45W AC Adapter for Dell Inspiron

This 45-watt AC adapter supplies 19.5 volts at 2.31 amps to compatible Dell Inspiron laptops. It accepts a universal 100-240 volt input at 50-60 Hz for worldwide use. The unit is sold new and replaces original Dell chargers such as the DA45NM131 and LA45NM140. Buyers who need a higher-wattage power supply for larger workstations should look elsewhere.

4.5 mm Barrel Connector Fit

The connector tip measures 4.5 mm by 3.0 mm and is not compatible with the 7.4 mm by 5.0 mm barrel used on some other Dell models. It fits a wide range of Inspiron 11, 13, 14, 15 and 17 series plus select Latitude, Vostro and XPS 13 units. Verify the exact model number and tip size before ordering. Systems that require a USB-C power input cannot use this adapter.

Thermals and Power Draw

The adapter draws up to 1.3 amps from the mains while delivering its rated 45 watts to the laptop. Normal operation produces low heat and no audible fan noise because the unit is passively cooled. Keep ventilation slots unobstructed to maintain safe surface temperatures during extended charging sessions.
