This article covers 【10Gbps高速転送】ORICO USB3.1ハブ Gen2 4ポート USBハブ 12V2A 電源アダプター付き 1mUSBケーブル付 OTG機能対応 高放熱 アルミ M3H4-G2.

Overview

The ORICO M3H4-G2 is a 4-port USB 3.1 Gen2 hub that delivers up to 10Gbps transfer speeds. It comes with a 12V/2A external power adapter, ensuring stable power delivery even when connecting multiple external drives or power-hungry devices. The aluminum alloy housing provides excellent heat dissipation, and the 32-degree angled design makes plugging and unplugging cables more convenient on a cluttered desk.

Connectivity & Compatibility

This hub features four USB Type-A ports, all supporting USB 3.1 Gen2 (10Gbps) and backward compatible with USB 3.0/2.0/1.1. It works plug-and-play with Windows, macOS, and Linux without additional drivers. OTG functionality is supported, allowing connection to compatible smartphones and tablets for use with USB flash drives, mice, or keyboards. Note that the external power adapter is mandatory — the hub does not operate on bus power alone.

Product Info

Released around 2020, the ORICO M3H4-G2 sits in the mid-range USB hub segment. It typically retails for around ¥4,000 (approx. $30 USD), offering excellent value for a 10Gbps 4-port hub with a bundled power adapter. The package includes a 1-meter USB 3.0 cable, a 12V/2A power adapter, and a user manual. ORICO provides a 12-month warranty and lifetime technical support. The hub is widely available on and through major electronics retailers.

Best Use Cases

Users who frequently connect external SSDs/HDDs: The 10Gbps speed and stable power supply make file transfers and backups smooth. Even 3.5-inch desktop drives that often struggle with bus power will work reliably. Desktop users needing more USB ports: If your PC's built-in ports are insufficient, this hub adds four high-speed ports. The angled design and aluminum build look great on any desk and make cable management easier. * Mobile users leveraging OTG: Connect the hub to a compatible smartphone or tablet to use USB peripherals. However, because the hub requires external power, you'll need a portable power source when on the go. This hub is less suitable for those who need a bus-powered, ultra-portable hub or exclusively USB-C connections — in those cases, consider a compact USB-C hub instead.
