  • 240 W output powers demanding Dell Alienware and Precision laptops
  • 5 V 12.3 A DC delivery matches original PA-9E specifications
  • 4 mm x 5.0 mm connector fits listed models without adapters
  • 100 V to 240 V AC input works worldwide on 50 Hz to 60 Hz mains
  • circuit, over-current, over-voltage and over-heating protection keeps charging safe

240W Dell Alienware & Precision Charger

This 240W AC adapter supplies 19.5V at 12.3A through a 7.4mm by 5.0mm barrel connector. It is built for Dell Alienware M17x, M18x and X51 models plus Precision M6400 through M6800 mobile workstations. The unit accepts 100 to 240V input at 50 to 60Hz for worldwide use. A power cord is included in the box.

Replaces PA-9E and GA240PE1-00 family units

The adapter matches part numbers such as PA-9E, GA240PE1-00, ADP-240AB and numerous Dell service tags including 330-4128 and 450-18931. It restores full charging speed when the original brick has failed or been lost. The upgrade is worthwhile only if the laptop requires the full 240W rating; lower-wattage machines will not draw more current than they need.

Plug-in replacement with built-in protections

Installation is a simple swap: disconnect the old brick, connect the new connector and attach the supplied mains cord. Short-circuit, over-current, over-voltage and over-temperature circuits keep the charger cool and safe during the entire charge cycle. The only common issue is attempting to use the 7.4mm tip on a Dell model that requires a different barrel size.

Questions about this item

What connector size does the myVolts Slim 240W adapter use to fit the Dell Alienware M17x R3?

The adapter uses a 7.4 mm by 5.0 mm barrel connector that matches the Dell Alienware M17x R3 power input.

How do I install the myVolts Slim 240W adapter on a Dell Precision M6600, and what step is often missed?

Plug the AC cord into the adapter first, then connect the 7.4 mm by 5.0 mm tip firmly into the laptop until it clicks; the click is the step many skip.

When will the myVolts Slim 240W adapter or its power cord need replacement on a Dell Alienware M18x R2?

Replace the unit if the 19.5 V 12.3 A output becomes unstable, the barrel tip wears loose, or the AC cord shows fraying after extended use.
