Liberia uses Type C, Type D, Type F, Type G outlets at 230V, 50Hz. Sockets are typically universal and accept additional plug types (A, Type B, Type C, Type D, Type E, Type F, Type G, Type I, Type O), which matters for travellers from countries with different native plugs.
Note: Almost all sockets in Liberia are universal ones which accept either types A, B, C or types A, B, C, D, E, F, G, I, O.
