Dell 240W USB-C Laptop Adapter

The Dell 330-4342 is a 240-watt AC adapter designed to keep select Dell laptops running at full performance, even during demanding sessions. It supplies 19.5 volts at 12.3 amps through a 7.4 millimeter by 5 millimeter barrel connector, delivering the steady power that gaming rigs such as Alienware x15 R1, M15, M17x, and M18x, as well as mobile workstations like Precision M6600, M6700, and M6800 expect.

Because the adapter accepts any standard outlet from 100 to 240 volts and 50 to 60 hertz, you can travel between regions without packing a separate voltage converter. A six-foot cable lets you place the laptop on a desk, a coffee-shop table, or a conference-room podium while the wall plug stays out of the way.

Whether you are rendering large design files, compiling code, or exploring open-world games that push graphics settings to the limit, this adapter provides a reliable source of power that prevents battery drain and keeps performance consistent. It is also a practical spare for users who move between home and office or who want a dedicated adapter inside a travel bag.
