USB 3.0 Mini to Micro cable 12 ft

This 12 ft USB 3.0 extension cable connects a Mini USB host port to a Micro USB device. It is designed for users who need to extend the reach of external hard drives, printers, keyboards, cameras, flash drives or card readers beyond the length of the standard cable. The cord supports SuperSpeed data rates up to 5 Gbps while remaining fully backward compatible with USB 2.0 equipment. It suits desktop or Windows tablet setups where the peripheral sits farther from the host than a stock lead allows.

Shielded construction and durable connectors

Tin-plated bare copper conductors, foil and braid shielding protect signals from EMI and RFI interference, preserving the 5 Gbps transfer rate over the full length. Gold-plated contacts are rated for more than 10000 insertion cycles and resist corrosion. A metal wire braid inside the PVC jacket makes the cable flexible and resistant to pulling or dragging during daily use. These features reduce the risk of intermittent connections caused by cable fatigue or connector wear.

Simple plug-and-play installation

No drivers or software are required; the cable functions immediately when both ends are seated firmly. The only common issue is loose contact if the Mini USB or Micro USB plug is not fully inserted, which can drop the link to USB 2.0 speeds or cause disconnects. Ensure the connectors click into place and avoid sharp bends near the ends to maintain reliable performance.

Questions about this item

How many times can I plug and unplug the gold-plated Mini USB and Micro USB connectors before they wear out?

The gold-plated connectors are rated for more than 10000 insertion cycles.

Will the 12 ft length still deliver the full 5 Gbps USB 3.0 speed, or does the distance cut the rate?

The cable supports SuperSpeed USB 3.0 at up to 5 Gbps across the full 12 ft length.

Does the PVC jacket and internal metal braid keep the cable cool and quiet when it runs all day?

The PVC case is anti-abrasive and the metal wire braid adds flexibility, but the cable carries only data and low power so it produces no audible noise and negligible heat.
