45 W AC Adapter for Dell Notebooks

This 45 W AC adapter supplies 20 V DC at 2.25 A to compatible Dell XPS and Latitude notebooks. It accepts 120 V AC or 230 V DC input and includes a 3.28 ft power cord. The unit replaces OEM part numbers such as 689C4, LA45NM150 and ADP-30CD BA. It is sold new and ready for immediate use.

Check Connector and Voltage Before Ordering

Verify that your notebook requires a 20 V DC input rated at 45 W or lower and that the barrel connector matches the original adapter. Confirm the model appears in the compatibility list covering XPS 12 9250 and Latitude 11 5175, 11 5179, 12 7275 and 13 7370. Using an adapter with a different voltage or tip can prevent charging or cause damage.

Steady 45 W Output Under Continuous Load

The adapter is rated to deliver its full 45 W continuously at 20 V DC and 2.25 A without time-limited boost behaviour. Thermal design maintains stable voltage during extended charging sessions or while the notebook runs demanding workloads. No higher peak power or dynamic voltage steps are specified beyond the stated maximums.
