1. A portable electrical device comprising:a power supply;
an output device configured for generating an output having an output power between a minimum output power level and a maximum output power level;
a charging channel configured for transmitting electrical current from the power supply to a separate electrical device; and
an onboard controller configured to, upon detecting a separate electrical device connected via the charging channel, decrease the maximum output power level of the output device; and
the output device is configured to generate an output having an output power at a first output power level; and
the onboard controller is further configured to:
detect the separate electrical device connected via the charging channel while the output device is generating an output having an output power at the first output power level; and
adjust the output power to a second output power level less than the first output power level.
