Price

The Caliburn GK2 typically comes with a price tag of around $40, which places it in the mid-range category of vaping devices. Now, some might argue that you can find cheaper alternatives out there, while others might consider this price point reasonable for what the GK2 has to offer.

In my experience, the $40 price point strikes a good balance between affordability and quality. When you invest in the Caliburn GK2, you’re not just buying a vaping device; you’re investing in a piece of cutting-edge technology that delivers on both style and performance.

Let’s break it down further. For this price, you’re getting a device that boasts a fashionable design, enhanced functions, and the innovative UWELL Pro-Focs flavor adjustment technology. The device’s cyberpunk and steampunk design elements alone make it stand out in the market. It’s like owning a collector’s item, and that uniqueness adds intrinsic value.

Additionally, the GK2 offers a maximum output of 18W, a 2ml cartridge capacity suitable for both Nic Salt and Freebase e-liquids, and a top-filling system for easy refills. These features contribute to a seamless and enjoyable vaping experience, which is priceless for many enthusiasts.

Now, let’s talk about the battery life. With a 690mAh built-in battery, the GK2 ensures that you can enjoy your vape sessions for extended periods between charges. I’ve found it to be reliable, providing me with hours of vaping without any significant drop in performance. That reliability is worth its weight in gold, especially when you’re on the go.

But what about the cons? Well, it’s essential to be honest in my assessment. Some vapers might be put off by the device’s LED lights, which, while adding to its futuristic charm, might not suit those who prefer a more discreet vaping experience. However, I see it as a small trade-off for the unique design and overall excellence of the GK2.

Design&Quality

Let’s start with the basics—the size and shape. The Caliburn GK2, in many ways, resembles its predecessor, the Koko Prime. However, upon closer inspection, I noticed some subtle yet significant design improvements. The edges are smoother, giving it a more refined and comfortable feel in hand. It’s not just about looks; it’s about ergonomics, and the GK2 gets it right.

One of the standout features of the Caliburn GK2 is its size and weight. Weighing in at just 45.2 grams, it’s an incredibly lightweight device. As a vape reviewer, I’ve had my fair share of hefty devices, and the GK2’s feather-light build is a breath of fresh air. It’s the kind of device that you can effortlessly slip into your pocket without even noticing it’s there.

Now, let’s talk about the material. Uwell has opted for a durable zinc alloy for the GK2’s construction. This choice is a game-changer, especially for vapers like me who tend to be a bit clumsy. The zinc alloy not only adds to the device’s overall durability but also gives it a premium feel. It’s the kind of material that ensures your device can withstand the rigors of everyday life.

But here’s where the Caliburn GK2 truly shines in the convenience department—the included lanyard. It may seem like a small detail, but it makes a world of difference. I can’t tell you how many times I’ve misplaced or dropped my vape, only to scramble to find it. With the lanyard, that problem is a thing of the past. It’s a simple addition that shows Uwell’s commitment to making the GK2 a user-friendly device.

The lanyard not only adds a layer of convenience but also enhances the device’s portability. It’s like having your vape on a leash, ready to be used whenever and wherever you need it. Whether you’re out for a walk, at a social gathering, or simply running errands, the GK2 ensures that your vape is always within arm’s reach.

The aesthetics of the Caliburn GK2 aren’t just about looks; they’re about the overall user experience. Uwell has paid attention to the details, from the design improvements to the lightweight build and the inclusion of the lanyard. It’s a device that not only performs exceptionally but also fits seamlessly into your daily life.

In my personal experience, the appearance and design of a vaping device matter more than you might think. It’s about how the device feels in your hand, how easy it is to carry, and how confident you feel while using it. The Caliburn GK2 ticks all the right boxes in these aspects, making it a device that I can wholeheartedly recommend to both experienced vapers and newcomers to the vaping world.

