What this adapter replaces

This 65-watt AC adapter delivers 19.5 volts at 3.34 amps and matches the octagonal 7.4 mm by 5.0 mm tip used by several Dell Inspiron and XPS models. It is a new replacement unit for owners of listed laptops whose original charger has failed or been lost.

The specification that decides fit

The critical detail is the 7.4 mm by 5.0 mm octagonal connector with a centre pin; only laptops requiring that exact tip will work. The unit accepts 100 to 240 volt input at 50 to 60 hertz, so it operates worldwide with the appropriate plug.

Installation and common issues

Plug the detachable mains cord into the adapter, connect the tip to the laptop, and the power LED confirms output. The most frequent problem is ordering this adapter for a Dell model that uses a different barrel size or a USB-C charging port, which this unit does not support.

How does the 7.4 mm × 5.0 mm octagonal tip connect to the laptop?

The connector uses an octagonal barrel with a centre pin that fits Dell Inspiron 1318, 1440, 1530, 1545, 1546, 1551, 1557, 1750 and XPS M1330 charging ports.

What does the 100-240V 50-60Hz input allow for worldwide use?
