This Maplin Premium USB-A 2.0 Cable uses a male USB-A 2.0 to male USB-A 2.0 connector and is uncommonly used to connect devices that use a female USB-A 2.0 port in place of micro or mini connections. This cable is compatible with USB 3.0 but limited to USB 2.0 transfer speed. Please note: This cable is not recommended to be used as a file transfer cable between two computers.
