Adafruit 240W 19.5V laptop charger

This new charger delivers 19.5 volts at 12.3 amps for a maximum output of 240 watts. It operates on a universal 100 to 240 volt input at 50 to 60 hertz. The connector tip measures 7.4 millimetres by 5.0 millimetres. It replaces a wide range of original Dell part numbers including FWCRC and PA-9E.

Suits Alienware, Precision and G-series owners

Buyers with Dell Alienware 13, 15, 17, M11X, M14X, M15X, M17X or M18X models can use this adapter. It also fits Precision mobile workstations such as the 7510, 7520, 7530, 7710, 7720, 7730 and M6500 through M6800. G-series users with G3, G5 or G7 15-inch and 17-inch systems are covered. Anyone needing a different connector size or a lower maximum wattage should look elsewhere.

7.4 mm by 5.0 mm barrel connector decides fit

The single specification that determines compatibility is the 7.4 millimetre outer diameter and 5.0 millimetre inner diameter barrel plug. If the laptop requires this exact tip geometry the charger will seat correctly. If the port differs in either dimension the unit cannot be used.

Questions about this item

Does the 7.4 mm by 5.0 mm barrel connector fit my Dell Alienware 17 R3?

Yes, the 7.4 mm by 5.0 mm tip matches the charging port on Alienware 17 R1 through R5 models.

What is the common mistake when plugging this 240 W adapter into a Dell Precision 7710?

Users often insert the 7.4 mm plug at an angle; push it straight in until the barrel seats fully so the centre pin makes contact.

When should I replace the 19.5 V 12.3 A power brick for my Dell G7 7588?

Replace it if the brick becomes unusually hot, the cable frays near the connector, or the laptop stops charging while the LED on the adapter stays lit.
