Generally, a world adapter is not necessary when traveling through Europe, provided that you are visiting countries where the C or Schuko socket 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.

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. This way, you can ensure that you have the right adapters with you to use your electronic devices safely and smoothly during your trip through Europe.
