The Caliburn X isn’t just a Caliburn with a screen. It blends the A series design with the G series’ replaceable coils, creating a powerful hybrid. With an 850mAh battery, adjustable airflow, and multiple coil options, it’s built for versatility.
UWELL Caliburn X is the latest in the popular Caliburn series, introducing a new sub-line. Unlike previous models, it features an OLED screen, full wattage adjustability, an 850mAh battery, and 3mL pods. While its design is larger, it remains compatible with Caliburn G coils, offering three coil options.

Build quality and design
Caliburn X breaks the traditional mold with a thicker, yet still compact and lightweight design (107.4mm x 27.5mm x 15.6mm). It features a larger mouthpiece, though I prefer the A2 or original Caliburn’s. The standout addition is the black-and-white screen, displaying key vape stats like charge, wattage, and puffs—likely setting a trend for future models.
With a matte finish and a sleek reflective panel around the button and screen, the build quality is solid, though the airflow slider feels a bit loose at times.
Getting started
The X may be the most advanced Caliburn to date, but it’s not a very complicated device to set up and use:
- Drip 4-5 drops of e-juice into the coil.
- Insert the coil into the pod, aligning the cutout.
- Attach the pod to the battery.
- Remove the mouthpiece by pushing the flat side.
- Fill the pod using the red-marked hole.
- Wait 5 minutes for saturation.
- Adjust airflow with the slider.
- Press the button or inhale to vape.
And here’s a rundown of button operations:
Press fire five times to turn the device on/off.
Press fire three times to adjust the wattage (wattage will start blinking).
Press fire three times to adjust the wattage (wattage will start blinking).
Press fire two times to lock/unlock the fire button (auto-draw still works).
My only gripe is the lack of auto wattage adjustment when inserting the pod, a common feature in many devices. Having to check the wattage range for each coil can be annoying. Otherwise, it’s a hassle-free device that experienced vapers will find easy to use.
Performance
Since the Caliburn X uses G series coils, its performance is similar to the Caliburn G and G2, with the added benefit of full wattage adjustability for fine-tuning. The included 1.2Ω (9-13W) coil is ideal for mid-strength nic salts, while the 0.8Ω (13-18W) coil works well for regular nic and lower-strength salts, even allowing for some RDL vaping with open airflow. Coil life averages 20-25mL, and they handle up to 70VG with ease.
While some users report leakage, my testing showed minimal issues—only occasional drops, which is normal for pod vapes. The auto-draw sensor is highly responsive, making the button almost unnecessary. I did encounter an atomizer short with one 0.8Ω coil, but reinserting the pod resolved it.
Battery life and charging
The Caliburn X features an 850mAh battery with Type-C charging. While I expected closer to 1000mAh given its size, it still offers solid battery life for a pod system. Using the 1.2Ω coil at 12W, I vaped over 6mL before needing a recharge, though performance dipped near the end.
A full charge takes around 52 minutes, with faster charging up to 80% before slowing down. It also supports passthrough charging, so you can vape while plugged in.

CONCLUSION
Caliburn X is a well-built pod system with great coils, a screen, full airflow and power adjustability, and a long-lasting, fast-charging battery.
While it may not be the best choice for first-time vapers—simpler options like the Caliburn A2 or VAPORESSO LUXE QS offer similar performance—it’s a great pick for those looking to fine-tune their vaping experience with extra features.
