For your say: " Power cords have one purpose: deliver 120 volts a few feet from a wall outlet".
In my country as well as in many other, its 230V @ 50Hz.
Power cables are tested as so:
Take that "super expensive and fancy" new power cable and exchange with it, your kitchen kettle cord.
Boil some water and make yourself a cup of tea.
If that taste any better than the one you made with the original cable
($ 1.50), than the "super expensive and fancy" worth its weight in gold!
But if not, it worth just as much as $ 1.50...
