45W Dell laptop charger
This 45W AC adapter delivers 19.5V at 2.31A for a wide range of Dell Inspiron, Latitude, Vostro, XPS and OptiPlex laptops. It replaces original Dell part numbers such as D0KFY, X9RG3, JHJX0, LA45NM131 and HA45NM140. The unit accepts 100-240V 50/60Hz input for worldwide use. It is a new, CE, FCC and RoHS certified replacement charger.
4.5mm x 3.0mm barrel connector
The charger uses a 4.5mm outer and 3.0mm inner diameter barrel tip that must match the laptop's DC jack exactly. Polarity and voltage are fixed at 19.5V, so the tip size is the single specification that decides compatibility. Verify the connector dimensions against the original adapter before purchase.
Fits slim ultrabooks and mainstream notebooks
The compact brick plugs directly into a standard IEC C7 figure-8 mains cord, freeing a desk socket compared to bulkier power supplies. It powers 11in, 12in, 13in, 14in, 15in and 17in Dell models across the 3000, 5000 and 7000 series without needing a separate voltage selector. Builders needing higher wattage for discrete graphics or docking stations should look elsewhere.
