This number is listed for a variety of Dell laptops, but it's important to know the exact model number within the product lines. It was listed for the 7000 series but I now know that a specific model (7559) requires a much higher output (130) rather than the 45-65 watts provided by that product. It was easy to return the product and then find the exact model of the product - which has already arrived and works perfectly.
