This article covers Cable Matters USBCオス. The Cable Matters USB-C Male to Dual USB-A Female Splitter Cable (30cm) is a compact Y-splitter that turns a single USB-C port into two USB-A ports.

It supports data transfer up to 480Mbps (USB 2.0) and BC 1.2 charging at up to 1.5A per port.

This cable is ideal for users who need to connect legacy USB-A peripherals to modern USB-C laptops, tablets, or smartphones without carrying a full hub. At just 30cm in length, it's highly portable and easy to stash in a laptop bag.

While it won't satisfy high-speed storage needs, it excels at connecting mice, keyboards, flash drives, and other low-bandwidth devices simultaneously. The cable features a USB-C male connector that splits into two USB-A female ports.

It works with any device that has a USB-C port: laptops (MacBook, Windows ultrabooks), tablets (iPad Pro, Android tablets), and smartphones (USB-C models). Legacy USB-A peripherals connect directly without adapters.

Note that the cable is limited to USB 2.0 speeds (480Mbps), so it's not suitable for external SSDs or high-resolution webcams.

For charging, the host device must be able to deliver sufficient power; otherwise, charging may be slower than expected. Check the retailer's page for the latest price.

It comes with a standard one-year warranty and includes only the cable itself — no drivers or software needed. This is an entry-level product focused on simplicity and affordability.

It's a cost-effective way to add two USB-A ports to a USB-C-only device without investing in a multi-port hub. Laptop users with legacy peripherals: If your laptop only has USB-C ports and you need to connect a USB-A mouse and keyboard simultaneously, this cable is a quick fix.

It's cheaper and less bulky than a hub. Travelers and remote workers: The short 30cm length makes it easy to pack.

Use it in hotel rooms to connect a flash drive and charge your phone at the same time (provided the host can deliver enough power). * Budget-conscious users: For under ¥1000, you get a functional splitter that handles basic data and charging needs.

It's a great spare to keep in your bag. Not recommended for users who need USB 3.0+ speeds or multiple USB-A ports regularly — in those cases, a powered USB hub or docking station would be a better investment.
