UGREEN US129 90722 5m USB 3.0 Extension Cable
Overview
UGREEN 90722 extends one USB-A host port to one female USB-A socket. The blue USB 3.0 contact inserts identify the SuperSpeed-capable format, but the complete route runs only as fast as its slowest host port, cable segment, hub and peripheral.
What it does well.

Key features
Highlights
- format: 5m USB-A 3.0 male to USB-A 3.0 female extension.
- Data rating: up to 5Gbps theoretical with a complete SuperSpeed-compatible chain.
- Passive construction: no repeater, hub chipset or external power connector.
- Backward compatibility: USB 2.0 and 1.x devices can operate at their lower supported speeds.
- Contact and shielding detail: gold-plated contact surfaces and shielded cable construction.
Connector and data-path map
Know the controls and roles
USB host and peripheral roles still apply even though the cable can be physically reversed end-for-end only by changing which connector fits.
- USB-A male: plugs into a real computer, console, hub or other USB host/downstream port.
- USB-A female: receives the peripheral’s USB-A male plug or a short compatible device lead.
- SuperSpeed contacts: need USB 3.x support across the entire route to negotiate above USB 2.0.
- Data flow: bidirectional USB communication between host and peripheral.
- Power flow: conventional USB bus power from the host; no USB-C PD negotiation or auxiliary power input.
- Signal conditioning: none—the 5m cable is passive.
Use scenarios
Where it makes sense
The cable is best for USB-A peripherals that are proven stable at 5m and whose power demand fits the host path.
- Move a keyboard, mouse, receiver or game controller to a more convenient desk or presentation position.
- Reach a printer, scanner or document device whose own power supply handles its main load.
- Place a USB flash drive or externally powered storage dock where it is accessible, then test sustained transfer before relying on the route.
- Extend a compatible webcam only after verifying stable video at the intended resolution and frame rate.
- Connect a powered USB hub where multiple peripherals must be located remotely and the host topology supports it.
- Route a USB-A accessory to a television or console only when that host officially supports the peripheral.
Setup and usability guidance
A dependable first connection
Prove the same device works directly first, then add the extension and test the highest-load task.
- Confirm USB-A connector fit and whether the required speed is USB 3.x or only USB 2.0.
- Test the peripheral directly on the selected host port and install any required driver or application.
- Insert the extension male plug fully, connect the peripheral at the female socket and avoid extra extension segments.
- Check the operating system’s negotiated connection and run a sustained transfer, video stream or actual device workload.
- If a bus-powered device disconnects, try a shorter cable, a different host port or a supported externally powered hub.
- Eject storage and close camera/audio applications before disconnecting.
- Route with broad bends and strain relief; do not stretch the cable between furniture or across a walkway.
Compatible devices and systems
Match the whole chain
Compatibility requires correct USB roles, enough signal margin, adequate power and a supported peripheral driver.
- USB-A desktop and notebook host ports with USB 3.x or earlier support.
- Keyboards, mice, printers, scanners, controllers and receivers with standard USB-A connections.
- USB storage and webcams when the complete 5m passive route remains stable under load.
- Powered hubs and powered peripherals that follow normal USB topology.
- USB 2.0 or 1.x devices at their own lower data rate.
- USB-C-only hosts through a separate data-capable adapter or hub; no direct USB-C plug is present.
What this product does
Capabilities
- Adds 5m of physical reach to one USB-A connection.
- Carries SuperSpeed USB data up to 5Gbps theoretical when every link supports it.
- Passes conventional USB power from the host within practical voltage and current limits.
- Supports lower-speed USB devices at their negotiated rate.
- Works without a dedicated cable driver because it is a passive physical extension.
- Provides one female endpoint and does not split the connection.
What this product does not do
Clear boundaries
- It does not regenerate the signal like an active extension cable.
- It does not add an externally powered hub or guarantee adequate power for a hard drive, webcam or charging device.
- It does not provide USB-C Power Delivery, Quick Charge, HDMI, Ethernet or video conversion.
- It does not increase a USB 2.0 device or port to USB 3.x speed.
- It does not create host mode on a television, phone or peripheral-only port.
- It does not make daisy-chained long extensions a supported topology.
What to do
Good practice
- Use a direct host connection and the fewest possible cable segments.
- Test sustained data and full peripheral operation, not only enumeration or an indicator light.
- Use a supported powered hub for several peripherals or high bus-power demand.
- Eject storage before unplugging and keep backups of important data.
- Coil loosely for storage and keep connectors capped or clean when possible.
- Support the female coupling so the attached device cable does not hang from a desk edge.
What not to do
Avoid these mistakes
- Do not call the cable active or expect it to correct signal loss electronically.
- Do not use it for USB-C laptop charging or as a fast-charge converter.
- Do not daisy-chain several 5m passive extensions and assume SuperSpeed operation.
- Do not pull by the connector, crush the jacket, make tight bends or route it where chairs roll over it.
- Do not connect two computers together; this is not a host-to-host transfer bridge.
- Do not continue using a loose, hot, cut or intermittent cable around valuable storage.
Warnings and limitations
Important safety and performance notes
A low-power mouse can work where a fast bus-powered drive or high-resolution camera does not; device category matters.
- The 5Gbps figure is theoretical. Encoding, host controller, device speed, file workload and the passive 5m run reduce real throughput.
- Conventional power pass-through does not guarantee the listed current reaches the device at full voltage.
- A hub shares bandwidth and may add another cable segment; use a powered model and test all simultaneous workloads.
- Webcams and real-time capture devices may show dropped frames before an ordinary file transfer appears faulty.
- Protect storage from unexpected disconnects by ejecting it and keeping current backups.
- The cable is for indoor electronics use unless an installation standard explicitly says otherwise; keep connectors dry and free of debris.
Care, troubleshooting and buying checklist
Keep it working and solve common issues
Compare direct connection, extended connection and a known-good host port.
- No device: test direct, reseat both ends, remove adapters/hubs and confirm the host port is functional.
- Runs only at USB 2.0: one part of the chain may lack SuperSpeed contacts or the long route may not negotiate reliably.
- Storage disconnects: reduce cable length or use a separately powered device/hub supported by the storage maker.
- Webcam freezes: lower resolution temporarily, close competing USB streams and test another host controller.
- Slow copy: compare the same file and device directly; flash media speed and small-file workload can dominate results.
- Intermittent when touched: inspect plug fit and strain relief, then replace the cable if movement breaks the link.
- Buying check: select US129 90722 for a passive 5m USB-A SuperSpeed route; choose an active or powered design when the device demands it.
