180W Replacement Adapter for Dell Precision

This 180W AC adapter replaces the original charger for Dell Precision 7520, Alienware 15 R4, Alienware 17 R5, G7 15 7588, G5 15 5587 and Alienware M15 laptops. It delivers the same power specification as the factory unit and carries FCC, CE and RoHS certification. The package includes a 10 ft power cord for flexible placement. Builders maintaining or repairing these specific models will find a direct-fit solution.

Capacity and headroom: 180W output with worldwide

The adapter supplies 180W of continuous power, matching the requirement of the listed Precision and Alienware systems. Worldwide input voltage of 100-240VAC at 50/60Hz allows use across different mains standards without a separate converter. Integrated protection covers over-current, over-voltage, short-circuit and total power events. It is not suitable for laptops that demand a higher wattage brick or a proprietary connector not listed above.

Build integration: direct barrel connection

The barrel plug fits the charging port on each named Dell and Alienware model without adapters or modifications. A 10 ft mains cable reaches distant wall outlets, reducing the need for extension leads in a desk or bench setup. The brick runs on standard AC mains and requires no additional drivers, firmware or software configuration. Systems using USB-C Power Delivery or a different barrel size cannot use this unit.

Questions about this item

Will the 180W adapter charge my Precision 7520 while I keep the original Dell dock connected?

The adapter delivers 180W at 100-240VAC 50/60Hz, matching the Precision 7520 factory requirement, so it powers the laptop and any dock drawing from the same barrel port.

How can I confirm the 180W charger is operating correctly once plugged in?

The laptop battery icon should show charging, the adapter LED (if present) stays solid, and the unit remains only warm thanks to over-current, over-voltage, short-circuit and over-temperature protections.

Does the box include both the 10 ft mains cord and the DC barrel tip for Alienware 17 R5, or must I buy the cord separately?

The package ships with the 180W brick, a detachable 10 ft AC mains cord and the fixed DC barrel connector already fitted for the listed Alienware and Dell models.
