This article covers Satechi 8 in 1 USB C ハブ マルチポートアダプター V3.

Overview

The Satechi 8-in-1 USB-C Hub Multiport Adapter V3 is a compact dock that transforms a single USB-C port into a full workstation. It supports up to 8K resolution at 30Hz via HDMI, along with high refresh rates like 4K@120Hz and 1080p@240Hz, making it suitable for gamers, creatives, and professionals. The built-in 100W Power Delivery pass-through lets you charge your laptop while using all ports, eliminating the need for a separate charger. This hub packs eight ports into a slim aluminum chassis that matches the aesthetic of MacBooks. It includes four USB data ports, gigabit Ethernet, an SD card reader, and an HDMI output. Whether you're connecting multiple peripherals, transferring files, or driving an external display, this adapter handles it all in one tidy package.

Connectivity & Compatibility

The hub is compatible with any USB-C host device, including MacBook Pro/Air (M5/M4/M3/M2/M1), MacBook Neo, iPad Pro/Air, Windows laptops, and Samsung Galaxy DeX mode. It works with Thunderbolt 3, Thunderbolt 4, and USB4 ports. However, note that Intel-based Macs and some M1–M3 MacBooks may limit HDMI output to 4K@60Hz due to host restrictions. Port breakdown: HDMI 2.1 (up to 8K@30Hz, 4K@120Hz, 1440p@144Hz, 1080p@240Hz) USB-C PD port (100W input, 85W host charging) 3× USB-C (USB 3.2 Gen2, 10Gbps) 1× USB-A (USB 3.2 Gen2, 5Gbps) Gigabit Ethernet (RJ-45) MicroSD / SD card slot (UHS-II, up to 312MB/s)

Product Info

Released around 2025, the Satechi 8-in-1 USB-C Hub V3 is positioned as a premium accessory for Mac users and anyone needing high-resolution video output. Its 8K support and 100W PD pass-through are standout features in the mid-to-high-end hub market. The hub is available on Japan for approximately ¥14,799, backed by a 2-year limited warranty. The package includes the hub and a user manual. The attached cable is roughly 20 cm long, making it ideal for desk setups without excessive cable clutter. The aluminum construction feels premium and dissipates heat well during extended use.

Best Use Cases

MacBook owners (especially M5/M4 series): This hub is a perfect match for modern MacBooks, offering a single-cable solution for charging, display, and peripherals. The 8K output future-proofs your setup for high-resolution monitors. However, users who need Thunderbolt 4 speeds (40Gbps) should look for a dedicated Thunderbolt dock. Content creators and photographers: The UHS-II SD card reader and fast USB-C ports enable quick media transfers from cameras and external SSDs. The HDMI port can drive a high-refresh-rate 4K monitor for smooth video editing. Be aware that simultaneous high-bandwidth operations may throttle performance due to USB-C bandwidth sharing. * Remote workers and travelers: With built-in Ethernet and HDMI, you can connect to hotel networks and conference room displays without extra dongles. The compact size fits easily into a laptop bag. However, the Ethernet port is limited to 1Gbps, which may not suffice for very fast office networks or large file transfers over LAN.
