240W laptop AC adapter

The Blueskysea SLRIOYS-240W is a 240W laptop AC adapter delivering 19.5V at 12.3A. It accepts a universal 100-240V input at 50-60Hz. The unit uses a 7.4mm by 5.0mm barrel connector tip and includes three plugs. It is sold new.

Suits Dell Precision and Alienware owners

This adapter fits owners of listed Dell Precision, Alienware, G3, G5 and G7 models needing a direct replacement. Buyers whose laptops require a different voltage, amperage or connector size should look at something else. Units needing a USB-C power source are not compatible with this barrel-tip design.

7.4mm x 5.0mm barrel connector

The single specification that decides fit is the 7.4mm by 5.0mm centre-positive barrel connector with three plugs. Only laptops specifying this exact tip geometry and the 19.5V 12.3A output will work correctly. Verify the tip dimensions against the original adapter before ordering.

Questions about this item

What connector tip size does the 240W adapter use?

The adapter uses a 7.4 mm by 5.0 mm connector tip, and the package includes three plug variants.

How do I install the adapter and which step is often missed?

Connect the AC cable to the power brick, plug the barrel tip firmly into the laptop until it clicks, then plug the mains lead into a 100-240V outlet; the step often missed is fully seating the barrel so the laptop recognises the 19.5V 12.3A supply.

When will the adapter or its cable need replacement?

Replace the unit if the barrel tip becomes loose, the cable shows exposed conductors, or the brick no longer delivers a steady 240W output.
