Vaping has always been about finding the perfect balance between convenience, performance, and satisfaction. The Uwell Caliburn G4 Pro Pod Kit represents that balance beautifully. It’s not just another upgrade—it’s a complete rethinking of what a pod device can do. With a large touchscreen, multiple vaping modes, leak-proof design, and stunning aesthetics, the Caliburn G4 Pro sets a new standard in modern vaping.
This detailed review explores everything about the G4 Pro: its design, performance, display features, pod compatibility, battery, available colors, and overall experience. If you’re considering upgrading your current pod system, this comprehensive breakdown will help you understand why the Uwell Caliburn G4 Pro is one of the most exciting pod kits available today.
A New Era of Design
The first thing you notice about the Uwell Caliburn G4 Pro is its refined and futuristic design. The device is slim, lightweight, and perfectly contoured for comfort. With dimensions of around 120.7 mm in height, 30 mm in width, and 18.5 mm in depth, it fits easily in your hand or pocket without feeling bulky.
The body combines aluminium alloy, IML, and PCTG materials, offering both durability and a premium feel. The metallic finish gives it a luxurious appearance, while the curved edges add a modern and ergonomic touch. Every corner and surface has been crafted to exude sophistication.
One of the standout visual elements is the droplet-shaped e-liquid window, allowing you to check your e-juice level at a glance. It’s a small but practical detail that keeps you from running dry mid-session. Every aspect of the G4 Pro’s construction screams attention to detail—from its seamless finish to the balance of texture and weight.
Smart Touchscreen Interface
The Uwell Caliburn G4 Pro takes innovation to the next level with its 2.51-inch full-touch display, making it one of the first pod systems to feature a true smart screen. Gone are the days of complicated button combinations or blinking LED indicators. With this interface, every setting is literally at your fingertips.
The touchscreen allows users to adjust wattage, switch modes, reset puff counters, and view essential data like battery life and puff time—all through an intuitive and responsive interface. Navigation feels smooth, and the device reacts instantly to touch gestures.
A unique addition is the multi-theme customization. The G4 Pro includes six visual themes to personalize your vaping experience. Three are available right out of the box, while the remaining three unlock automatically as you continue to vape, rewarding consistent use.
The interface also supports multiple languages, including English, Arabic, French, Spanish, Italian, Russian, German, and Indonesian. This broad accessibility shows that Uwell designed the Caliburn G4 Pro with global users in mind.
Swiping down on the home screen brings up a convenient quick-settings menu where you can adjust brightness, screen timeout, and device name. This kind of personalization is rare in pod systems and makes the G4 Pro feel more like a smart device than a simple vape.
Intelligent Output Modes
Performance has always been the heart of the Caliburn series, and the G4 Pro doesn’t disappoint. Equipped with an 1800 mAh built-in battery and up to 35 watts of output, this pod kit is designed to handle both flavor-focused and performance-driven vaping styles.
To deliver a customized experience, the G4 Pro features three distinct output modes:
- Storm Mode – Delivers a quick, strong throat hit with dense vapor. Ideal for users who prefer a bold, instant draw.
- Waves Mode – Produces a smoother, more consistent puff with balanced flavor and vapor production.
- Custom Mode – Offers full control over wattage and vapor curve. You can fine-tune the start, middle, and end of each puff for a completely personalized experience.
Each mode caters to a different style of vaping, from sharp and intense hits to calm and flavor-rich sessions. Switching between modes is effortless through the touchscreen interface.
The device also incorporates PRO-FOCS 4.0 flavor technology, ensuring that every puff delivers pure, authentic taste. This technology optimizes the heating process, enhancing the natural notes of your e-liquid without burning or distortion.
Adjustable Airflow for MTL and RDL
Flexibility is another highlight of the Uwell Caliburn G4 Pro. With its stepless airflow adjustment system, users can precisely control the air intake to suit either MTL (mouth-to-lung) or RDL (restricted direct-lung) vaping.
A small slider allows you to fine-tune your airflow preference—from tight, cigarette-like draws to airy, cloud-friendly puffs. This versatility makes the device suitable for both nicotine salt and freebase e-liquids, accommodating a wide range of vaping styles.
