1. A system for providing power comprising:
a portable power supply unit comprising:
a first battery providing a first DC output;
at least one first inverter for converting said first DC output to a first AC output and for converting a first AC input to a first DC input for charging said first battery;
a power output receiving said first AC output and configured to be electrically coupled to one or more electronic devices such that power is supplied from the first battery to the one or more electronic devices;
a first charging port in electrical communication with said first battery and said power output; and

a portable power charging unit comprising:
a second battery for providing a second DC output;
a second inverter for converting said second DC output to a second AC output; and
a second charging port configured to be electrically coupled to the first charging port of the portable power supply unit such that said second AC output is provided to said power output of said portable power supply unit in replacement of said first AC output to supply power from said power output of said portable power supply unit to the one or more electronic devices without interruption, and at the same time said second AC output being provided to said at least one first inverter as said first AC input for conversion of said first AC input into said first DC input for charging said first battery of said portable power supply unit from said second battery of said portable power charging unit.
