180 W 19.5 V AC Adapter for Dell G Series

This 180 W AC adapter supplies 19.5 V at 9.23 A through a 7.4 x 5.0 mm barrel connector and is built for Dell G7, G5 and G3 laptops including 15-inch and 17-inch models such as the 7500, 7588, 7590, 7700, 7790, 5587, 5590, 3500 and 3579. It also matches Dell Precision 7510, 7520, 7530, M4600, M4700, M4800, M6600 and Inspiron One 2320 and 2350 systems. The unit accepts 100-240 V input at 50-60 Hz and includes over-voltage, over-current and short-circuit protection with UL listing.

Replacing a Lost or Failing 180 W Charger

If the original Dell 180 W adapter (part numbers DA180PM111, FA180PM111, ADP-180MB B, NDFTY, 450-AGCU, 0N7MWW or N7MWW) is missing, damaged or no longer holds a stable output, this unit restores full charging capability without change to the laptop. The jump is worth it when the old brick shows intermittent charging, overheats or the cable frays near the connector. It also serves as a spare for home, office or travel so the primary adapter can stay docked.

180 W Output with 130 W Backward Compatibility

At 180 W the adapter comfortably powers high-performance Dell G-series and Precision mobile workstations under full load while charging the battery. It also supports systems that originally shipped with a 130 W 19.5 V 6.7 A brick, delivering the same voltage with higher current headroom. The adapter will not suit laptops that require a different connector size, a USB-C PD source or a lower voltage rail.
