Electrical sockets (outlets) in Swaziland are the “Type M ” South African SABS1661 (“Large” 15 amp BS-546) sockets. This is actually an old British standard. The “Type M ” South African plug and socket is not to be confused with the “Type D ” Indian plug and socket. In pictures, they look very similar, but the South African type is much larger than the Indian type, and they are physically incompatible. If your appliance’s plug doesn’t match the shape of these sockets, you will need a travel plug adapter in order to plug in. Travel plug adapters simply change the shape of your appliance’s plug to match whatever type of socket you need to plug into.
Electrical sockets (outlets) in Swaziland usually supply electricity at between 220 and 240 volts AC. If you’re plugging in an appliance that was built for 220-240 volt electrical input, or an appliance that is compatible with multiple voltages, then an adapter is all you need.
But travel plug adapters do not change the voltage, so the electricity coming through the adapter will still be the same 220-240 volts the socket is supplying. North American sockets supply electricity at between 110 and 120 volts, far lower than in most of the rest of the world. Consequently, North American appliances are generally built for 110-120 volts.
