The PowerCrew 15-amp in-box power supply provides a safer solution for in-box power on the jobsite. It has four GCFI-protected electrical outlets providing 15 amps of power for operating tools or charging batteries. Safety features include an internal relay that senses an open neutral conductor preventing electricity from reaching a person who may contact the open wire, and a red LED that indicates the four outlets have power and are ready for use.
