The plug format in Oman is type G, which is the same as that used in the UK. This means that you will need a travel adapter to use your electronic devices with type A, B, C, D or E sockets.
It is important to note that the electrical voltage in Oman is 240 volts, which is higher than that used in some countries, such as the United States (120 volts) or France (220 volts). So make sure your appliances are compatible with this voltage before using them in Oman.
It is also advisable to bring an extension lead if you intend to use several appliances at the same time, as there may be few sockets available in some hotel rooms.
