My Ultimate Pod Mod Kit Showdown: Uwell Caliburn GZ2 vs. Caliburn AZ3

The Caliburn GZ2 and AZ3 Pod Mod Kit Go Head to Head

Today, I’m excited to share my in-depth review of not one but two fantastic Uwell pod mod kits: the Caliburn GZ2 and the Caliburn AZ3. Both promise to deliver exceptional vaping experiences, but let’s see how they stack up against each other.

Design and Build Quality: Caliburn GZ2 & AZ3

My Ultimate Pod Mod Kit Showdown: Uwell Caliburn GZ2 vs. Caliburn AZ3

Starting with the Caliburn GZ2, this sleek and slender device is hewn from durable and lightweight aluminum-alloy, making it the perfect companion for those always on-the-go. Its dimensions of 68.9mm by 23.8mm by 23.6mm make it pocket-friendly and easy to handle. The build quality is excellent, and I can tell that Uwell put effort into making this device feel premium.

On the other hand, the Caliburn AZ3 shares a similar form factor with its sibling, also crafted from sturdy aluminum-alloy. It fits snugly in the palm of my hand, and at 68.9mm by 23.8mm by 23.6mm, it’s just as portable as the GZ2. The build quality on the AZ3 is equally impressive, giving me confidence in its durability.

Battery Capacity and Charging of the Caliburn GZ2 & AZ3

The Caliburn GZ2 comes equipped with an 850mAh battery, ensuring that it lasts throughout the day without a hitch. Its 17W max output provides enough power to produce dense clouds and delicious flavor from my favorite e-juices. The Type-C charging port is a welcome addition, allowing for faster and more convenient recharging.

The Caliburn AZ3 features a slightly smaller 750mAh battery, which might mean a little less vaping time compared to the GZ2. However, it’s still adequate for a full day’s use for moderate vapers. Like the GZ2, it also supports a 17W max output, and the Type-C charging ensures quick and efficient charging sessions.

Pods and Coils:

Both kits use refillable pods, and they each come with two pods in the package. The Caliburn GZ2 pods, known as Caliburn G2 Pods, have a capacity of 2mL, while the Caliburn AZ3 pods, referred to as Caliburn A3 Pods, also hold 2mL of e-liquid. Both pods are made from PCTG, a durable and food-grade material.

The Caliburn GZ2 pods utilize the Caliburn G Coils, which are known for their flavor production and longevity. The package includes a 0.8ohm and a 1.2ohm coil, giving vapers the option to choose their preferred vaping style.

In contrast, the Caliburn AZ3 pods have integrated coils, which means you replace the entire pod when the coil needs changing. This can be convenient for some users who prefer a hassle-free experience.

Performance and Flavor for the Caliburn GZ2 & AZ3

When it comes to performance, both the GZ2 and AZ3 deliver smooth draws and satisfying vapor production. The draw-activated firing systems on both devices make them user-friendly, with no need to fuss with buttons.

In terms of flavor, it’s a close call. The Caliburn G Coils on the GZ2 provide rich and flavorful vapor that keeps me coming back for more. The integrated coils on the AZ3 may not match the GZ2’s coils in flavor intensity, but they still deliver impressive taste and vapor quality.

LED Indicator Light:

Both devices feature an LED indicator light that shows battery life and provides status notifications. This simple yet effective feature helps me keep track of my battery levels, ensuring I’m never caught off guard.

Final Thoughts on the Caliburn GZ2 & AZ3:

In the end, the choice between the Uwell Caliburn GZ2 and the Caliburn AZ3 comes down to personal preference. If you value the flexibility of choosing different coils and prefer the slightly larger battery, the GZ2 might be your best bet. On the other hand, if you’re looking for a more straightforward, coil-integrated system and don’t mind a slightly smaller battery, the AZ3 could be a perfect match.

Both kits are well-built, offer great flavor, and are highly portable. So, whichever one you choose, you’re in for a delightful vaping experience. Happy vaping, folks!
