Zusammenfassung:	Power adapters having Universal Serial Bus (USB) Type-C (USB-C) receptacles acting in a USB Power Delivery (USB-PD) sink mode are disclosed herein. The USB-C receptacle can be connected to a USB-PD source via a USB-C cable. The power adapter further includes a socket in electrical communication with the USB-C receptacle that receives a removable (interchangeable) barrel plug of a size corresponding to the barrel receptacle of an output device to be powered by the power adapter. The power adapter uses a USB-PD controller to communicate with the USB-PD source via the USB-C receptacle to request that power be provided at a desired direct current (DC) voltage by the USB-PD source to the USB-C receptacle. The power so received is then delivered between the USB-C receptacle and the socket. From the socket, the power travels through the attached removable barrel plug and to the barrel receptacle of the output device.
