Maybe a little clear description of your goal. You linked to a basic three conductor power cord, intended to replace a damaged tool cord (my puppy went through a couple, but either spliced, or replaced with one I saved). He stopped after messing up an extension cord, that I had left plugged in, oops...
i want to make kind of Christmas lights. i have a series and parallel leds, 172 of them, which requires 4 9V batteries to power it up. Instead of wasting batteries i just want to use an outlet.
So like christmas lights. The plug i have is already polarized. and have a power supply is bulky.
i know, i just dont understand why i need a power supply.
chistmas lights dont have them, phone chargers have that outlet to usb convertor.
how does all that work?
Because most Christmas lights aren't LED's, the ones that actually are LED based either have a power supply or have the number of LEDS in series/parallel carefully valued for the AC voltage, yours were designed to run off a fixed DC voltage, so that's what you have to provide it.

That has nothing whatsoever to do with it rudster, all that means is that one of the prongs is larger than the other so it can only be plugged into an outlet in one direction, it's a basic saftey feature on many electrical products.
All the cable you have can do is supply the wall outlet power (which we don't know because we don't know your location) from one spot to another.
