Double Insulated: Double insulated appliances are products that have been designed in a way so as not to require a safety connection to electrical earth.  Typically,it's that third prong on the power cord plug.  The basic requirement is that no single failure can result in dangerous voltage becoming exposed so that it might cause an electric shock, and that this is achieved without relying on a connected-to-earth metal casing.  This is usually achieved at least in part by having two layers of insulating material surrounding live parts or by using reinforced insulation.
