This article covers Belkin BoostCharge Pro 編組USB-C to デュアルUSB-Cケーブル 最大140Wスマート電力共有対応 超高耐久 ナイロンブレイデッド 1.5m ブラック CAC004fq1.5MBK.

Overview

The Belkin BoostCharge Pro Braided USB-C to Dual USB-C Cable (model CAC004fq1.5MBK) is a clever charging solution that lets you power two USB-C devices from a single cable. It supports up to 140W USB-C Power Delivery and features Smart Power Sharing, which automatically detects connected devices and distributes power optimally — for example, 100W + 40W or 60W + 60W. This makes it ideal for travelers or desk workers who need to charge a laptop and a phone simultaneously without carrying multiple cables. The cable is 1.5 meters long, made with a tough braided nylon exterior reinforced with recycled GRS materials, and has passed 350,000+ bend tests. Belkin guarantees 2 years of reliability, and the packaging is 100% plastic-free. It's compatible with a wide range of USB-C devices: laptops (MacBook Pro, Dell XPS, etc.), tablets (iPad Pro, Samsung Galaxy Tab), and smartphones (iPhone 15/16 series, Android flagships).

Connectivity & Compatibility

Both ends of the cable are USB Type-C (male). One end connects to your USB-C PD charger (sold separately), and the other splits into two USB-C plugs for your devices. The cable does not support data transfer — it is strictly for power delivery. To use the full 140W, your charger and laptop must both support USB-C PD 3.1 140W. Smart Power Sharing works with any USB-C PD device: power levels are negotiated automatically. For dual-device charging, the total output is capped at 140W split between the two ports, so expect lower per-device speed when both are connected. Compatibility is broad: any USB-C device that accepts PD is supported. However, devices that require proprietary charging (e.g., some gaming laptops with barrel plugs) won't benefit. Always use a certified 140W+ PD charger for best results.

Product Info

Released around 2025, the Belkin BoostCharge Pro Dual USB-C Cable sits in the mid-to-premium tier of charging accessories. Its key selling points are high power capacity (140W) and the convenience of dual-device charging in a single braided cable. The retail price in Japan is approximately ¥2,390 (tax included), which is competitive for a 140W dual USB-C cable with this build quality. The cable comes with a 2-year limited warranty and is available from Japan and Belkin's official store. Environmentally conscious buyers will appreciate the recycled braiding and plastic-free packaging.

Best Use Cases

Frequent travelers with a high-wattage laptop and a smartphone: One cable charges both a 140W-capable MacBook Pro and an iPhone from a single charger, cutting down on cable clutter. Best for users staying in hotels or coworking spaces. Not ideal if you need ultra-fast charging for both devices simultaneously (power is shared). Remote workers or minimalists at their desk: Reduces desk cable mess by eliminating the second charging cable. The 1.5m length is perfect for typical desk setups. Suitable for anyone with two USB-C gadgets who hates tangled wires. A downside: you still need a separate power adapter with at least 140W output. * Tech enthusiasts with multiple USB-C portable devices: Charging a tablet, phone, and wireless earbuds case? This cable handles two at a time with smart power distribution. Not recommended if you also require data syncing — this cable is power-only. Also, if you charge only one device at a time, a standard single USB-C cable is simpler and often cheaper.
