The PowerCrew 15-amp in-box power supply provides a safer solution for in-box power that works in any brand or style of jobsite box. It has four GCFI-protected electrical outlets for operating tools or charging batteries. The power source comes via a standard three-prong/straight blade extension cord, which plugs into the outside of the box. PowerCrew replaces the unsafe practice of jerry-rigging power solutions for jobsite boxes. It also includes safety features such as an internal relay to sense broken wires and an LED power indicator.
