Compatibility Check

Verify that your laptop requires 19.5 V and uses a 7.4 mm by 5.0 mm connector before ordering. Confirm the model appears in the supported list, which covers Alienware 13, 15, 17 and m17 variants including R2 through R5 revisions, Area-51m, X51, M11x, M13, M14X, M15X, M17X, M18X, Precision 7510, 7520, 7530, 7710, 7720, 7730, M4300, M4600, M4700, M4800, M6400, M6500, M6600, M6700, M6800, G3, G5, G7 and models 3579, 3590, 3779, 5587, 5590, 7588, 7590, 7790.

Ideal Use Cases

Suits owners of listed Alienware and Precision laptops needing a 240 W replacement or spare charger with the exact 7.4 mm by 5.0 mm tip. Not for users whose devices require a different voltage, connector size or higher wattage than 240 W. Buyers with ultrabooks or non-Dell systems should look elsewhere.

Questions about this item

Does the adapter ship with the mains lead or only the brick and 7.4 mm × 5.0 mm tip?

The listing describes the power cord as part of the unit, so the AC cable and the 7.4 mm × 5.0 mm connector are included; nothing extra is required for basic operation.

My laptop originally came with a 180 W unit — will the 240 W 19.5 V 12.3 A model work safely?

Yes — the specifications state 19.5 V 12.3 A 240 W and note compatibility with 19.5 V 9.23 A 180 W, so the higher-wattage adapter will run the same systems without issue.

What does the 240 W rating mean when the charger is plugged into a Precision 7710 or Alienware 17 R4?

It means the adapter can deliver up to 19.5 V at 12.3 A, giving the laptop full charging speed and enough headroom for heavy workloads while the built-in protections guard against over-current, over-voltage and overheating.
