I claim the ornamental design for a case with power supply and cable storage compartment for a mobile communications device, as shown and described.
FIG. 1 is a front isometric view of a case with power supply and cable storage compartment for a mobile communications device showing my new design.
FIG. 2 is a rear isometric view thereof;
FIG. 3 is a front elevation view thereof;
FIG. 4 is a left side elevation view thereof;
FIG. 5 is a right side elevation view thereof;
FIG. 6 is a top view thereof;
FIG. 7 is a bottom view thereof;
FIG. 8 is a rear elevation view thereof; and,
FIG. 9 is an exploded isometric view thereof with the rear and front portions of the case separated to clearly disclose the rear power supply and cable storage compartment.
The broken lines throughout the drawing figures depict an environmental mobile communications device and an environmental cable that form no part of the claimed design.
