Target laptops

This 45W USB-C AC adapter fits Dell XPS 13 7390 P82G and P103G models plus the Inspiron 7490. It replaces the original charger for owners who need a spare or replacement unit.

Thermal and protection profile

The adapter operates from a 100-240V 50-60Hz input and includes over-voltage, over-current and short-circuit output protection. Its compact design keeps heat low during normal charging sessions.

Continuous output provides 5V, 9V or 15V at 3A and 20V at 2.25A for the full 45W rating. The brick maintains these levels without the throttling seen in lower-rated travel chargers.

Questions about this item

How do I install the 45W USB-C adapter on my Dell XPS 13 7390, and what step do people often miss?

Plug the AC cord into a 100-240V 50-60Hz outlet, then connect the USB-C plug to the laptop; the step often missed is verifying the laptop draws 20V 2.25A for full 45W charging.

What maintenance or replacement will this 45W USB-C adapter need later?

The adapter has no user-serviceable parts; if the USB-C cable frays or the brick shows overheating, replace the whole unit after the one-year warranty period.

What limit appears first on this 45W USB-C adapter under sustained load?

The 45W output ceiling (20V 2.25A) is the first limit; sustained loads above this trigger OCP or OVP protection and shut the adapter down.
