What this charger replaces

This 45W AC adapter supplies 19.5V at 2.31A through a 4.5mm outer and 3.0mm inner barrel connector. It operates on 100-240V input and matches Dell part numbers including CC0DT, X9RG3, 492-BBOF and PA-1450-66D1. The unit is sold new.

Who should buy it and who should not

It fits a wide range of Dell Inspiron 11, 13, 14, 15, 17, 20 and 24 models across 3000, 5000 and 7000 series, plus select Vostro, Latitude and XPS laptops listed in the compatibility data. Buyers whose Dell requires a different connector size, a higher wattage output or a USB-C power input should look elsewhere.

The specification that decides fit

The barrel connector measures 4.5mm outside diameter and 3.0mm inside diameter with 19.5V 2.31A output; if the original Dell charger does not share those exact electrical and physical parameters this adapter will not work.