Battery and Charging

First and foremost, the Caliburn GK2 is equipped with a 690mAh built-in battery. Now, what does this mean for your vaping experience? In my time with this device, it meant longer hours between charges and consistent performance. As an avid vaper and vape reviewer, having a reliable battery is a top priority for me, and the GK2 did not disappoint.

Throughout my testing, I found that the 690mAh battery capacity provided ample power to keep me vaping for extended periods. It’s well-suited for those who enjoy a Mouth To Lung (MTL) vaping style, delivering a satisfying vaping experience without the constant need for recharging. Plus, with its fast charging capability, I never had to wait long to get back to vaping once the battery ran low. It’s a convenience that any vaper can appreciate.

Now, let’s talk about the unique features that set the Caliburn GK2 apart—the LED lights and vibration interaction. These elements not only add a futuristic touch to the device but also serve practical purposes.

The LED lights on the GK2 serve as a visual indicator of the device’s status. They change colors at different power levels, providing you with real-time information about your battery’s charge. When the battery is running low, the LED lights turn red, signaling that it’s time for a recharge. Conversely, when the device is fully charged, the lights turn green. This feature is not only useful but also adds a touch of style to your vaping experience.

But that’s not all—the Caliburn GK2 takes user interaction a step further with its vibration feature. The device vibrates to indicate different working states. Whether it’s a low voltage warning, an overtime alert, an open circuit warning, or even when you’re installing a new cartridge, the GK2 communicates with you through subtle vibrations. It’s a level of interaction that enhances the overall user experience.

During my time with the GK2, I found the LED lights and vibration interaction to be more than just gimmicks; they were genuinely helpful. The lights gave me instant feedback on the battery’s status, eliminating any guesswork, and the vibrations ensured that I never missed an important alert. It’s the kind of attention to detail that sets the device apart.

Features  

The Caliburn GK2 boasts a maximum 18W output. This power level is perfect for those looking to achieve satisfying vapor production without going overboard. During my time with the device, I found that it strikes a balance between cloud production and flavor intensity, making it versatile for various vaping preferences.

The GK2 comes with a 2ml cartridge, which is ideal for both Nic Salt and Freebase e-liquids. This flexibility allows vapers to choose their preferred type of e-liquid without any limitations. Whether you’re into the smooth throat hit of Nic Salt or the bold flavors of Freebase, the GK2 has you covered.

One standout feature that greatly enhances the overall user experience is the top-filling system. Refilling your e-liquid has never been easier. With just a simple push, you can access the fill port, allowing you to refill quickly and without any mess. It’s a feature that I particularly appreciated when I was on the go and needed a convenient way to top up my e-liquid.

Another practical feature is the transparent e-liquid window. This window provides a clear view of your e-liquid level at all times. It eliminates the guesswork and ensures that you’re never caught off guard with an empty tank. It’s a small but incredibly useful detail that speaks to Uwell’s commitment to user-friendly design.

In terms of build and materials, the Caliburn GK2 shines. It’s constructed using lightweight materials that not only contribute to its pocket-friendly build but also offer a comfortable grip. This device weighs in at only 45.2 grams, making it virtually unnoticeable in your pocket. As someone who values portability and ease of use, I was thoroughly impressed by its design and build quality.

The GK2 comes in a variety of eye-catching colors, offering five different options. Whether you prefer a classic look or want to make a bold statement with your vape device, there’s a color to suit your style. It’s a small touch that adds a touch of personalization to your vaping setup.

One of the standout features for me was the precise airflow adjustment. With the adjustment wheel, you have complete control over your airflow preferences. Whether you prefer a tight MTL draw or a more open and airy vape, the GK2 can accommodate your preferences with ease. It’s a level of customization that allows you to fine-tune your vaping experience to perfection.

Finally, let’s talk about coil compatibility. The Caliburn GK2 is compatible with various CALIBURN G series coils, including the CALIBURN G2 1.2? mesh coil, CALIBURN G 0.8? mesh coil, and CALIBURN G 1.0? coil. The versatility in coil options means that you can explore different vaping styles and find the one that suits you best. During my testing, I tried each of these coils, and they all delivered exceptional flavor and vapor production.

