It's really very inconvenient. Okay, before people traveled a little around the world, now it's practically not a luxury. Remember, when household appliances assembled in Europe began to arrive in Russia, how many problems there were with our Soviet sockets. Bought adapters, they burned. Only not so long ago finally got rid of this problem.
I was in Cyprus in the spring - there are quite unusual British sockets. In a small town in Russia, you can’t buy adapters; upon arrival, you had to run around there, look for them, overpay. Soon I'm going to the Dominican Republic - and there again there are other sockets, American ones (sort of). Adapters will again have to be bought on the spot and not in 1 copy.
And all why...
In the era of electrification, inventors from different countries offered their own options for optimal sockets; different types of electric generators were built around the world.
First, the struggle of technologies at the dawn of the development of electricity left its mark. We are talking about the opposition of Thomas Edison and Nikola Tesla in the creation of DC and AC networks, respectively. Although we know that AC power plants eventually won out, the DC infrastructure built in the US up to the 1920s (and in Stockholm up to the 1950s) has to be maintained and used right up to the present day. .
Secondly, many inventors offered their own options for optimal (in their opinion) sockets. For example, in 1904, the American inventor Harvey Hubbel received a patent for the first electrical outlet. By its design, it was a kind of adapter for an electric chuck-plug. The adapter was screwed into the cartridge instead of a light bulb, and some electrical appliance was connected to it.
The German engineer Albert Büttner created the "Euro socket" known to us today in 1926. And the first socket with grounding was created by Philippe Labre in 1927.
And the national companies involved in the installation of electrical networks supplied their devices suitable for these networks. Accordingly, different types of plug connectors and sockets were introduced and their own networks were designed. The developments of other countries were completely ignored.
Influenced the development of sockets and the availability of materials. For example, during the Second World War in Great Britain they came up with a three-prong plug with a short copper fuse. This design made it possible to save copper reserves for military needs. Curiously, the use of the 3-pin plug in the UK was in stark contrast to the rest of Europe and even North America, where 2-pin plugs were widely used and also differed in design, all because of the lack of communication in the early days. power supply development.
Now, according to one classification, 12 types of sockets are distinguished, according to another - 15. Moreover, sockets of one type sometimes accept plugs of another. However, having learned that in the country where you are going, the same type of outlet as at home, do not rush to rejoice! This solution is only half the problem. In different parts of the world, the voltage and frequency of the current may vary.
Classification of types of sockets and plugs in different countries of the world
The most common are two standards: European - 220-240 V at a frequency of 50 Hz and American - 100-127 V at a frequency of 60 Hz. You should not check what will happen if an electrical appliance operating from 100-127 V is plugged into a socket with 220-240 V.
In some countries, you have to keep your eyes open at all. For example, in most parts of Brazil 127 V is used, but in the north of the country 220 V is found. And in Japan, the voltage is the same everywhere - 110 V, the frequency is different: 50 Hz is used in the east, 60 Hz in the west. The reason is simple: first, German-made generators with a frequency of 50 Hz were purchased for Tokyo, and shortly after that, American generators with a frequency of 60 Hz were supplied to Osaka.
Perhaps someday a single standard will be adopted. A universal socket for all types of plugs has already been developed. But for now it's up to everyone whether to install it or not. In addition, you first need to come to a single voltage standard. And this rests on the huge financial costs of re-equipment and re-equipment of transformer substations, replacement of sockets and plugs.
* Voltage 100-127V @ 60Hz is used by USA, Canada, Japan, Mexico, Cuba, Jamaica, part of Brazil and other countries.* Voltage 220-240 V with a frequency of 50 Hz is used in most other countries, but even with the same parameters, the type of sockets can vary greatly.
Here is a brief description of some of them:
Types A and B - American socket
Type B differs from A in that it has a third hole, which is for the ground pin. Such sockets, as you might guess from the name, were invented in the USA and distributed in North, Central and partly South America, as well as Japan and some other countries.
Types C and F - European socket
Just like A and B, types C and F differ only in the presence of grounding - F has it. The European socket is used in most EU countries, as well as in Russia and the CIS, Algeria, Egypt and many other countries.
Type G - UK socket
In the UK, the socket has three flat holes, and this design appeared for a reason. The fact is that during the Second World War the country experienced a shortage of copper. Therefore, a plug with a short copper fuse and three plugs was developed. In addition to Great Britain, the same socket is used in Cyprus, Malta, Singapore and other countries that have experienced the influence of the British Empire.
Type I - Australian socket
This type of outlet can be found not only in Australia, but also in New Zealand, Fiji, the Cook Islands, Kiribati, New Guinea, Samoa and sometimes in China, where types A and C are also common.
