Quest USB Charging Wall Plates are the easiest way to add USB Fast-Charging Wall Plates to any standard indoor duplex or decor electrical outlets. Installation is super easy! All you need to do it remove the existing wall plate and replace is with the USB wall plate using the same screws. Both outlets remain free when you plug in up to two smartphone devices. The Decor wall plate has a convenient smart phone stand molded into the faceplate so that it can sit along the wall and out of the way – instead of on the floor.