My personal experience with the Uwell Caliburn GK2’s features has been nothing short of fantastic. It combines a satisfying 18W output with a 2ml cartridge capacity for versatility in e-liquids. The top-filling system and transparent e-liquid window make refilling a breeze, while the lightweight build and color options add style and portability.

Performance

The Caliburn GK2 is designed with simplicity in mind. It doesn’t have any buttons to fiddle with; instead, it relies solely on puff-sensor activation. This means that all you need to do is take a puff, and the device instantly responds. It’s incredibly intuitive and user-friendly, making it an excellent choice for both beginners and experienced vapers.

One notable feature is the absence of a screen and adjustable wattage. While some devices offer extensive customization options, the Caliburn GK2 takes a different approach. It offers a maximum wattage of 18W, which is more than sufficient for a satisfying vaping experience. The wattage is adaptable based on the installed Caliburn G series coil, ensuring that you get the performance you desire without any complicated settings.

During my time with the device, I had the opportunity to test both the 0.8? and 1.2? coils included in the kit. These coils are well-suited for MTL (Mouth To Lung) vaping, providing a smooth and enjoyable vaping experience. I particularly appreciated their compatibility with 50/50 salt or freebase nicotine liquids, which allowed me to choose my preferred e-liquids without restrictions.

Changing the coils is a straightforward process. You simply pull the pod out of the device, locate the coil at the bottom of the pod, remove the old one, and insert the new one. It’s a quick and hassle-free procedure that doesn’t require any technical know-how. This ease of coil replacement ensures that you can always enjoy a fresh and flavorful vape without any fuss.

Another user-friendly aspect is the pod refilling mechanism. It’s designed for convenience, allowing you to refill the 2ml pod with ease. To do so, you just need to push back on the mouthpiece until it’s removed and then insert the bottle nib through a small red seal on the top of the pod. It’s a hassle-free method that minimizes spills and messes, ensuring that you can top up your e-liquid quickly, even when you’re on the move.

The Caliburn GK2 delivers exceptional flavor and vapor production, and I attribute this to Uwell’s Pro-FOCS technology. This technology includes a self-cleaning feature that keeps the coil fresher for longer, ultimately enhancing the flavor you experience. Throughout my testing, I tried a variety of e-liquids, and each one delivered a consistently satisfying flavor profile.

Most importantly, the Caliburn GK2 excels in delivering exceptional flavor and vapor production, thanks to Uwell’s Pro-FOCS technology. If you’re in search of a vape device that prioritizes ease of use and performance, I wholeheartedly recommend giving the Caliburn GK2 a try. It’s a device that simplifies vaping without compromising the quality of your vaping experience.

Verdict

In my final verdict on the Uwell Caliburn GK2, I must say that this device has truly impressed me with its overall performance and user-friendly features.

Weighing in at just over 45 grams, it’s incredibly easy to carry around, and the included lanyard adds an extra layer of convenience, preventing you from misplacing your vape. The sleek and modern design, coupled with the cyberpunk-inspired light bars, gives it a unique and eye-catching look.

Caliburn GK2 offers a satisfying vaping experience. It’s powered by a 690mAh built-in battery, which not only lasts for a decent amount of vaping but also charges up quickly, in about an hour or so. You won’t find yourself running out of battery in the middle of the day.

The LED lights and vibration interaction add a fun and futuristic element to the device. The lights change colors at different power levels, indicating when it’s time to charge. However, it’s worth noting that the lights may not be ideal for stealth vaping, as there isn’t an option to turn them off.

While the LED lights may not suit those who prefer stealth vaping, they add a touch of flair to the device. The approximate price of $40 is reasonable for the performance and features offered.

I wholeheartedly recommend considering the Uwell Caliburn GK2 if you value ease of use and exceptional performance. It’s a device that simplifies the vaping process without compromising on the quality of your vape.
