The world of pod vaping continues to evolve with every new release, and Uwell’s Caliburn G series has consistently set benchmarks for performance, design, and flavour.
The Uwell Caliburn G3 Pod Vape Kit is no exception — it’s a modernised upgrade tailored for both MTL (mouth to lung) and RDL (restricted direct to lung) vaping styles. Compact, powerful, and stylish, the G3 has been engineered to serve the needs of beginners transitioning from disposables, as well as more experienced users seeking a high-performance daily driver.
In this in-depth review, we explore every aspect of the Caliburn G3 — its design, features, performance, and why it’s one of the most talked-about pod systems of 2025.
Since the original Caliburn burst onto the vaping scene, Uwell has built a reputation for delivering intuitive and reliable pod systems. The G3 continues this legacy, but with a bolder focus on power and user control. It features a built-in 900mAh battery, variable wattage up to 25W, and refillable pods equipped with mesh coils for enhanced flavour delivery.
The G3 introduces a user-friendly OLED display, dual activation modes (draw or button), and adjustable wattage — features typically reserved for more advanced devices. But thanks to its clean interface and ergonomic design, it remains incredibly accessible to newer vapers.
At first glance, the G3 is sleek and minimalistic. Constructed from a mix of aluminium alloy and durable PCTG plastic, it weighs only 47g, making it a lightweight yet solid-feeling device. Measuring 120mm in height, 24mm in width, and 13.9mm in depth, it easily fits in your hand or pocket.
The G3 is available in multiple stylish colours, each finished with a soft matte sheen that resists fingerprints and offers a premium feel. The curved edges and slightly rounded corners make it comfortable to grip over extended sessions.
One of the standout features of the G3 is its OLED display showing all the essential data at a glance: wattage, resistance, puff count, battery level, and mode. The screen is clear and bright, even in outdoor lighting.
Navigation is handled through a single multifunctional button. This button powers the device on/off, cycles through wattage settings, and can be used to switch between draw or button activation.
Simplicity is key here — the Caliburn G3 doesn’t overload you with menus, yet still provides excellent control over your vaping experience.
With its 900mAh battery, the Caliburn G3 is more than capable of lasting a full day for most users. Moderate to heavy vapers can expect around 2–3 pod refills before needing a charge, depending on the wattage and coil resistance used.
Charging is done via USB-C, a welcome feature that ensures fast and efficient charging. A full recharge typically takes under 45 minutes, making it practical for on-the-go lifestyles. The pass-through charging feature allows you to vape while it’s plugged in — ideal for long commutes or breaks.
The G3 comes with two refillable pods, each with 2ml capacity and and a built-in coil:
These pods integrate Uwell’s Pro-FOCS flavour technology, which enhances coil heating consistency and e-liquid atomisation. The result is crisp, clean, and true-to-profile flavour delivery.
Whether you prefer freebase nicotine or nicotine salts, the G3 handles both with ease. The mesh design ensures even heating, longer coil life, and dense vapour. Expect each pod to last anywhere from 5 to 8 full refills depending on your usage and e-liquid viscosity.
Filling the G3 pods is as easy as it gets. The top-fill design means you don’t need to remove the pod from the device. Simply pop off the mouthpiece to reveal the filling port. This not only minimises leakage and mess but also speeds up the refilling process when you’re out and about.
The leak-resistant structure of the pods helps prevent e-liquid build-up in the contacts — a common problem in cheaper pod systems. This makes the G3 ideal for those who need a dependable device they can throw into a pocket or bag without worry.
While the G3 doesn’t have an external airflow adjustment slider, it cleverly adjusts airflow based on the pod used. The 0.9Ω pod delivers a tighter MTL experience, closely mimicking the draw of a traditional cigarette — making it perfect for those transitioning from smoking.
Switch to the 0.6Ω pod, and you’ll enjoy a looser RDL vape with a noticeable increase in vapour output and airflow. It’s not quite cloud-chasing territory, but it’s more than enough for flavourful, satisfying hits.
Shop G3 PodsSome vapers prefer the immediacy of draw-activation, while others like the deliberate feedback of a fire button. With the G3, you can switch between the two. It’s a thoughtful inclusion that allows users to tailor the experience based on their preferences.
The draw activation is responsive and consistent, while the fire button gives more precise control, especially useful when testing new wattages or breaking in a fresh pod.
The G3 hits the sweet spot for a broad range of users:
Travellers: The compact size, USB-C charging, and leak-proof design make it ideal for vaping on the go.
Its versatility, durability, and performance make it a top pick for 2025 across all user levels.
