Review on Dell Power Adapter 90 Watt MKN5F by Lisa Stephens

Dell cables are designed to fail. There is a notch on the main stone around which the cable should be wrapped - this is how the charger is supplied. Unfortunately, this is a sharp turn and parts of the cable will break over time. As a result, your computer cannot be charged through the cable. It will be able to draw enough power to run but not enough to charge. Basically, Dell's monstrous design turns your highly portable laptop into a non-portable desktop.
