Vaporesso XROS 4 vs XROS Pro

Introduction

The Vaporesso XROS 4 and XROS Pro sit inside the same product family, share the same universal XROS pod platform, and compete within a £1.50 price gap. Both are refillable pod kits designed for MTL (mouth-to-lung — a tighter, cigarette-like inhale) and RDTL (restricted direct-to-lung — slightly looser) vaping. Both support auto-draw and button activation, USB-C charging, and adjustable airflow.

The real differences are structural: the XROS 4 is lighter, slimmer, and confirmed aluminium. The XROS Pro has a larger battery, adjustable wattage, and a puff counter. This review examines every verifiable specification and practical trade-off so you can match the device to your daily habits — not to marketing claims.

Note: Flavour perception, hand feel, draw preference, and design taste are subjective. This review separates objective data from experience-based observations throughout.

Editorial Scores

Scores reflect editorial assessment based on verified specs and hands-on usage patterns. Subjective dimensions (flavour, throat hit) noted as such.

Design & Build Quality

Materials & Finish

The XROS 4 uses a confirmed aluminium alloy unibody with a seven-stage anodising process. This gives it scratch resistance that outperforms polycarbonate shells common at this price point. After weeks of daily pocket carry alongside keys and coins, the anodised surface shows minimal wear. The XROS Pro's body material is not specified as aluminium on its product page — we cannot confirm whether it matches the XROS 4's construction.

Dimensions & Portability

Both measure 120mm tall and 24mm wide. The critical difference is depth: the XROS 4 at 14mm slides into a trouser pocket without a visible bulge, while the XROS Pro at 18mm is noticeably thicker. The weight gap is significant — 53g versus 84g. The XROS 4 is nearly 40% lighter, which compounds over hours of hand-holding or pocket carry. However, some users prefer a device with more physical heft; lighter does not automatically mean better for everyone.

Colour Options

The XROS 4 ships in ten finishes including gradient options like Sunset Neon and Pastel Palette — visually striking but slightly more prone to showing fingerprints than solid colours. The XROS Pro offers nine solid colourways. All finishes on both devices use the same anodising process for their respective materials.

Some aspects such as hand feel, weight impression, and design preference are subjective and should be judged personally.

Configuration & Technical Structure

Battery & Charging

The XROS 4's 1000mAh cell supports 6–10 hours of use depending on pod resistance and vaping frequency. Moderate MTL users on a 0.8Ω pod typically reach a full working day. Its 2A USB-C charging completes in 30 minutes — one of the fastest in the refillable pod category. A 20-minute top-up during breakfast covers a morning commute.

The XROS Pro's 1200mAh battery extends runtime by roughly 20% under identical conditions, reaching approximately 8–12 hours for moderate users. Charging takes about 35 minutes. For heavy vapers on 0.4Ω pods who consume battery faster, the extra 200mAh can mean avoiding a midday charge entirely.

Coil Technology

The XROS 4 runs COREX 2.0 mesh coils — Vaporesso's updated heating element with refined grid sizing designed to match temperature to liquid viscosity. The brand claims 30% better flavour reproduction versus earlier XROS coils. Heating distributes across the full mesh surface, reducing localised hot spots that cause premature flavour degradation.

The XROS Pro uses mesh coil pods but does not carry the COREX 2.0 branding on its product page. Both systems use integrated coil pods — the entire pod is replaced rather than swapping a coil insert. This simplifies maintenance: no coil removal, no cotton handling, no priming individual coils.

Power Control

The XROS 4 cycles through three presets — Low, Medium, High — via double-clicking the fire button. Simple and fast. Low mode suits 0.8Ω pods for cooler MTL vaping. High mode pushes 0.4Ω and 0.6Ω pods to warmer, denser output at the cost of 20–30% faster battery drain.

The XROS Pro provides 5–30W adjustable wattage alongside Eco, Normal, and Power presets. The 0.4Ω pod unlocks manual wattage adjustment. For users who want to fine-tune vapour warmth for a specific throat hit intensity, this granularity is meaningful. For set-and-forget users, the presets cover everyday needs without learning a wattage curve.

E-Liquid Pairing & Flavour Performance

Both devices are refillable — flavour depends on your coil-liquid pairing, not a factory menu. Here is what works best with each pod resistance:

Flavour Notes

Mesh coils on both devices handle menthol and ice liquids cleanly — cooling effects come through without metallic distortion. Fruit profiles remain distinct at medium power. Heavily sweetened liquids shorten pod lifespan to under a week on either device (a universal mesh coil characteristic, not device-specific). Aftertaste is minimal with quality nic salt blends. For all-day vaping, moderately sweet fruit profiles hold up better than rich dessert flavours, which can feel cloying after several hours.

The XROS 4's COREX 2.0 coils are purpose-built for flavour consistency. Based on hands-on comparison, both devices perform reliably, but the XROS 4 shows a slight edge in retaining flavour clarity through the pod's second week of use.

Getting Started & First-Time Experience

Beginner-Friendliness

The XROS 4 is slightly easier for first-time refillable users — three presets require no wattage knowledge. The XROS Pro's adjustable wattage can feel unfamiliar initially, though its Eco/Normal/Power presets function as a safety net for those who prefer not to dial in numbers.

Common Pitfalls

Core Performance Review

Value for Money

The £1.50 price gap (£17.99 vs £19.49) is negligible. The real value question is refillable running cost versus disposables.

Market Popularity & Appeal

The XROS series is one of Vaporesso's longest-running pod platforms. Cross-compatible pods create a practical lock-in: buying into the XROS ecosystem means your pods work across the XROS 4, XROS 4 Mini, XROS Pro, XROS 5, and earlier models. This reduces waste and simplifies restocking — you carry one type of spare pod regardless of which device you own.

Both devices benefit from the UK market's ongoing shift from single-use disposables toward refillable systems, driven by environmental awareness and evolving regulatory guidance. At £15–£20, they compete with the Smok Novo range, GeekVape Wenax Q2, and Lost Vape Ursa Nano 3. Vaporesso differentiates through ecosystem breadth and COREX coil technology.

Expert Recommendation

Competitive Context

Both devices sit in the £15–£20 refillable pod kit bracket alongside the Smok Novo Classy (£18.99), GeekVape Wenax Q2 (£20.99), Lost Vape Ursa Nano 3 (£13.99), and Aspire PockeX (£16.99). Vaporesso's advantage is the XROS pod ecosystem — one pod type covers multiple devices, reducing the cost and complexity of carrying spares. Competing brands typically lock pods to a single model generation.

If neither the XROS 4 nor XROS Pro fits, VapeBus stocks the full Vaporesso range including the XROS 4 Mini (£12.49 — smaller form factor), XROS 5 (£22.99 — newer generation), and XROS Pro 2 (£24.99 — updated Pro model).
