This article covers Cable Matters コンボパック 40Gbps ライトアングル USB C アダプターキット.
Overview
The Cable Matters Combo Pack 40Gbps Right-Angle USB-C Adapter Kit is a two-pack set designed to tidy up USB-C cable routing in tight spaces. It includes one up/down 90-degree adapter and one left/right 90-degree adapter, giving you four possible orientations to match any device port layout. Whether you are using a laptop, smartphone, tablet, or handheld gaming console, these adapters let you reroute the cable along the device body rather than sticking straight out.
Each adapter supports USB4, Thunderbolt 3, and Thunderbolt 4 at full 40Gbps bandwidth, along with up to 240W USB Power Delivery charging and DisplayPort Alt Mode video output up to 4K@240Hz or 8K@60Hz. The aluminum housing and gold-plated connectors ensure reliable contact and long-term durability, making this kit a practical addition to any USB-C setup.
Connectivity & Compatibility
This adapter kit converts a USB-C male plug into a USB-C female receptacle at a 90-degree angle. It is fully compatible with USB4, Thunderbolt 3, and Thunderbolt 4 standards, maintaining the full 40Gbps data rate. Power Delivery up to 240W passes through without restrictions, so you can use high-wattage chargers and still get rapid charging. Video output via DisplayPort Alt Mode supports 4K at 240Hz and 8K at 60Hz, making it suitable for external monitors and projectors.
- Supported devices: Any USB-C-equipped laptop (MacBook, Windows ultrabooks), smartphone (iPhone 16/17, Android), tablet, handheld console (Steam Deck, Nintendo Switch), external SSD, docking station, and more.
- Orientation: Choose the up/down adapter when the port is on the top or bottom edge; use the left/right adapter for side-mounted ports.
- Important: Because the adapter physically changes the cable exit direction, you should verify that the chosen orientation clears nearby obstacles (case edges, desk walls, adjacent cables) before finalizing your setup.
Product Info
The Cable Matters 40Gbps Right-Angle USB-C Adapter Kit was released in 2023 and is sold primarily through online retailers. The two-pack is priced around ¥3,500, offering excellent value compared to single-adapter alternatives. Warranty coverage is provided by Cable Matters (typically 1–2 years), but you should check the latest terms on the brand's official support page. Only the two adapters are included in the box; no cables or manuals are bundled.
Market positioning falls in the mid-range segment: it delivers full Thunderbolt 4 / USB4 throughput and high-wattage PD support, yet costs less than many single 40Gbps adapters from other brands. For users who need reliable, high-speed USB-C connectivity without paying a premium, this kit is a smart pick.
Best Use Cases
- Desktop organization: If you are tired of USB-C cables protruding awkwardly from the side or back of your laptop, these right-angle adapters let you run the cable flush against the desk or wall. Setup becomes cleaner, and accidental cable snags are less likely. However, if your desk layout has unusual angles or very tight tolerances, verify that the adapter's orientation works with your specific cable and port position.
- Mobile charging comfort: When using your phone or tablet while it charges, a straight cable can dig into your hand or get in the way. Attaching a right-angle adapter redirects the cable behind or beside the device, making one-handed operation much more comfortable. Since the adapters support 240W PD, they work flawlessly with the latest fast chargers and power banks. Just be careful not to bend the cable sharply right after the adapter, as that can strain the connector.
- Handheld gaming setups: Steam Deck owners often complain that the top-mounted USB-C port forces the charging cable to stick out, making the device unstable when placed on a table. A 90-degree adapter allows the cable to exit toward the back, keeping the unit flat and stable. The same benefit applies to Nintendo Switch, Ayaneo, and similar handhelds. Note that thicker protective cases may block the adapter's insertion, so test the fit before relying on it daily.
