Abstract
An electrical power supply device includes a DC-DC power convertor receiving an input voltage and producing an output voltage, a first and second port connected to the DC-DC power convertor supplying electrical power to a first and second consumer device, and a device controller connected to the DC-DC power convertor, the first and second port. The memory device controller stores instructions to command the DC-DC power convertor to produce the output voltage between a first voltage threshold and a higher second voltage threshold when only the first consumer device is connected to the first port. The memory stores additional instructions which commands the DC-DC power convertor to produce the output voltage at the first voltage threshold when the first consumer device is connected to the first port and the second consumer device is connected to the second port.
