Hybrid electric device

A device, comprising:

• a housing configured with a working element;
• a motor configured for urging motion of the working element;
• a power control module in electrical control of said motor, the power control module in electrical connection with a first power source and a second power source, the first power source being a battery assembly having a Direct Current (DC) power output, and the second power source being a power inverter receiving Alternating Current (AC) power from an AC power input line, the power control module having a power selection switch for selectively connecting at least one of the first power source and the second power source with the motor to cause said motor to urge motion of the working element;
• a charge switch for selecting between a first mode for charging the battery assembly when the power control module is receiving AC power and a second mode for not charging the battery;
• and
• a charge controller for controlling battery assembly charging when the first mode of the charge switch is selected,
• wherein the charge controller comprises logic embedded in the power control module.