Whether you prefer discreet sessions or want to chase more vapor, the airflow control ensures that the G4 Pro delivers consistently satisfying performance every time.
Pod and Coil Compatibility
One of the major strengths of the Caliburn G4 Pro is its compatibility with the G-series platform. The device uses GPP (G Pod Platform) cartridges, which means it supports a wide range of coils and pods used in previous Caliburn G models.
Compatible Coil Options:
- 0.4 Ω mesh coil – for RDL vaping and dense clouds.
- 0.6 Ω mesh coil – balanced for both flavor and vapor.
- 0.9 Ω coil – ideal for classic MTL vaping and smooth nicotine salt delivery.
- 1.2 Ω coil – delivers a tighter draw and more discreet vapor output.
This backward compatibility means you can reuse your favorite GPP pods and coils, reducing waste and keeping maintenance simple.
The pod itself features U² Anti-Leak Technology, combining ultrasonic welding with a U-shaped channel to minimize leaks and condensation. It’s a big improvement over earlier designs and keeps your hands and pocket clean.
With a 3 mL e-liquid capacity, the pod holds enough juice for extended sessions, and refilling is quick and straightforward thanks to the side-fill system. You simply open the port, fill your e-liquid, and snap it closed—no spills, no mess.
Battery and Charging Efficiency
Power and convenience go hand in hand in the Caliburn G4 Pro. The device houses a built-in 1800 mAh battery, providing long-lasting performance throughout the day.
Depending on your wattage and mode settings, it can easily last for several hours of continuous use. Even heavy users will appreciate its endurance and consistency.
Charging is handled via a USB-C port, supporting 5V/2A fast charging. In most cases, you can recharge from 0% to full in under an hour, minimizing downtime. The large touchscreen also displays precise battery percentage, so you’ll always know when it’s time to plug in.
Battery management is further enhanced by power-saving options within the settings menu, helping extend lifespan and optimize performance. With this kind of power and intelligence combined, the G4 Pro feels more like a small vaping computer than a traditional pod kit.
Display Features and User Feedback
The bright, full-color touchscreen is more than just a design element—it’s a central control hub. It provides instant access to essential vaping data, including:
- Real-time wattage and voltage output
- Puff duration and counter
- Coil resistance
- Battery percentage
- Mode selection and theme visuals
The display is crisp and responsive, with excellent visibility even in bright environments. Haptic feedback adds a premium touch, giving a subtle vibration when you interact with the interface. These fine details show Uwell’s commitment to delivering a truly modern experience.
Color Options and Aesthetics
Aesthetics play a big role in the appeal of the Caliburn G4 Pro. The device is available in multiple striking color options, including:
- Ink Blue
- Light Green
- Fantasy Pink
- Desert Gold
- Iron Gray
- Pearl Silver
- Frost White
- Stripe Black
Each finish is elegant and vibrant, enhanced by the smooth metallic texture of the body. Whether you prefer subtle sophistication or something more expressive, there’s a G4 Pro color to match your personality.
The device’s compact and streamlined profile complements its vibrant palette, making it both a functional tool and a statement piece.

- Short-Circuit Protection
- Low Voltage Protection
- Over-Time Protection
- Open-Circuit Protection
- Overheating Protection
These automated systems monitor every puff, keeping the device safe even under demanding use.
User Experience
Using the Caliburn G4 Pro feels refined, intuitive, and modern. The draw activation is smooth, and vapor production is impressive for a compact device. Flavour remains crisp even at higher wattages, thanks to the mesh coils and PRO-FOCS technology.
The touchscreen simplifies every interaction—no need for complicated button sequences. You just tap, slide, and vape. Transitioning between different coil types or vaping styles takes seconds.
The adjustable airflow provides another layer of customization. Whether you prefer the tight resistance of an MTL inhale or the freer pull of an RDL hit, the G4 Pro adapts effortlessly.
Leak prevention is also worth praising. Thanks to the U² Anti-Leak structure, even after hours of use or travel, the pod remains clean and dry.
Why the Uwell Caliburn G4 Pro Stands Out
