The present invention provides an electrical coupling device for use with an electrical device. In one embodiment, the electrical coupling device comprises: (1) a cable having multiple insulated conductors, a centerline, and first and second ends, (2) a first electrical connector having a first longitudinal axis coincident with the centerline wherein the first electrical connector is coupled to the first end and the first electrical connector is couplable to a power outlet, (3) a second electrical connector having a second longitudinal axis coincident with the centerline wherein the second electrical connector is coupled to the second end and the second electrical connector is couplable to an electrical device, and (4) a strain relief structure substantially surrounding the cable and having a length that extends from the first electrical connector to the second electrical connector and a flexibility along its length, with the strain relief structure further coupled to the first and second electrical connectors, and wherein the flexibility is capable of allowing the centerline to resiliently flex such that the second longitudinal axis may deviate at least about 90 degrees from the first longitudinal axis.
