This article covers バッファロー BUFFALO USB ハブ PS5 iMac MacBook Air.

Overview

The BUFFALO BSH4U125C1BK is a compact 4-port USB hub that lets you connect your existing USB Type-A devices to any USB Type-C host, including Windows PCs, Macs, Chromebooks, and game consoles like the PS5. It supports USB 3.2 (Gen 1), 3.1 (Gen 1), and 3.0 standards, delivering transfer speeds up to 5Gbps. Its slim, lightweight design makes it ideal for travel or tidying up a home-office desk. This package contains three units, making it a cost-effective choice for multiple workstations, family sharing, or small-office setups. The hub is bus-powered, so no external AC adapter is required — just plug it into a Type-C port and you're ready to go. With three ports on the front and one on the side, cable management stays clean even with several devices connected.

Best Use Cases

Remote workers / home-office users: If your laptop has only one or two USB ports, this hub lets you connect a mouse, keyboard, webcam, and flash drive simultaneously. The slim profile keeps your desk clutter-free. Gamers (PS5/PC): Expand the PS5's front USB ports for charging controllers or connecting external storage. Just be aware that bus power may not support high-capacity HDDs for extended use. MacBook users: MacBook Air/Pro owners with only Type-C ports can use this hub to connect legacy USB-A peripherals like printers, memory sticks, and wired mice without needing a separate dongle. Not recommended for: Users who need to run multiple power-hungry devices (e.g., portable SSDs, external HDDs) simultaneously. In that case, choose a self-powered hub with an AC adapter.

Things to Consider

Because this hub is bus-powered, the total current draw of connected devices must stay within the host port's capability (typically 5V/0.5A–0.9A). Connecting multiple high-power devices may cause intermittent disconnections or failure to recognize devices. If you plan to use portable HDDs or charge multiple gadgets at once, invest in a self-powered hub. Also note that this hub does not support Thunderbolt 3/4 or USB4 features such as 40Gbps transfer or DisplayPort Alt Mode. It is strictly a USB 3.1 Gen 1 (5Gbps) data hub for USB-A devices. The 3-pack is economical if you need hubs for multiple locations, but a single-pack version (BSH4U125C1B) is also available if you only need one. Check your actual requirements before purchasing.
