57J49 D5G6M 331-9319 - 7.4mm to 4.5mm Tip Converter DC Power Dongle Adapter Cable for XPS Inspiron Latitude Precision

Description

This DC power dongle adapter converts a 7.4mm x 5.0mm barrel-tip AC adapter to the smaller 4.5mm x 3.0mm connector used on many laptop systems. It is commonly used with 45W, 65W, 90W, and 130W AC adapters that have the larger 7.4mm connector and need to connect to a laptop with a 4.5mm DC-in port.

Important: This converter requires an AC adapter with a 7.4mm x 5.0mm barrel tip. It does not convert USB-C adapters and does not change the wattage or voltage of the original charger. Always use an adapter with the correct wattage required by your laptop.
