UGREEN 1m USB-C Extension Cable, 100W, 10Gbps, 4K60 (10387)
Overview
This 1 m US353 passive cable extends a USB-C connection with a USB-C male plug and USB-C female socket. It can pass up to 10Gbps USB data, up to 100W (20V/5A) USB Power Delivery and video up to 4K at 60Hz—but only when the host, downstream cable or accessory, display and power source all support the requested function. It adds reach; it cannot add a mode missing from the source.

What it does well.
Key features
Passive USB-C extension. The US353 design is passive usb-c extension; that determines signal reach and whether extra electronics are present.
Up to 10Gbps. The listed ceiling applies only when every relevant host, cable segment, adapter and peripheral supports the negotiated USB mode.
1 m reach. Measure the routed path around furniture and leave gentle slack. Do not stretch the cable, pinch it under furniture or make tight bends at either connector.
Power behaviour. PD pass-through up to 100W / 20V 5A with a compatible full chain. PD 2.0 and QC 3.0/2.0 compatibility shown in media; negotiation remains end-to-end.
Use scenarios
Workspace reach. Move a USB-C port into easier reach for a hub, card reader, SSD or peripheral
Peripheral placement. Extend a compatible USB-C charging connection within the documented 100W ceiling
AV or imaging. Connect one compatible USB-C display path when the host provides DisplayPort Alt Mode
Long-route planning. Add 1m to a simple USB-C accessory chain after checking total-length limits
A device category is not a compatibility promise. Confirm its connector, USB mode, driver, power demand and manufacturer guidance for extensions before permanent routing.
Setup and usability guidance
- Test direct first: confirm the peripheral works when connected straight to the host.
- Identify the host end: connect the male plug to the host/source and the female socket to the peripheral side.
- Simplify: remove unnecessary hubs, adapters and other extensions during setup.
- Connect securely: insert straight, support the cable weight and avoid side-load on either port.
- Verify the real task: test sustained transfer, printing, recording, wake/reconnect or display/charging as applicable—not only initial detection.
- Route last: once stable, use broad bends, dry indoor placement and strain relief.
Compatible devices and systems
Suitable for USB-C hosts and devices that use a mutually supported USB data, PD or DisplayPort Alt Mode. Windows, macOS, ChromeOS, iPadOS and other systems need no cable driver, but a dock, display, storage device or adapter may need its own support. Reversible plugs do not make all USB-C ports functionally identical.
Host requirement. A functioning USB-C male host/source port with support for the required USB mode.
Peripheral requirement. A compatible USB-C female connection, suitable device driver and a power demand the complete setup can meet.
Backward modes. Backward operation uses the slowest mutually supported USB mode. A faster-labelled host port cannot raise the capability of a slower cable or device.
No cable driver. The extension itself is plug-and-play. Specialist devices may still need vendor software, permissions, firmware or a particular host controller.
What this product does
- Adds 1 m with USB-C male-to-female connectors.
- Passes compatible USB data up to 10Gbps.
- Passes negotiated USB PD up to 100W / 20V 5A when every component is rated appropriately.
- Passes video up to 4K60 when the source provides DP Alt Mode and the downstream chain supports it.
What this product does not do
- It does not create DisplayPort Alt Mode on a data-only or charging-only USB-C port.
- It does not provide 20Gbps USB 3.2 Gen 2x2, USB4 or 40Gbps Thunderbolt performance.
- It does not guarantee active Thunderbolt 3/4 hubs, complex docks or multi-display chains.
- It is not an active repeater and has no auxiliary-power input.
- It cannot raise charger wattage or bypass the receiving device’s charging limit.
What to do
Match the full chain. Check both connector ends, host capability, peripheral requirements, any downstream lead and the application before installation.
Protect the ports. Support the cable and leave a service loop. Hold the plug housing when disconnecting; do not pull or twist the cable.
Plan peripheral power.
Keep evidence simple. If troubleshooting, change one variable at a time and test direct operation before adding the extension back.
What not to do
Do not join two hosts. Never connect two powered host ports; USB host-to-host wiring can cause damage.
Do not force connectors. USB-A and USB-C are different. Stop if a plug does not align, and never use a loose or damaged socket.
Do not build a cable chain. No supported chain count is published. Extra leads, adapters and hubs reduce signal and power margin.
Do not trust legacy name lists.
Warnings and limitations
Speed: Up to 10Gbps is an interface ceiling, not guaranteed application throughput.
Power: follow the power guidance above; device detection alone does not prove adequate power under load.
Video: Up to 4K60 with source DP Alt Mode and a compatible full chain. Connector shape alone does not establish display support.
Chaining: use one suitable length; no supported daisy-chain count is published.
Condition: keep dry, avoid heat, crushing and tight bends, and stop using damaged or unusually hot connections.

Questions buyers ask.
Is UGREEN 10387 active or passive?
Passive. It has no signal-repeater module and no auxiliary-power input. The full source-to-device path must remain within the limits of the negotiated mode.
Can it really transfer at 10Gbps?
It supports up to 10Gbps USB 3.2 Gen 2. Real speed depends on the host, device, storage media, downstream cable or hub, controller and protocol overhead.
How does 100W charging work?
It passes a compatible USB PD negotiation up to 20V/5A. The charger, extension, any downstream component and receiving device must all support the requested profile; otherwise charging uses a lower shared level.
Will it charge at 100W with any USB-C charger?
No. 100W is the supported ceiling, not a fixed output. A lower-rated charger or device remains lower-rated, and some chains require an appropriately rated 5A cable and electronically marked components.
Does it support 4K at 60Hz?
Up to 4K60 is supported only when the USB-C source port offers DisplayPort Alt Mode and the downstream adapter/cable/display supports the same resolution, refresh rate and link configuration.
Can it add video to my USB-C port?
No. A data-only or charging-only USB-C source remains unable to output native display video. The extension passes a compatible mode; it does not create one.
Is it a Thunderbolt 3 or Thunderbolt 4 cable?
No. It may plug into compatible Thunderbolt USB-C ports for supported USB/PD/video modes, but it is not specified for 40Gbps Thunderbolt transport or every Thunderbolt device topology.
Will it work with a USB-C dock?
Simple hubs may work when total length, power and modes fit. Active Thunderbolt hubs, complex docks, multi-display functions and high-power combinations are not universally guaranteed; follow the dock maker’s extension guidance.
Can I daisy-chain two of these cables?
Do not plan a chain. UGREEN does not publish a supported extension count, and every added junction reduces data, video and power margin. Use one cable and test the full workload.
Why does reversing a plug sometimes change behaviour?
USB-C is mechanically reversible, but a marginal or complex extended chain can expose connector, adapter or cable implementation issues. Reseat both ends, test direct, then reintroduce one component at a time.
What should I test before permanent routing?
Test sustained file transfer, full display resolution/refresh, charging under load, sleep/wake, hot-plug and reconnection. If any mode fails, shorten and simplify the chain.
