Known for setting the standard for flavor and portability, Uwell has once again raised the bar with the Caliburn G4. At Vegas Vapor, we’re thrilled to dive into this comprehensive review, exploring why this pod vape is a top contender for both new and seasoned vapers in 2025. With a robust 1300mAh battery, cutting-edge PRO-FOCS 4.0 flavor technology, and a sleek, compact design, the Caliburn G4 promises an exceptional vaping experience. Let’s break down its features, performance, and why it’s a must-have for your vaping collection.
Introduction to the Uwell Caliburn G4
The Uwell Caliburn series has long been a favorite among vapers, starting with the original Caliburn, which revolutionized pod systems with its simplicity and flavor quality. The Caliburn G4 builds on this legacy, combining modern technology with user-friendly design. Whether you’re chasing bold flavors, long-lasting battery life, or a device that slips easily into your pocket, the Caliburn G4 delivers. Available at Vegas Vapor, this pod vape kit is designed for both mouth-to-lung (MTL) and restricted direct-to-lung (RDTL) vaping styles, making it versatile for a wide range of preferences.
In this 1500+ word review, we’ll cover the design, features, performance, and user experience of the Caliburn G4, comparing it to its predecessor, the Caliburn G3, and its sibling, the Caliburn G4 Mini. We’ll also highlight why Vegas Vapor is your go-to destination for this innovative vape device. Let’s get started!
Design and Build Quality: Sleek and Sturdy
The Uwell Caliburn G4 retains the series’ signature minimalist aesthetic while introducing a modern makeover. Crafted from durable aluminum alloy, the G4 weighs just 48g, making it one of the lightest pod vapes in its class. Its compact dimensions ensure it fits comfortably in your pocket or bag, perfect for vapers on the go. The rounded corners and ridged design provide excellent grip, preventing slips even during extended use.
Available in 12 vibrant colors, including eye-catching options like Peafowl Emerald and Phoenix Purple, the Caliburn G4 exudes style without sacrificing sophistication. The front features a 0.85-inch HD color screen, a significant upgrade from previous models, displaying wattage, battery life, and vaping mode with customizable themes. The screen is bright and intuitive, though it can attract fingerprints, a minor drawback noted by some users.
The device also includes a clear-view e-liquid window, allowing you to monitor juice levels at a glance. However, some vapers have pointed out that the window is small and can be hard to see in low light, especially with the black mouthpiece obstructing visibility. Despite this, the top-fill system is user-friendly, and the pod’s ultrasonic welding and U-shaped channel design significantly reduce leaks, ensuring a mess-free experience.
Key Design Features:
- Material: Lightweight aluminum alloy for durability and portability.
- Weight: Only 48g, ideal for everyday carry.
- Display: 0.85-inch HD color screen with customizable themes.
- Colors: 12 vibrant options, including Glacier Blue and Slate Grey.
- E-Liquid Window: Clear-view design, though visibility could be improved.
Advanced Features: Power and Customization
The Uwell Caliburn G4 is packed with features that set it apart from other pod vape kits. Its 1300mAh battery is a major upgrade from the 690mAh battery in the Caliburn G and even surpasses the 750mAh battery in the Caliburn G2. This larger battery capacity ensures all-day vaping for most users, with quick Type-C charging to minimize downtime.
One of the standout features is the introduction of two vaping modes: Storm Mode and Waves Mode. Storm Mode delivers an intense, rapid burst of vapor, perfect for quick nicotine hits, while Waves Mode offers a smoother, more consistent draw for savoring flavors. Switching between modes is seamless via the multifunctional button, which also adjusts settings and locks the device.
The Caliburn G4 supports a maximum output of 35W, a significant leap from the 18W of earlier models, catering to both MTL and RDTL vapers. The adjustable airflow slider allows precise control over draw resistance, from tight MTL to airier RDTL, making it highly customizable. The device is compatible with both G3 and G4 pods, including the new GPP (G Pod Platform) cartridges, which feature a 35% longer lifespan and enhanced ergonomics.
Notable Features:
- Battery: 1300mAh for extended vaping sessions.
- Power Modes: Storm Mode for intense hits, Waves Mode for smooth draws.
