WAWEIS 240 W AC Adapter for Dell Alienware m17 R3

This WAWEIS 240 W AC adapter is a new replacement charger built specifically for the Dell Alienware m17 R3 laptop. It delivers the same 240 W output as the original DA240PM190 and HA240PM190 power supplies. The unit includes integrated safety features such as over-current, over-voltage, short-circuit and total power protection. A 10 ft mains cable is supplied for flexible desk placement.

Before ordering check your existing setup

Confirm that your laptop is the Alienware m17 R3 and that the original charger carries the DA240PM190 or HA240PM190 part number. Verify that the DC connector tip matches the one on your current adapter. Ensure your mains supply operates between 100 and 240 VAC at 50 or 60 Hz, which covers standard household outlets worldwide. The adapter carries FCC, CE and RoHS certifications for regulatory compliance.

Ideal for owners needing a direct replacement

This adapter suits Alienware m17 R3 users who have lost, damaged or worn out their original 240 W charger and want a certified, plug-compatible unit with a long cable. It is not for owners of other Alienware models or Dell laptops that require a different wattage or connector type. Buyers needing a multi-voltage travel adapter with interchangeable tips should look elsewhere. Those seeking a higher-wattage unit for future-proofing will not find that capability here.

Questions about this item

Does the 240 W adapter include the mains cable or do I need to buy one separately?

The package contains the adapter and a total 10 ft power cord, so no separate cable is required.

There are two Dell part numbers listed — DA240PM190 and HA240PM190 — which one should I match to my m17 R3?

The adapter is 100 % compatible with both part numbers, so either reference on your original charger will work.

What does the 240 W rating mean when the adapter is running on 100 V mains instead of 240 V?

World wide input voltage 100-240 VAC 50/60 Hz delivers the full 240 W output across the entire range.
