When it comes to sleek, reliable pod systems, Uwell is a name vapers trust. Two of their most talked-about models—the Uwell Caliburn G2 vs G3—are often compared by beginners and experienced users alike. But which one is truly better?
In this article, we break down everything you need to know: design, performance, coil options, battery life, and more. Whether you’re upgrading your device or buying your first pod system, this guide will help you decide between the G2 and G3.
Introduction to Uwell Caliburn Series
The Caliburn line by Uwell has earned a strong reputation in the vaping community. Known for its slim design, smooth MTL (mouth-to-lung) draw, and great flavor, each release improves on the last.
Both the Caliburn G2 and G3 are compact, user-friendly pod systems. Yet, subtle differences in design, features, and functionality can make or break your vaping experience. Let’s explore them side by side.
Design and Build Quality
Sleekness and Form Factor
The Caliburn G2 has a more classic pen-style shape with slightly curved edges, offering a comfortable grip. It’s lightweight, discreet, and easy to pocket.
On the other hand, the Caliburn G3 is even sleeker. It features a flat body with a more refined aesthetic, geared toward vapers who want a modern, minimalist look.
Display and Buttons
The G2 uses a single fire button and LED light indicator for battery status. In contrast, the G3 introduces a small OLED display that shows battery level, wattage, and puff count—an upgrade for those who want more control.
Pod and Coil System
Coil Compatibility and Installation
One of the biggest differences between the Uwell Caliburn G2 vs G3 lies in their coil systems.
- Caliburn G2 uses replaceable coils. You can swap between 0.8Ω and 1.2Ω coils depending on your vaping preference.
- Caliburn G3, however, moves to fixed-coil pods. While this simplifies the process, it limits flexibility.
For some, fixed coils are more convenient—just replace the pod when flavor fades. But others may prefer the cost-efficiency and customizability of replaceable coils.
Pod Capacity and Fill Method
Both models support 2ml e-liquid capacity, suitable for nicotine salts and MTL vaping. The G2 uses a top-fill system under the mouthpiece, which is leak-resistant and easy to use. The G3 continues this top-fill tradition but refines it for quicker refills.
Airflow Adjustment
A feature many vapers care about is adjustable airflow.
The Caliburn G2 shines here with a precise wheel under the pod that lets you tweak the draw to your liking—tight MTL or a looser pull.
The Caliburn G3, surprisingly, lacks airflow control. It offers a consistent draw, but that might not suit users who want to fine-tune their inhale.
Battery Life and Charging
Capacity and Daily Usage
Battery life is crucial, especially for daily vapers. The Caliburn G2 has a 750mAh battery, which easily lasts a full day with moderate use.
The G3 improves this with a 900mAh battery. Combined with its smart chipset, it delivers more efficient power usage and slightly longer battery life overall.
Charging Speed
Both devices support USB Type-C charging, with the G3 having faster charging capabilities. Expect full charges in under 45 minutes.
Performance and Flavor Quality
Vapor Production
In terms of vapor, both models are impressive for their size. The G2, with its lower-resistance coils, produces warm vapor and satisfying clouds. The G3 is a touch smoother, offering consistent output thanks to its upgraded chipset.
Flavor Delivery
Uwell is known for its Pro-FOCS flavor technology, and both models benefit from it. However, the G3 provides slightly better flavor clarity—especially noticeable with fruit or dessert profiles.
Still, for most vapers, both offer excellent flavor delivery from start to finish.
User Experience and Convenience
Ease of Use
The Caliburn G2 offers manual or auto-draw operation. You can press the button or simply inhale—your choice. The G3 removes the button entirely, offering a purely auto-draw experience, which is more beginner-friendly.
Display Features
The G3’s OLED screen gives it an edge. You can monitor battery life, wattage, and puff count at a glance—handy if you want more insight into your vaping habits.
Value for Money
In terms of price, both are affordable, but the G2 typically comes at a lower cost. However, over time, the G3’s fixed-coil pod replacements may add up.
If you’re someone who prefers swapping out coils instead of full pods, the G2 might save you more in the long run.
Final Verdict: Uwell Caliburn G2 vs G3
So, which one should you choose?
- Choose the Caliburn G2 if you want airflow control, coil flexibility, and a traditional vaping experience.
- Choose the Caliburn G3 if you prefer simplicity, longer battery life, and a more modern design with display features.
Both devices are excellent, but your decision comes down to what matters most—customization or convenience.
