USB 2.0 Micro-B cable for mobile devices

This three-foot cable connects a standard USB-A port to a slim Micro-B connector on smartphones and tablets. It is built for users who need a short, flexible link for charging and data sync without excess length.

Slim moulding keeps cases on while charging

The low-profile Micro-B plug fits through most protective case openings so the device stays covered during use. Nickel-plated contacts and foil-plus-braid shielding preserve signal integrity at the rated transfer speed.

USB 2.0 limits throughput to 480 Mbps

The 28 AWG conductors and USB 2.0 interface cap data rates at 480 megabits per second, so large file transfers take longer than on newer standards. The cable carries only USB 2.0 power and signalling, not alternate modes or higher voltages.

Questions about this item

Will the 28 AWG conductors need replacement after repeated bending?

The 28 AWG wire gauge and PVC jacket are built for regular flexing; inspect the connectors periodically and replace the cable only if the Micro-B plug becomes loose or the jacket shows cracking.

What limits sustained throughput on this USB 2.0 link?

The USB 2.0 specification caps the data rate at 480 Mbit/s, so the cable itself does not impose a lower ceiling under continuous transfers.

Does the aluminum-mylar foil with braid shielding keep the cable cool during all-day charging?

Shielding protects signal integrity, not thermal output; the cable carries standard USB 2.0 current, so it remains at near-ambient temperature during extended use.
