This article covers StarTech 4ポートセルフパワーUSB Cハブ 個別オン.

Overview

The StarTech ST4300USBC is a self-powered 4-port USB-C hub that adds four USB-A ports to your computer. Each port features an individual on/off switch with LED indicator, allowing you to control power to connected devices independently. It supports USB 3.0 (5Gbps) data transfer and comes with a 36W power adapter for reliable operation. The included combo cable works with both USB-C and USB-A hosts, making it versatile for desktops and laptops.

Connectivity & Compatibility

This hub supports both USB-C and USB-A host connections via the included 1-meter 2-in-1 cable. It is compatible with Windows, macOS, Linux, iPadOS, Chrome OS, and Android without driver installation. Thunderbolt 3/4 ports are also supported. Each port provides BC 1.2 charging at up to 1.5A (7.5W), with a total of 30W across all ports. The hub can charge devices even when the host computer is disconnected (dedicated charging port mode). It works with USB 2.0/1.1 peripherals as well.

Product Info

Released around 2022, the ST4300USBC is priced around ¥20,000–¥22,000. It comes with a 2-year warranty (extendable upon registration). The package includes the hub, 36W power adapter, combo USB-C/USB-A cable, and quick-start guide. Market positioning is mid-range; few competing hubs offer individual port switches with self-powered design, making it a solid choice for both professional and home use.

Best Use Cases

  1. Desktop PC users: Easily add four USB-A ports to the front of your desk, avoiding the hassle of reaching the back panel. Individual switches let you turn off unused devices to save power. Not ideal if you need additional USB-C ports. 2. Laptop users: Expand a single USB-C port into four USB-A ports, perfect for connecting multiple peripherals like external drives, mice, and keyboards. Note that it does not support USB-C Power Delivery pass-through, so you'll need a separate charger for your laptop. 3. Privacy-conscious users: Physically disconnect webcams, microphones, or other sensitive devices using the hardware switches, providing a reliable privacy measure beyond software controls. Not suitable for users requiring USB 3.1 Gen2 (10Gbps) speeds.
