I claim the ornamental design for a C5 AC power cord, as shown and described.
FIG. 1 is a front perspective view of the C5 AC power cord design;
FIG. 2 is a front elevational view of the C5 AC power cord design;
FIG. 3 is a rear elevational view of the C5 AC power cord design;
FIG. 4 is a top plan view of the C5 AC power cord design;
FIG. 5 is a bottom plan view of the C5 AC power cord design;
FIG. 6 is a left-side elevation view of the C5 AC power cord design; and,
FIG. 7 is a right-side elevation view of the C5 AC power cord design.
In FIGS. 1, 2, 3, 6 and 7, the CS AC power cord is shown with a symbolic break in its length. The appearance of any portion of the article beyond the break line forms no part of the claimed design. Throughout the drawings, the broken lines represent unclaimed subject matter only and form no part of the claimed design.
