1. A power adapter, comprising:

  • an ac-dc converter configured to convert an input ac voltage to an intermediate dc voltage;

    at least two output ports configured to output the intermediate dc voltage respectively;

    at least two dc transmission cables, wherein a second terminals of the at least two dc transmission cables are detachably connected to the at least two output ports respectively and configured to receive and transmit the intermediate dc voltage respectively; and

    at least two connectors, connected to first terminals of the at least two dc transmission cables respectively, wherein each of the at least two connectors comprises;

    a first housing;

    a dc-dc converter enclosed in the first housing and configured to convert the intermediate dc voltage to an output voltage to an external device; and

    an output terminal is detachably connected to the external device to directly transmit the output voltage to the external device, wherein a node of the output terminal enclosed in the first housing is directly connected to the dc-dc converter to receive the output voltage and another node of the output terminal is plugged into the external device to directly transmit the output voltage to the external device,wherein the at least two connectors are detachably connected to the external devices and provide adjustable output voltages to the external devices respectively.
