That's what I often hear to, and refer to myself, as a 'figure 8' type power cord. If you look at the end of it, it looks like the number 8.
If it is flat on one side, I call it a flat figure 8 power cord.
If it has hot, neutral, and ground, and follows the same format, it looks like Mickey Mouse, so that is easy to call out as well, but harder to find.
The most standard power connector is the D-type which is on most monitors, TVs, electronics, and computers. Also called an IEC cable, but IEC is a ton of standards, not just a single cable. Still, the D power cord, or the IEC cable is most common.
Yours? Just a standard figure 8 power cable. Tons are out there. Do not overspend!!!
