The invention is a device (1) for wireless charging, in particular telephones in a car comprising two charging surfaces (2). The car heats a car antenna (3) and each charging surface (2) comprises at least one coil for generating a magnetic field. The wireless charging device also comprises a system for passive amplification of the mobile signal comprising a signal splitter (4) and two antenna structures for the charging surface (2). The signal splitter (4) is connected to the antenna (3) of the car, with one antenna structure for the charging surface (2) at one charging surface (2) and the other antenna structure for the charging surface (2) at the other charging surface (2) . Passive signal amplification can be used to compensate for the deterioration in mobile signal quality caused by car shielding, without requiring expensive components and without making it impossible to charge two phones at the same time.
