Abstract: A charging system for wirelessly charging a smart device positioned over the charging system with a charger connectable to an electrical power source for charging the smart device, like a smartphone, and can be inserted inside a furniture through an opening located at its top surface; a fixing element compatible with the opening and affixed to the charger for maintaining the charger fixably engaged inside the opening below the top surface; and a removable cap for capping the fixing element. When the removable cap is made of a transparent material, the charging system is configured to provide an advertising message presented on a support affixable to the bottom surface of the transparent cap, the message being then visible through the transparent cap.
