This article covers SATECHI USB-C クランプ式ハブ iMac M4用.

Overview

The SATECHI USB-C Clamp Hub is a purpose-built accessory for the 24-inch iMac M4, M3, and M1 models. It attaches securely to the underside of the iMac using an adjustable clamp, bringing essential ports to the front for easy access. The hub features a USB-C data port (up to 5Gbps), three USB-A 3.0 ports (each up to 5Gbps), and MicroSD/SD card reader slots. Its silver aluminum finish seamlessly matches the iMac’s design, maintaining a clean and professional desktop appearance. Plug-and-play setup means no drivers or additional tools are required—just connect the hub to the iMac’s rear USB-C port and start using it immediately.

Connectivity & Compatibility

The hub connects to the iMac via a single USB-C cable that plugs into the rear USB-C port. It is compatible with the 24-inch iMac models powered by M4, M3, and M1 chips, as well as the Apple Studio Display. Important: The hub does not work with iMac models from 2020 or earlier. The front-facing ports include one USB-C (data only, 5Gbps), three USB-A 3.0 (5Gbps each), a MicroSD slot, and an SD slot. Note that these ports are for data transfer and card reading only—they cannot charge phones or power devices like the Apple SuperDrive. Because the hub is bus-powered, the total power available for connected peripherals is limited, so high-power devices may not function reliably.
