3-Port USB 3.0 Hub

The UGREEN 20265 expands one USB-A connection into three additional USB-A 3.0 ports.

USB Specifications

• Host Connector: USB-A Male
• USB Outputs: 3 × USB-A Female
• USB Standard: USB 3.0 / USB 3.2 Gen 1
• Maximum Theoretical Speed: 5Gbps
• USB 2.0 Compatibility: Yes
• USB 1.1 Compatibility: Yes

Compatible peripherals include:

• External SSDs
• External HDDs
• USB flash drives
• Keyboards
• Mice
• Webcams
• USB headsets
• Speakers
• Printers
• Controllers
• Other USB-A accessories

The three USB ports and Ethernet interface share the bandwidth available from the single upstream USB 3.0 connection.

Gigabit Ethernet – Up to 1000Mbps

The built-in RJ45 port adds wired Ethernet connectivity to compatible computers.

Network Specifications

• Ethernet Port: RJ45
• 10Mbps: Yes
• 100Mbps: Yes
• 1000Mbps / Gigabit: Yes
• Maximum Link Rate: 1Gbps
• IEEE 802.3: Yes
• IEEE 802.3u: Yes
• IEEE 802.3ab: Yes

A wired Ethernet connection can be particularly useful for online gaming, video calls, large file transfers, streaming, and situations where Wi-Fi is weak or congested.

Actual internet speed still depends on your internet plan, router/switch, Ethernet cable, network traffic, and host computer.

Ideal for Laptops Without Ethernet

The UGREEN 20265 is useful for laptops and computers that have USB-A but lack an integrated Ethernet port.

Example:

Laptop USB-A → UGREEN 20265 → Gigabit Ethernet + Keyboard + Mouse + External Drive

This provides networking and peripheral expansion through one USB connection.

Nintendo Switch Compatibility

The adapter supports wired Ethernet connectivity with compatible Nintendo Switch / Switch OLED setups. UGREEN notes that Switch functionality is limited to the Ethernet function rather than general use of all three USB hub ports.

It can therefore provide a wired network option for compatible Nintendo Switch dock configurations.

Up to 5Gbps USB Data Transfer

The USB 3.0 interface supports theoretical transfer speeds up to 5Gbps, approximately ten times the signaling rate of USB 2.0's 480Mbps.

This makes the hub suitable for high-speed file transfers with compatible storage devices.

USB Speed Comparison

Actual transfer performance depends on the connected device, storage media, host USB interface, and simultaneous activity on the hub.

Auxiliary DC Power Input

The UGREEN 20265 includes a DC 5V auxiliary power input for situations where connected USB peripherals require more power than the host USB port can reliably provide.

UGREEN specifies this primarily for power-demanding accessories such as external hard drives.

Power

• Auxiliary Input: DC
• Voltage: 5V
• Recommended Supply: Up to 5V / 2A
• Purpose: Additional power for USB peripherals
• Laptop Charging: No
• Power Adapter: Not included

The DC input should not be confused with USB-C Power Delivery. It does not charge the connected laptop.

Compatibility

The UGREEN 20265 supports compatible versions of:

• Windows
• macOS
• ChromeOS
• Linux
• Microsoft Surface devices
• MacBook Air models with USB-A
• MacBook Pro models with USB-A
• iMac / iMac Pro
• Chromebooks with USB-A
• Desktop PCs
• Laptops
• Nintendo Switch / Switch OLED via compatible setup

Driver requirements vary by operating-system version. Modern Windows and ChromeOS versions generally offer straightforward recognition, while some older Windows, macOS, or Linux versions may require a compatible Ethernet driver.

Port Summary

Important Note

This model uses a USB-A host connector, not USB-C. A modern laptop with only USB-C ports would require a suitable USB-C-to-USB-A adapter or a different USB-C Ethernet hub.

The adapter also does not include HDMI/display output or USB-C Power Delivery. Its main purpose is:

1 USB-A Port → 3 USB-A 3.0 Ports + Gigabit Ethernet

Best For

• Windows Laptops
• Desktop PCs
• Surface Pro
• MacBook Air with USB-A
• iMac / iMac Pro
• Chromebooks
• Nintendo Switch / Switch OLED Ethernet
• External HDDs & SSDs
• USB Flash Drives
• Keyboards & Mice
• Webcams
• Office Workstations
• Wired Internet
