These standard duty Power Cords are available in many standard stock lengths. This cord is typically used to power a computer. The 3-prong plug fits into a standard wall outlet. The C13 mates with a C14 inlet (which is typically used on a computer). The NEMA 5-15P and C13 are rated at 15 amps, but most computers require less than 10 amps. Consult your owners manual to see if you can use this de-rated power cord. Black is the standard color, but other colors are available
