Uwell Caliburn G2 Review – A Balanced Pod Vape
The Uwell Caliburn G2 is one of the most talked-about pod vapes among beginners and seasoned vapers alike. Known for its sleek design, upgraded features, and satisfying performance, the G2 aims to strike a balance between portability, power, and flavor.
In this review, we’ll break down everything you need to know about the Uwell Caliburn G2—from how it feels in your hand to how it performs under daily use. Whether you’re considering switching from disposables or upgrading your current device, this guide will help you make an informed decision.
First Impressions: Design and Build Quality
From the moment you unbox the Uwell Caliburn G2, it’s clear that this isn’t just another pod vape. The device boasts a refined aluminum alloy body that feels light yet durable. It’s compact enough to slip into your pocket, yet long enough to feel comfortable in the hand.
The curved edges give it a modern, ergonomic feel. The most noticeable change from previous versions is the newly integrated e-liquid viewing window, allowing you to monitor juice levels without removing the pod. This simple yet helpful upgrade reduces dry hits and enhances usability.
Pod and Coil System: Tailored for Flavor
One of the standout features of the Uwell Caliburn G2 is its upgraded pod and coil system. It supports replaceable coils, a feature that adds long-term value and customization.
Reversible Airflow Control
Unlike its predecessors, the G2 introduces a wheel-based airflow adjustment system built into the pod. This allows for precise control, making it suitable for both Mouth-to-Lung (MTL) and Restricted Direct Lung (RDL) vaping styles. It’s a subtle but impactful innovation that truly makes a difference in daily use.
Coil Options
The Caliburn G2 supports Uwell’s UN2 Meshed-H coils, available in 0.8Ω and 1.2Ω resistances. The 0.8Ω coil delivers warmer vapor and richer flavor, ideal for those who prefer a tighter draw. On the other hand, the 1.2Ω coil offers a cooler, smoother hit—perfect for salt nicotine lovers.
Uwell’s Pro-FOCS Flavor Technology also plays a role here. It recycles the air drawn in, enhancing flavor while extending coil life. As a result, flavor remains consistent from the first puff to the last.
Battery Life and Charging
Equipped with a 750mAh built-in battery, the Caliburn G2 easily lasts a full day for moderate users. While heavy users might find themselves charging it mid-evening, the quick USB-C charging ensures you won’t be tethered for long.
From 0% to full charge, expect around 40-45 minutes—ideal for users who vape throughout the day but need a reliable top-up during breaks.
Performance and Vaping Experience
The real test of any pod system is how it performs when used consistently. Fortunately, the Uwell Caliburn G2 excels in this category. Whether you’re using freebase e-liquid or nicotine salts, the G2 provides a smooth, flavorful experience with each puff.
Draw Activation and Button Firing
One of the features that makes the G2 versatile is the dual firing system. You can either press the button or simply draw on the mouthpiece. This allows you to tailor the experience to your liking, offering both convenience and control.
Vapor Production
While the Caliburn G2 isn’t built for cloud chasing, it delivers a respectable amount of vapor—more than enough to satisfy ex-smokers and casual vapers. The vapor is dense, warm, and carries flavor exceptionally well, especially with the 0.8Ω coil.
No Leaking or Spitback
Another strong point is how the G2 handles e-liquid. The pod snaps in securely, and the top-fill system minimizes mess. Over several weeks of testing, there were no issues with leaking or spitback, which is a common concern with pod systems.
Ease of Use: A Beginner-Friendly Device
Whether you’re a newcomer or someone returning to vaping, the Caliburn G2 scores high in terms of user-friendliness. The top-fill design reduces the chances of spilling juice, while the viewing window keeps you in control. The magnetic pod connection ensures a solid fit without fumbling.
There’s also a vibration feedback system, which alerts you when the pod is inserted or when there’s a problem—like a short circuit or a dry hit risk. These subtle cues go a long way in making the G2 intuitive to use.
Durability and Longevity
With regular care, the Caliburn G2 can last for months. The aluminum body resists scratches, and the pods hold up well even after multiple refills. Coil life varies depending on usage, but you can expect 7–10 days of peak performance per coil, which is above average for devices in this category.
