You most likely won't find something that holds the same current as the C13/14 plug, but it is likely overkill for what you're going to be doing (125V x 15A = 1875W). I've successfully used a polarized C7/8 cord before which will carry 125V @ 10A (1250W) and is much smaller.
The C5/6 Cloverleaf you often see on laptop bricks is another option that has the same amperage limit as the C7/8 but is slightly larger due to having a third wire for ground (this may or may not be important to you). Handy reference here:
