65W Dell AC Adapter with Dual Round Tips

This 65W adapter delivers 19.5V at 3.34A for Dell laptops that use a round connector. It includes both 4.5mm and 7.4mm tips to fit a wide range of Inspiron and Latitude models. The unit accepts 100V to 240V input at 50-60Hz for worldwide use.

Capacity and Headroom: 65W Output for Mainstream

The 65W rating comfortably powers mainstream Dell laptops such as the Inspiron 3520 3530 5400 and Latitude 5490 5500 7490 during typical workloads and charging. It will run out of headroom on systems that draw more than 65W under load, such as larger 17-inch configurations or workstation-class machines requiring 90W or 130W bricks.

Replaces 45W and 65W Dell Round-Tip Bricks

This adapter replaces original Dell parts including LA65NM130 HA65NM130 DA65NM111-00 and 45W units like ADP-45XD BA LA45NM140. The jump is worth it when a 45W charger cannot sustain performance or charge while the laptop is in use. It is not for buyers who need USB-C Power Delivery or barrel tips other than the two round sizes supplied.

Questions about this item

Will this 65W adapter with the 4.5mm and 7.4mm tips charge my older Dell Latitude E6420 that uses a round connector?

Yes, the adapter includes both 4.5mm and 7.4mm round tips and lists the Latitude E6420 among its compatible models, so it will charge that laptop.

How can I confirm the adapter is delivering the correct 19.5V output after I plug it in?

The LED on the connector tip will light up when the adapter is supplying 19.5V at 3.34A, and the laptop’s battery icon should immediately show a charging state.

Does the box contain both the 4.5mm and 7.4mm tips, or must I buy one separately?

Both round tips — 4.5mm and 7.4mm — are integrated on the same cable, so nothing extra is required to fit either Dell connector size.
