Abstract: Disclosed is a system for aiding in determining when a power-providing outlet is ending its usable service life and is due for service or replacement. A connection detection unit (102) and counting unit (103) respectively monitor connection of a device to a port (101) and maintain a connection count of connection events. For USB type C connections a cable or device resistance detection circuit can be used to determine if a USB type C device or cable has been connected. USB Type A and AC connections can be detected by mechanical or electrical mechanisms. When a connection has been detected a counter can be incremented or decremented to record a connection. A limit value can be set and compared to the connection count and a sensory or electronic indication can be made when the limit value is exceeded.
