Go stick it in the wall socket. That isn't quite as simple as it seems if you're outside of your familiar environment.
Not only do different countries or regions use different single-phase voltages (110, 117, 120, 220, 230, 240v) but electricity is also generated in two frequencies (50 or 60 Hz). These numbers are much less of a concern than when I first started traveling in the 1980s because most small devices generally come with built-in, multi-voltage power adapters nowadays.
Yet even if your device will run on a different electrical system doesn't mean you easily get to the 'go-go juice'.
I just looked up Argentia as that's where we'll be for three months from just before Christmas until mid-March. We'll be all set if the apartment we're renting has type C as these are interchangeable with E and F and common in Europe and Asia. Jay and I have a dozen of this type of wall socket adapter sitting around.
However, type I is common in Argentina and the Internet suggests is also used in Australia, New Zealand, and China. Although I've visited those countries, I don't think I've ever plugged anything into an outlet shaped like this. If our Airbnb in Buenos Aires requires this type of plug, I hope adapters are commonly-found and cheap.
