When a brand like Uwell releases a new device in the Caliburn lineup, expectations are already high. This is a series known for reliability, smooth flavor delivery, and simplicity that just works. So when the Caliburn G4 Pro 35W Pod Kit entered the conversation, the real question wasn’t whether it would be good—it was whether it could actually push things forward.
It turns out, it does. And not in a flashy, over-the-top way, but in a way that feels genuinely modern and practical.
A First Look That Feels Different
Right away, the most noticeable feature is the touchscreen. This isn’t a small display tucked off to the side—it’s a full 2.51-inch screen that takes center stage on the front of the device.
That alone separates it from most pod systems currently on the market. While vaping tech has gradually evolved over time, this feels like a real leap instead of a small step.
But the screen isn’t just there to look impressive. It’s functional in a way that actually changes how the device is used day to day.
A Touchscreen That Actually Adds Value
The interface is where things start to feel more like a smart device than a traditional vape. Users can switch between different UI themes, adjust brightness, toggle between day and night modes, and even change language settings.
There’s even a naming feature, which adds a small but surprisingly enjoyable level of personalization. It turns the device from something purely functional into something that feels a bit more personal.
What stands out most is how intuitive everything becomes. Instead of clicking buttons or remembering combinations, it’s all taps and swipes. For anyone used to older pod systems, there might be a short adjustment period—but once it clicks, it’s hard to go back to anything else.
Performance That Matches the Tech
All the features in the world don’t matter if the performance doesn’t hold up. Fortunately, the G4 Pro delivers where it counts.
Powered by an 1800mAh battery, it’s built to last comfortably through a full day of use and often beyond. That alone solves one of the biggest frustrations for many users—constantly worrying about battery life.
With 2A fast charging, downtime is minimal. When it does need a charge, it gets back up and running quickly, which makes a noticeable difference in everyday use.
The device also supports up to 35W of output, putting it in a sweet spot for both MTL (mouth-to-lung) and RDL (restricted direct lung) vaping styles. Whether someone prefers a tighter, cigarette-like draw or something a bit more open with increased vapor, the device adapts without feeling like it’s compromising.

Flavor That Stays Consistent
A big part of what makes the Caliburn line so popular is flavor, and the G4 Pro continues that tradition.
This is where Pro-FOCS 4.0 technology comes into play. It’s designed to maintain consistency and depth, so each puff feels just as satisfying as the last. Instead of flavor dropping off over time, it stays stable and clean.
With GPP pod compatibility and coil options ranging from 0.4Ω to 0.9Ω, users have flexibility in how they fine-tune their experience. The result is a vape that feels smooth, controlled, and refined rather than overly aggressive.
Control, Build, and Everyday Use
Airflow control adds another layer of customization. The adjustable slider allows users to dial in their preferred draw, whether that means tight and focused or loose and airy. It may feel slightly firm at first, but that resistance actually helps keep it in place once it’s set.
Build quality is another area where the G4 Pro stands out. The aluminum alloy construction gives it a premium feel without adding unnecessary weight. It’s sturdy, sleek, and compact enough to carry comfortably without feeling fragile.
Everything about the design feels intentional. It doesn’t try too hard—it just works.
A Cleaner, More Reliable Experience
One of the more practical upgrades is the inclusion of U² anti-leak technology. Anyone who has dealt with leaking pods knows how frustrating that can be. This feature significantly reduces that issue, making the overall experience cleaner and more reliable.
The side-fill design also keeps things simple. Refilling doesn’t feel like a chore, which is important for a device meant to be used daily.
A Few Small Trade-Offs
No device is perfect, and the G4 Pro has a couple of minor drawbacks.
The 3mL capacity is solid, but heavier users might wish it held a bit more to reduce how often they need to refill. And while the touchscreen is a standout feature, it may not immediately appeal to everyone. Some users prefer the simplicity of buttons and may need a little time to adjust.
That said, these are relatively small trade-offs when compared to what the device offers overall.

Final Thoughts: A Smart Evolution
What makes the Caliburn G4 Pro so compelling is how well it balances innovation with usability. It doesn’t add features just for the sake of it—everything serves a purpose and improves the experience in a meaningful way.
The touchscreen feels useful rather than gimmicky, the performance is consistent, and the design is both modern and practical. It’s a device that works just as well for beginners as it does for more experienced users.
The Caliburn series has always been about reliability and simplicity. With the G4 Pro, that formula evolves into something more advanced without losing what made it successful in the first place.
And in a market that’s constantly pushing forward, that kind of thoughtful evolution is exactly what keeps a brand ahead of the curve.
