What this adapter powers

This 65 W AC adapter supplies 19.5 V at 3.34 A through a 4.5 mm barrel connector with a centre pin. It replaces Dell part numbers MGJN9, G6J41, 43NY4, 332-0971 and the 492 series for the listed Inspiron, OptiPlex, Vostro, XPS and Chromebook models.

Check your device before ordering

Confirm your laptop or micro desktop requires a 19.5 V input and accepts a 4.5*3.0 mm barrel plug with a centre pin. Verify the Dell part number on your original charger matches MGJN9, G6J41, 43NY4, 332-0971 or a 492 variant. Ensure the model name appears in the supported list above.

Thermals, noise and power draw

The unit delivers up to 65 W continuously and runs silently with no moving parts. Normal operation produces modest warmth at the brick and connector. It draws only the power needed by the attached device up to the 65 W limit.

Questions about this item

Does the box include a mains cable or only the 4.5 mm barrel adapter?

The adapter is supplied as a single unit with the 4.5 mm barrel connector; a separate mains cable is not included.

Which Dell part number should I match when choosing between MGJN9, G6J41 or 43NY4?

All three part numbers refer to the same 65 W, 19.5 V, 3.34 A adapter with a 4.5 mm barrel, so any of them will fit the listed models.

Will the 65 W rating actually charge an XPS 13 9350 while it is running heavy workloads?

The adapter delivers 19.5 V at 3.34 A, providing up to 65 W, which matches the power requirement for the XPS 13 9350 under load.
