45 W AC Adapter for Dell Notebooks and Chromebooks

This 45 W AC adapter from Battery Technology Inc. replaces the original charger for a wide range of Dell notebooks and Chromebooks. It is intended for users who need a direct replacement or a spare power supply for the models listed in the compatibility data. The unit is supplied new and carries a 24 month limited warranty from the manufacturer.

Practical limits of a 45 W barrel connector supply

A 45 W adapter delivers a fixed maximum output, so it cannot charge systems that require a higher wattage input or negotiate power delivery profiles beyond its rating. The barrel connector provides a single voltage rail, meaning it does not support variable voltage negotiation or data communication over the cable. Users must verify that their device accepts this specific connector size and polarity before use.

Check your existing setup before ordering

Confirm that your Dell model appears in the supported list, which includes various Latitude, Inspiron, XPS, Chromebook, Venue and Rugged Extreme units. Verify that the original charger part number matches PA45W16-CA and that the connector tip fits your device's charging port. This adapter is not suitable for laptops that require USB-C Power Delivery or a higher wattage power source.
