Uwell Caliburn GK2 Pod Kit

Welcome to Select Vape Club, where we hand-pick only the finest vaping hardware for the discerning enthusiast. We are absolutely delighted to present the Uwell Caliburn GK2 Pod Kit – a device that represents the pinnacle of compact vaping engineering. If you have been searching for a discreet, take-anywhere companion that delivers exceptional flavour without compromise, your search ends here.

The Uwell Caliburn GK2 is the result of Uwell listening carefully to the vaping community. It takes everything vapers have loved about the legendary Caliburn series – renowned for its outstanding flavour reproduction and coil longevity – and combines it with the beloved pocket-friendly form factor of the bestselling Koko devices. The outcome is nothing short of remarkable: a super-compact device that slips unnoticed into your pocket or handbag, yet houses a surprisingly powerful 690mAh built-in battery. This long-lasting cell will comfortably see you through a full day of regular vaping, whether you are commuting, working, or enjoying an evening out. And when the battery eventually runs low, the included USB-C charging cable ensures you are back to full power in minimal time.

But the GK2 is not just about power; it is about personality. The device features a dazzling steampunk-inspired print that catches the light beautifully and resists everyday scratches and fingerprints. This is a device you will be proud to pull out of your pocket. The textured finish also provides a reassuringly grippy surface, meaning the GK2 feels secure in your hand.

Using the Caliburn GK2 could not be simpler. It is draw-activated, meaning there are no buttons to press – you simply inhale on the mouthpiece just as you would a traditional cigarette. The auto-draw sensor is instantaneous and responsive, delivering vapour the moment you take a puff. For those who enjoy a degree of customisation, Uwell has thoughtfully included an adjustable airflow wheel located at the base of the pod. By rotating this wheel, you can fine-tune your draw from a tight, resistance-heavy mouth-to-lung (MTL) experience that closely mimics the sensation of smoking, to a looser, airier restricted direct-lung (RDL) inhale that produces more vapour. This level of adjustability is rarely found on devices of this size.

The refillable G2 pod is a masterclass in practical design. With a capacity of 2ml – fully compliant with UK TPD regulations – it holds enough e-liquid for a satisfying session without constant top-ups. The snap-fit mouthpiece detaches effortlessly with a fingernail, revealing a leak-resistant fill port beneath. Refilling is clean, intuitive, and mess-free, accommodating both dripper nozzles and standard bottle tips. The pods incorporate Uwell's proprietary Pro-FOCS (Flavour Obsession Core System) flavour technology, which is engineered to lock in the authentic taste of your e-liquid and deliver incredibly crisp, clean, and layered flavour notes from the first puff to the last. Whether you are vaping a complex tobacco blend, a refreshing fruit medley, or a sweet dessert creation, the GK2 renders every nuance with precision.

The GK2 kit is also wonderfully versatile when it comes to coils. It is compatible with Uwell's full range of Caliburn G coils, offering a wide variety of resistances and vape sensations. The kit includes both a 0.8 Ohm and a 1.2 Ohm mesh coil, allowing you to experiment immediately. Changing coils is a breeze thanks to the push-to-fit design – simply pull out the old coil from the base of the pod and push a new one in. No tools, no mess, no hassle.

At Select Vape Club, we confidently recommend the Uwell Caliburn GK2 for use with high-PG e-liquids, 50/50 VG/PG blends, and nicotine salts. Its fixed 18W power output is perfectly calibrated to these juice types, ensuring optimal coil saturation and vapour production without any risk of burning. This is the ultimate take-anywhere discreet vape device that delivers exceptional flavour. Welcome to your new favourite vape.

Colours 

At Select Vape Club, we offer the Uwell Caliburn GK2 in an impressive array of stunning finishes. Each colour variant features the signature steampunk gear print, beautifully rendered against a unique base hue. Here is your guide to each one:

• Limpid Green: A translucent, crystal-clear green that resembles sea glass or a vintage apothecary bottle. This finish allows you to see the internal components of the device, giving it a fascinating, almost scientific aesthetic. The steampunk gear pattern is subtly etched into the transparent shell, creating depth and intrigue. Perfect for vapers who appreciate seeing the engineering within.

