Uwell Caliburn GK2 Pod Kit

Welcome to Vaping Supplier – your premier B2B distribution hub for authentic, high-demand, and high-margin vaping hardware from the world's leading manufacturers. We are proud to present a comprehensive wholesale analysis, technical specification, and product briefing for the Uwell Caliburn GK2 Pod Kit. This SKU represents a top-tier, high-turnover product that has demonstrated exceptional sell-through rates across the UK and European markets. For retailers looking to stock a device that seamlessly bridges the gap between beginner-friendly accessibility and advanced flavour performance, the Caliburn GK2 is a strategic and profitable inventory addition.

The Uwell brand has long been synonymous with reliability, innovation, and consumer trust within the vaping industry. The Caliburn series, in particular, enjoys an almost cult-like following among vapers of all experience levels. The GK2 model consolidates the best elements of the Caliburn line (outstanding flavour reproduction, exceptional coil longevity, intuitive ease of use) with the beloved Koko form factor (compact, rounded, pocket-friendly, discreet). The result is a product with near-universal consumer appeal. It satisfies the mature ex-smoker seeking a simple, reliable MTL device. It delights the dedicated flavour chaser who primarily uses nicotine salts. And it serves the experienced vaper who wants a rugged, pocketable backup device for travel or work. By stocking the GK2, you are catering to multiple consumer segments with a single, unified SKU. This reduces inventory complexity while maximising sales potential and inventory turnover rates.

From a technical wholesale perspective, the Caliburn GK2 is built around a 690mAh integrated lithium-ion battery paired with a fixed 18W output. This engineering decision is significant for retailers because it completely eliminates user error related to wattage adjustment. Your customers cannot accidentally set the power too high and burn their coils, nor can they set it too low and receive a weak, unsatisfying vape. This reliability directly translates to fewer returns, fewer support tickets, lower customer frustration, and ultimately, higher customer satisfaction and retention rates. The fixed output also ensures consistent coil performance across the entire battery discharge curve, meaning the flavour and vapour production remain stable from the first puff to the last. This directly translates to fewer warranty claims related to perceived device malfunction or burnt coils.

The device features a dazzling steampunk-themed chassis – a design language that has proven exceptionally popular in retail environments due to its unique, scratch-resistant, and visually distinctive finish. Unlike plain, generic pod systems that blend together on crowded retail shelves, the GK2 stands out. The textured steampunk print also provides a non-slip grip, reducing the likelihood of customers dropping and damaging their device (and subsequently requesting returns). The GK2 is offered in eleven distinct colour variants (detailed below), allowing brick-and-mortar and online retailers to create attractive display bundles, themed collections, seasonal promotions, and cross-selling opportunities. Multiple colour options also encourage repeat purchases from the same customer – many vapers collect multiple colours for different moods or outfits.

The pod system is the Caliburn G2 2ml Refillable Pod, which is fully TPD compliant for the UK market. This is non-negotiable for legal sale, and you can be confident that Vaping Supplier only stocks fully compliant hardware. This pod features Pro-FOCS flavour technology (Flavour Obsession Core System), a proprietary and trademarked Uwell innovation that retailers should prominently highlight in their product listings, in-store signage, and staff training materials. Pro-FOCS is a genuine differentiator – it delivers noticeably cleaner, crisper, and more authentic flavour compared to non-optimised pod systems. This feature alone can justify a higher retail price point and increase your per-unit margin.

The snap-fit mouthpiece allows for top-filling, a premium convenience feature that customers have come to expect. Tool-free, mess-free, and intuitive – this reduces the learning curve for new vapers and reduces support queries about how to fill the device. Underneath the mouthpiece, a leak-resistant silicone fill port further reduces the likelihood of e-liquid seepage, which is a common source of customer complaints and device returns. Happier customers mean fewer refunds and more repeat business.

