The Dell N7MWW is a 180 watt AC adapter built for Dell laptops that require consistent, high-capacity power. It attaches through a 7.4 mm by 5.0 mm barrel connector and delivers a steady 19.5 volt DC output, allowing the computer to operate at full performance while the battery charges.
The adapter handles input from 100 to 240 volts AC, so it works in most regions around the world when paired with the correct plug adapter. Engineers using Precision mobile workstations can render large models without throttling, gamers on Alienware systems can maintain stable frame rates, and students with Inspiron notebooks can stream lectures or edit projects for hours without worrying about battery drain.
Dell’s electrical and thermal safeguards protect the laptop against voltage fluctuations, making the adapter a dependable choice for offices, classrooms, and home setups alike. A one year limited warranty adds an extra layer of confidence for anyone who relies on their laptop every day.
