Compatible Dell and Alienware Laptops

This 240W AC adapter replaces Dell 240W, 230W and 180W chargers for Alienware M18, M18X R2, x15 R1, x15 R2, x16 R1, x16 R2, x17 R1, x17 R2 and Alienware X51 R2 models. It delivers 19.5V at 12.3A through a 7.4mm barrel connector with a centre pin. It does not replace 280W, 300W or 330W adapters, so buyers needing higher-wattage units must look elsewhere.

Thermal Safety and Power Delivery

The adapter includes overload protection, short-circuit protection and over-voltage, over-current and over-temperature safeguards. A durable case resists extreme conditions and seals out water and humidity while maintaining high power efficiency for a steady 240W output. Two six-foot cords — a UL-listed three-prong AC lead and a DC lead — give ample reach without extension cables.

Bundled Cord Length and Safety Features

The extra-long AC and DC cables together provide extended placement flexibility around a desk or workstation. Built-in smart safety circuits guard the laptop and adapter from electrical faults during normal operation. No additional software or accessories are included beyond the power cords and the adapter unit itself.

Questions about this item

How do I install the 7.4 mm center-pin plug on my Alienware x16 R1?

Align the center pin with the laptop jack, push straight in until it clicks, then connect the 6 ft AC cord to the wall outlet and the 6 ft DC cord to the adapter brick.

What maintenance will the 240 W 19.5 V 12.3 A adapter need later?

Inspect the 6 ft AC and DC cords for wear every few months; keep vents clear of dust and replace the unit if the plug tip or cable insulation shows damage.

What limit appears first when the 240 W brick runs continuously at full load?

The over-temperature protection engages before the 240 W output can be exceeded, shutting the adapter down until it cools.
