USB Male to DC 1.7mm x 4.0mm Male Plug Power Cable

Description
This is a DC Power plug converter. If you want to connect the USB port to the Adapter, you can use it. It has 2 different heads, one side is USB type and the other one is DC Power Plug connector.
DC connectors have many more standard types that are not interchangeable.
The dimensions and arrangement of DC connectors can be chosen to prevent the accidental interconnection of incompatible sources and loads.
Cylindrical plugs usually have an insulated tip constructed to accept the insertion of a pin. The outer body of the plug is one contact, most often but not always the negative side of the supply. Inverted polarity plugs can, and do, damage circuitry when plugged in, even if the voltage is correct; not all equipment is equipped with protection.
