For the current iPhones and iPods, is anything more than a plug adapter required in foreign countries?

That is, do these Apple products require any sort of voltage adapters beyond something to change a US plug (2 flat verticals) into the plug of a foreign country?

Some Apple products can internally handle 120V-240V, but I could not find any indication if the phones and iPods have the capability.


On a Mac since 1984.
Currently: 24" M1 iMac, M2 Pro Mac mini with 27" BenQ monitor, M2 Macbook Air, MacOS 14.x; iPhones, iPods (yes, still) and iPads.
