Uwell Caliburn G4 Pro: The Future Of Touchscreen Vaping

Vaping has evolved dramatically over the years, but few devices truly redefine the experience the way the Uwell Caliburn G4 Pro Pod Kit does. This latest addition to Uwell’s iconic Caliburn series merges powerful performance with intelligent technology, offering a seamless balance of innovation, style, and function.

The Caliburn line has long been known for delivering flavor-rich performance, and the G4 Pro takes that legacy to new heights with a full touchscreen interface, upgraded pod compatibility, and advanced output modes that allow users to fine-tune every puff. Whether you’re a long-time Caliburn fan or someone exploring pod systems for the first time, this device sets a new benchmark for modern vaping.

Design and Build Quality

At first glance, the Caliburn G4 Pro stands out for its minimalist yet premium design. Its sleek aluminum alloy frame, complemented by a polished finish, gives it a modern aesthetic while maintaining durability and portability. Despite being equipped with advanced hardware and a large battery, it remains surprisingly lightweight — perfect for daily use.

The most eye-catching feature is the 2.51-inch full-touch display, a first for the Caliburn series. This high-definition screen replaces the traditional button interface and gives users a smartphone-like experience. The display is protected by an ultra-shatter-resistant cover, ensuring long-term durability even with daily handling.

Uwell has also integrated a droplet-shaped e-liquid viewing window, allowing users to check their e-juice levels easily without removing the pod. The overall build feels ergonomic, and the smooth curves ensure that it fits comfortably in the hand — a small yet crucial detail that enhances everyday use.

Specifications and Technical Highlights

Under the elegant exterior, the Caliburn G4 Pro houses powerful internals that make it more than just a pretty device. Here’s a breakdown of its core specifications:

• Battery Capacity: 1800 mAh (built-in, rechargeable)
• Output Power: Up to 35 W
• Pod Capacity: 3 mL
• Display: 2.51-inch full touchscreen
• Charging Port: USB-C (fast charging support)
• Material Composition: Aluminum alloy, ABS, and PCTG
• Vaping Modes: Storm Mode / Waves Mode / Custom Mode
• Airflow Control: Stepless adjustable system
• Compatible Pods: Caliburn GPP pod cartridges (both standard and upgraded versions)

Every detail of this setup reflects Uwell’s focus on usability and innovation. The 1800 mAh battery ensures long vaping sessions, while the 35 W maximum output allows for a balance of flavor and vapor production. The USB-C port delivers faster charging, typically taking under 45 minutes to reach full charge, which is a major convenience for users on the go.

Touchscreen Interface and Smart Functionality

The introduction of a full touchscreen interface is one of the defining features of the Caliburn G4 Pro. With simple taps and swipes, users can control every aspect of the device — from power adjustment to mode switching — without relying on physical buttons.

The main menu offers quick access to wattage settings, puff counters, vaping modes, and battery status. Swiping down opens a quick-settings hub, where users can modify screen brightness, toggle animations, adjust timeouts, activate battery saver mode, or even rename their device. The UI also supports multiple languages, enhancing accessibility for global users.

To make the experience more engaging, Uwell has included unlockable UI themes. The device comes with three preset themes, and users can unlock three additional ones after reaching specific puff milestones (5,000 / 10,000 / 20,000 puffs). This small but fun detail adds a touch of personalization to the device.

Three Intelligent Vaping Modes

The Caliburn G4 Pro is engineered to adapt to any vaping style, thanks to its three intelligent output modes:

1. Storm Mode
This mode delivers instant, powerful hits with a strong throat impact. It’s designed for users who enjoy dense vapor and an intense draw. When you want that quick nicotine satisfaction and robust flavor delivery, Storm Mode brings the heat — literally and figuratively.

2. Waves Mode
Waves Mode offers a smoother and more balanced experience. The device gradually increases and decreases output during each puff, simulating the rhythm of natural breathing. The result is a wave-like sensation that highlights the subtle nuances of your e-liquid’s flavor profile.

3. Custom Mode
For those who love complete control, Custom Mode allows users to fine-tune the wattage at three points in each puff — the beginning, middle, and end. Whether you prefer a soft start and strong finish or vice versa, this level of customization ensures every vape session feels unique.

Together, these three modes make the G4 Pro one of the most versatile pod systems available, offering a tailored experience for every type of vaper.

Airflow System and Draw Control

Uwell has redefined airflow customization in the Caliburn G4 Pro. The device features a stepless airflow control slider that lets you fine-tune the draw resistance to your liking. By adjusting the slider or flipping the pod orientation, users can switch effortlessly between Mouth-to-Lung (MTL) and Restricted Direct-Lung (RDL) vaping styles.

