In the fast-moving world of vaping, a device that blends strong performance with effortless simplicity is rare. The UWELL Caliburn G4 Mini Pod Kit captures that balance perfectly. It’s small, elegant, and packed with intelligent engineering designed to deliver smooth flavour and reliable satisfaction every single time.

The Caliburn line has already earned global respect for its consistency and flavour clarity. Each release in the series has built upon the previous one, refining airflow systems, coil design, and portability. The G4 Mini continues this legacy — only now, it’s lighter, sleeker, and surprisingly powerful for its size.

Whether you’re a new vaper seeking a stress-free setup or a long-time enthusiast looking for a dependable everyday device, the Caliburn G4 Mini stands out for its modern design, performance, and convenience. Let’s explore every detail that makes this little pod kit one of the most exciting compact systems on the market.

A Sleek Design That Feels Effortless

From the first touch, the Caliburn G4 Mini feels premium. The device measures roughly 112.7 mm tall, 24.1 mm wide, and 14 mm deep — compact enough to fit comfortably in any pocket while maintaining enough presence to hold securely in the hand.

Its chassis is crafted from durable polycarbonate and PCTG materials, giving it a smooth texture and a solid yet lightweight feel at about 46 grams. The minimalist design eliminates unnecessary buttons and screens. Instead, everything is clean, modern, and intuitive. You simply pick it up, draw, and enjoy.

Every curve on the body is refined for ergonomics. The mouthpiece has been reshaped for comfort, and the overall weight distribution makes long vaping sessions easy. The device strikes an ideal balance between simplicity and sophistication — proof that elegance doesn’t need to scream for attention.

Powerful Performance in a Pocket-Sized Device

Don’t let the small form fool you. Inside the slim frame sits an impressive 1100 mAh battery, capable of delivering up to 35 watts of output. That’s a serious amount of power for a device of this size, providing consistent vapour production and robust flavour throughout the day.

The G4 Mini charges quickly through a USB-C port, which ensures efficient energy transfer and less downtime between sessions. This makes it perfect for users on the go — a 20-minute top-up can easily last several hours of regular use.

Unlike older devices that needed a button to activate, this one relies on auto-draw firing. Simply inhale to start vaping — no switches or adjustments required. The chip instantly detects airflow and delivers an even, responsive output every time.

It’s built to suit both mouth-to-lung (MTL) and restricted direct-lung (RDL) styles, thanks to its versatile airflow system and wattage range. Whether you prefer a tight, cigarette-like pull or a slightly looser, flavour-dense puff, the G4 Mini adapts effortlessly.

Next-Generation Flavour Technology

UWELL’s flavour reputation is legendary, and with the Caliburn G4 Mini, they’ve raised the bar once again. The device uses the brand’s latest PRO-FOCS 4.0 flavour enhancement system, which optimises coil heating, airflow precision, and vapour condensation to deliver clearer, richer flavour profiles.

This upgraded system doesn’t just improve taste — it extends pod life as well. The G4 Mini’s cartridges have been engineered to last up to 35% longer than previous generations, helping users enjoy consistent flavour for more refills before needing replacement.

Each draw feels balanced — warm but not harsh, dense but not overwhelming. Even subtle notes in your e-liquid stand out cleanly. For those who appreciate smooth, accurate flavour reproduction, this little device offers performance that rivals many larger pod mods.

Smart Cartridge & Pod Compatibility

The G4 Mini uses UWELL’s newly upgraded Caliburn GPP pods, which feature refined coil design and advanced anti-leak engineering. The brand’s U² Leak-Resistant Technology combines ultrasonic welding and a U-shaped channel structure to seal liquid inside while maintaining ideal airflow. This innovation drastically reduces condensation and leakage — two issues that often frustrate pod users.

Each pod holds up to 3 mL of e-liquid (2 mL in TPD-compliant versions), giving users ample capacity for daily use. The transparent design lets you easily check your e-liquid level, so you always know when it’s time to refill.

Filling is done through a side-fill port, sealed by a tight silicone plug that prevents spills and keeps maintenance easy. Simply pop it open, top up your juice, and close — clean and efficient.

The G4 Mini remains fully compatible with previous Caliburn G3 pods, ensuring that existing Caliburn users can switch or upgrade without losing access to familiar cartridges. This cross-compatibility also expands your options for different coil resistances, allowing you to fine-tune your vaping style.

Customizable Airflow, Tailored Draw

One of the G4 Mini’s most appealing features is its dual-control airflow system. Most compact pod kits offer a single airflow style — the G4 Mini offers two ways to adjust it.

First, you can change pod orientation. Insert the pod one way for a tighter draw, flip it for a looser draw. It’s simple but effective.

Second, there’s a small airflow slider on the side of the device that provides finer control. By sliding it open or closed, you can adjust how much air passes through the chamber.

Together, these controls give you precise tuning between MTL and RDL experiences. You can start the day with a strong, cigarette-like pull and shift to a more open, airy draw in the evening — all without changing pods or devices.

The airflow feels balanced, smooth, and consistent, producing quiet draws with no whistling or turbulence. It’s this level of adjustability that makes the G4 Mini suitable for both beginners and experienced vapers alike.