Type H - Israeli socket
Type H is used only in Israel and Palestine, and the pins of the plug can be either round or flat, depending on when the device was manufactured. The flat shape of the outlet was in the old technique, but the new outlets fit two options.
Type K - Danish socket
This outlet can easily claim to be the "friendliest" in the world - its design resembles a smiling face. In addition to Denmark and Greenland, which is part of it, type K is used in Bangladesh and the Maldives - however, several types of sockets are common there at once.
Fortunately, all these differences will not spoil your vacation or business trip - you just need to purchase a suitable adapter in advance.

But for a long, long time we discussed . And here is the specifics of the American temperature:
This article lists all types of electrical plugs and sockets used in countries around the world.
This is the so-called American type and plugs. The plug has two flat parallel contacts. It is used in most countries of North and Central America, in particular in the United States, Canada, Mexico, Venezuela and Guatemala, and also in Japan. And also in countries where the voltage in the network is 110 volts.
Type B
Similar to type A connector, but with an additional round contact . Used in everyday life in the same regions of the world as plugs and sockets type A. 
Type C
This is our native European socket and plug type. The plug has two round pins parallel to each other. There is no third grounding contact in its design. This is the most popular type and socket in European countries, except for the United Kingdom of Great Britain, Ireland, Malta and Cyprus. Used in everyday life, where the mains voltage is 220 volts. 
Type D
This is an old British type with three round pins set in a triangle shape. In this case, one of the contacts is thicker than the other two. This type of sockets and plugs is used for the maximum current value in the power grids of countries such as India, Nepal, Namibia and the island of Sri Lanka. 
Type E
This type has an electric plug with two round pins and a hole for the grounding contact, which is located in the socket. This type of plug socket is currently used in Poland, France and Belgium. 
Type F
Models of this type are similar to models of sockets and plugs type E. Only instead of a round ground contact, two metal clips are used here on both sides of the connector. This type of sockets and plugs is used, as a rule, in Germany, Austria, Holland, Norway and Sweden.

Type G
This is a typical British socket and its friend is a plug with three flat pins. It is used in apartments and private houses in the UK, Ireland, Malta, Cyprus, Malaysia, Singapore and Hong Kong. Note - sockets of this type of construction are often produced with an internal fuse built in. Therefore, if after connecting the device it does not work, then the first thing to do is to check the condition of the fuse in the outlet, perhaps it is in it. 
Type H
This design of socket connectors and, accordingly, plugs, is used only in the State of Israel and in the Gaza Strip. The socket and plug have three flat pins, or in the earlier version, the round pins are arranged in a B shape. Not compatible with any other plug. It is intended for networks with a voltage of 220 V and a current of up to 16 A. 
Type I
This is the so-called Australian outlet. It, like the electrical plug, has two flat contacts, as in the American type A connector, but they are located at an angle to each other - in the shape of the letter B. There are such sockets and plugs with a grounding contact. These models are used in Australia, New Zealand, Papua New Guinea and Argentina. 
Type J
Swiss type electrical plugs and sockets. The plug is very similar to its Type C counterpart, but has an extra ground pin in the middle and two round power pins. They are used not only in Switzerland, but also abroad - in Liechtenstein, Ethiopia, Rwanda and the Maldives. 
Type K
Danish electrical sockets and plugs. The type is similar to the popular European type C socket, but additionally has a grounding contact located at the bottom of the connector. It is the basic standard in the countries of Denmark and Greenland, as well as in Bangladesh, Senegal and the Maldives. 
Type L
Italian plug and socket. The model is similar to the popular European type C, but has an additional round ground pin located in the center, two round power pins are unusually in line. Such sockets and plugs are used in Italy, as well as Chile, Ethiopia, Tunisia and Cuba. 
Type M
This is an African socket and plug with three round prongs arranged in a triangle shape, with the ground prong clearly thicker than the other two. It looks like a type D connector, but it has much thicker contacts. The socket is designed to power electrical devices with a current of up to 15 A. It is widely used in South Africa, Swaziland and Lesotho. 
Note to tourists, migrants and hunters for seasonal discounts in foreign shopping glasses. Having curbed the power of electricity a long time ago, contented humanity could not really agree on uniform standards for its operation - in the 21st century it would be reckless to travel without a set of adapters.
Ordinary electrical sockets in different countries have different designs. If you happened to travel outside your country, then you probably noticed this feature. This difference is due to many factors, some of which we will reveal below.
Why are socket types different?
First of all, the process of development of electrical networks was not uniform throughout the world, which naturally affected the shape of the outlets produced. Also, do not lose sight of the fact that in different parts of our planet people used various types of power generators to generate energy, and this also had its impact on the design of the connectors. In addition, the shape of the sockets also depended on the companies involved in the installation of electrical networks in a particular region, since these companies supplied equipment created by them and compatible with their networks.
