Standard Wall Outlet Voltage

When traveling abroad, the format of the outlet and the voltage in the network is important, because each of us will need to charge our mobile phone, laptop or tablet. Most power supplies for electronic devices such as laptops, chargers, mobile devices, camcorders, and cameras have a universal power supply, so they are capable of operating at a supply voltage of 100 to 240 volts, and a frequency of 50 or 60 Hz.

There is two standard wall outlet voltage in the world: European – 220-240V and American 100-127V. And two AC frequency standards: 50Hz and 60Hz. USA, Japan, and most South American countries use 100-127V 60Hz bundle. The rest of the world mainly uses European 220-240V 50Hz. In addition, there are several countries in the world with different variations of voltage and frequency, for example, the Philippines, where a voltage of 220-240V with a frequency of 60 Hz is used.

MAP-SCHEME OF USE IN DIFFERENT COUNTRIES OF THE WORLD VOLTAGE AND CURRENT FREQUENCY

Electrical outlet standards have evolved independently in most countries, so for the most part, plugs and sockets from different countries are not compatible with each other.

Summary table of outlet types, voltage, and frequency by country

There are a great many ways to connect to the electrical network, different types of plugs and sockets, and for a tourist (coupled with different voltages and frequencies), such a variety turns into a serious problem.

Of the many connections, 13 of the most commonly used types of sockets are distinguished, denoted by Latin letters from A to M :

Type A, non-grounded American socket	Two vertical flat pins	USA, Japan
Type B, US grounded socket	It differs from type A in the presence of a central D-shaped earthing rod	USA, Canada, Central America
Type C, Europlug, Euro socket, European non-grounded socket	Two round pins	Europe
Type D	Two thin and one thick round pins	still stayed in Britain
Type E, French socket	Two round prongs on plug and one on socket	France
Type F, Schuko, European earthed socket	Two round pins, like type C, lugs for grounding	Europe
Type G, English (UK) socket	Two rectangular horizontal and one vertical pin	UK, Malaysia, Singapore
Type H, Israeli socket	Three flat (old) angled or round pins	Israel
Type I, Australian socket	Three angled flat pins	Australia, New Zealand
Type J, Swiss socket	Two round pins like type C, center pin different from type F. Special shape of the plug.	Switzerland
Type K, Danish socket	Similar to French Type E, but the center D-shaped grounding prong has been moved to the plug	Denmark
Type L, Italian socket	Three round pins in a row	Italy
Type M	Similar to British Type D but with thicker pins	South Africa

To connect electrical appliances to networks with outlets of an unsuitable format, various adapters and adapters are used. There are universal sockets that allow you to connect devices with several types of plugs at once.

In which countries besides the USA is the 100 – 127 V standard widespread?

Here is a list of countries where 100-127 V networks are used. This should be taken into account if you are planning to go on vacation abroad.

As you can see, there are not so few countries where the voltage is 100-127 V.
