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 104 x 30 x 10 mm, 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.
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.
The UGREEN 4-port USB 3.0 hub was first listed around 2023 and is available on for approximately ¥2,271 (tax included). It comes with a standard one-year manufacturer warranty; returns can be handled through . The package includes only the hub itself — no USB-C power cable or charger is provided. Positioned as an entry-level to mid-range accessory, this hub focuses on reliable USB 3.0 expansion with the added flexibility of an external power option. Its silver-gray finish blends with most desk setups, making it a practical choice for both home and office use.

  • Laptop users: MacBook, Surface Pro, or any ultrabook with limited ports can instantly add four USB-A ports for flash drives, wireless mice, and external SSDs. The compact size makes it easy to slip into a laptop bag. - Console gamers: Connect PS5 or PS4 controllers for charging, or attach an external USB drive for game storage. The hub is recognized without extra drivers, keeping your console area tidy. - Travelers and remote workers: When working from a café or a meeting room, this hub lets you plug in multiple peripherals without hunting for a power outlet. The bus-power mode works fine for most low-power devices, and the self-powered option is there when you need it.
