Claim 10:
11. A method for charging a portable power supply unit while providing power to one or more electronic devices connected to said portable power supply unit comprising the steps of:
providing, via a portable power supply unit, power to said one or more electronic devices comprising the steps of:
providing, via a first battery in said portable power supply unit, a first DC output to at least one first inverter in said portable power supply unit;
converting, via said first inverter, said first DC output to a first AC output to a power output in said portable power supply unit;
electrically coupling said power output to said one or more electronic devices;
charging, via a portable power charging unit, said first battery comprising the steps of:
providing, via a second battery of said portable power charging unit, a second DC output;
converting, via a second inverter in said portable power charging unit, said second DC output to a first AC input;
transmitting said first AC input of said portable power charging to said portable power supply unit;
utilizing said first AC input at said portable power supply unit said first AC output, whereby said first AC input is provided to said power output of said portable power supply;
simultaneously utilizing said first AC input at said portable power supply unit as a power input to said first inverter of said portable power supply unit;
converting, via said first inverter, said first AC input to a first DC input; and
transmitting, via said first inverter, said first DC input to said first battery to charge said first battery of said portable power supply unit by said first AC input from said portable power charging unit at the same time as said first AC input from said portable power charging unit is used to supply AC power to said one or more electronic devices via said power output of said portable power supply unit.
