Introduction

OnePlus has added a new, highly practical accessory to its lineup—the 2‑in‑1 SUPERVOOC Cable. This unique dual‑charging cable enables charging both a smartphone and a smartwatch using a single cable. It aims to reduce cable clutter during travel and everyday use.

Technical Features & Design

Length & Design

The cable measures 120 cm, offering ample reach between a power outlet and devices during travel.

Bulk USB‑A Connector

One end features a USB‑A connector, compatible with most legacy chargers and power adapters.

Dual Output End

The other end provides two outputs:

USB‑C for smartphones
Magnetic POGO‑pin for smartwatches
The magnetic POGO‑pin attaches easily to OnePlus Watch models (Watch 2, 2R, Watch 3, and 3 43 mm).

Charging Capabilities

Scenario	Smartphone	Smartwatch
Phone only	Up to 80 W SUPERVOOC fast charging	—
Phone + Watch	67 W	10 W via magnetic pin

When both devices are charged simultaneously, performance dips slightly, but charging speeds remain high and satisfactory.

Safety & Build Quality

E‑marker Smart Chip
Each cable is equipped with an E‑marker chip to prevent overcharge and ensure stable power delivery.
Pure Copper Core
The internal wiring uses pure copper, enhancing thermal efficiency and energy transmission.
Sturdy Construction
Featuring OnePlus’s signature red‑and‑white theme, it has a durable silicone outer layer and robust build.

Price & Availability

OnePlus is selling this cable in the United States for $29.99 (approx. ₹2,500), the same price as the OnePlus Watch charging base. It’s available on OnePlus’s official website and store, ensuring buyers receive a certified accessory with confidence.

In India, no official local launch has been announced yet. However, once available internationally, it is likely to appear on OnePlus India’s site or platforms like Amazon and Flipkart. For reference, a standard OnePlus Type‑A to Type‑C cable in India is priced at ₹849, giving a sense of the pricing range for this dual‑output cable.

If officially launched in India, it may cost between ₹2,500–₹3,000, and promotional offers or bank discounts could make it even more competitive. Authorized retail partners and online platforms would also offer warranty support.

User Benefits

Reduced Cable Clutter
No need to carry separate chargers for phone and watch—ideal during travel.
Fast Charging for Two Devices
Supports 80 W for phones alone, and 67 W + 10 W when charging both simultaneously.
Reliability & Safety
E‑marker chip and copper core provide a secure and dependable charging experience.
Durable and Stylish Design
Strong silicone coating and appealing aesthetics make it attractive and long-lasting.

Limitations Worth Noting

USB‑A Based
The reliance on USB‑A connectors may necessitate keeping a USB‑A brick; USB‑C bricks are growing more common.
OnePlus-Only Compatibility
The cable is compatible only with OnePlus brand phones and watches and may not work with other brands.

USB‑A Based

The reliance on a USB‑A connector means users must ensure they have an appropriate USB‑A power brick to fully utilize this cable’s capabilities. While USB‑A remains widespread, the market is rapidly shifting toward USB‑C and GaN-based chargers for convenience and power efficiency . USB‑C bricks are becoming the norm, with the global Type‑C charger market expected to grow by around 18% in 2025 alone . As USB‑A ports phase out in newer adapters and GaN chargers, users may need to retain older bricks or use adapters for compatibility.

OnePlus‑Only Compatibility

This cable is tailored specifically for OnePlus devices: it supports POGO‑pin charging for OnePlus Watch models and SUPERVOOC fast‑charge protocols exclusive to OnePlus phones. Third-party phones and smartwatches are unlikely to benefit from its full charging speeds or could even face compatibility issues . In particular, using non‑OnePlus bricks or third‑party phones may restrict charging to much slower rates (around 18 W), making the dual‑device fast‑charging feature moot

Conclusion

The OnePlus 2‑in‑1 SUPERVOOC Cable is truly a boon for users of both OnePlus smartphones and smartwatches. Key highlights include:

120 cm length
80 W fast charging for phones
67 W + 10 W dual-device charging
E‑marker chip safety
Solid construction

These features highlight OnePlus’s goal to enhance convenience, reduce cable clutter, and simplify travel. At around ₹2,500, it offers fast, safe, and efficient charging.

If you use a OnePlus phone and watch, this sleek, reliable accessory is definitely worth considering—it can help streamline your charging routine and solve many daily charging hassles.
