1. A portable electrical power supplying system for use in an ambient environment and supplying AC electrical power to AC electrical power consuming devices, and DC electrical power to DC electrical power consuming devices, said portable electrical power supplying system comprising:

  • an electrical power supplying docking station having a module docking receptacle, within which a first module dock interface is mounted;

    said electrical power supplying docking station including (i) an electrical power cord with a power plug for receiving an AC line voltage supplied from a standard AC power receptacle, (ii) an AC electrical power conditioning circuit for conditioning the AC line voltage to produce AC electrical power for use in said portable electrical power supplying system, (iii) a voltage level sensing circuit for automatically detecting changes in the AC line voltage supplied from the standard AC power receptacle, and also (iv) an AC/DC power conversion circuit for converting AC electrical power to DC electrical power for supplying within said electrical power supplying docking station;

    said electrical power supplying docking station supporting (i) a plurality of AC power receptacles for supplying AC electrical power to AC electrical power consuming devices using AC electrical power cords, and (ii) one or more USB-type DC power receptacles for supplying DC electrical power to DC electrical power consuming devices using DC electrical power cords;

    a multi-function dockable module, dockable within said module docking receptable, and supporting (ii) an emergency-light illumination mode and a night-light illumination mode when said multi-function dockable module is docked within said module docking receptacle, and (ii) said night-light illumination mode when said multi-function dockable module is removed from and located outside of said module docking receptacle;

    wherein said multi-function dockable module further includes(i) a battery power storage subsystem, including a rechargeable battery, for storing DC electrical power supplied by said AC/DC power conversion circuit in said electrical power supplying docking station,(ii) a solid-state light emitting assembly energizable by DC electrical power supplied by said battery power storage subsystem,(iii) a light level sensing circuit for sensing the light level in said ambient environment,(iv) a subsystem controller being responsive to said voltage level sensing circuit for controlling the supply of DC electrical power from said battery power storage subsystem to said solid-state light emitting assembly during said emergency-light illumination mode, and said subsystem controller also being responsive to said light level sensing circuit for controlling the supply of DC electrical power from said battery power storage subsystem to said solid-state light emitting assembly during said night-light illumination mode, and(v) a second module dock interface for interfacing with said first module dock interface when said multi-function dockable module is docked within said module docking receptacle so that said first and second module dock interfaces interconnect, and DC electrical power is supplied from said AC/DC power conversion circuit in said electrical power supplying docking station to said battery power storage subsystem in said multi-function dockable module, as needed to recharge said rechargeable battery;

    wherein during said emergency-light illumination mode, said voltage level sensing circuit detects changes in the AC line voltage from the standard AC power receptacle, and in response to detected changes in the AC line voltage, said subsystem controller automatically controls the supply of DC electrical power from said battery power storage subsystem to said solid-state light emitting assembly so that said solid-state light emitting assembly produces visible illumination for emergency lighting in said ambient environment; and

    wherein during said night-light illumination mode, said light level sensing circuit detects changes in the light level of the ambient environment, and in response to detected changes in the light level of the ambient environment, said subsystem controller automatically controls the supply of DC electrical power from said battery power storage subsystem to said solid-state light emitting assembly so that said solid-state light emitting assembly produces visible illumination for night-lighting in said ambient environment.
