This article covers 【限定】 Belkin 8-in-1 USBハブ 4Kデュアルディスプレイ対応 1Gbpsイーサネット 10Gbpsデータ転送 100W PD対応 SiliconMotion対応 MacBook M1.

Overview

Belkin’s 8-in-1 USB Hub (model INC015btSGY-CZ-A) is a compact solution for anyone who needs to expand a laptop’s connectivity without sacrificing desk space. Its headline feature is the Silicon Motion chipset, which lets M1/M2/M3 MacBooks drive two external 4K monitors — something Apple’s own hardware normally prohibits. One HDMI port outputs at 4K/60Hz, the other at 4K/30Hz, giving you a dual-display setup that’s great for productivity. The hub also delivers 100W Power Delivery pass‑through, so your notebook stays charged through a single USB‑C link. Despite its small footprint (14.8 x 6.8 x 1.9 cm, 295 g), the hub packs two USB‑C 10Gbps ports, two USB‑A 5Gbps ports, a 1Gbps Ethernet jack, and two HDMI outputs. The integrated 22cm cable keeps the unit tethered to your laptop, reducing clutter. This exclusive also comes with a wallpaper download as a bonus.

Connectivity & Compatibility

Supported devices: MacBook Air/Pro (M1/M2/M3), Windows laptops, Chromebooks Video: 2× HDMI — first supports 4K/60Hz, second 4K/30Hz Data: 2× USB‑C (10 Gbps), 2× USB‑A (5 Gbps) Network: 1 Gbps Ethernet (RJ‑45) Power: USB‑C PD input up to 100W (pass‑through to host) Note: The Silicon Motion dual‑monitor feature may require driver installation on some operating systems; drivers are available from the Silicon Motion website. On MacBooks, the hub bypasses the native single‑display limit.

Product Info

The hub launched in 2025 as an exclusive, priced around ¥14,900 at the time of writing. Belkin backs it with a two‑year warranty. In the box you get the hub itself (with attached 22cm USB‑C cable), a quick‑start guide, and a download code for exclusive wallpapers. Market positioning sits in the upper‑mid tier: it competes with premium hubs like the Anker PowerExpand or CalDigit TS3, but stands out with its integrated Silicon Motion chip that solves the MacBook single‑monitor limitation. Because it’s an ‑only SKU, availability elsewhere is limited.

Best Use Cases

MacBook users who need two external monitors: If you run Xcode, Final Cut Pro, or any multi‑window workflow, this hub turns your MacBook into a true desktop replacement. The Silicon Motion chip does the heavy lifting; just install the driver and you’re set. Not ideal for users who prefer wireless everything and don’t need a dock at all. Remote workers and gamers needing wired Ethernet: The 1Gbps port ensures stable, low‑latency connections for video calls, large file transfers, or online gaming. If you’re already on a fast Wi‑Fi network, the Ethernet port may be redundant. Travelers with compact setups: The hub’s 22cm cable and small weight make it easy to slip into a laptop bag. But if your laptop’s USB‑C port is on the opposite side, the short cable might be awkward — plan your desk layout or use a short extension. Users who want everything in one cable: With 100W PD, you only need one wall charger for both the laptop and the hub. Be aware that the second HDMI is limited to 4K/30Hz, so if you need dual 4K60, this isn’t the right pick.

Things to Consider

Driver dependency: The dual‑monitor magic relies on a Silicon Motion driver. While it works out of the box on many systems, some Linux or older macOS versions may require manual installation. Always check the official support page before buying. HDMI 2nd port limitation: The second HDMI runs at 4K/30Hz. If you need two monitors at 60Hz, consider a hub with Thunderbolt or DisplayLink that can deliver two full‑speed ports. Short integrated cable: At 22cm, the cable is designed for tight pairing with the laptop. If you need more reach, you’ll have to add a USB‑C extension cable (which may affect PD efficiency). exclusivity: Since this SKU is limited to , international buyers may face higher shipping costs or import duties. Price fluctuations are common, so watch for deals.
