240 W 19.5 V AC adapter for Dell G-series

This 240 W power supply delivers 19.5 V at 12.3 A through a 7.4 x 5.0 mm barrel connector with a centre pin. It fits Dell G3 15, G3 17, G5 15 and G7 15 models including the 3579, 3590, 3779, 5500, 5587, 5590, 7588 and 7590. The unit accepts 100 to 240 V input at 50 to 60 Hz for worldwide use. It replaces original Dell 180 W, 230 W and 240 W chargers.

7.4 x 5.0 mm plug and extra-long cables

The tip diameter is 7.4 x 5.0 mm, not the larger 9.0 x 6.2 mm variant, so verify the port before ordering. A UL-listed 3-prong AC cord measuring 6 ft and a matching 6 ft DC cord give a combined reach that removes the need for extension leads. The ruggedised case is sealed against moisture and high humidity for mobile durability. Internal protection filters input spikes and limits output voltage and current.

240 W ceiling for G3, G5 and G7 15- and 17-inch

The adapter comfortably powers the listed G3, G5 and G7 laptops while charging the battery whether the system is on or off. It does not replace 280 W, 300 W or 330 W Dell adapters, so machines that require those higher ratings are not supported. High power efficiency provides consistent output up to the 240 W maximum. Dimensions are 7.75 x 3.75 x 1.75 inches and weight is 46.20 oz.

Questions about this item

Will the 7.4 x 5.0 mm plug tip wear out and need replacement?

The ruggedized case and tight sealing protect the adapter from moisture and humidity, extending the life of the 7.4 x 5.0 mm connector under daily use.

What limits continuous output when running demanding workloads?

The adapter delivers a maximum of 240W at 19.5V and 12.3A; sustained loads above this rating will trip the internal over-current and over-voltage protection.

How much heat and noise does the brick produce during all-day operation?

High power efficiency reduces waste heat, and the sealed ruggedized case dissipates it silently without a fan during continuous 240W output.
