Here are two Sony AC-E455A 4.5V Adapters for the Sony CD Walkman and some other products. These are original Genuine OEM products. Both were tested. Both work well. They both have the same model # (AC-E45AA), but one is 400mA and has a smaller plug to fit CD Walkmans, and the other is 500mA with a slightly larger plug to fit some other Sony portable devises. The smaller one is about 2 inches by 1 1/2 inch, and the larger is 2.5 inches by1 3/4 inch. Please see photos that will show all of that and are what you get and are part of this description. These items have been stored in a climate-controlled, smoke-free indoor environment. As with most original vintage items, it's not possible to offer a guarantee.
