Pod systems have evolved dramatically over the years, but only a few brands consistently push the boundaries of design and performance. Uwell’s Caliburn series is one of those rare lineups that remains highly trusted among beginners and experienced vapers alike. With the release of the Caliburn G4 Pro, Uwell steps into a new era—introducing advanced personalization, a full touchscreen interface, a strong battery upgrade, refined airflow, anti-leak engineering, and intelligent flavor technology.

This blog covers everything you need to know about the G4 Pro, including its design, performance, technical specifications, compatible items, pod technology, color options, packaging, usability, and real-world experience. It is written in a professional and detailed tone so you can use it as publish-ready content on your vape platform.

Introduction to the Uwell Caliburn G4 Pro

The Uwell Caliburn G4 Pro Pod Kit is a modern, flagship-level pod system built for vapers who want more customization, better performance, and a smarter vaping experience. Uwell has retained the simplicity and portability that made Caliburn famous but added several premium upgrades, including:

  • A responsive touchscreen

  • 1800mAh battery

  • Three unique vaping modes

  • Adjustable airflow

  • GPP Pod compatibility

  • Leak-resistant engineering

  • Multiple UI themes

  • Personalization features

  • Rich flavor optimization technology

The result is a pod kit that feels fresh, futuristic, and capable of replacing traditional MTL and RDL setups for everyday use.

Design & Build Quality – A Modern Take on the Classic Caliburn Style

One of the first things you notice about the Caliburn G4 Pro is how refined and premium it feels. Uwell uses a blend of durable and lightweight materials including aluminum alloy, ABS, and PCTG to give it a clean metal finish with excellent structural strength. It is lightweight enough for pocket carry yet sturdy enough for daily use.

Premium Touchscreen Addition

The standout feature is the 2.51-inch touchscreen, a first in the Caliburn series. The display is vibrant, sharp, shatter-resistant, and designed to provide a smartphone-like experience but in a compact vape device.

You can adjust wattage, switch modes, view battery details, change themes, rename the device, and manage puff data—all with smooth touch interactions. Unlike other pod mods that hide functionality behind button combinations, the G4 Pro makes everything accessible with a tap or swipe.

User Interface & Personalization Options

A unique feature of the G4 Pro is its customization ability. Uwell clearly wanted vapers to make their devices truly personal.

Key Personalization Features Include:

Six UI Themes

Three themes come unlocked, and three unlock as you hit certain puff milestones. This gamification element adds a fun, interactive touch.

Adjustable Screen Brightness

Perfect for saving battery or increasing visibility outdoors.

Screen Timeout Options

Choose how long the screen stays active.

Animation Controls

Enable or disable UI animations depending on your preference.

Rename the Device

The built-in keyboard allows you to set a custom name. This is a small but impactful touch that makes the device feel more premium.

Multi-language Support

The device supports eight languages, including English, Arabic, French, German, Italian, Spanish, Russian, and Indonesian. This makes the G4 Pro globally accessible and user-friendly.

Battery Performance – Power That Lasts All Day

Battery life is one of the biggest improvements in the G4 Pro. It comes equipped with an 1800mAh built-in battery, significantly larger than previous models in the Caliburn series.

What This Means For You:

  • All-day use for MTL vapers

  • Excellent longevity for light and moderate users

  • Rapid charging with a Type-C 5V/2.5A port

  • More power to support higher wattage and “Storm Mode”

The Type-C port ensures efficient charging, reducing downtime and keeping you vaping longer.

Vaping Modes – A Device That Adapts to Your Style

The Caliburn G4 Pro offers three distinct vaping modes, letting you fine-tune your experience based on your mood or preferences.

1. Storm Mode

A high-impact, intense flavor mode. Ideal for those who want a stronger throat hit or denser vapor.

2. Waves Mode

Designed for balance—smooth, flavorful, consistent. Great for daily use or for vapers who prefer a mellow vaping style.

3. Custom Mode

This is one of the most advanced features of the G4 Pro.
You can adjust the power curve at three stages of each puff:

  • Beginning

  • Middle

  • End

This provides complete control over your vape experience, allowing you to create a fine-tuned puff pattern. It's a feature normally found in expensive vape mods, not compact pod systems.

Flavor Output & Performance – Powered by Pro-FOCS 4.0 Technology

Uwell is known for its Pro-FOCS flavor technology, and the G4 Pro uses the upgraded 4.0 version. This new iteration enhances coil longevity, boosts flavor accuracy, and optimizes vapor consistency.

What Makes the Flavor So Strong?

  • Enhanced coil materials

  • Better airflow structure

  • Power stability across puffs

  • Intelligent flavor calibration

  • Compatibility with multiple coil resistances

Whether you’re using nic salts or freebase, the G4 Pro delivers clean, rich taste with each puff.

Airflow System – Stepless Airflow for Precision Control

The Caliburn G4 Pro includes a stepless airflow control slider, allowing for everything from tight MTL draws to restricted DTL pulls. This flexibility means:

  • Smooth, cigarette-like puffs for beginners

  • Airy, cloudy draws for advanced users

  • Adjustable throat hit

  • Enhanced flavor refinement

  • Perfect tuning for different coil resistances

The airflow ring is responsive and holds its position well, avoiding accidental changes during pocket carry.

Leak Prevention – U² Anti-Leak Technology

Leaks are one of the biggest problems in pod systems, and Uwell directly addresses this with its U² Anti-Leak Engineering.

This includes:

  • Upgraded internal pod structure

  • Pressurized liquid channels

  • Improved condensation collection

  • Ultrasonic welding on the pod sides

  • Better sealing around coil contacts

These improvements prevent e-liquid seepage, extending coil life and keeping the device clean.

Pod & Coil Compatibility – The GPP Pod Platform

One major advantage of the Caliburn G4 Pro is its compatibility with the GPP Pod Platform. This means it supports multiple pod options, making it more versatile than previous Caliburn models.

Supported Coil Resistances:

  • 0.4Ω Mesh Coil (Warm, cloudy, excellent for RDL)

  • 0.6Ω Mesh Coil (Balanced, great for boosted MTL)

  • 0.9Ω Mesh Coil (Everyday MTL flavor enhancement)

  • 1.2Ω Coil (Tight MTL, smooth and discreet vaping)

Pod Capacity:

  • 3ml capacity for long vaping sessions

Refill Style:

  • Side-fill port for mess-free and quick refilling

Connection Type:

  • Strong magnetic connection for secure pod placement

The combination of multiple coil options and advanced flavor engineering makes the G4 Pro suitable for a wide range of vaping styles.

Color Variants – Style That Fits Your Personality

The Uwell Caliburn G4 Pro comes in eight beautiful color options:

  • Desert Gold

  • Frost White

  • Fantasy Pink

  • Ink Blue

  • Iron Gray

  • Light Green

  • Pearl Silver

  • Stripe Black

Each finish is polished, premium, and made with high-quality materials. Whether you like something bold or minimalistic, there’s a color to match your style.
