Abstract: A portable power unit comprises a battery pack interface configured to receive a battery pack and a power tool interface that is configured to electrically connect to an external power tool. The portable power unit further comprises a tool control circuit configured to generate a tool control signal. The tool control signal is operable to control power provided to the external power tool. The portable power unit further comprises a bypass circuit configured to provide power from the battery pack to the external power tool. The portable power unit further comprises a controller configured to determine whether the external power tool is operable to be controlled by the tool control circuit and to control the bypass circuit to provide passthrough power to the power tool interface when the external power tool is not operable to be controlled by the tool control circuit.

Abstract: A concrete vibrator system comprises a vibrating head including a shaft. The shaft has a center of mass that is radially offset from a rotational axis of the shaft. The vibrating head also includes an onboard electric motor configured to provide torque to the shaft, causing the shaft to rotate. The concrete vibrator system further comprises a portable power unit including a battery pack configured to provide electrical current to the motor. A cable extends between the portable power unit and the vibrating head. The cable is configured to transmit electrical current from the battery pack to the motor and a motor control signal from the portable power unit to the motor.
