for monitoring e-liquid levels. Its top-filling design is easy and clean, allowing you to replenish e-liquid without having to remove the cartridge. There's no need to be concerned about getting your hands filthy.


The GK2 works with the Caliburn G2 1.2 meshed coil, the Caliburn G 0.8 meshed coil, and the Caliburn G 1.0 coil. The kit comes with two mesh coils of 1.2 and 0.8. More flavour options are provided for vapers.



it's shaped like a box. it's very easy to hold because it's so thin. It's also easy to hide when you need to be as quiet as possible.
The main panels are covered with silicate glass, making them feel very smooth. Only time will tell if it can take being hit and scratched. The colour change around the kit's edges works well. The top corner of the lanyard clip is shaped so that it doesn't get in the way when vaping. The Type C USB charging port is on the bottom of the battery section, which is a good place. A green light that blinks during the vapes means that the battery strength is more than 60%. When it turns blue, the battery has between 30% and 60% of its charge left. A red glimmer shows less than that. There's an 8-second cutoff for vaping, so if the lights flash green five times and you feel two waves of vibration, you're vaping too much.
When the red-light flashes constantly and the battery vibrates three times, it's time to charge the kit.

The lights also warn of any possible safety problems:

Safety against short circuits. Yellow blinks four times and shakes four times.
Safety from low voltage. Red blinks 10 times and shakes 3 times.
Protection for overtime. Green glow times five, vibration times two open circuit indications. Open circuit indication: Blue blinks three times and shakes twice.
The lights will also flicker when the pods are put on or taken off the battery section. The colour changes based on how charged it is.
