  • Connector TypeMicro USB to USB A
  • OTG function lets phones read flash drives directly

  • 100 % tested before dispatch for reliable operation

Connector and use case

This Micro USB to USB A OTG cable adapter lets Android smartphones, tablets and MP3 or MP4 players connect flash drives, keyboards or other USB peripherals. It supports USB 3.1 on the Micro B side and USB 2.0 on the Type A side for data transfer and charging. The adapter is aimed at owners of legacy Micro USB devices who need on-the-go host functionality. It does not serve users who require USB-C connectors or USB 3.0 speeds on the host port.

Thermals noise and power

The passive adapter draws power only from the host device and has no active cooling, so it produces no audible noise and adds negligible heat. Normal use stays within the USB 2.0 current limits of the connected smartphone or tablet. There is no fan, radiator or external power supply to consider. Builders who need a powered hub for high-draw peripherals should look elsewhere.

Bundled value

The package contains only the adapter itself; no extra cables, drivers or software utilities are included. Immediate plug-and-play operation means no installation steps are required on supported Android devices. The lack of bundled accessories keeps the form factor compact for travel. Users who want a multi-port hub or a USB-C variant will need a separate product.

Questions about this item

How do I connect the Micro USB plug to my Android phone without bending the port?

Insert the Micro USB male end straight into the phone's port, then plug a USB-A flash drive or peripheral into the female USB-A socket; forcing the connector at an angle is the step most users get wrong.

Will the USB-A female socket wear out after repeated flash-drive insertions?

The adapter uses a standard USB-A female port rated for typical insertion cycles; no user-serviceable parts exist, so the whole cable is replaced if the socket becomes loose.

What transfer speed will I see when copying large files continuously through this adapter?

The link operates at USB 2.0 speeds, so sustained throughput is limited to the 2.0 interface rather than the 3.1 designation on the Micro USB side.
