Dell Slim Power Adapter, 90-Watt (MKN5F) Neatly wrapped cords and cables fit snugly around the adapter for less bulk in your bag. The LED indicator lets you know it's on, and makes it easy to find in a dimly lit space. Up to 3X smaller than our previous models, and 30% less bulky than other leading adapters (including cables). Every detail has been carefully considered - from soft, bendable cables to smooth, rounded corners.
