1 to 2 Outlet Power Extension Cable has a main 3 prong plug which can be divided into 2 shunts, is the perfect way to turn a single outlet into 2, better than a power strip. Each outlet gets its own cable so you can plug in large adapters or any size plug without covering the other outlets compatible with both 3 prong grounded cords and 2 prong electrical cords, allowing for more flexibility and better organization.
