A Modern Take on Compact Vaping

The Uwell Caliburn G4 Pro is not just another pod kit. It’s built as a smart, powerful, and highly customizable compact device that fits easily into daily routines, yet offers features that rival advanced pod mods.

From the moment you pick it up, you’ll notice how refined and premium it feels. The mix of metallic and durable materials gives it a professional appearance, while still maintaining the lightweight feel Caliburn users are familiar with.

Design & Build Quality

Premium Material Construction

The G4 Pro uses a combination of:

• Aluminium Alloy
• ABS
• IML finishing
• PCTG pod materials

These materials ensure durability, resistance against scratches, and a comfortable feel in hand. The balance between metal and high-grade plastic keeps the device lightweight without compromising strength.

Modern Shape & Ergonomics

The device maintains the compact shape Caliburn fans love, yet offers:

• A wider comfortable grip
• A sleek, curved body
• A liquid-level window shaped like a droplet
• A centered screen for symmetry

Despite offering more internal hardware than previous models, the G4 Pro still feels portable and pocket-friendly.

Touchscreen – The Star of the G4 Pro

The biggest upgrade in the Caliburn lineup is unquestionably the full touchscreen interface. It replaces traditional buttons and delivers an entirely new experience in pod vaping.

Ultra-Responsive Display

The display is smooth, sharp, and reacts instantly to touch. Adjusting watts, changing modes, sliding menus, or viewing puff data feels natural and intuitive. Users no longer need to click a physical button multiple times — simply tap the screen.

Customizable User Interface

The G4 Pro allows you to personalize your device with:

• 6 UI themes (3 available instantly, 3 unlock as you vape)
• Animated transitions
• Brightness control
• Screen timeout options
• Battery saver settings
• Language selection (8 languages)
• Personal device naming using an on-screen keyboard

This level of personalization is extremely rare in compact pod kits.

Smart Settings Hub

A single swipe brings you to the “Settings Hub” where you can control:

• Power modes
• UI themes
• Language
• Puff reset
• System optimization
• Screen adjustments

This makes the G4 Pro feel like a hybrid between a smartphone and a vape.

Power Output & Performance

Up to 35W of Output Power

This makes it suitable for:

You can switch between three different modes:

1. Storm Mode

Battery Life & Fast Charging

1800mAh Built-In Battery

One of the largest batteries in the pod-vape category, providing:

• All-day vaping for most users
• Reliable performance even at higher wattages

Power efficiency is enhanced through:

• Smart battery optimization

USB-C Fast Charging

The USB-C port supports fast charging, so the device charges significantly faster than previous generations. This reduces downtime and keeps your pod kit ready for heavy use.

Airflow System – Versatility at its Best

The adjustable airflow offers stepless control, meaning you can fine-tune the draw exactly as you like:

• Fully closed = tight and cigarette-like MTL
• Half open = balanced and smooth
• Wide open = airy RDL experience

This flexibility makes the G4 Pro appealing to both beginners and seasoned vapers.

GPP Pod Platform – The Next Evolution

The new GPP Pod Series is designed exclusively for the G4 line, delivering better performance and leak resistance.

Coil and Pod Options

The kit supports multiple resistances, offering true flexibility:

Every coil is mesh-based, enhancing vapor production and ensuring fast heating.

PRO-FOCS 4.0 Flavor Technology

The pods use Uwell’s latest PRO-FOCS 4.0 flavor engine, which ensures:

• More accurate flavor notes
• Faster coil saturation
• Consistent flavor throughout the coil’s lifespan

Anti-Leak Technology

The GPP pods feature:

• Upgraded seal rings
• A stable internal pressure system
• Reinforced fill-port locks

This minimizes messy leaks and significantly improves pod longevity.

E-Liquid Capacity & Refilling

Pods offer a generous 3ml capacity (depending on region).
You can fill through:

• Top-fill or
• Side-fill (varies by pod type)

The e-liquid window on the device makes it very easy to monitor levels.

Flavor Experience – What to Expect

The Caliburn G4 Pro is designed for vapers who value flavor above all. With mesh coils and PRO-FOCS technology, each puff is smooth, warm, and richly saturated.

Best E-Liquids to Use

• Nic Salts 20–50mg (for MTL coils)
