This power cable consists of a USB A male connector on one end and a 3.5mm x 1.35mm male DC connector on the other end. It is typically used to supply power to 5V devices from a USB port rather than a AC/DC transformer.
Very Convenient in Certain Situations
Turn a USB A male port into a power port in order to supply power to devices. For example, you can use your TV or surge protector with USB ports to power a device such as a switch, splitter or extender. Another option would be using the USB port on your computer to power peripherals like an external drive.
