This pod kit blends innovation with user-friendly design. Now, let’s dive into its standout aspects.
Design and Build Quality
The Caliburn G4 Pro boasts a premium look. Its aluminum-alloy chassis feels lightweight yet durable. Weighing just 55g, it’s highly portable. The device fits comfortably in your pocket or hand. Its sleek, curved edges enhance grip. Subtle etched patterns add elegance without being flashy.
The 2.51-inch touchscreen is a first for Uwell. It’s responsive and shatter-resistant. You can navigate settings with a single tap. The screen offers six UI themes, three available out of the box. Unlock more at 5,000, 10,000, and 20,000 puffs. This gamified feature adds fun to vaping. You can even rename the device for a personal touch.
The droplet-shaped e-liquid window is practical. It lets you check juice levels easily. The side-fill system, paired with U² Anti-Leak Technology, prevents messes. The magnetic pods snap securely into place. Overall, the design balances style and functionality perfectly.
However, the touchscreen may feel gimmicky to some. It can also drain the battery slightly faster. Still, the premium build and intuitive controls make it a joy to use.
Battery Life and Charging
Battery life is a critical factor for vapers. The Caliburn G4 Pro delivers here. Its 1800mAh battery is a significant upgrade over the G4’s 1300mAh. For moderate vapers, it lasts a full day. Heavy users may need a midday charge. The USB Type-C port ensures fast charging. A full charge takes about 30–35 minutes.
The touchscreen displays clear battery indicators. You’ll always know your charge level. Passthrough vaping lets you use the device while charging. This feature minimizes downtime. However, some users report the battery percentage display isn’t always accurate. This minor quirk doesn’t overshadow the battery’s reliability.
Compared to competitors like the Vaporesso Xros 4, the G4 Pro’s battery stands out. Its capacity and fast charging make it ideal for on-the-go vaping. At Vegas Vapor, we appreciate devices that keep up with busy lifestyles. The G4 Pro does just that.
Flavor Performance
Flavor is where the Caliburn G4 Pro shines. Uwell’s PRO-FOCS 4.0 technology boosts flavor by 35%. It delivers rich, vibrant tastes with every puff. The device supports 0.4–0.9ohm pods. These cater to both mouth-to-lung (MTL) and restricted direct-lung (RDL) vaping.
Three vaping modes enhance customization:
- Storm Mode: Delivers instant, intense throat hits. Perfect for bold flavors.
- Waves Mode: Offers smooth, steady puffs. Ideal for a relaxed vape.
- Custom Mode: Lets you adjust power output for a tailored experience.
The adjustable airflow switch fine-tunes your draw. Switch between tight MTL or airy RDL with ease. The 0.4ohm pod produces dense clouds. The 0.9ohm pod excels for nic salts. Both pods deliver consistent flavor without spitback.
The GPP pods are compatible with G3 series devices. This cross-compatibility saves money for upgraders. The pods’ 35% longer lifespan reduces replacements. At Vegas Vapor, we tested various e-liquids. From fruity to dessert flavors, the G4 Pro performed flawlessly.
Ease of Use
The Caliburn G4 Pro is beginner-friendly. Its draw-activated system requires no setup. Just inhale to vape. The touchscreen simplifies adjustments. Swipe down to access the settings hub. Change modes, themes, or wattage with ease. The multi-function button handles power and menu navigation.
Refilling is hassle-free. The side-fill system doesn’t require pod removal. The U² Anti-Leak Technology keeps things clean. The 3mL pod capacity reduces refill frequency. Magnetic pods ensure a secure fit. Even new vapers will find the G4 Pro intuitive.
For experienced vapers, the customization options are a plus. Adjust wattage, airflow, or modes to suit your style. However, Custom Mode may overwhelm beginners. It requires tweaking power at different puff stages. Most users will stick to Storm or Waves Mode for simplicity.

How It Compares
The Caliburn G4 Pro outshines its predecessor, the G4. The G4 has a smaller 1300mAh battery and a 0.85-inch screen. It lacks the touchscreen and Custom Mode. The G4 Pro also surpasses the G3 Pro, which has a full-screen display but no touch control. Compared to the Vaporesso Xros 4, the G4 Pro offers a larger battery and more customization. However, the Xros 4 is slightly more compact.
At Vegas Vapor, we believe the G4 Pro strikes a perfect balance. It’s advanced yet accessible. Its flavor and battery life rival top pod systems in 2025.
