This latest addition to the XROS family delivers the largest battery ever in the series, along with a vibrant 1.3-inch TFT color screen, making it a powerful choice for both beginners and experienced vapers.

Designed for mouth-to-lung (MTL) vaping enthusiasts, the XROS 4 Nano offers adjustable airflow, multiple pod options, and fast USB-C charging. These features work together to provide a reliable, flavorful vaping experience, whether you are at home, commuting, or traveling. Let’s explore what makes this pod kit a top choice in 2025.

Key Features of the XROS 4 Nano

The Vaporesso XROS 4 Nano packs several advanced features into a compact design:

1. High-Capacity Battery

This pod kit comes equipped with a 1350mAh built-in battery, the largest in the XROS series. The high-density battery supports long-lasting usage, allowing light to moderate vapers to enjoy multiple sessions without frequent recharging. Additionally, the fast-charging 2A USB-C port restores 80% of battery life in just 20 minutes. This combination of longevity and speed ensures you stay powered throughout your day.

2. 1.3-Inch TFT Color Display

The XROS 4 Nano features the largest circular TFT display in the series. It shows essential information such as wattage, battery status, puff count, and more. Users can also customize the display themes, choosing from options like Flower, Universe, and Motorcycle, adding a personal touch to the device. This screen enhances usability and provides a visually appealing experience.

3. COREX 2.0 Coil Technology

The kit includes the innovative COREX 2.0 mesh coil in its 0.4Ω pod. This upgraded technology offers optimized temperature matching and faster heating, resulting in richer flavor and more consistent vapor production. The refined cotton design prevents burnt taste and extends the pod’s lifespan by approximately 30%. With these coils, users enjoy enhanced aroma reproduction and improved vaping satisfaction.

4. Wide Pod Compatibility

The XROS 4 Nano works with all XROS pods, including 0.4Ω, 0.6Ω, 0.8Ω, 1.0Ω, and 1.2Ω options. The pods have a capacity of 3ml or 2ml depending on the regional regulations. This flexibility allows users to select the pod resistance and e-liquid strength that best suit their preference, whether they enjoy nicotine salts or freebase e-liquids.

5. Adjustable Airflow

Vapers can fine-tune the draw using the side airflow control. The device supports both tight MTL hits and slightly looser restricted direct-to-lung (RDL) draws. By adjusting the airflow, users can create a customized vaping experience that balances vapor production and flavor intensity.

6. Dual Activation Modes

The XROS 4 Nano offers both button activation and inhale-to-vape functionality. This dual system provides convenience and flexibility, allowing vapers to switch between modes depending on their situation or preference. Beginners, in particular, appreciate the simple inhale-to-vape option.

7. Lightweight and Portable

Despite its advanced features, the XROS 4 Nano remains compact and lightweight. Measuring 55.25 × 20.9 × 56.5 mm and weighing around 90g, it fits comfortably in pockets or bags. Its portable design ensures that you can carry it anywhere without compromising performance.

Battery Performance and Charging

Battery performance is crucial for pod kits, and the XROS 4 Nano delivers impressively. The 1350mAh battery supports up to four days of light usage on a single charge. Even with moderate vaping, you can rely on the device for a full day without interruptions. For heavy users, the USB-C fast-charging capability ensures minimal downtime, with the device reaching 80% charge in just 20 minutes.

This combination of long battery life and rapid charging makes the XROS 4 Nano highly convenient for daily use. Whether commuting, working, or traveling, you can confidently carry the device without worrying about frequent charging stops.

Flavor and Vapor Production

The COREX 2.0 mesh coil technology elevates flavor production in the XROS 4 Nano. The refined mesh structure and upgraded cotton optimize temperature and e-liquid delivery, producing richer, smoother flavor with every puff. Users report enhanced aroma reproduction, making fruits, desserts, and tobacco blends taste more vibrant and satisfying.

Moreover, the adjustable airflow system allows you to control vapor density. By narrowing the airflow for a tighter MTL draw, the flavor becomes more concentrated. Conversely, opening the airflow slightly creates a bigger vapor cloud without sacrificing taste, perfect for those who enjoy a slightly more airy draw.

Pod Options and Versatility

The Vaporesso XROS 4 Nano supports multiple pod resistances:

  • 0.4Ω mesh pod (pre-installed in CRC kit)

  • 0.6Ω mesh pod

  • 0.8Ω mesh pod

  • 1.0Ω pod

  • 1.2Ω pod

These options cater to various vaping preferences, from tight MTL hits to slightly more open draws. Each pod can hold 3ml of e-liquid, or 2ml for TPD-compliant regions. Users can easily switch pods depending on flavor or nicotine strength preferences, making the kit highly versatile.

Design and Build Quality

The XROS 4 Nano combines sleek aesthetics with practicality. Its ergonomic design ensures comfortable handling, while the durable construction prevents accidental damage. The device comes in several stylish finishes, including Graphite Black, Titanium Silver, Twilight Purple, Aquamarine, and more, allowing vapers to match their device to their style.

Additionally, the TFT screen and customizable themes enhance both form and function. With real-time display of wattage, battery, and puff count, users have complete control over their vaping experience at a glance.

Ease of Use

One of the strengths of the XROS 4 Nano is its user-friendly interface. Beginners benefit from the inhale-to-vape function, while advanced users can adjust wattage in 0.5W increments for the 0.4Ω pod. The three power modes — ECO, Normal, and Power — help tailor the device to different vaping styles, whether prioritizing battery life or maximum flavor output.

Filling the pods is straightforward, and the device comes with a lanyard for easy carrying. Overall, Vaporesso has designed the XROS 4 Nano to provide a seamless, intuitive vaping experience.

Maintenance and Longevity

Maintaining the XROS 4 Nano is simple. Regularly cleaning the pods and contacts ensures consistent performance and extends device lifespan. Using the correct pod resistance for your e-liquid type prevents burnt coils and preserves flavor quality. Proper priming of pods before use also avoids dry hits and enhances coil longevity.

With care, the XROS 4 Nano’s COREX 2.0 pods can provide reliable performance and extended use, giving vapers excellent value over time.
