help
A charger which is connecting and disconnecting frequently
can indicate damage to the charger or port. To prevent
excessive power usage on a device plugged in and
experiencing frequent AC connects, we monitor the number of
AC connects over a period of time. If the number of AC
connects exceeds a defined value during that period of time,
we inhibit all chargesplash requests until an entire period
passes with no new AC connections.
This config option defines the length of the period, in
seconds.
