Hello! We will be staying in Lisbon and Faro in Portugal, and Sevilla and Malaga in Spain, one month this spring. I have several adapters but the place in Faro sent a picture of a rounded, recessed plug with two round prongs. I have two pronged, but not rounded and recessed.
The place in Lisbon said the same thing. What adapters have you used in those cities in Portugal and Spain?
I've traveled to both and used the same adapter that the rest of continental Europe uses and that the RS store sells.

Wrote a trip report that has a photo of the adapters we used, it's a long report you'll have to scroll, think it's post #47.

Those round receptacles are common throughout Europe. You do not need a round adapter--the simple one in the RS link will work.
we've used this , it has the usual plug, as well as USB and USB-C...
