This article covers Cable Matters 40Gbps Thunderbolt 4ケーブル 0.3m.

Overview

The Cable Matters 40Gbps Thunderbolt 4 Cable (0.3m) is an Intel-certified USB-C cable designed for users who demand the highest data transfer speeds and charging capabilities. With support for up to 40Gbps data transfers and Power Delivery 3.1 delivering up to 240W, this cable is a versatile tool for modern laptops, tablets, and peripherals. Its short 0.3m length makes it ideal for tidy desk setups, connecting a laptop to a dock or monitor without excess cable clutter. It also supports 8K@60Hz video output and is backward compatible with Thunderbolt 3, USB4, and USB-C 3.2 devices.

Connectivity & Compatibility

This cable uses a USB-C connector and is compatible with any device featuring a Thunderbolt 4 port, including MacBook Pro, MacBook Air, Windows laptops, Thunderbolt 4 docks, external SSDs, and monitors. Full backward compatibility with Thunderbolt 3 ports, maintaining 40Gbps speeds on Thunderbolt 3 devices. Works with USB4, USB-C 3.2 Gen 2 (10Gbps), USB 3.1, and USB 2.0 devices, ensuring broad compatibility. Supports DisplayPort Alt Mode for video output up to 8K@60Hz or dual 4K@60Hz displays. Provides up to 15W of power delivery to bus-powered devices.

Product Info

The Cable Matters 40Gbps Thunderbolt 4 Cable 0.3m is available on for around ¥2,599. It carries Intel certification, guaranteeing full Thunderbolt 4 functionality: 40Gbps data transfer, 240W charging, and 8K video output. Positioned in the high-end market segment, this cable commands a premium over standard USB-C cables but delivers significantly higher performance in data speed and charging power, making it a favorite among creative professionals and power users. Warranty coverage is standard (typically 1-2 years from the manufacturer). The package includes only the cable itself, with no additional accessories.

Best Use Cases

MacBook Pro / Air users: Perfectly matched with Thunderbolt 4-equipped Macs. The 240W charging capability supports even large-battery models like the MacBook Pro 16-inch for rapid top-ups. Users with external SSDs or docks: The 40Gbps transfer speed dramatically reduces file transfer and backup times. Pair it with a Thunderbolt 4 dock for an efficient, clutter-free desk setup. * Users building 8K or dual 4K monitor setups: A single cable handles 8K@60Hz video, ideal for high-end multi-monitor configurations. If your needs are limited to smartphone charging or basic data sync, a cheaper USB-C cable will suffice. Also, the 0.3m length is too short for connecting devices placed far apart.

Things to Consider

The 0.3m length is extremely short, making it suitable only for close-proximity connections on a desk. For setups where the monitor and laptop are separated by a distance, consider a 1m or 2m cable. To achieve 240W charging, both the charger and the device must support Power Delivery 3.1 (240W). A standard 100W charger will not deliver the full 240W benefit. Full Thunderbolt 4 performance (40Gbps, 8K output) requires both the host and device to support Thunderbolt 4. When connected to a plain USB-C port, speeds will be limited to USB 3.2 Gen 2 (10Gbps) or lower. Competitors include Anker and Belkin Thunderbolt 4 cables. Cable Matters offers a more budget-friendly option with strong value for the price.
