Before you pack: Madagascar uses Types C and E, 230 V and 50 Hz. At 230 V the supply matches what UK and European appliances expect, so no converter is needed.
Handy for multi-stop trips: Equatorial Guinea, Côte d’Ivoire, Congo and Mauritania use the same plug types. Nearby but different: Zimbabwe, the Gambia and Uganda – an adapter for Madagascar will not fit there. 21 of the 55 destinations in Africa share the plug types of Madagascar.
Protective earth
Grounded and ungrounded sockets may occur
Not every socket in Madagascar is earthed: Type E yes, Type C no. Class I appliances belong in an earthed outlet.
