Bangladesh uses Type A, Type C, Type D, Type M, 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: Most sockets in Bangladesh are universal ones which accept types A, B, C, D, E, F, G, I, O.
