USB 3.0 female-to-female coupler

This adapter joins two USB-A cables to extend their reach while keeping a stable connection. It is suited for users who need a longer link to a flash drive or peripheral in a tight space. The pack contains two couplers for spare or multiple setups. Plug-and-play operation requires no driver installation.

5 Gbps bandwidth and 2 A power headroom

The USB 3.0 interface supports up to 5 Gbps data transfer and delivers up to 2 amps of power. It remains backward compatible with USB 2.0 and 1.1 devices. For reliable data transfer the combined cable length should stay under five metres; for charging the combined length should stay under three metres. Beyond those lengths signal quality and power delivery may degrade.

USB-A connector limits

The coupler uses standard USB-A female ports on both ends and does not support USB On-The-Go functionality. It cannot act as a host adapter for direct device-to-device links. The physical length of each coupler is 124.5 mm, which sets the minimum added distance between the two joined cables.

Questions about this item

Will the 124.5 mm female-to-female adapter work with my older USB 2.0 cables?

Yes, the USB 3.0 port is backward compatible with USB 2.0 and 1.1 interfaces, so existing cables will connect and function at their rated speeds.

How can I verify the adapter is delivering the 5 Gbps data rate after I plug it in?

Transfer a large file between two USB 3.0 devices and check that the sustained throughput approaches the 5 Gbps specification; speeds will fall back to USB 2.0 rates if either connected cable or device is only USB 2.0.

Does the 2-pack include any extra cables or do I need to supply my own?

The package contains only the two female-to-female adapters; you must provide the USB cables you wish to join.
