Uwell Caliburn Series Review: Which One is Worth It?
The Uwell Caliburn series has become a household name among vaping enthusiasts. Known for their sleek design, excellent flavor output, and user-friendly nature, Caliburn devices are often recommended to both beginners and experienced vapers. But with so many models released under the Caliburn name—such as the original Caliburn, Caliburn G, G2, A2, AK2, X, and the newer Caliburn Tenet—many users are left wondering: Which Uwell Caliburn is worth it in 2025?
This comprehensive review dives deep into each model, comparing their performance, battery life, coil compatibility, and unique features. Whether you’re just starting or looking to upgrade, this guide helps you make a confident choice in the Uwell Caliburn series.
Why the Uwell Caliburn Series Is So Popular
Before we break down individual models, it’s important to understand why this series is so well-regarded. First, Uwell has consistently focused on improving flavor delivery using their proprietary Pro-FOCS technology. This ensures that every puff is smooth, rich, and consistent. Second, the design language across the Caliburn series is minimal, elegant, and pocket-friendly—perfect for everyday use. Finally, these devices are easy to use, require minimal maintenance, and have a long coil life, making them ideal for busy vapers.
Comparing Top Models in the Uwell Caliburn Series
Caliburn G vs Caliburn G2
The Caliburn G was the first to introduce replaceable coils to the series. It brought more customization than the original and offered tighter airflow control with a stronger battery. Users loved the enhanced flavor and the solid 690mAh battery.
Then came the Caliburn G2, which added more refinement to the design. It introduced a haptic feedback system, a wheel-based airflow control, and an even better coil system. The 750mAh battery offered slightly better performance. If you’re looking for a slightly more refined vaping experience with tactile feedback and improved ergonomics, the G2 is a smart pick over the original G.
Caliburn A2 vs AK2
These two models are more compact and cater to users who prefer an auto-draw-only experience. The Caliburn A2 has a slim, pen-style body with a 520mAh battery and uses meshed 0.9-ohm pods. Its strong suit is excellent flavor and ease of use—ideal for beginners.
The Caliburn AK2, on the other hand, is the square version of the A2, designed for portability. It uses the same pods but fits better in the palm and pocket. The experience is nearly identical in terms of performance. So, it comes down to form factor—do you prefer the sleek stick-style (A2) or compact box-style (AK2)?
Caliburn X
The Caliburn X is for users who want more control. It features an OLED screen, a fire button, and adjustable wattage up to 20W. It uses Caliburn G-series coils and comes with a 850mAh battery. The screen is a welcome upgrade that displays wattage, battery, and coil resistance.
This model is perfect for intermediate vapers who want customization but aren’t ready to jump to box mods. The Caliburn X bridges the gap between simple pods and advanced vaping devices while retaining flavor and portability.
Caliburn Tenet and Tenet Koko
These two are recent additions to the series. The Caliburn Tenet has a steampunk-style rugged metal design, 750mAh battery, and compatibility with G and G2 coils. The Tenet Koko, being the boxy counterpart, also uses the same coil system but is geared toward those who prefer the shorter body shape.
What makes these stand out is the military aesthetic and durability. If you’re looking for a Caliburn that doesn’t just perform but looks unique and can handle a bit of abuse, the Tenet series is for you.
Coil System and Flavor Comparison
One of the most praised aspects of the Uwell Caliburn series is the flavor. All devices utilize Uwell’s Pro-FOCS technology, which enhances flavor by properly controlling temperature and ensuring the e-liquid is evenly heated.
The G and G2 coils offer the richest flavor and longest coil life. Users consistently report a warm, full-bodied vape with excellent throat hit. The A2 and AK2 pods are also flavorful but offer slightly less customization due to their fixed coils.
If you’re a flavor chaser, the G2 coils (especially the 1.2Ω mesh) are among the best in any pod system today.
Battery Life and Charging Speed
Battery capacity in the Caliburn series varies. Here’s a rough estimate:
- Caliburn A2/AK2: 520mAh – lasts about half a day with moderate use
- Caliburn G/G2: 690–750mAh – easily lasts a full day for light to medium users
- Caliburn X: 850mAh – great for heavy users
- Caliburn Tenet Series: 750mAh – solid performance with fast recharging
All devices charge via USB Type-C, ensuring fast charging (within 30–45 minutes). The LED indicators and screen (in the X) help you monitor battery status easily.
Which Uwell Caliburn Is Right for You?
Here’s how to decide:
- New vaper or someone switching from cigarettes? Choose the Caliburn A2 or AK2. They are simple, auto-draw, and flavor-rich.
- Want a balance of performance and customization? Go for Caliburn G2.

Any Downsides?
No product is perfect. While the Uwell Caliburn series performs excellently, here are a few points to consider:

When it comes to the Uwell Caliburn series, the answer to which one is worth it depends on your vaping style. For beginners, the A2 and AK2 are unbeatable in simplicity.
