I'm going to Argentina and Chile and have a couple of electronic devices I want to charge. I have Swiss plugs consisting of two bolts:
What kind of adapter should I pack for Argentina and Chile?
As always, Wikipedia has a good list which can answer this question. See: https://en.wikipedia.org/wiki/Mains_electricity_by_country which has info, specs, and pictures for each plug type by country.
It looks like Chile and Argentina have different mains plug types and you may only need an adapter for Argentina.
In Chile, ungrounded plugs are compatible with Europlugs, so you should be able to use the Swiss plug directly. Some sockets only accept grounded plugs, which have a round grounding pin directly between the two round power pins. Apparently similar plugs are used in Italy, but I had never seen an adapter for it before I came to Chile.
I have no recollection of the kind of plugs used in Argentina, even though I was there recently. My packing checklist for that trip says Type I adapter, like for Australia and China. As I had no trouble with charging my equipment, that should have been the correct adapter.
You may want to look into getting one adapter to fit "all."

The individual ones can be small and easy to lose. There is some interesting insight here regarding bringing power strips:
