Vaporesso’s XROS lineup has become one of the most popular pod system families on the market, and for good reason. These compact, refillable devices strike an ideal balance between simplicity and performance, making them a favorite among beginners and experienced vapers alike. But with multiple models available, choosing the right XROS device can feel overwhelming. In this comprehensive comparison, we break down the XROS Pro 2, XROS 5 Nano, XROS 5 Mini, XROS 4 Mini, and ECO Nano 2 so you can make a confident decision.
Okay, I have to be upfront here — I’m borderline obsessed with the XROS line. My XROS 4 Mini has been in my pocket every single day for the past fourteen months. It’s survived being dropped in a parking lot, going through the wash once (not recommended, but it lived), and being accidentally sat on more times than I’d like to admit. I’ve tried pod systems from SMOK, VOOPOO, GeekVape, you name it — and I keep coming back to the XROS. So yeah, this comparison is written by someone who genuinely loves this product family. I’ll still be honest about each model’s drawbacks, but you should know where I’m coming from.
Why Choose the Vaporesso XROS Series?
Before comparing individual models, it is worth understanding what makes the XROS series stand out from the competition. Every device in the lineup shares a few core strengths:
- SSS Leak-Resistant Technology – Vaporesso’s proprietary system minimizes condensation and leaking
- COREX Heating Technology – Delivers faster, more even heating for better flavor
- Draw-Activated and Button-Activated Options – Flexibility in how you vape
- Refillable Pods – Save money compared to disposables by using your own e-juice
- Wide Compatibility – Most XROS pods work across multiple devices in the series
XROS Pro 2 – The Flagship Performer
The XROS Pro 2 sits at the top of the lineup as Vaporesso’s most feature-rich pod system. It is designed for vapers who want premium build quality, advanced features, and the best possible flavor from a compact device.
Key Specifications
- Battery: 1000mAh
- Pod Capacity: 3mL
- Output: Adjustable wattage
- Charging: USB-C fast charging
- Coil Options: 0.4 ohm mesh, 0.6 ohm mesh, 0.8 ohm mesh, 1.0 ohm
- Display: OLED screen showing battery, wattage, and puff count
The standout feature of the Pro 2 is its adjustable wattage and OLED display, which gives you precise control over your vaping experience. The 1000mAh battery comfortably lasts a full day for most users, and the wide range of coil options means you can fine-tune your draw from a tight MTL to a loose restricted direct-lung hit. If you want the ultimate XROS experience and do not mind paying a bit more, the Pro 2 is the clear choice.
XROS 5 Nano – Ultra-Portable Simplicity
The XROS 5 Nano takes the latest fifth-generation XROS technology and packs it into the smallest form factor in the series. This is the device for vapers who value portability above all else.
Key Specifications
- Battery: 1000mAh
- Pod Capacity: 2mL
- Output: Fixed wattage
- Charging: USB-C
- Coil Options: 0.6 ohm mesh, 0.8 ohm mesh
- Activation: Draw-activated only
Despite its compact size, the XROS 5 Nano does not sacrifice battery life thanks to its efficient 1000mAh cell. The draw-activated firing mechanism keeps things simple — just inhale and enjoy. The 2mL pod capacity is slightly smaller than other models, but refilling takes just seconds with the top-fill design. This is an excellent choice for vapers who want something discreet enough to carry anywhere.
XROS 5 Mini – The Sweet Spot
The XROS 5 Mini bridges the gap between the ultra-compact Nano and the feature-rich Pro 2. For many vapers, this model hits the sweet spot of size, performance, and features.
Key Specifications
- Battery: 1000mAh
- Pod Capacity: 2mL
- Output: Fixed wattage with pulse mode
- Charging: USB-C
- Coil Options: 0.6 ohm mesh, 0.8 ohm mesh, 1.0 ohm
- Activation: Draw-activated and button-activated
The Mini offers both draw-activated and button-activated firing, which gives you more control compared to the Nano. It also supports an additional 1.0 ohm coil option for a tighter, more cigarette-like draw. The pulse mode feature delivers a quick boost of power at the start of each puff for faster flavor delivery. If you want fifth-generation XROS performance without the bulk or price of the Pro 2, the XROS 5 Mini is a compelling option.
XROS 4 Mini – Proven Reliability
This is my baby. I’ve been carrying an XROS 4 Mini since they launched and I genuinely can’t think of a single week where it let me down. My wife actually bought me the XROS 5 Mini as a birthday gift because she was tired of seeing the scratched-up 4 Mini on the nightstand, but I keep both charged. There’s something about the 4 Mini’s draw — slightly tighter than the 5 series — that just hits different with a 35mg nic salt. The 0.8 ohm mesh coil with a 50/50 juice is, in my opinion, the best mouth-to-lung experience you can get under $30. I’ve converted at least six coworkers to this exact setup.
The XROS 4 Mini represents the previous generation of Vaporesso’s compact pod systems. While it lacks some of the latest fifth-gen features, it remains a reliable and affordable option that many vapers continue to prefer.
Key Specifications
- Battery: 1000mAh
- Pod Capacity: 2mL
- Output: Fixed wattage
- Charging: USB-C
- Coil Options: 0.6 ohm mesh, 0.8 ohm mesh
- Activation: Draw-activated and button-activated
The XROS 4 Mini delivers consistent performance at a lower price point than the newer fifth-generation models. If you are budget-conscious and do not need the latest features, this model offers excellent value without compromising on the core XROS experience.
ECO Nano 2 – Budget-Friendly Entry Point
The ECO Nano 2 is Vaporesso’s most affordable pod system, designed to offer a quality vaping experience at an entry-level price. It strips away extra features to focus on what matters most: good flavor, reliable performance, and ease of use.
Key Specifications
- Battery: 1000mAh
- Pod Capacity: 2mL
- Output: Fixed wattage
- Charging: USB-C
- Coil Options: 0.8 ohm mesh
- Activation: Draw-activated only
The ECO Nano 2 is the simplest device in the lineup, with a single coil option and draw-activated firing. This simplicity is actually its strength — there are no settings to configure and no buttons to press. Just fill the pod, insert it, and vape. For first-time vapers or anyone who wants a hassle-free experience at a low price, the ECO Nano 2 is the ideal starting point.

Pair Your XROS With the Right E-Liquid
No matter which XROS model you choose, the right e-liquid makes all the difference.