Effortless Operation

Simplicity defines the entire experience. There are no menus, no wattage dials, and no complicated setup procedures. The device activates automatically with each inhale, so anyone can use it confidently within seconds of unboxing.

The pod connects magnetically to the device body — just snap it in, and it clicks securely in place. The magnetic design not only makes swapping pods fast but also prevents misalignment or loose fits.

The LED indicator on the body provides clear feedback about battery level and charging status. The light changes colour depending on how much power remains, so you’ll never be surprised by a low battery.

Every part of the G4 Mini’s interface is designed for convenience. Even maintenance feels minimal. A quick wipe occasionally keeps the connection points clean, and the rest is handled by the pod’s leak-resistant design.

Battery Life and Charging Efficiency

The internal 1100 mAh battery is a significant advantage for a pod of this size. Many mini devices hover around 700 mAh, but UWELL manages to fit nearly 60% more capacity without increasing bulk.

For light to moderate vapers, this battery easily lasts an entire day. Heavy users can still expect several hours of consistent use before recharging.

The USB-C port supports quick charging, and the port location at the bottom or side (depending on region) keeps the device stable while plugged in. A full charge typically takes around 45 minutes, but even a short 15-minute session can provide a noticeable power boost.

The chipset includes overcharge, short-circuit, and low-voltage protection, ensuring safe and reliable performance with every charge.

Colour Options and Personal Style

UWELL didn’t hold back when it came to aesthetics. The Caliburn G4 Mini is available in an impressive range of colour finishes — from bold metallics to subtle gradients. Some of the popular shades include:

• Night Black

• Slate Grey

• Bright Pink

• Grass Green

• Champagne Gold

• Phoenix Purple

• Peafowl Emerald

• Dusty Indigo

• Lake Blue

• Coast Gold

Each finish has a soft metallic sheen and smooth coating that resists fingerprints. These variations make it easy for users to choose a style that reflects their personality — whether minimalist, vibrant, or somewhere in between.

Inside the Box

Every Caliburn G4 Mini Kit includes everything you need to begin vaping immediately:

• 1 × Caliburn G4 Mini Device

• 1 × Caliburn GPP Pod (0.6 Ω coil pre-installed)

• 1 × USB Type-C Charging Cable

• 1 × User Manual

Some regional packages may differ slightly, but this setup ensures new users have the essentials ready to go right out of the box. Replacements and extra pods are readily available separately.

Durability and Maintenance

UWELL is known for solid build quality, and the G4 Mini continues that reputation. Despite its small size, it feels sturdy, with no rattles or loose parts. The magnetic pod housing holds strong, and the button-free body eliminates mechanical wear points that often fail in other devices.

Because the pod is transparent and side-filled, cleaning is easy. Occasional condensation can be wiped away with tissue or cotton swab, but the internal anti-leak structure already prevents most residue buildup.

This low-maintenance design is ideal for users who don’t want the hassle of frequent upkeep. The coil longevity, leak protection, and consistent airflow ensure a smooth experience week after week.

Optimizing Your Experience

To get the best results from your Caliburn G4 Mini, consider these simple tips:

1. Prime your pod – After filling, let the coil soak for a few minutes so the cotton absorbs e-liquid fully before first use.

2. Monitor your juice level – Refill before it runs completely dry to prevent burnt hits.

3. Use appropriate e-liquid – For MTL draws, use nicotine salts or 50/50 VG/PG blends. For RDL draws, slightly thicker e-liquids with higher VG will produce more vapour.

4. Adjust airflow – Experiment with both pod orientations and the slider to find your perfect draw resistance.

5. Charge responsibly – Avoid draining the battery completely before recharging to extend battery life.

6. Replace pods when flavour fades – Even with longer lifespan, replacing pods promptly maintains best taste.

7. Store upright – Especially during travel, keeping the device upright helps prevent any minor leakage.

Following these small steps will keep the device performing at its best and extend the overall life of your pods and battery.

Why the Caliburn G4 Mini Stands Out

Several factors make this kit shine in the crowded pod market:

• Compact yet powerful – Delivers 35 watts from a device barely larger than a pen.

• Superior flavour clarity – Thanks to PRO-FOCS 4.0 and improved coil technology.

• Dual airflow system – Offers flexibility rarely found in small pod devices.

• Longer pod lifespan – Saves money and reduces waste.

• Cross-compatibility – Works with G3 and GPP pods, giving users choice and convenience.

• Fast charging and long battery life – Keeps up with active users throughout the day.

• Premium design – Lightweight, stylish, and available in multiple colours.

Together, these features make the G4 Mini not just an upgrade, but a benchmark in compact pod vaping. It provides premium performance in an ultra-portable frame — the kind of balance few devices achieve.

Final Thoughts

The UWELL Caliburn G4 Mini Pod Kit isn’t just another mini vape; it’s a statement of refinement. It distills what makes the Caliburn line special — simplicity, taste, and build quality — into an even smaller, more capable format.

The device delivers a full day of power, incredible flavour, and leak-free reliability. Every aspect has been engineered for user convenience, from the smart magnetic connection to the adjustable airflow and quick USB-C charging.

For vapers who want a device that’s light in the pocket yet full in performance, the Caliburn G4 Mini represents one of the best compact pod systems available today. It proves that sometimes, less really is more — and that the smallest devices can still deliver the biggest satisfaction.
