Abstract: An example power adaptor includes a converter and a circuit to detect an overcurrent event at the converter and to pause power output of the converter when the overcurrent event is detected. The circuit is further to count a number of overcurrent events at the converter within a time period. The circuit is further to compare the number of overcurrent events to a threshold number and to switch off the power output of the converter when the number of overcurrent events passes the threshold number.
