A cover plate for covering a wall box mounted wiring device such as an electrical receptacle. The cover plate includes an attachment member for covering the wall box opening, at least one opening for at least one wiring device, and a shelf attached to the attachment member. The shelf may also have a non-slip surface or be pitched in such a way that an electronic device such as a cell phone will not fall off. The shelf may also have a lip or raised edge to retain the electronic device. In use, an electronic device will rest on the shelf while charging. The charger plug will be conveniently inserted into the electrical receptacle that is directly below the shelf, with the electronic device resting neatly on the integral shelf. The cover plate reduces clutter related to charging electronic devices in areas such as kitchens or bathrooms. The cover plate may also be used to hold other items such as keys, wallets, watches, clocks, remote controls, and the like.
