Does Nha Trang need an adapter?

There are two voltages in Vietnam, 220V and 1 10V, but the main voltage is 220V, and the frequency is 50HZ, which is the same as the domestic standard. However, unlike China, Vietnamese sockets are German-style double-hole sockets, which are two cylinders. Unlike in China, portable electronic products need plug converters if they use three pins. In Vietnam, you can directly ask the front desk of the hotel, or you can buy a German standard plug converter in China in advance.

If you don't want to bring it, you can consult the hotel in advance. Better hotels will install universal jacks or usb ports.