This level of precision allows you to strike the perfect balance between tight flavor delivery and airy vapor production. The airflow mechanism operates smoothly and locks securely in place, ensuring consistent performance with every puff.

Pod Compatibility and Coil Options

The Caliburn G4 Pro is fully compatible with Uwell’s latest GPP Pod Platform, which includes both older and upgraded versions of the G series cartridges. This backward compatibility is a major advantage for users transitioning from previous Caliburn devices.

Each pod holds 3 mL of e-liquid and features an improved filling system that prevents leaks and spills. Uwell’s U² leak-resistant structure, which combines ultrasonic welding with a U-shaped airflow channel, minimizes condensation and keeps the pod clean during long-term use.

Available coil resistances typically include:

• 0.4 Ω – best for warm, dense vapor and restricted DTL hits
• 0.6 Ω – ideal balance between flavor and vapor
• 0.9 Ω – optimized for smooth MTL sessions
• 1.2 Ω – perfect for low-wattage, high-nicotine e-liquids

Thanks to Uwell’s PRO-FOCS 4.0 Flavor Technology, the G4 Pro delivers enhanced flavor clarity and consistency across all coil types. This system carefully controls heating temperature and airflow to preserve the original taste of your e-liquid, ensuring every puff feels fresh and satisfying.

Performance and Vaping Experience

When it comes to performance, the G4 Pro is an absolute powerhouse in its category. The combination of high wattage output, intelligent chip control, and superior coil design results in a vaping experience that’s both flavorful and efficient.

The 1800 mAh battery easily lasts through a full day of moderate use. Even heavy vapers will appreciate its quick USB-C recharging, which minimizes downtime. The touchscreen interface responds quickly, and there’s no noticeable lag when switching between modes or adjusting settings.

Flavor delivery is exceptionally clean. In Storm Mode, you get strong throat hits with thick vapor production, while Waves Mode provides smoother draws with better flavor layering. The Custom Mode is a delight for enthusiasts who enjoy experimenting with different power curves.

Additionally, Uwell’s advanced chipset includes comprehensive safety protections — overcharge, short-circuit, low-voltage, and overtime protection — ensuring worry-free vaping at all times.

Colors and Aesthetic Options

The Caliburn G4 Pro is available in a stunning array of color finishes to match your personal style. These include:

• Desert Gold
• Frost White
• Fantasy Pink
• Ink Blue
• Iron Grey
• Light Green
• Pearl Silver
• Stripe Black

Each color variant features a subtle metallic sheen and fine texture that enhance the premium feel. Whether you prefer something bright and eye-catching or a muted, professional tone, there’s a G4 Pro style for every taste.

Unboxing and What’s Included

Inside the box, you’ll find everything you need to start vaping right away. The package typically includes:

• 1 × Uwell Caliburn G4 Pro Device
• 1 × GPP Pod Cartridge (pre-installed)
• 1 × USB-C Charging Cable

The packaging itself is clean, compact, and environmentally conscious. Uwell’s attention to presentation adds to the premium unboxing experience, with every component neatly arranged and sealed for authenticity.

Ease of Use

Despite its advanced technology, the G4 Pro remains extremely user-friendly. The touchscreen interface is intuitive, with icons and menus that are easy to navigate. Switching between modes or adjusting power takes only a few taps, making it accessible even for users new to touchscreen vaping.

Refilling the pod is equally convenient. The top-fill or side-fill system (depending on region) allows refills without removing the cartridge, reducing mess and saving time. The pod clicks securely into place with magnetic connection points, ensuring perfect contact with the device.

Battery Life and Charging

Battery performance has always been a defining feature of the Caliburn line, and the G4 Pro continues that legacy. The 1800 mAh capacity provides extended vaping time, while USB-C fast charging ensures quick top-ups.

The device also includes a battery saver mode, which intelligently regulates power output and screen brightness to extend runtime. Users can monitor remaining charge directly from the display, complete with detailed battery percentage and estimated time remaining.

With its efficient power management and rapid recharge, downtime is practically eliminated — making it a great companion for travel or all-day vaping.

Safety Features

The G4 Pro integrates Uwell’s advanced chipset with multiple safety protections, including:

• Over-time protection
• Low-voltage protection
• Short-circuit protection
• Over-charge and over-discharge protection
• High-temperature cutoff

These safeguards work silently in the background to ensure stable, reliable operation under all conditions.
