Power cords are electrical wires that carry electrical current. The current transmission is usually point-to-point. Power cords can be divided into AC AC power cords and DC DC power cords according to the purpose. Usually AC power cords are wires with higher voltage AC power. Due to the high voltage, these wires require unified standards to obtain safety certification before formal production. The DC line basically passes direct current with a lower voltage, so the safety requirements are not as strict as the AC line, but for safety reasons, countries still require unified safety certification.
