When it comes to pod kits, Vaporesso has a strong track record of creating devices that balance simplicity, power, and design. The Vaporesso XROS 4 Nano Pod Kit takes that balance even further. Compact yet packed with performance features, it’s built for vapers who want more control over their experience without the bulk of a large mod.
This detailed guide covers everything you need to know about the XROS 4 Nano—its design, specifications, features, compatibility, and overall performance. Whether you’re switching from disposable vapes or upgrading from an older pod device, this model deserves your attention.
Design and Build Quality
The first thing you notice about the Vaporesso XROS 4 Nano is its distinct, square-shaped body. Measuring approximately 55.3 × 20.9 × 56.5 mm and weighing around 90 grams, it strikes the perfect balance between portability and durability. The compact structure makes it ideal for carrying in your pocket, bag, or hanging from the included lanyard.
Its aluminum-alloy frame feels premium and sturdy in hand. The matte and metallic finishes available across its color range add to its modern, stylish look. On one side of the device, you’ll find an airflow control slider that lets you fine-tune your draw. The front houses a circular fire button and a 1.3-inch TFT color screen that displays all your key vaping information.
The screen is one of the standout design upgrades. It’s bright, responsive, and customizable with different themes and animations, such as “Motorcycle,” “Universe,” and “Flower.” You can monitor wattage, puff count, and battery level in real time. For such a compact device, the inclusion of this kind of display is impressive.
Magnetic pod connection on the top ensures smooth attachment and removal. The XROS series has always been known for its clean magnetic pod design, and the XROS 4 Nano keeps that same convenience.
Performance and Specifications
The XROS 4 Nano delivers strong performance through its advanced internal hardware and Vaporesso’s reliable COREX 2.0 technology. Here’s a detailed look at what powers this pod kit:
- Battery Capacity: 1350 mAh built-in battery
- Charging Port: USB-C with 2A fast charging support
- Pod Capacity: 3 ml (standard) / 2 ml (TPD version)
- Output Power: Up to 30 W
- Resistance Range: 0.4 Ω – 1.2 Ω
- Pod Compatibility: Fully compatible with all Vaporesso XROS series pods
- Activation: Dual activation (draw and button-activated)
- Airflow: Adjustable slider for MTL and RDL draws
- Display: 1.3-inch TFT color screen
The large 1350 mAh battery is a big plus for users who want longer vaping sessions without recharging. On a full charge, the XROS 4 Nano can easily last a full day of regular use. When it does need charging, the Type-C 2A fast charge system ensures you’re back to full power in about 30–40 minutes.
Another advantage is the variable wattage control that activates automatically when using the 0.4 Ω pod. The device intelligently adjusts power between 15–30 W, depending on the coil and your draw style, giving you a smooth, tailored experience.
Vaporesso COREX 2.0 Technology
At the heart of the XROS 4 Nano is Vaporesso’s COREX 2.0 heating technology, designed to deliver consistent flavor and longer coil lifespan. The improved mesh coil structure heats e-liquid evenly, producing dense vapor while reducing burnt taste or dry hits.
The COREX 2.0 design also includes an updated cotton structure that locks in e-liquid more effectively. This keeps the coil saturated longer and extends pod life by as much as 30% compared to earlier versions.
For vapers who appreciate strong, clear flavor—especially when using nicotine salts or high-PG e-liquids—the XROS 4 Nano performs remarkably well. Each puff feels consistent, flavorful, and smooth from start to finish.
Adjustable Airflow and Versatility
One of the most notable features of the XROS 4 Nano is its airflow control. Located on the side, the slider lets you choose between a tight Mouth-To-Lung (MTL) experience and a more open Restricted Direct-To-Lung (RDL) style.
This flexibility makes it suitable for different vaping preferences. Close the airflow for a tighter draw similar to traditional cigarettes, or open it up for larger, airier clouds. Because it’s compatible with multiple coil resistances, you can easily switch between the two styles by changing pods.
