Mauritania.

220 V · 50 Hz on Type C.

About as simple as a national listing gets: two-pin round Type C only, at 220 V and 50 Hz. Anything with a europlug works directly; earthed Schuko and French plugs will not seat in a plain C socket, so carry a two-pin adapter for larger devices.

The voltage window

A nominal 220 V supply may legitimately sit anywhere between 198 and 242 V (±10%). Dual-voltage gear (marked 100–240 V) shrugs at all of it.

Coming here from somewhere else?

Pack an adapter — Mauritania runs 220 V 50 Hz on Type C — and your 120 V appliances need to be dual-voltage or transformed, adapter or not.
