Overview
This UWELL Caliburn GK3 25W Pod Kit review looks at a compact refillable pod device with a 900 mAh built-in battery, a maximum output of 25W and a 2.5 ml cartridge. It is a specification-based review: every figure comes from the product listing on our store, we have not run bench tests, and where the listing is silent we say so rather than guess.
The kit pairs a dual airflow system with Pro-FOCS Flavor Tech, 2A Type-C fast charging and a lanyard loop, and it comes in Black, Blue, Red and Silver. Below you will find the design, output, airflow and charging details, a comparison with other Uwell kits we stock, the UAE rules that apply to refillable devices, pros and cons, and a short FAQ. The kit is for adults aged 21 and over only, and UAE law may set a higher age limit, so check the rules before you buy.

UWELL Caliburn GK3 25W Pod Kit review: quick verdict and best fit
The Caliburn GK3 is a refillable pod kit for people who want a tidy, modern device without moving up to a box mod. You fill the cartridge with e-liquid, fit it to the body and draw. There are no separate coils to build and no tank to strip down, because the coil is integrated into the cartridge. The listing names two cartridge options, a 0.6 Ω and a 0.9 Ω FeCrAl meshed Caliburn G3 integrated coil cartridge, so the choice of draw comes down to which one you pick and how you set the airflow.
On paper the kit suits someone who wants a pocketable device with adjustable character. A maximum output of 25W is modest next to larger pod mods, which is the point: it keeps the body small, and the 900 mAh battery matches that size. The dual airflow system lets you tighten or open the draw, and Pro-FOCS Flavor Tech is the brand name Uwell gives to its flavour-focused coil design.
It is less suited to anyone chasing very high wattage or large clouds. The listing publishes no puff count, no screen and no runtime figure, so we cannot comment on any of those, and we have not invented numbers to fill the gap.
Who should buy it
Buy it if you want a compact refillable kit with two cartridge resistances, dual airflow, Type-C fast charging and a lanyard loop for carrying, and you are comfortable buying cartridges and e-liquid separately.
Who should skip it
Skip it if you want a screen, a larger battery or higher wattage. The Uwell Caliburn G4 Mini review covers a 35W kit with a 1100 mAh battery, and the pod system category lists more options.
Design, size and colours
The listing gives dimensions of 74.8 mm × 49.2 mm × 17.1 mm and names the materials as PCTG and PC+ABS. Those figures describe a short, wide body rather than a long stick, which is a different shape from many pod kits and is worth knowing before you order if you prefer something slim. We cannot judge how it sits in the hand from a specification sheet, so we treat comfort as something to check in person rather than a selling point.
A lanyard loop is listed as an additional feature. For a device that people tend to carry on a neck cord or clip to a bag, a built-in loop is a practical touch that costs nothing extra and avoids the need for an adhesive accessory. It also hints at the intended use: a grab-and-go pod kit rather than a desk device.
Four colours are listed: Black, Blue, Red and Silver. Our product page describes them as classic, sleek, bold and minimalist respectively, which is marketing language rather than a technical difference, so choose on taste. All four are the same kit with the same specification.
Output, cartridges and coil options
The listing gives a maximum output of 25W. It does not say whether output is adjustable by the user or fixed by the cartridge, so we describe the figure only as a ceiling. The two cartridge options are FeCrAl meshed Caliburn G3 integrated coil cartridges in 0.6 Ω and 0.9 Ω, each with the coil built in. Mesh coils spread heat over a wider surface than a single wire, which is the general reason they are associated with flavour.
As a general rule, a lower resistance such as 0.6 Ω gives a warmer, denser vapour and uses more power, while a higher resistance such as 0.9 Ω gives a cooler, tighter draw at lower power. That is general guidance rather than a result from this kit, so use it as a starting point. Because the coil is integrated, you replace the whole cartridge when the coil wears out, which the listing describes as non-replaceable.
The cartridge holds 2.5 ml of e-liquid. That sits between small 2 ml pods and larger 3 ml cartridges, and it means a refill is needed a little less often than with a 2 ml pod. The listing does not say how fast the liquid is used, because that depends on your wattage, your draw length and the liquid you choose.
If you want spare cartridges, our Caliburn G3 and G3 Pro pods listing includes 0.6 Ω and 0.9 Ω options. Compare the cartridge name with the GK3 listing before you order, and see the pod compatibility finder if you are unsure.
Airflow, flavour technology and vaping style
The listing describes a dual airflow system. It does not explain exactly how the two airflow paths work, so we can only say that Uwell presents them as a way to customise each draw, from a tighter pull to a more open one. In practice, airflow and resistance work together: a 0.9 Ω cartridge with tighter airflow suits a cigarette-like pull, while a 0.6 Ω cartridge with more air gives a looser, airier one.
The listing does not use the terms MTL or RDL for this kit, so we avoid assigning the GK3 to either style as a fact. What it does state is the combination that creates the range: two cartridge resistances plus dual airflow. That is enough to give some flexibility from one body.
Pro-FOCS Flavor Tech is described as enhancing flavour production. It is a manufacturer claim about the coil design, and the listing gives no measurement behind it, so we report it as a feature rather than a result. What you taste will depend on the liquid, the cartridge and how you draw.
Battery, charging and portability
The built-in battery is 900 mAh and charges over Type-C with 2A fast charging, according to the listing. Our product page describes this as supporting long sessions, but no hour or puff figure is published, so we will not quote one. Real runtime depends on the cartridge, the wattage and how you draw, and higher power drains any battery faster.
Because 2A fast charging needs a suitable adapter to deliver its full rate, use a good quality phone-grade charger and a sound Type-C cable. A weak adapter still charges the device, only more slowly, which is easy to mistake for a fault.
Treat every lithium battery with care in UAE heat. Do not leave the device in a parked car, do not charge it under a pillow or on a sofa, do not charge it unattended overnight, and stop using any device that swells, leaks or becomes very hot. Refilling while the device is charging is also best avoided.
Portability is where the lanyard loop and compact body earn their place. The kit is designed to be carried, and the 900 mAh battery is sized to match the body rather than to maximise capacity. If you need all-day power from a single charge, a kit with a bigger battery is a safer choice.
How it compares with other Uwell kits
The table below compares the GK3 with three other Uwell kits we stock, using only figures from their listings. Every row in this UWELL Caliburn GK3 25W Pod Kit review comes straight from those listings, and anything a listing does not state has been left out rather than estimated.
| Device | Battery | Max output | Liquid capacity | Price |
|---|---|---|---|---|
| UWELL Caliburn GK3 25W Pod Kit (this review) | 900 mAh | 25W | 2.5 ml | AED 120 |
| Uwell Caliburn GK3 Tenet Pod Kit | 1000 mAh | 25W | 2.5 ml side-fill / 2 ml top-fill | AED 120 |
| Uwell Caliburn G4 Mini Pod System | 1100 mAh | 35W | 3 ml / 2 ml | AED 100 |
| Uwell Caliburn GK2 Pod System | 690 mAh | 18W | 2 ml | AED 110 |
The closest relative is the Uwell Caliburn GK3 Tenet pod kit review, which lists a 1000 mAh battery, a digital display and draw-activated operation at the same 25W ceiling. If you want more power and a bigger battery, the G4 Mini review linked above covers a 35W kit with a 1100 mAh battery. If you prefer something older and smaller, the Uwell Caliburn GK2 review covers an 18W kit with a 690 mAh battery.
Pods differ between Caliburn generations, so always match the pod to the kit. Our guide to choosing 0.9ohm and 1.2ohm pods for the Caliburn A2/A2S shows how that choice works on another Uwell family, and every model is on the Uwell brand page.
Cartridges, refilling and care in Dubai heat
A refillable kit is a small system rather than a single purchase. Alongside the device you need cartridges and e-liquid that suit the resistance you pick. Our pods and coils buying guide explains how resistance, airflow and liquid type work together, and the guide on how to change a vape coil helps you understand when a coil or cartridge has reached the end of its life.
Fill slowly, leave a little air at the top, and let a fresh cartridge rest for a few minutes before the first draw so the liquid can soak into the coil. That single step prevents most dry hits. The usual signs that a cartridge is finished are a burnt or muted taste, a gurgling draw or weak vapour that does not improve after priming. Replace it at that point rather than pushing power up to compensate.
Heat is a real factor in the UAE. Condensation and leaks are more likely when a pod kit is left in direct sun or a parked car, so keep the device in the shade, store liquid in a cool place and wipe the cartridge contacts with a dry cloth if liquid reaches them. The listing does not publish any leak-protection feature for the GK3, so we make no leak claim either way. For related cartridge reading, see the Uwell Caliburn X 3.0 ml empty pods review.
UAE rules, nicotine strength and safe use
Like every refillable pod kit, the GK3 ships without liquid, so the nicotine level depends entirely on what you add. Vape products sold in the UAE are expected to meet the UAE.S 5030:2018 standard (MoIAT), and the Ministry of Industry and Advanced Technology publishes the current requirements, including registration under the ECAS scheme. Check the official sources for the current rules and buy only from a licensed seller.
The World Health Organization states that electronic cigarettes are harmful to health and not safe. Nicotine is addictive. These devices are for adults aged 21 and over who already use nicotine, not for non-smokers, young people, or anyone who is pregnant or breastfeeding. UAE law may set a higher age limit than our own policy, and our age verification (21+) page explains how we check.

