A bag for transporting tools and building supplies includes a body, a first spool, a second spool, an electrical plug coupled to a first electrical cord, and an electrical connector coupled to a second electrical cord and defining an electrical outlet. The body includes a side panel coupled to and extending from a base member. The base member and the side panel cooperate to define an internal volume. The first spool and the second spool are each rotatable relative to the body and positioned within the internal volume. The first and second electrical cords wrap around the first and second spools, respectively, and extend outside of the body. The electrical plug is electrically coupled to the electrical connector. The electrical plug is interfaces with an external power source such that the electrical outlet receives electrical power from the external power source.
