A Deep Dive into Performance and Features
If you’re searching for a compact and reliable pod vape, you’ve probably come across the Uwell Caliburn G2. Since its launch, this device has gained significant attention in the vaping community. In this Uwell Caliburn G2 review, we’ll break down everything from design and build quality to flavor performance and battery life.
Let’s find out if the G2 is still a top contender in 2025.
Design and Build Quality
The Uwell Caliburn G2 continues the sleek, minimalist design that Caliburn fans have come to expect. It’s lightweight, comfortable in hand, and made from durable aluminum alloy.
Ergonomics and Portability
Weighing just under 40g, the G2 is one of the most portable pod systems out there. It fits easily in your pocket or bag, making it ideal for on-the-go use. The mouthpiece is curved and more comfortable than previous models, providing a pleasant MTL (mouth-to-lung) experience.
Construction and Materials
Uwell has maintained high standards with this device. The G2 is solid, without any loose parts. The magnetic pod connection snaps firmly in place, and the airflow wheel feels smooth yet secure.
Performance and Flavor Quality
Arguably, the most important aspect of this Uwell Caliburn G2 review is how well it performs. Spoiler alert: it’s impressive.
Pro-FOCS Flavor Technology
Uwell’s Pro-FOCS (Professional Flavor Optimizing Core System) delivers rich, saturated flavor. Whether you use freebase or nicotine salts, the G2 provides consistent vapor and taste.
Coil Compatibility
The G2 is compatible with Caliburn G-series coils. It comes with two:
- 1.2Ω for tighter, smoother MTL draws
- 0.8Ω for a warmer, slightly looser hit
Both coils work well, but the 0.8Ω gives better cloud production and deeper flavor, especially for fruit or dessert e-liquids.
Adjustable Airflow
The standout feature here is the precise adjustable airflow wheel. Unlike other pod systems that offer preset airflow, the G2 lets you fine-tune your draw. It’s a big upgrade, especially for vapers who like control over their experience.
Pod and Filling System
One of the most common complaints with pod systems is leaking or difficult refilling. The G2 addresses both.
Leak-Resistant Design
The pod features improved sealing around the fill port and coil base. During our testing, we didn’t experience any significant leaking, even when left overnight.
Top-Fill Mechanism
Filling the G2 is a breeze. Just remove the mouthpiece to access the red silicone fill port. This design prevents messes and allows quick refills, even one-handed.
The pod holds 2ml of e-liquid, which is standard for TPD compliance and enough to last a full day for moderate users.
Battery Life and Charging
The G2 features a 750mAh battery, which is slightly larger than the original Caliburn and G series.
Real-World Battery Performance
On average, the battery lasts about 1.5 days with moderate use. If you’re using the 1.2Ω coil and vaping casually, you might even stretch it to two days.
Fast Type-C Charging
With USB-C fast charging, the device recharges fully in about 45 minutes. That’s a win for users who don’t want to wait around.
Ease of Use and User Experience
Uwell has kept the G2 simple and intuitive.
Draw or Button Activation
You can vape by either pressing the fire button or simply inhaling. Both methods are responsive and reliable. This dual activation style appeals to both new and experienced users.
LED Battery Indicator
The color-coded LED light shows battery level at a glance:
- Green: High
- Blue: Medium
- Red: Low
It’s a small touch, but it enhances usability without a screen.

Comparison with Other Caliburn Models
Wondering how it stacks up against others in the Caliburn lineup?
The G2 bridges the gap between the Caliburn G and Caliburn A2. It offers the versatility of replaceable coils and the simplicity of top-fill pods. Unlike the A2, you get adjustable airflow, and unlike the G, you benefit from better coil options and pod sealing.
If you’re deciding between models, the G2 delivers the most balanced experience without sacrificing flavor or portability.
