<p>A portable power system for use with an electrical device. The system includes a portable power storage device, a motor, a controller, an alternator, an inverter, and a first monitor. The portable power storage device provides a DC voltage. The first monitor generates a first indication related to a characteristic of the portable power source. The controller monitors the primary power source delivering primary power to the electrical device, couples the portable power storage device to the inverter for generating an AC output, and selectively drives the motor in response to the first indication. The alternator is responsive to the motor for converting mechanical motion of the motor into an electrical signal for use to recharge the portable power storage device.</p> |
