In general, a universal adapter is not necessary if you are traveling through Europe, provided you are going to countries where the C-type or Schuko plug system is used. The C socket, also known as the Europlug, is the most common socket type in Europe and is used in countries such as the Netherlands, Belgium, Germany, France, Spain, and Italy, among others.

If you plan to travel to other European countries, it is useful to check which type of sockets are common there. Some countries, like the United Kingdom, Ireland, and Malta, for example, use a different type of socket, namely the G plug. In that case, you will need a suitable adapter to connect your electronic devices.

It is advisable to check the socket types and electrical standards of the specific countries you are going to visit before departure. That way you can ensure that you have the right adapters with you to use your electronic devices safely and without any problems during your trip through Europe.
