Dell 240W Power Adapter for Precision, Alienware, Latitude & Inspiron Laptops

The Dell J938H is an original 240W AC power adapter that keeps select Dell laptops running at full performance. It is built for Precision mobile workstations, Alienware gaming rigs, Latitude business models, and the Inspiron 11 3162, so one adapter can serve a range of systems across your day.

This unit delivers 19.5 volts at 12.3 amps through a 7.4 mm barrel connector. The steady, high-capacity output lets the computer draw the power it needs during video editing, 3D rendering, or extended gaming sessions without forcing the battery to pick up the slack.

An input range of 100 to 240 volts means the adapter handles most regional wall power with no extra converters, which is especially useful for consultants, students, and travelers who move between countries or offices. The included mains cable plugs straight into a standard outlet, so setup is immediate.

Keeping a second J938H in a backpack, at a client site, or in a living-room workstation prevents the scramble that follows a misplaced charger. Because it is a genuine Dell accessory, firmware on compatible laptops recognizes it instantly, reducing warning messages and ensuring proper charging rates. Dell backs the adapter with a one-year manufacturer warranty for additional peace of mind.
