2. Unique Features of the Uwell Caliburn G4
The Uwell Caliburn G4 doesn't just stop at numerical improvements; it introduces a range of features that tangibly enhance the user experience.
- Advanced heating system with two power modes: The device offers two new power modes: 'Storm' mode, which provides an instant, powerful, and intense draw, and 'Waves' mode, which offers a smoother, more gradual power experience, giving users unprecedented customization options in a pod device.
- Ease of use and maintenance: Thanks to the new side-filling system, it's no longer necessary to completely remove the pod to refill it. The device also operates with a single multi-function button to control everything, from turning it on to changing settings, making it simple even for beginners.
- Elegant design and multiple options: The device comes with a durable and lightweight aluminum alloy body, with 8 attractive color options. The new color screen comes with different themes and animations, adding a personal and fun touch to the device.

3. The Pursuit of Excellence and Leak Resistance
In the Caliburn G4, the focus was on a clean and excellent vaping experience. Thanks to Uwell's proprietary U² technology, consisting of 'Ultrasonic Welding' and a 'U-shaped Channel Design' in the pod base, the performance of the coils (CALIBURN GPP cartridges) has been significantly improved to resist leaking. The goal is to ensure every drop of e-liquid stays where it belongs. This technology guarantees that the coils are effectively leak-resistant, providing a great, clean vaping experience without any waste.
Technical Features:
- Ultrasonic Welding: Enhances performance to resist leaking.
- U-shaped Channel Design: Improves airflow and makes the vaping experience smoother.
Multi-function Control Button
The Caliburn G4 comes with a single multi-function control button, making the device easy and straightforward to use. This button controls everything, from turning on the screen to adjusting the wattage (power).
How to use it:
- Single press (x1): To turn on the screen.
- Two presses (x2): To lock or unlock the fire button.
- Three presses (x3): To adjust the wattage.
- Four presses (x4): To enter the Menu.
- Five presses (x5): To turn the device ON/OFF.
4. User Experience: Real-World Performance of the Caliburn G4
Beyond the numbers and specifications, how does the Uwell Caliburn G4 actually perform?
Vapor and Flavor Quality:
This is where the device truly shines. Thanks to the Pro-FOCS 4.0 technology, the Caliburn G4 delivers a rich and clear flavor that is among the best in its class. Whether you are using the 0.6 ohm pod for an RDL (Restricted Direct Lung) draw or the 0.9 ohm pod for an MTL (Mouth-to-Lung) draw, the performance is consistent and the flavor is excellent.
Durability and Build Quality:
The metal body gives the device a solid and durable feel. However, some reviewers have pointed out minor design flaws, such as the screen attracting fingerprints easily, and the rounded base of the device preventing it from standing upright, which could increase the likelihood of leaking during storage.
Battery and Charging Speed:
On paper, the 1300 mAh battery seems like a significant upgrade. However, tests have shown that its actual life is similar to devices with smaller batteries, lasting for the equivalent of vaping 4-5 ml of e-liquid. But the real advantage is the charging speed, as the device can be fully charged in just about 30 to 45 minutes.
5. Comparing the Caliburn G4 with Competing Devices
To put the Uwell Caliburn G4 in its proper context, it must be compared to its main competitors.
Caliburn G4 vs. Caliburn G3:
- The G4 is a clear upgrade with a 35% larger battery (1300 vs. 900 mAh), higher maximum power (35 vs. 25W), a color screen, and new power modes.
- In contrast, the G3 retains a slightly larger pod capacity (2.5 ml vs. 2 ml in the standard version of the G4).
Caliburn G4 vs. Voopoo Argus G3:
- Both offer excellent flavor, but the Argus G3 excels with a larger battery (1500 mAh) and slightly faster charging.
- On the other hand, the Caliburn G4 features a more elegant design and a better-animated screen.
- The choice between them remains a matter of personal preference between battery life and design.
6. Tips for Optimal Use of the Uwell Caliburn G4
To get the best possible experience from your device, follow these tips:
- Proper Filling: When filling the pod, tilt it slightly to avoid e-liquid entering the central air tube. Do not fill the pod completely; leave a small air pocket to prevent leaking.
- Regular Cleaning: Clean the metal contact points between the pod and the device regularly with a dry cotton swab to remove any condensation or leaked liquid and ensure a good connection.
- Suitable E-liquids: For the best flavor and longer coil life, use 50/50 VG/PG liquids, especially with higher resistance pods (like the 0.9 ohm) designed for MTL vaping.
- Extending Battery Life: Try to charge the device before the battery level drops below 10%, and avoid leaving it on the charger for long periods after it's fully charged.
