What more can I say? This is your regular, common power cable. You probably have a bunch of them around the house, but you can never find one when you need it. We have a handful of them here, as they are commonly used with amplifiers (like Acoustic Image, Euphonic Audio, Traynor, Genzler, and many others) as well as preamps that have an integrated power supply (like the Grace or Audio Sprockets preamps).
One one end is a standard, grounded plug (for use in the USA and Canada) and the other end has the common IEC 60320 C13 connector.
