UGREEN US129 90722 5 m USB 3.0 Extension Cable

Overview

The UGREEN US129 (90722) adds 5 m to a USB-A connection, so a device can sit where it is needed rather than next to the computer. It is a passive USB 3.0 extension, a USB-A plug at one end and a USB-A socket at the other, rated for up to 5 Gbps when every link in the chain supports it.

Is it right for you?

• Suits keyboards, mice, printers, scanners, controllers and wireless receivers with standard USB-A connections.
• USB storage and webcams work only when the full 5 m passive route stays stable under load; a powered hub or an active extension is safer for them.
• A computer with only USB-C ports needs a separate data-capable adapter or hub; the cable has no USB-C plug.
• It is passive: it does not regenerate the signal like an active extension, and it does not add power.

Key features

• 5 m of extra reach for one USB-A connection.
• USB 3.0 data up to 5 Gbps theoretical, and USB 2.0 and 1.x devices run at their own speeds.
• Passes ordinary USB power from the host within practical voltage and current limits.
• Gold-plated contacts and shielded cable construction.
• No driver needed; it is a physical extension.
• One female socket, so it does not split the connection.

What else you need

A computer, recorder or hub with a USB-A port and a USB-A peripheral. For hard drives, webcams or anything that draws real power, plan a powered hub.

Before you buy

• The 5 Gbps figure is theoretical. The host controller, device speed, workload and the 5 m passive run reduce real throughput.
• Power pass-through does not guarantee that full voltage reaches the device, so a hard drive, webcam or charging device may not run reliably.
• A hub shares bandwidth and adds a cable segment: use a powered model and test everything that will run at once.
• Webcams and capture devices may drop frames before a file transfer shows a fault. Eject storage properly and keep backups.
• Do not daisy-chain several extensions. Indoor use; keep connectors dry and free of debris.
