Genuine Dell 45W AC Adapter

This new genuine Dell AC adapter supplies 19.5V at 2.31A through a 4.5mm barrel tip. It replaces original part numbers including 0KXTTW and LA45NM140 for compatible Inspiron, Latitude and Vostro laptops. The unit ships with a mains power cord in non-retail packaging.

45W output limit and fixed tip

The adapter delivers a maximum of 45 watts, so it cannot charge laptops that require a higher input rating. The 4.5mm barrel connector is not interchangeable; models that use USB-C charging or a different barrel diameter will not fit. Always verify the voltage and tip size against the original charger before use.

Direct plug-in replacement

Installation is limited to connecting the mains cord to the adapter and the barrel plug to the laptop power socket. No drivers or configuration are required. The most common issue is purchasing the wrong tip size or wattage for a specific model, which prevents charging altogether.
