Abstract:
1. A method of charging a plurality of small chargeable electronic devices, comprising the steps: a. providing a base unit with a housing having an input port and a plurality of output ports disposed along an outer surface of the housing; b. inputting a predetermined first direct current voltage into the base unit through a connector of the input port, c. routing the predetermined first input voltage directly to a first respective pin of each of the plurality of output ports, d. additionally routing the first predetermined input voltage through a DC to DC switching regulator that changes the first voltage to a second voltage different from the first voltage and routing the second voltage to a second respective pin of each of the plurality of output ports, and e. additionally routing the predetermined first input voltage through resistors to a third respective pin of each of the plurality of output ports, wherein the resistors providing the first predetermined voltage to the third pin of each of the plurality of output ports all have the same resistance, wherein each of the plurality of output ports is adapted to detachably connect to one of the plurality of small chargeable electronic devices and whereby, you may charge the plurality of electronic devices at the same time regardless of battery types.