Most importantly for your recurring revenue stream, the G2 pod is fully compatible with the entire Uwell Caliburn G Coil range (0.8 Ohm, 1.0 Ohm, and 1.2 Ohm resistances). This is a critical cross-selling and recurring revenue opportunity. Every GK2 device sold is a gateway to ongoing, repeat purchases of replacement coils (typically every 1-2 weeks per customer) and replacement pods (every 4-6 weeks). These consumables generate predictable, high-margin monthly revenue streams that quickly exceed the initial device sale. Stocking the GK2 is not just selling a device – it is acquiring a long-term customer relationship. We strongly advise wholesale partners to bundle the GK2 with multi-packs of Caliburn G coils and replacement G2 pods to maximise average order value and customer lifetime value.

The GK2 is draw-activated, meaning there are no buttons to press. This simplicity is particularly appealing to adult smokers transitioning to vaping, who often find complex devices intimidating. The auto-draw mechanism is sensitive and reliable, activating instantly upon inhalation. The device also features an adjustable airflow wheel on the base of the pod – a mechanical, stepless control that allows users to fine-tune their draw from a tight, resistance-heavy mouth-to-lung (MTL) experience to a looser, airier restricted direct-lung (RDL) inhale. This feature meaningfully differentiates the GK2 from lower-priced competitor devices and provides retail staff with a compelling sales point.

From a logistics and warehousing standpoint, the GK2 is exceptionally retailer-friendly. Each unit is lightweight (approximately 50g including packaging) and compact (box dimensions approximately 100mm x 60mm x 25mm). This optimises shipping density, reduces per-unit freight costs, and maximises the number of units you can store in your warehouse or display on your retail shelves. The device is available for wholesale ordering in master cartons. Contact your Vaping Supplier account manager for specific case pack quantities and tiered pricing based on volume.

Regarding e-liquid compatibility, the GK2 is optimised for 50/50 VG/PG blends, high-PG e-liquids (such as 70% PG / 30% VG), and all nicotine salt formulations (UK compliant up to 20mg). These thinner e-liquids wick efficiently through the Caliburn G coils, delivering exceptional flavour and preventing dry hits. We advise wholesale partners to stock the GK2 alongside a curated selection of these e-liquid types. High-VG e-liquids (70% VG or higher) are not recommended for the GK2, as they are too viscous to wick properly and will lead to dry hits, burnt coils, and customer dissatisfaction. Your retail staff should be trained to upsell appropriate e-liquids with every GK2 device sale.

In the box, each GK2 kit includes: one device, one G2 pod, a pre-installed 0.8 Ohm coil, a spare 1.2 Ohm coil (in sealed foil), a USB-C charging cable, and a multilingual user manual including British English. This means the customer can start vaping immediately upon purchase, which increases the likelihood of an immediate sale rather than a "I'll come back when I've bought coils" delay.

Finally, Uwell has a well-established reputation for quality control, customer support, and consistent manufacturing standards. By stocking Uwell products, you are aligning your business with a brand that vapers trust and actively seek out. The Caliburn GK2 is not just another vape kit – it is a reliable, high-margin, high-turnover product that builds customer loyalty, drives repeat business, and generates predictable consumable revenue.

How to Use (For Retail Staff Training & Customer Handouts)

Provide this information to your retail staff so they can confidently assist customers, or include it as a printed handout with each sale.

1. Unpack & Inspect: Remove all components from the retail box. Verify the box includes both 0.8 Ohm and 1.2 Ohm coils. Check the device and pod for any visible transit damage.

2. Prime the Coil (Crucial Step – Emphasise This to Customers): Before inserting the coil into the pod, add 2-3 drops of e-liquid directly into the top centre of the coil and onto the exposed cotton wicking windows on the sides. This saturates the cotton and prevents a burnt taste on first use. Failure to prime is the #1 cause of customer complaints.

3. Fill the Pod: Detach the black snap-fit mouthpiece by pulling it firmly upward (do not twist). Locate the silicone rubber plug covering the fill port. Lift the plug using a fingernail. Insert the e-liquid bottle nozzle and fill the pod with the customer's 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 (ensure no gaps). Reattach the mouthpiece until it clicks.

