Uwell Caliburn G2 Review – MTL & Sub-Ohm Performance
When it comes to pod systems, Uwell has consistently raised the bar for both mouth-to-lung (MTL) and sub-ohm experiences. The Uwell Caliburn G2 stands as a testament to that legacy, offering a hybrid device capable of delivering satisfying hits to both casual and seasoned vapers. Whether you’re after the familiar pull of a cigarette-style MTL vape or the fuller, cloudier sub-ohm sensation, this device promises to cater to your preferences. But does it truly deliver on both fronts, especially when it comes to the much-hyped Uwell Caliburn G2 sub-ohm capabilities? In this review, we dig deep into the real-world performance, design, coil versatility, and battery life to help you decide if this is the next device for your pocket.
Design and Build Quality
Uwell has always prioritized sleekness, and the Caliburn G2 doesn’t stray from that path. It comes in a slim aluminum alloy body with a satin finish that feels premium without adding unnecessary weight. The curved mouthpiece fits naturally against the lips, while the responsive fire button and precise airflow wheel underneath the pod add extra functionality. Holding the device feels comfortable, and the build is solid. The magnetic pod connection is secure, ensuring that the pod doesn’t wiggle or pop out in your pocket.
Performance Overview
The Caliburn G2’s performance is where things get interesting. Equipped with an upgraded haptic feedback system and a refined airflow control mechanism, this device is engineered for both MTL and sub-ohm vaping styles. What really makes the Uwell Caliburn G2 sub-ohm performance stand out is its compatibility with multiple coil types, allowing users to switch styles without changing devices. This flexibility is rare in such a compact form factor.
Coil Options and Vaping Experience
The G2 supports Uwell’s G-series coils, specifically the 0.8Ω mesh and the 1.2Ω coils. For those seeking sub-ohm performance, the 0.8Ω coil offers a rich, warm vape with enhanced vapor production, perfect for users who enjoy fuller clouds and more flavor intensity. It’s well-optimized for high VG e-liquids, although 50/50 ratios also perform decently. The 1.2Ω coil, on the other hand, delivers an ideal MTL draw with tighter airflow and a more focused nicotine hit. What’s impressive is how easily you can swap between these two styles without any fuss—just pop in the coil of your choice, adjust the airflow using the red wheel beneath the pod, and you’re good to go.
Airflow Customization
Airflow control has always been a crucial element in vaping satisfaction. With the Caliburn G2, Uwell introduces a more tactile, user-friendly airflow wheel. Unlike its predecessor, the G2 lets you fine-tune the resistance of your draw—whether you want it tight and cigarette-like or airy and sub-ohm-ready. This airflow control directly influences your Uwell Caliburn G2 sub-ohm experience by letting you tailor the vapor density and temperature to your preference. The ability to transition from restricted MTL to loose DTL-style pulls makes this device highly versatile.
Battery Life and Charging
With a 750mAh built-in battery, the Caliburn G2 offers a full day of moderate usage on a single charge. That’s quite decent for a device this compact. For sub-ohm users, however, the battery may not last as long due to the higher power demand of the 0.8Ω coil. Even so, Uwell balances this by offering fast USB-C charging, allowing a full recharge in under 45 minutes. The LED indicator light changes color to show battery levels—green for high, blue for medium, and red for low—so you’re never caught off guard.
E-Liquid Capacity and Filling
The pod comes with a 2ml e-liquid capacity, which is standard but sufficient for nicotine salts and freebase liquids. The top-fill design is pressure-activated, meaning you pop off the drip tip to access the fill port. It’s leak-resistant and easy to use. Though heavier vapers may need to refill more frequently, the process is clean and quick. The pod transparency also lets you monitor your juice level easily, avoiding unpleasant dry hits.
Flavor Production
Uwell’s Pro-FOCS flavor testing technology really shines here. Whether you’re using the MTL 1.2Ω coil or the sub-ohm 0.8Ω coil, flavor notes come through crisp, layered, and consistent. The mesh design in the sub-ohm coil enhances surface contact with the e-liquid, providing more intense and nuanced flavor profiles. This becomes evident especially with dessert or fruit-based e-liquids, where the Caliburn G2 outperforms many pod systems in the same category.
Pros of Uwell Caliburn G2
The Caliburn G2 excels in adaptability. It’s ideal for users who want to try sub-ohm vaping without investing in larger box mods. Its dual-coil compatibility, smooth airflow adjustment, and flavorful output give it an edge over most single-purpose pod systems. The USB-C charging and haptic feedback also bring modern touches to a market still dominated by micro-USB devices.
Cons of Uwell Caliburn G2
No product is perfect. One notable drawback is the battery capacity, especially for sub-ohm users who may find themselves charging it more often. Additionally, the fill port, while improved, still requires the removal of the mouthpiece, which some might find inconvenient. Lastly, the device lacks wattage control, which could have given more advanced users additional flexibility.
Who Should Buy the Caliburn G2?
If you’re a smoker transitioning to vaping, the G2’s MTL performance mimics the draw of a cigarette, making it an excellent starter kit. If you’re a current vaper looking to experiment with Uwell Caliburn G2 sub-ohm functionality without diving into complex vape mods, this device gives you a solid introduction. It suits users who value portability but don’t want to compromise on flavor or cloud production.
Real-World Usage and Durability
Users report that the Caliburn G2 holds up well with daily use. Coil longevity averages around 10–14 days, depending on the e-liquid and vaping habits. The haptic feedback is subtle but useful, indicating when the pod is connected or when the battery is low. The aluminum body resists minor scratches and drops, making it durable enough for everyday carry.
Comparison with Other Devices
When compared to devices like the Vaporesso XROS or Smok Nord series, the G2 stands out for its flavor quality and MTL comfort. While the Nord provides more sub-ohm coil options, the G2 offers a better balance between flavor and ease of use. The XROS is similar in size and function but lacks the haptic feedback and the refined airflow wheel that sets the Caliburn G2 apart.
Final Verdict
The Uwell Caliburn G2 proves to be a worthy upgrade in the Caliburn series, providing a unique balance between simplicity and performance. It truly bridges the gap between MTL and sub-ohm vaping, making it suitable for a wide audience. If you’re looking for a device that delivers excellent flavor, easy coil swapping, and customizable airflow—all in a sleek, portable form—the G2 deserves a spot in your lineup.
