When a brand like Uwell drops a new device in the Caliburn lineup, expectations are already sky-high. This is a series that has built its reputation on reliability, flavor, and simplicity. So when the Caliburn G4 Pro 35W Pod Kit was announced, the question wasn’t just whether it would be good—it was whether it could actually raise the bar again.
The answer is pretty clear: it does, and in a way that feels genuinely modern.
What do we mean by that? Well, let's explain...
The Uwell Caliburn G4 Pro Kit: An Overview
The first thing that stands out about the Caliburn G4 Pro is the touchscreen. Not a small display tucked away on the side, but a full 2.51-inch responsive screen that dominates the front of the device. This is something that immediately separates it from most pod systems on the market.
Vaping devices have been slowly adding more tech over the years, but this feels like a real leap forward.
The features
The first thing you may see is the screen... and it isn’t just for show. It’s functional, customizable, and surprisingly engaging. Users can switch between multiple UI themes, adjust brightness, toggle between day and night modes, and even choose from different language settings.
There’s even a device naming feature, which adds a subtle but fun layer of personalization. It turns what used to be a simple tool into something that feels more like a personal gadget.
What’s interesting is how this touchscreen changes the way people interact with their device. Instead of clicking buttons or memorizing combinations, everything becomes intuitive. One tap, one swipe, and the device responds instantly. For some, especially those used to traditional pod systems, there might be a small learning curve. But once it clicks, it’s hard to go back.
Performance
Beyond the interface, the performance of the G4 Pro is where it really earns its place. Powered by an 1800mAh battery, this device is built to last through the day and then some. Battery anxiety is one of the most common frustrations in vaping, and Uwell clearly made it a priority to address that.
Combined with 2A fast charging, the downtime is minimal, which makes a big difference in everyday use.
The device supports up to 35W of output, which puts it in a sweet spot for both MTL and RDL vaping styles. That flexibility is important because not every user wants the same experience.
Some prefer a tighter, cigarette-like draw, while others want something a bit more open with increased vapor production. The G4 Pro handles both without feeling like it’s compromising in either direction.
The Uwell Caliburn G4 Pro Pod Kit was built for explosive flavors
A big part of that performance comes from Uwell’s Pro-FOCS 4.0 technology. This is where the flavor really shines. The system is designed to enhance consistency and depth, so every puff feels as close to the first as possible.
Paired with the GPP pod compatibility and coil options ranging from 0.4Ω to 0.9Ω, the result is a smooth, flavorful experience that feels refined rather than overpowering.
Airflow control also plays a role here. The adjustable slider allows users to fine-tune their draw, moving from a tight MTL inhale to a looser RDL style. It might feel slightly firm at first, but that resistance actually helps maintain precision. Once it’s set, it stays exactly where it needs to be.
The build quality is another area where the G4 Pro stands out. Constructed from aluminum alloy, it has a solid, premium feel without becoming too heavy. The finish is sleek, modern, and available in multiple color options, giving users the chance to pick something that matches their style. It’s compact enough to fit comfortably in a pocket, but it doesn’t feel fragile or cheap.
A mess-free 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 it can be. This system significantly reduces that risk, making the overall experience cleaner and more reliable.
The side-fill design also makes refilling straightforward, which is especially important for users who don’t want to deal with complicated setups.
Of course, no device is perfect.
Pros and Cons of the Uwell Caliburn G4 Pro Pod Kit
The 3mL capacity is decent, but some use rs might wish it were slightly larger, especially those who vape frequently throughout the day. And while the touchscreen is a major highlight, it may not appeal to everyone right away. Some users prefer the simplicity of button-based systems and might need a little time to adjust.
But these are relatively minor trade-offs when compared to what the device offers overall.
What makes the Caliburn G4 Pro so compelling is how it blends innovation with usability. It doesn’t just add features for the sake of it—it integrates them in a way that actually improves the experience.
The touchscreen isn’t gimmicky, the performance isn’t overhyped, and the design isn’t just about looks. Everything works together to create a device that feels cohesive and thoughtfully designed.
For beginners, it offers an easy entry point with room to grow. For experienced users, it provides enough customization and performance to stay interesting. That balance is difficult to achieve, but Uwell manages to pull it off here.
