Angled therefrom, the storage area extends over a lower housing section in which the mains socket is arranged.

In particular, the charger comprises a housing with a front side which extends around the mains socket and from which the storage surface extends at an angle.

A stop is preferably arranged on a lower edge of the storage surface.

This can in particular be designed as an angle.

In this way, the user can place his mobile device over the mains socket, which is designed as a through socket, without it falling down.

At the same time, the inclination of the storage surface increases its length or avoids the need to provide a housing with a great depth.

The housing of the charger can be composed, in particular in a side view, essentially of a rectangular section and a triangular section, the stop protruding at the transition from the rectangular to the triangular section.

Stop and storage surface can in particular be designed in one piece. It can in particular be provided that the storage surface, the stop and the front of the housing extending around the mains socket are designed as a one-piece upper housing component with which the housing of the charger is closed.

According to a preferred embodiment, the housing has a height between 100 and 150 mm and / or a width between 60 and 80 mm.

The storage area is preferably essentially rectangular.

The stop preferably extends over the entire width of the storage surface.

The length of the shelf preferably corresponds to at least the height of the front of the housing section with the mains socket.

In the case of a compact design, this is achieved in particular by the sloping shelf.

The storage area preferably does not protrude beyond a lower housing section. In a preferred embodiment of the invention, only the stop designed as an angle protrudes beyond the front of a lower housing section.

The storage area can in particular have a width of 60 to 80 mm and / or a length of 50 to 100 mm, preferably 60 to 90 mm.

According to a development of the invention, the charger comprises at least one charging connection with which a mobile device can also be charged that is not designed for wireless charging.

The charging connection can in particular be located on the side and / or on the front of the lower housing section next to the mains socket.

A mobile device that is not designed for wireless charging can also be placed on the storage surface and connected to the charging connection via a charging cable.

The charging connection is preferably arranged in the housing section of the mains socket, that is to say in particular in the lower housing section.
