USB-C 3.1 extension cable 20 cm

This 20 cm USB-C 3.1 male-to-female cable extends the reach of a USB-C port on a Mac, tablet, mobile phone or hard-disk drive. The reversible Type-C connectors plug in either way up, removing the frustration of incorrect orientation. Its compact length keeps a desk or bag tidy while maintaining the full USB 3.1 data path. The black finish matches most modern devices.

Thermals noise and power

The cable draws power only from the host port and adds no active components, so it generates no measurable heat and runs completely silent. Scalable power charging is supported, allowing the host to negotiate the appropriate current for the connected device. Voltage drop over the short 20 cm run is negligible for typical peripherals. No fan, pump or external supply is involved.

Reversible connectors and scalable charging

The reversible plug orientation means the male and female ends insert correctly on the first try, reducing wear on device ports. Scalable power charging lets the cable carry the negotiated current required by phones, tablets or portable drives without a separate power adapter. The 20 cm length is suited to close-range connections such as a dock or hub on the same surface. No driver or software installation is needed.

Questions about this item

How do I connect the 20 cm USB-C 3.1 male-to-female extension to my device without forcing it?

Align the reversible USB-C plug with the port; the oval shape only fits one way up, but both orientations work — push straight in until it clicks, never twist.

Will the cable’s connectors wear out from daily plugging and unplugging?

The USB-C interface is rated for thousands of insertion cycles; keep the ports free of dust and avoid side loads to maintain reliable contact over time.

What limits sustained data throughput on this 20 cm extension?

Cable length and signal integrity cap performance at the USB 3.1 specification; longer runs would degrade speed first, but at 20 cm the link stays within spec.
