An electric power washer contains a main body having a pump and an electric power source, a hose, a handle, and a control circuit. The hose contains a first end fluidly-connected to the pump and a second end fluidly-connected to the handle, which has a button operatively-connected to the control circuit, which is operatively-connected to the pump and the electric power source. The control circuit controls the pump output and contains a timer. The control circuit permits the pump to normally operate at up to 100% normal power. However, when the button is activated, the control circuit permits the pump to operate at a boost power mode of from about 103% normal power to about 300% normal power. The control circuit intermittently pulses the boost power mode and terminates the boost power mode after a predetermined period of time or when the button is no longer activated, whichever is shorter.

The various implementations described herein include apparatuses and methods used to operate engine-based equipment using an electric starter motor. In one aspect, a method for operating an apparatus includes starting an electric starter motor. In response to starting the electric starter motor, the electric starter motor is coupled to a flywheel and the flywheel is turned. In response to turning the flywheel, an engine coupled to the flywheel via a power take-off of the engine is started. After starting the engine, the electric starter motor is decoupled from the flywheel and thus from the engine, and the engine is used to turn the flywheel, thereby enabling operation of a primary assembly coupled to the flywheel.

A hybrid engine and battery generator and a method of operating the same. The generator is controlled to operate in at least three modes: a battery-only mode, a battery charging mode, and a boost mode. In the battery-only mode, the engine is off and an internal battery of the generator is used by an inverter to generate AC output. In the battery charging mode, the engine generates DC power, via an alternator and rectifier, which is used to charge the battery and to supply power to the inverter to generate AC output. In the boost mode, the battery and the engine generate DC power that is used by the inverter to generate an AC output with increased wattage, relative to the battery-only mode and battery charging mode. The generator automatically switches between the modes based on battery level and load demand.
