Why do I see charging stations marked by different icons and symbols?

Different icons indicate different scenarios:
● White Pin: indicates a charging station that you have booked or you are currently using
● Thunder icon: indicates Fast charging stations, with Power up to 50 kW or higher than 150 kW
● Logo Commercial partners: charging stations near Enel commercial partners are shown with specific icons corresponding to the category of activity (bar and restaurants, hotels, supermarkets, shopping centers and entertainment)
● Grey PIN: It indicates the Charging Stations managed by other operators
