Which charging connector do guests with an electric car use?

There is no fixed connector name to give, as the standard for charging points at residential properties is determined per country and sometimes differs between neighboring countries. Therefore, ask your installer or supplier which standard is common in your country for new charging points, and have this confirmed before installation. Guests with an electric car typically bring their own cable that is compatible with their country of purchase or the common standard; if in doubt, you can ask this in advance or request a photo of the cable. If you have multiple properties in different countries, you will need to check this separately for each location.