The dual activation system is another nice touch. You can either press the fire button or simply inhale to activate. This adds a layer of convenience for users who prefer a buttonless experience.
Pod Compatibility
The Vaporesso XROS 4 Nano is compatible with all pods from the XROS family, including:
- XROS 0.4 Ω mesh pod (for more vapor and warmth)
- XROS 0.6 Ω mesh pod
- XROS 0.8 Ω mesh pod
- XROS 1.0 Ω pod
- XROS 1.2 Ω pod
This wide compatibility makes it easy to find your preferred balance of flavor, warmth, and draw resistance. Each pod features a top-fill system, which reduces leakage and mess. Just snap off the mouthpiece, fill your favorite e-liquid through the side hole, and you’re ready to go.
All pods use COREX 2.0 mesh coils, ensuring consistent performance across resistances. The 0.4 Ω pod supports variable wattage mode, while the others automatically adjust power for optimized flavor output.
What’s in the Box
When you purchase the Vaporesso XROS 4 Nano Pod Kit, you’ll find everything needed to get started right away:
- 1 × Vaporesso XROS 4 Nano Device
- 1 × XROS 0.4 Ω Mesh Pod (pre-installed)
- 1 × XROS 0.8 Ω Mesh Pod (spare)
- 1 × USB-C Cable
- 1 × Lanyard
- 1 × User Manual
This thoughtful packaging provides users with both a high-performance and moderate-resistance pod, allowing immediate experimentation between flavor intensity and draw preference.
Display and Interface
The 1.3-inch TFT screen is a refreshing upgrade from earlier models. It shows essential information like battery level, wattage, and puff count in a clear, colorful layout. Users can also switch between visual themes for a more personal experience.
Battery status is displayed in 1% increments, which is far more accurate than traditional battery bar indicators. This helps avoid unexpected power loss and keeps you informed throughout the day.
Battery Life and Charging
Battery performance is one of the XROS 4 Nano’s strongest features. Its 1350 mAh battery ensures steady output and long usage time. Depending on the coil and wattage level, you can expect anywhere from a full day to a day and a half of moderate vaping.
The 2A fast-charging system is another highlight. It can charge the device from 0 to 100% in around 30 minutes, significantly reducing downtime. The Type-C port also supports pass-through charging, allowing you to vape while plugged in.
Flavor and Vapor Production
Vaporesso’s reputation for flavor precision is well-earned, and the XROS 4 Nano reinforces that. The combination of COREX 2.0 coils, improved airflow design, and accurate wattage control produces rich flavor and dense vapor, especially when using the 0.4 Ω or 0.6 Ω pods.
For those who prefer nicotine salt e-liquids, the higher-resistance pods (0.8 Ω and above) deliver smooth, satisfying hits with strong flavor notes and minimal throat harshness. The vapor output is generous for a compact pod kit, making it a great choice for both casual and frequent users.
Color Options
Vaporesso has always paid attention to aesthetics, and the XROS 4 Nano continues that tradition with several unique color variants:
- Word-Pop Yellow
- Twilight Purple
- Camouflage Green
- Graphite Black
- Titanium Silver
- Race Track Grey
- Aquamarine
- Word-Pop Blue
Each color is bold yet refined, appealing to both minimalists and users who like their device to stand out. The finish is durable, scratch-resistant, and resists fingerprints remarkably well.
User Experience
Every aspect of the XROS 4 Nano has been designed for convenience. From the magnetic pod fitting and leak-resistant top-fill system to the intuitive interface, it’s a pod kit built for both beginners and experienced vapers.
The device automatically detects pod resistance and adjusts power accordingly, so there’s no need for manual tuning unless you want to fine-tune it yourself. The combination of draw and button activation gives flexibility, while the adjustable airflow slider allows easy customization on the go.
The pod system provides smooth, quiet draws without gurgling or spit-back. Vapor temperature remains consistent even during long sessions, and the coil life easily stretches to a week or more with proper maintenance.
