Uwell Caliburn G2 vs G3 – What Changed?
If you’re wondering which is better between the Caliburn G2 vs G3, you’re not alone. Uwell’s Caliburn series has long been a favorite among vapers, known for their sleek design, portability, and consistent flavor delivery. But as with any new release, the G3 introduces several upgrades—and a few trade-offs—that may impact your choice.
Whether you’re thinking of upgrading from the G2 or buying your first Caliburn, this deep-dive comparison will break down the real differences. From design and performance to coil compatibility and user experience, we’ve got it all covered. Let’s explore what truly sets the Caliburn G2 vs G3 apart.
Design and Build Quality
The first noticeable difference between the Caliburn G2 and G3 is in their appearance and ergonomics. Both devices retain the slim, pocket-friendly style Caliburn is known for, but Uwell gave the G3 a more modern edge.
Sleeker Body in the G3
The G3 features a cleaner, more refined chassis. It feels slightly slimmer and lighter in the hand compared to the G2. The fire button on the G3 is flush with the body, giving it a minimalist look and reducing accidental presses—a common complaint with the G2.
G2’s Curved Mouthpiece Still Wins Some
However, many users still prefer the G2’s curved mouthpiece for comfort during long vaping sessions. The G3 shifted to a flatter, more squared-off drip tip, which some vapers find less ergonomic.
Coil and Pod System
Coils are where the vaping experience can drastically differ, and the Caliburn G2 vs G3 comparison shines here.
G2 Offers Replaceable Coils
The Caliburn G2 uses replaceable coils, allowing users to switch between 1.2Ω and 0.8Ω mesh coils. This flexibility is perfect for those who want to fine-tune their vaping style between MTL (mouth-to-lung) and RDL (restricted direct lung). It also saves money in the long run, as you only need to replace the coil rather than the entire pod.
G3 Moves to Integrated Coils
The G3 switches to disposable pods with built-in coils. While this offers convenience—just swap the pod when flavor drops—it removes the ability to change only the coil. This means slightly higher recurring costs but a more plug-and-play experience ideal for beginners.
Coil Performance
Both devices produce clean, accurate flavor, but the G3’s new 0.6Ω pod delivers a warmer, denser vapor that feels closer to a sub-ohm vape. If you’re after stronger hits and bigger clouds in a small device, the G3 stands out.
Battery and Charging
Battery life can be a deciding factor for many users. In the Caliburn G2 vs G3 debate, both devices offer decent power, but G3 brings a few key enhancements.
Bigger Battery in the G3
The G2 has a 750mAh battery, while the G3 upgrades that to 900mAh. It may seem like a small jump, but it adds noticeable extra usage time—especially important for moderate to heavy vapers.
Faster Charging
Both devices use USB-C charging, but the G3 supports faster charging. You can top up from zero to full in under 30 minutes, a real game-changer when you’re in a rush.
Performance and Vaping Experience
Flavor quality, throat hit, and vapor production all shape your experience. Here’s how things differ in the Caliburn G2 vs G3 face-off.
Smoother Draw in G3
The G3 offers a tighter airflow overall, especially with the 0.9Ω pod, making it more suitable for a pure MTL experience. The draw feels more natural and cigarette-like, ideal for those transitioning from smoking.
Adjustable Power
One of the biggest upgrades in the G3 is the adjustable wattage. You can choose between three levels of output, depending on the pod resistance. The G2, on the other hand, relies entirely on auto-adjustment, which removes customization but simplifies use.
Button Lock and Draw Activation
The G3 gives you the option to lock the fire button entirely and use only draw activation. This reduces pocket-firing and improves safety. The G2 offers both modes but lacks the G3’s refined control.
Display and Controls
One area where the Caliburn G2 vs G3 comparison leans heavily toward the newer model is user interface.
OLED Screen in the G3
The G3 includes a small OLED screen showing battery life, wattage, and coil resistance. It’s not just about looks—it adds functionality and lets you monitor performance more precisely.
G2’s Simplicity Appeals to Minimalists
While the G2 lacks a display, its simplicity makes it appealing to users who just want to vape without any adjustments. For some, less is more.
E-Liquid Capacity and Refill Method
Both models are easy to refill, but there’s a small difference worth noting.
2ml Capacity
Both G2 and G3 pods hold 2ml of e-liquid, which is standard for compact pod systems and compliant with TPD regulations in many regions.
Top Fill System
Both feature a top-fill mechanism under the mouthpiece. However, the G2’s red fill valve is slightly easier to access and reseal, making it more leak-resistant for daily carry.
Price and Value
Price-wise, both devices sit in a similar range, with the G3 typically costing slightly more due to its added features.
Is the G3 Worth the Upgrade?
If you value adjustable wattage, a display, and integrated coils for convenience, the G3 is absolutely worth the extra investment. But if you’re on a budget and prefer replaceable coils for long-term savings, the G2 still holds its ground as a solid, flavor-packed device.
Compatibility and Accessories
G2 Offers Wider Compatibility
The G2 is compatible with all Caliburn G-series coils and pods, including older models. This offers flexibility if you already own Uwell products. The G3, being a newer system, currently has fewer pod options.
G3 Will Grow with Time
That said, as Uwell expands the G3 lineup, more pod options and accessories are likely to become available, possibly giving it more long-term flexibility.
Caliburn G2 vs G3
Choosing between Caliburn G2 vs G3 depends on your priorities. The G2 is a tried-and-true favorite with replaceable coils, a comfortable draw, and minimalistic controls. It’s ideal for budget-conscious vapers or those who like more control over coils.
The G3, however, brings clear upgrades in design, battery life, performance, and ease of use. Its adjustable wattage, OLED screen, and smoother MTL experience make it perfect for vapers who want more from their pod system without sacrificing portability.
If you’re upgrading from the G2 and want the latest tech with better battery and vapor production, the G3 is a strong step forward. But if you prefer simplicity and coil-swapping flexibility, the G2 remains a smart choice.