• Limpid Yellow: A bright, cheerful, translucent yellow that radiates warmth and energy. This finish is like captured sunshine. The transparent body allows the inner battery and circuitry to be visible, creating a unique layered effect. The steampunk print appears to float within the material. Ideal for those who want a device that stands out and sparks conversation.

• Limpid Pink: A soft, feminine, translucent pink that is both elegant and playful. This finish has a delicate, almost candy-like appearance while maintaining the sophisticated steampunk gear etching. The transparency adds a modern twist, allowing light to pass through and illuminate the internal structure. Perfect for vapers seeking a device that is both cute and classy.

• Ribbon Red: A deep, rich, opaque red with a subtle metallic sheen. This is not a bright, fire-engine red; it is a sophisticated, wine-inspired crimson that exudes confidence and passion. The steampunk gear print is rendered in contrasting dark bronze and gold tones, creating a regal, almost heraldic appearance. Ideal for those who want bold, unmistakable colour.

• Matte Black: The ultimate classic. A sleek, non-reflective black finish that is understated, professional, and endlessly versatile. The steampunk gear pattern is ghosted into the surface in a subtle gunmetal grey, making it visible without being flashy. This finish resists fingerprints beautifully and will appeal to vapers who value timeless, minimalist style.

• Aurora Green: A mesmerising, iridescent finish that shifts colour as it catches the light. Depending on the angle, Aurora Green can appear as deep forest green, vibrant emerald, or even hints of blue and purple. The steampunk gears are etched into this colour-shifting surface, creating a dynamic, almost supernatural appearance. Perfect for those who love nature-inspired beauty.

• Ocean Flame: A stunning gradient that transitions from deep ocean blue at the base to a warm, fiery orange-red at the top. This finish captures the essence of a sunset over the sea. The steampunk gear print overlays this gradient, adding a mechanical precision to the organic colour flow. Ideal for vapers who want a device that is truly unique and eye-catching.

• Limpid Cyan: A cool, refreshing, translucent cyan that evokes images of tropical lagoons and clear summer skies. This finish is crystal-clear with a blue-green tint that is both calming and invigorating. The internal components are visible, and the steampunk etching appears to float within the transparent shell. Perfect for vapers who favour cool, clean aesthetics.

• Limpid Black: A dramatic, smoky, translucent black that offers the best of both worlds: the mystery of black with the intrigue of transparency. This finish allows you to see the internal battery and circuitry through a dark, tinted lens, creating a stealthy, high-tech look. The steampunk gear pattern is subtly visible, adding texture. Ideal for the modern vaper who wants sophistication with an edge.

• Limpid Grey: A sophisticated, translucent grey that sits perfectly between clear and smoky. This finish is understated, modern, and incredibly versatile. The transparency reveals the inner workings of the device while the grey tint adds a layer of mystery. The steampunk etching is visible but not overpowering. Perfect for vapers who appreciate industrial-chic design and neutral tones.

How to Use

1. Initial Unboxing: Remove the device and all components from the packaging. Inspect the device and pod for any visible damage that may have occurred during transit.

2. Prime Your Coil (Essential Step): Take the 0.8 Ohm coil (or the 1.2 Ohm spare). Apply 2-3 drops of your chosen e-liquid directly into the central chimney of the coil and onto the exposed cotton wicking ports. This saturates the cotton and prevents dry burning on your first puff.

3. Fill the Pod: Detach the snap-fit mouthpiece by pulling it firmly upwards. Locate the silicone rubber plug covering the fill port. Lift the plug using your fingernail. Insert your e-liquid bottle nozzle and fill the pod with your chosen 50/50 or nicotine salt e-liquid. Fill only until the liquid reaches the 2ml capacity mark. Do not overfill. Reseal the plug firmly and reattach the mouthpiece until you hear a click.

