  • 45W output powers compatible Dell laptops efficiently
  • 5V 2.31A matches original Dell charger specifications

  • 100-240V input works worldwide without voltage converter

Power Rating & Connector

This 45W AC adapter delivers 19.5V at 2.31A through a 4.5×3.0mm barrel connector. It accepts 100-240V input at 50-60Hz for worldwide use. The unit replaces Dell part numbers including DA45NM131, LA45NM140 and HA45NM140. It is built for Dell laptops that require this exact voltage, current and tip size.

Replacement Scope

The adapter covers Dell 11, 13, 14, 15 and 17 series models such as Inspiron 3000, 5000 and 7000 lines, plus Latitude 12 and 13, Vostro 14 and 15, and XPS 13 variants including 9333, 9343 and 9350. It matches OEM part numbers like 312-1307, 332-1827 and 450-1846. Buyers needing a higher-wattage supply for larger workstations or gaming laptops should look elsewhere.

Input Limits

The 100-240V AC input range handles mains voltages found in most countries without a separate transformer. Output is fixed at 19.5V 2.31A, so the charger cannot power devices that demand a different voltage or higher current. The barrel tip measures 4.5mm outer diameter and 3.0mm inner diameter; laptops with USB-C charging or proprietary Dell connectors will not fit.

Questions about this item

Will the 4.5 mm × 3.0 mm barrel connector fit my Dell XPS 13 9350?

The connector has a 4.5 mm outer diameter and 3.0 mm inner diameter, matching the Dell 45 W chargers used on the XPS 13 9350.

How do I install the adapter, and what step do people often miss?

Plug the AC cord into the brick, insert the barrel tip firmly until it seats, then connect the mains plug; the step often missed is pushing the tip in until it clicks.

When will I need to replace the AC cable or the adapter itself?

Replace the detachable AC cord if the insulation frays or the plug loosens; replace the whole adapter if output drops below 19.5 V or the brick overheats.
