Expats and international travelers usually worry about the difference in electrical current per country. Generally, electric sockets in Ho Chi Minh City accommodate plugs with either two flat-pins or two round-pins. However, you will occasionally encounter rectangular three-pin support. The electrical current in Vietnam is 220 volts, 50Hz. A good traveller always carry portable adaptors just in case you have gadgets that have different voltages. You can buy a multi-adaptor in any electrical equipment shop.
