This article covers UGREEN USB 3.0 ハブ ４ポート拡張 USB ハブ USB C電源供給 セルフパワー.

Overview

If your laptop or desktop suffers from a shortage of USB ports, the UGREEN USB 3.0 4-Port Hub (model 4A-150CM) offers a compact and affordable solution. Measuring just 10.4 x 3 x 1 cm, this hub expands a single USB-A port into four USB 3.0 ports, each supporting data transfer speeds up to 5 Gbit/s — about ten times faster than USB 2.0. A key differentiator is the USB-C power input on the side. In bus-power mode, the hub runs directly from your computer's USB port. But when you need to connect high-power devices like external hard drives, you can plug in a separate USB-C charger (not included) to switch to self-powered mode, ensuring stable operation even with all four ports occupied. The hub is compatible with Windows, macOS, Linux, and game consoles such as PS5 and PS4.

Connectivity & Compatibility

The hub supports USB 3.0 (backward compatible with USB 2.0 and 1.1) and works plug-and-play with Windows 10/8.1/8/7/Vista/XP, macOS X 10.6–10.9, Linux 2.6.14+, PS4, PS5, Xbox One, MacBook, Surface Pro, MateBook X Pro, and many other devices with a standard USB-A port. A small LED on the front indicates power/activity status. For self-powered operation, connect a USB-C cable and a 5V/2A (or higher) USB charger (both sold separately) to the hub's USB-C port. This guarantees stable power delivery for four downstream devices simultaneously, eliminating the risk of dropouts or slow charging when using bus power alone.
