USB 2.0 cable for micro-B devices

This Monoprice 8640 cable connects a USB Type-A host to any device with a USB Micro-B 5-pin port. It is built for charging and syncing smartphones, tablets, cameras and similar peripherals that still use the older micro connector. The 3.00 ft length keeps a desktop or bedside setup tidy without excess slack.

Type-A to Micro-B with strain relief

The male Type-A plug fits standard computer ports, hubs or chargers while the micro-B end seats securely in the device. Molded connector heads and integrated strain relief boots protect the solder joints from everyday bending. Gold-plated contacts resist corrosion for reliable mating cycles over the cable's lifetime.

28/24 AWG conductors with ferrite core

Data lines use 28 AWG conductors and power lines use 24 AWG conductors, supporting USB 2.0 transfer rates and standard charging current. A single ferrite core suppresses high-frequency noise that can cause data errors. The cable is not suited for USB 3.0 or newer speeds, nor for devices that require USB-C or Lightning connectors.

Questions about this item

How long is the 8640 cable before voltage drop becomes an issue?

The cable is 3.00 ft (0.9144 m) long and uses 24 AWG power conductors to minimise voltage drop over that distance.

Does the ferrite core or shielding add noticeable heat during all-day use?

The single ferrite core and shielding suppress interference without generating measurable heat; the cable stays cool during continuous operation.

Which port must my device already have for the micro B plug to fit?

Your device needs a USB micro B 5-pin port; the cable's other end plugs into a standard USB Type-A socket.
