We have seen enormous technological advancements in recent years and rarely is there someone who is not using one gadget or another device on a personal level as well as in their household. No doubt accessories like plug adapters have become indispensable items for us because it allows us to plug our gadgets into various outlets all at the same time. When we are travelling internationally, it is also vitally important to know about the international plug adapters’ specifications and the country of use. 

Needless to say, we must have in-depth knowledge about this item like its different classifications, etc so that we can procure the best one for us. Moreover, we need to learn about the safety measures that we must follow to avert any electrical mishaps or device harm. So, in this article, we will elaborate on all these aspects simply and comprehensively. Let’s begin by trying to understand what a plug adapter is.  

Plug Adapter—What is it Actually?
A plug adapter is a small device that acts as a plug for various electronic devices. This means that it transforms ...
... the electrical energy into a specific voltage that is best for the device to which it is connected. This transformation is a must because all the devices that we use today have different plug specifications for optimal performance.  For example, the voltage requirement of a laptop is different from that of a smartphone.

Plug Adapters Types
We will talk about the NEMA plug adapters and other types of plug adapters here. They vary in shape, size, and voltage capacity from country to country. Let’s get a detailed understanding of it:

1. NEMA 1-15 - Type A
This plug has two flat, parallel pins sidewise with no grounding pin. It functions in North America and Japan and is suitable for Type A and Type B sockets. This type is used in lamps and small appliances.

2. NEMA 5-15—Type B
Among the NEMA Plug adapters, this plug is of 15A, 125V capacity and functions in North America. It has two flat, parallel, conducting tongues and a cylindrical earthen connection pin making it shockproof. It is suitable for common electrical appliances and electronic devices. 

3. Europlug - Type C
This is a universal plug adapter with two pins functioning in Europe. It has two round pins and without an earth pin withstands a maximum of 250 voltages. It is a versatile item in many countries.

4. Type D
This is the AC adapter plug type, which is commonly used in India and some African countries. It features one larger pin at the top and three round pins arranged in a triangle. Its voltage capacity ranges from 220 to 240 volts. 

5. Type E
Countries like France, Belgium, Poland, etc., use this plug type and can be plugged into Type C sockets. They are circular, tapered, smaller pins with two holes and a socket for the male earthing pin. This type of plug is especially suitable for travellers. 

6. Schuko - Type F
This is a universal plug adapter with a capacity of 16 amperes and 250 volts used mostly in European countries. For security, it contains two side earth clamps and two rounded, sharp freelance prongs. 

International Plug Adapter Types
The most common international plug adapters are types A and B. The former has flat parallel pins, while the latter has a central grounding pin. The Type C is used all across Europe and has two round contacts. In the UK, Type G is very popular with three rectangular contacts. Type I sockets and plugs are used in Australia and New Zealand with two flat pins in a V shape with one for earthing. Therefore, for an individual who intends to visit different countries, universal adapters or converters will be required to enable the use of electronic products safely and efficiently.

Are the plug adapters safe?
We have mentioned some of the rules that you should follow while using any plug adapter, be it the international plug adapters or the NEMA plug adapters, to avoid any unforeseen danger. Here are the tips:

Always select a plug adapter that matches your device's voltage and current ratings to avoid overheating.
Purchase branded adapters with UL or CE marks to negate safety issues. 
Prolonged use of plug adapters must be stopped to avert the risk of an electrical fire.
Check the state of the plug adapters from time to time and replace them whenever necessary to ensure safety.

Final Words
Having a deep understanding of the various adapter types allows one to charge their devices uninterrupted. While travelling, we suggest that you should regularly check on the type of international plug adapters that are suitable for your place of visit. Moreover, the user should follow the protective measures while using the regular plug adapters. The user should also take surge protection measures to avoid incidences of accidental fire and electrocution and increase the life expectancy of electronic devices.
