Mains supply in Côte d’Ivoire: 230 V, 50 Hz, sockets of Types C and E. At 230 V the supply matches what UK and European appliances expect, so no converter is needed.
The same socket system is used in Burundi, the Western Sahara, Congo, The Democratic Republic of the and Mauritania, so one adapter covers all of them. Travelling further to Lesotho, Ghana and Malawi means a different adapter. In Africa, 21 of 55 recorded destinations use exactly this combination.

Grounded and ungrounded sockets may occur
Earthed sockets (Type E) and unearthed ones (Type C) exist side by side. For metal-bodied appliances the protective-earth path is what matters.