- Wattage: Up to 35W, suitable for MTL and RDTL vaping.
- Airflow: Adjustable slider for personalized draw resistance.
- Pod Compatibility: Works with G3 and G4 GPP pods for versatility.
- Performance: Bold Flavors with PRO-FOCS 4.0
When it comes to performance, the Uwell Caliburn G4 shines, thanks to Uwell’s renowned PRO-FOCS 4.0 flavor technology. This advanced system optimizes coil performance, delivering rich, consistent flavors with every puff. Whether you’re using nicotine salts or freebase e-liquids, the G4 ensures the true essence of your juice is preserved, from fruity blends to complex tobacco flavors.
The kit includes two mesh pods: a 0.6Ω pod for RDTL vaping and a 0.9Ω pod for MTL draws. The 0.6Ω pod is ideal for lower-strength nic salts or freebase liquids (6–12mg), offering a slightly airier draw and robust vapor production. The 0.9Ω pod, on the other hand, provides a tight MTL experience, perfect for higher nicotine strengths. Both pods benefit from Uwell’s U² technology, which ensures even coil heating to prevent hotspots and extend coil life.
In testing, the Caliburn G4 delivered exceptional flavor clarity. Whether vaping a dessert e-liquid or a menthol blend, each note was distinct and vibrant, with no burnt or muted flavors even after a week of use. The vapor production, while not cloud-chasing, is impressive for a pod system, striking a balance between flavor and vapor. However, some users have reported that the battery life, while substantial, doesn’t always match expectations for heavy vapers, and the screen’s battery percentage display can occasionally be inaccurate.
Performance Highlights:
- Flavor Quality: PRO-FOCS 4.0 ensures rich, consistent flavors.
- Coils: 0.6Ω for RDTL, 0.9Ω for MTL, with long-lasting performance.
- Vapor Production: Satisfying for a compact pod system.
- Battery Life: 1300mAh supports all-day vaping for most users.
User Experience: Simplicity Meets Innovation
The Uwell Caliburn G4 is designed with user convenience in mind. Its draw-activated mechanism eliminates the need for complex menus—just puff and vape. The multifunctional button adds flexibility, allowing you to adjust settings or fire the device manually for a warmer vape. The top-fill pod system is straightforward, though the small e-liquid window can make refilling tricky in dim lighting.
The G4’s compatibility with G3 pods is a major plus for existing Caliburn users, as it reduces the need to invest in a new ecosystem. The GPP pods are ergonomically designed for comfort, and the U² leak-resistant technology ensures a clean vaping experience. The adjustable airflow slider allows vapers to fine-tune their draw, catering to both beginners and enthusiasts.
At Vegas Vapor, we appreciate the G4’s balance of simplicity and advanced features. The customizable UI and vibrant screen make it feel premium, while the compact design ensures it’s practical for daily use. However, the fingerprint-prone screen and less-than-ideal e-liquid window are minor drawbacks that Uwell could address in future iterations.
User Experience Benefits:
- Ease of Use: Draw-activated with an intuitive multifunctional button.
- Pod System: Top-fill design with leak-resistant GPP pods.
- Customization: Adjustable airflow and dual vaping modes.
- Portability: Lightweight and pocket-friendly for on-the-go vaping.
Caliburn G4 vs. G4 Mini vs. G3: Which Is Right for You?
The Uwell Caliburn G4 stands out in the Caliburn lineup, but how does it compare to the Caliburn G4 Mini and Caliburn G3? Here’s a quick breakdown:
- Caliburn G4: Features a 1300mAh battery, 0.85-inch HD screen, and dual vaping modes (Storm and Waves). It’s ideal for vapers who want advanced features and customization.
- Caliburn G4 Mini: A stripped-down version with an 1100mAh battery, no screen, and simpler operation. It’s perfect for beginners or those prioritizing portability.
- Caliburn G3: Offers a 900mAh battery and lacks the G4’s dual modes and larger screen. It’s still a solid choice but feels less advanced.
If you value cutting-edge technology and don’t mind a slightly larger device, the G4 is the way to go. For a more budget-friendly, compact option, the G4 Mini is a great alternative. Existing G3 users can upgrade to the G4 without losing pod compatibility, making it a cost-effective choice.