4. Allow Saturation Time: After filling, place the pod upright on a tissue for 5-7 minutes. This crucial waiting period allows the cotton wick to become fully saturated with e-liquid, ensuring optimal flavour and coil longevity.

5. Insert the Pod: Slide the filled pod into the device body until it clicks securely into place. The magnetised connection will guide it automatically into the correct position.

6. Activate the Device: The Caliburn GK2 is draw-activated. There is no power button. Simply inhale from the mouthpiece. The LED indicator light will illuminate to confirm activation and vapour production.

7. Adjust the Airflow: Locate the small knurled wheel on the underside of the pod. Rotate this wheel while taking test puffs:

   • Rotate fully clockwise for maximum resistance (tight, cigarette-like MTL draw).

   • Rotate fully anti-clockwise for minimal resistance (smoother, airier RDL draw).

   • Find your sweet spot somewhere in the middle for a balanced experience.

8. Monitor Battery Life: The LED light communicates remaining battery charge:

   • Green Light: 60% to 100% remaining.

   • Blue Light: 30% to 60% remaining.

   • Red Light: Less than 30% remaining – recharge soon.

9. Charge the Device: When the battery is low, connect the USB-C cable to the device and a suitable 1A-2A USB power source. The LED will glow red during charging and will turn off completely when the 690mAh battery is fully charged (approximately 45-60 minutes).

FAQ’s

1. Q: Is the Uwell Caliburn GK2 suitable for a complete beginner who has never vaped before?
   A: Absolutely. The GK2 is one of the most beginner-friendly devices on the market. Its draw-activated firing mechanism means there are no confusing buttons or settings to navigate. The snap-fill pod system is intuitive, and the adjustable airflow allows new users to find their preferred draw. It is an excellent choice for adult smokers transitioning to vaping.

2. Q: Which e-liquids work best with the Caliburn GK2?
   A: The GK2 is optimised for 50/50 VG/PG blends, high-PG e-liquids, and all nicotine salt formulations. These thinner e-liquids wick efficiently through the Caliburn G coils, delivering exceptional flavour and preventing dry hits. Avoid high-VG (70% VG or higher) e-liquids as they are too thick for this device.

3. Q: How long does the 690mAh battery last on a full charge?
   A: Battery life depends on your usage frequency and draw length. For an average vaper using the 0.8 Ohm coil, you can expect approximately 6 to 8 hours of intermittent use, which typically translates to 1.5 to 2 fully filled pods. Heavy vapers may need to recharge once during the day.

4. Q: How do I know when it is time to replace the coil?
   A: You will notice one or more of the following signs: a distinct drop in flavour intensity, a muted or burnt taste, a significant decrease in vapour production, or gurgling sounds during inhalation. Typically, a Caliburn G coil lasts between 1 to 2 weeks depending on the sweetness of your e-liquid.

5. Q: Can I use Caliburn G original pods with the GK2 device?
   A: No. The GK2 is designed specifically for the G2 Pod. However, the G2 pod is backward compatible with all Caliburn G Coils. You must use the pod that came with your GK2 or a replacement G2 pod for proper fit, airflow control, and leak resistance.

6. Q: Does the adjustable airflow wheel actually make a noticeable difference?
   A: Yes, significantly. The wheel ranges from fully closed (providing a very tight, resistance-heavy draw similar to a traditional cigarette) to fully open (providing a smooth, airy restricted direct-lung inhale). The range of adjustment is impressive for a pod system of this size and offers genuine customisation.

7. Q: Is the device covered by any warranty?
   A: Select Vape Club provides a limited manufacturer's warranty against defects in materials and workmanship. Please retain your proof of purchase and contact our customer service team for assistance. Normal wear and tear, coil degradation, and damage caused by improper use or e-liquid leakage are not covered.
