Dell 50W AC adapter for select laptops

This 12V 4.16A power supply replaces the Dell PA-1051-0 unit. It delivers 50W of continuous output for compatible Dell notebooks. The adapter is manufactured by Liteon and ships in new condition with a black housing. Part numbers 5KTNX and 05KTNX are referenced on the label.

Verify voltage and connector before ordering

Your laptop must require exactly 12V input and accept the barrel connector used by this model. Check the original adapter label for a 50W rating and 4.16A current specification. Confirm the Dell part number matches PA-1051-0, 5KTNX or CN-05KTNX. Using an incorrect voltage or tip can damage the system.

Fits as a direct replacement for the original

The unit plugs into a standard AC mains outlet and connects to the laptop power jack. It frees you from a lost or faulty factory adapter without needing a docking station. No extra cables or configuration are required. Buyers needing higher wattage for larger workstations should look elsewhere.