Price, delivery and our final verdict
The UWELL Caliburn GK3 Kit 25W is listed at AED 120 on our site at the time of writing. Our vape delivery in Dubai page and the delivery and payment terms hold the full details. In short, delivery is free above AED 350 and a flat AED 30 below that, so exactly AED 350 pays AED 30. The minimum order is AED 100, and this kit is listed above that on its own.
Dubai, Sharjah and Ajman orders are delivered in about 2 hours between 10am and 11pm, 7 days a week, with payment by cash, card or bank transfer. Other emirates receive courier delivery within 24 hours, Monday to Saturday, with cash on delivery or bank transfer. Delivery of vape products is for adults aged 21 and over.
Our verdict: a compact, portable pod kit with two cartridge resistances, dual airflow and fast charging, held back by a modest battery and a 25W ceiling. If those limits suit you, it is a sensible refillable choice. That is the bottom line of this UWELL Caliburn GK3 25W Pod Kit review, based on specifications rather than hands-on testing.

FAQ
Does the Uwell Caliburn GK3 come with nicotine?
No. It is a refillable device, so the strength is set by the registered e-liquid you choose to add. Check the label, buy from a licensed seller and remember the device is for adults aged 21 and over only.
Which cartridges does the GK3 use?
The listing names FeCrAl meshed Caliburn G3 integrated coil cartridges in 0.6 Ω and 0.9 Ω, each holding 2.5 ml. The coil is built into the cartridge, so the whole cartridge is replaced.
How is the GK3 charged?
It charges over Type-C with 2A fast charging. Use a suitable phone-grade adapter to get the full rate, because a weaker adapter charges more slowly.
Can I order it for delivery in the UAE?
Yes, it is listed on our store, with delivery to Dubai, Sharjah and Ajman in about 2 hours and courier delivery to other emirates within 24 hours. See the delivery pages linked above for the full terms and the AED 100 minimum order.