4. Allow Saturation Time (Do Not Skip): Place the filled pod upright on a tissue for 5-7 minutes. This waiting period is essential for the cotton to fully saturate with e-liquid. If the customer vapes immediately, they will burn the cotton and ruin the coil.

5. Insert the Pod: Slide the filled pod into the GK2 battery device. Magnets will guide it into the correct position. The customer will hear and feel a click.

6. Activate the Device (No Button): The Caliburn GK2 has no power button. It is always on and ready. The customer simply inhales from the mouthpiece. The LED indicator light will illuminate to confirm activation and vapour production.

7. Adjust the Airflow (Demonstrate This): 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 mouth-to-lung draw).

   • Rotate fully anti-clockwise for minimum resistance (smoother, airier restricted direct-lung draw).

   • Adjust to any position in between for a personalised experience.

8. Monitor Battery Life (Train Staff on LED Meanings): The single LED light communicates remaining battery charge:

   • Green Light: 60% to 100% remaining. Good to go.

   • Blue Light: 30% to 60% remaining. Several hours of use left.

   • 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 plug into a suitable 5V/1A USB power source (standard phone charger or USB port). The LED will glow red during charging. The light will turn off completely when the 690mAh battery is fully charged. Full charge time: approximately 45-60 minutes.

FAQ’s 

Q: Are there any known quality control issues with the Caliburn GK2 that I should be aware of before stocking?

A: Uwell has an excellent reputation for quality control, and the GK2 has proven highly reliable. The most common customer issues (which are typically user error rather than manufacturing defects) are: (a) failure to prime coils leading to burnt taste, (b) overfilling pods leading to leakage, and (c) not allowing saturation time. We recommend training your staff to emphasise these three points. Actual defective device rates are below 1%, which is industry-leading.

Q: What is the profit margin potential for the Caliburn GK2 and its consumables?

A: Excellent. The GK2 device itself offers healthy margins at typical retail pricing (typically 40-60% margin depending on your pricing strategy). However, the real profit is in the consumables. Caliburn G coils (0.8Ω, 1.0Ω, 1.2Ω) are high-margin items that customers purchase every 1-2 weeks. Replacement G2 pods are purchased every 4-6 weeks. Over a 12-month period, consumable sales from a single GK2 customer typically exceed the initial device sale by 3-5 times. Stocking the GK2 is acquiring a long-term, recurring revenue customer.

Q: Is the Uwell Caliburn GK2 fully TPD compliant for sale in the UK?

A: Yes, absolutely. The GK2 kit sold by Vaping Supplier features a 2ml tank capacity, which is fully compliant with the UK Tobacco and Related Products Regulations (TPD). The packaging, user manual, and labelling are also UK-specific and fully compliant. You can sell this product with complete confidence in your regulatory standing.

Q: What is the typical return rate for the Caliburn GK2, and how does Vaping Supplier handle wholesale returns?

A: Return rates are very low (typically less than 1% for manufacturing defects). Most "defective" returns are actually user errors (unprimed coils, overfilling, etc.). Vaping Supplier has a clear B2B returns policy for verified manufacturing defects. Please refer to your wholesale agreement or contact our support team for the full returns procedure. We do not accept returns for user error, used coils, or devices damaged by e-liquid leakage caused by improper use.

Q: Can the Caliburn GK2 be used with high-VG e-liquids (70% VG or higher)?

A: No, and we strongly advise training your retail staff to communicate this clearly to customers. The GK2's coil wicking ports and 18W fixed output are optimised for thinner e-liquids (50/50, high-PG, and nicotine salts). High-VG liquids are too viscous to wick through the Caliburn G coils. Customers who use high-VG liquids will experience dry hits, burnt coils within hours, and significant dissatisfaction. This is not a device defect – it is a compatibility issue. Train staff to upsell appropriate 50/50 or nicotine salt e-liquids with every GK2 sale. For customers who insist on high-VG liquids, recommend a different device (sub-ohm tank or high-wattage pod system).
