Genuine Dell 130W slim adapter

This genuine Dell OEM PA-4E family AC power adapter delivers 130 watts at 19.5 volts DC through a 7.4mm barrel connector. It replaces the PA-13 unit and ships with a three-prong mains cord. The unit is brand new and built to Dell specifications for compatible notebooks and all-in-one desktops.

Check connector and voltage before ordering

Verify that your device uses a 7.4mm barrel jack and requires 19.5 volts DC at up to 6.70 amps. Confirm the model appears in the supported list covering Alienware, G Series, Inspiron, Latitude, OptiPlex, Precision, Studio, Vostro and XPS lines. The adapter accepts 100 to 240 volts AC at 50 or 60 hertz for worldwide use.

Runs cool and quiet in daily use

The slim brick operates silently with no moving parts and maintains low surface temperature during typical charging loads. Power draw from the wall matches the 130 watt output rating plus normal conversion losses. No fan noise or coil whine is expected under normal notebook charging conditions.
