240 W AC adapter for Dell G15 Precision Alienware

This 240 W replacement adapter supplies 19.5 V at 12.3 A and fits Dell G15 5510 5511 5515 5520 5525 G16 7620 Precision 15 7560 and Alienware m15 R1 R2 R3 R5 R6 R7 m17 R1 R2 R5 models. It replaces Dell 180 W 230 W 240 W chargers and uses a 7.4 mm tip with centre pin. Not suitable for systems that require a 280 W 300 W or 330 W unit or a 9.0 mm tip.

Thermals noise and power draw

The adapter accepts 100 to 240 V AC at 50 to 60 Hz for worldwide use and delivers up to 240 W maximum output. Internal safety circuits filter voltage spikes and limit output to protect the laptop. A rugged sealed case resists moisture and humidity while maintaining efficient continuous power delivery.

7.4 mm centre-pin tip compatibility

The plug tip measures 7.4 by 5.0 mm and includes a centre pin; it is not the larger 9.0 by 6.2 mm variant. Two six-foot cords are provided: a UL listed three-prong AC cord and a DC cord to the laptop. This combination gives extended reach without needing an extension lead.

Questions about this item

How do I install the 7.4mm tip adapter on my Dell G15 5515, and what step is often missed?

Plug the 7.4 x 5.0 mm tip firmly into the laptop's charging port until the center pin seats, then connect the 6 ft DC cord to the brick and the 6 ft AC cord to a 100-240V outlet; the step often missed is verifying the tip size is 7.4mm not 9.0mm before inserting.

What maintenance or replacement will the 240W adapter need later?

The UL-listed 6 ft AC cord and 6 ft DC cord are the only user-serviceable parts; replace either cord if the insulation cracks or the connector loosens, otherwise the sealed 19.5V 12.3A brick requires no internal maintenance.

What limit appears first when the 240W charger runs under sustained load?

The 240W maximum output at 19.5V 12.3A is the first limit; it replaces 180W and 230W units but will not support systems needing 280W, 300W or 330W, so sustained draws above 240W will trip the protection.
