I posted my question in Beyond Europe and no one responded so I will try again here. We are going to Patagonia next March and will visit both Chile and Argentina. I consulted this chart to see what kinds of plug adapters we will need:
We will have only one iPhone and one iPad, both of which we have charged in Europe with a Type C two-pin adaptor. Chile uses the same kind so we are OK there. My question concerns the Type I plug adaptor which we will need for Argentina. (The same type is used in Australia.)
Type I includes both two-pin and 3-pin versions. Is there any reason we can't just take and use the 2-pin Type I ones we already have? They are smaller and flatter than the one shown in the photo, but do have the two angled flat prongs. They much easier to pack than the bulky 3-pin one.
I am thinking the 3-pin one is grounded and the 2-pin one is not, but does this matter for an iPhone or iPad?
