What this adapter is and who it powers

This 45W AC adapter supplies 19.5V at 2.31A to compatible Dell laptops. It replaces original chargers for Inspiron 3000, 5000 and 7000 series models in 11, 13, 14, 15 and 17 inch sizes. It also fits select XPS, Latitude, Vostro and OptiPlex units listed in the compatibility data.

Connector fit is the deciding spec

The barrel plug measures 4.5mm outer diameter by 3.0mm inner diameter. Polarity and voltage must match the laptop’s original supply exactly. Check the tip on your existing charger against the product image before ordering.
