A multi-port power monitor is provided which indicates whether power is being supplied to one or more of a plurality of ports connected to external devices. The multi-port power monitor comprises a plurality of serially connected indicators and a plurality of controllable switches which supply power to the individual indicators when one or more of the corresponding ports are active. Because the indicators are connected in series, rather than in parallel, the same current passes through each illuminated indicator thereby avoiding the need for a large power resistor or a large AC capacitor for each individual port.