Some of the old connectors in the corrected form are still used in some countries, but over time they decided to abandon many of them, since they did not meet safety standards. Moreover, there are no uniform standards even within the power grids - in different regions, the frequency of current and voltage may be different.
For example, in the USA, Canada, Brazil, Japan, Mexico, Jamaica, Cuba and a number of other countries, a voltage of 100-127 V at a frequency of 60 Hz is used, while the rest use a voltage of 220-240 V at a frequency of 50 Hz. At the same time, the design of the connectors is different even if the parameters are the same.
Basically, there are 12 types of sockets (another classification has 15). Consider their characteristic features:
American connectors: types A and B
From the name itself, you can understand that these sockets were developed in the USA. Accordingly, they are distributed in Central, North and South (partly) America, as well as in Japan. Connector B differs from A in having an additional hole for a grounding pin.
European connector: types C and F
The most familiar options for sockets. As in the previous case, they differ in the presence of a separate hole for grounding. Distributed in the CIS, in many EU countries, in Algeria and Egypt.
British plug: type G
The peculiarity of the device of sockets in the UK was due to the fact that during the Second World War the country experienced a shortage of copper. For this reason, a plug had to be developed with three plugs and a small copper contact.
In addition to Great Britain, type G was also common in countries previously under the influence of the British Empire (Singapore, Cyprus, Malta, etc.).
Australian connector: type I
This socket design can be found in Australia, New Zealand, New Guinea, Fiji, Samoa, Kiribati and the Cook Islands. Also, the connector is used in some regions of China.
Israeli connector: type H
This type of outlet is common only in Israel and Palestine. The plugs on the plugs may differ - be round or flat - but both options are compatible with this connector.
Danish connector: type K
Used in Denmark, Maldives and Bangladesh. It has the most "friendly" design.
All the presented variety of connectors is overcome by pre-purchased corresponding adapters. This will protect the traveler from unnecessary hassle while visiting another country.
It's no surprise that universal chargers are held in high esteem by startup fans. Major manufacturers of consumer electronics have their own answer to the age-old question - Apple, for example, releases its own World Travel Adapter Kit. At the same time, in the vastness of AliExpress you can find.
According to yablyk
Mains adapters for plugs and sockets are divided into two main types:
- for equipment brought from abroad, the plugs of which do not fit into Russian standard sockets;
- for sockets that will be needed in another country to connect devices with Russian standard plugs.
Almost all adapters are manufactured by ANTEL. Available in any quantity!
We sell socket adapters to organizations and individuals - we work for cash, as well as by bank transfer.
Those who travel to different countries are often faced with the incompatibility of plugs on electrical appliances with sockets. Therefore, more experienced tourists foresee such a situation in advance and put one or two adapters into an outlet in their travel suitcase - a simple device into which our plug is inserted, and the device itself is inserted into a “foreign” outlet. And often the opposite happens: the equipment brought from abroad does not want to be inserted into our socket. And the voltage is suitable, and everything else suits, but the pins on the plug are not the same or not so located. There are more than a dozen different standards for household sockets in the world, some of them are joined without anything, but basically adapters are needed for such cases. ANTEL has carefully studied this issue and produces adapters for sockets for almost all occasions.
A little help on the types of adapters to the outlet:
- 2 flat parallel pins, used in North America, Canada, Japan, Cuba, etc.,
- 2 flat parallel pins and a third round pin in the middle,
- 2 round pins (Russian standard),
adapter type "D" - "old British" - three round pins,
adapter type "E" - on the plug there are two round pins and a hole for grounding,
adapter type "F" - a common socket for us with grounding spring contacts,
- three thick flat pins, used in England, Singapore, Cyprus, etc.,
adapter type "H" - three flat pins diverging from the center at an angle of 120 degrees,
- two flat pins rotated 60 degrees, or three pins (Australian standard);
- three round thin pins, the central pin is slightly offset, used in Switzerland, etc.,
adapter type "K" - on the plug there are two round pins and a thick ground socket,
- three round thin pins in one line, used in Italy, etc.,
- two thick pins and the third central one is even thicker, used in India, South Africa, etc.,
adapter type "N" - two flat pins at an angle of 120 degrees.
Socket adapters can be simple, designed to connect one type of connector to another. And there are also combined universal adapters (for example, the so-called), designed to be compatible with several combinations of sockets and plugs at once. When choosing an adapter for a socket, you need to pay attention to the quality of the contact group: the plug must enter the socket with force, sit tightly in the socket and be removed with force. You also need to pay attention to the permissible current load. If you have any doubts about whether the plug adapter will withstand your load, contact the experts for advice, you can find all the contact information on our page "".
