Electronic devices that provide notification of and data about power outages. The devices include a voltage input receiver for receiving voltage from a power source; a voltage monitor for monitoring a reference voltage that is received from the power source; a change in voltage detector for detecting a change in the reference voltage with respect to a threshold voltage; a microprocessor; a programmable real-time clock to provide current date and time data; input/output devices for communicating data to the microprocessor; a display to display data transmitted by the microprocessor; and an auxiliary energy power supply that provides power to the device during any power outage. During a power outage, the date and time of the outage are stored and the device is powered by the auxiliary power source. Once power is returned, the date and time of restored power are stored; the duration of the outage is calculated; and the signal indicates that there has been an outage.
