1. An electronic device comprising:
a power source;
a port for connecting the electronic device to a secondary electronic device to provide power from the power source to the secondary electronic device;
a power limiter coupled to the power source and the port for adjusting power provided to the secondary electronic device over the port; and
a power management controller coupled to the power limiter and configured to:
determine that the secondary electronic device requires an amount of power that exceeds a default power threshold defined in a default power scheme;
monitor internal power requirements associated with on-board functions of the electronic device and determine that the internal power requirements satisfy predetermined criteria; and
in response to determining: a) that the secondary electronic device requires an amount of power that exceeds the default power threshold; and b) that the internal power requirements satisfy the predetermined criteria, adjust a power scheme associated with the port and implemented by the power limiter to provide, to the secondary electronic device, an amount of power that exceeds the default power threshold.
