USB-C Female to Dell 7.4x5.0mm DC Converter

This adapter cable converts a USB-C Power Delivery source into a Dell 7.4x5.0mm barrel connection. It supports 18.5V to 20V output at up to 3A for laptops rated at 65W or below. The female USB-C input accepts a compatible PD charger. The male DC tip plugs directly into the laptop power jack.

Suits Dell 7.4mm barrel owners with PD chargers

Owners of listed Dell Inspiron, Latitude, and Alienware models using a 7.4x5.0mm tip can power their device from a 65W USB-C PD charger. Buyers whose laptop requires a higher wattage input or a different barrel diameter should look at another solution. The cable does not work with USB-C chargers lacking Power Delivery support.

65W PD compatibility at 18.5V-20V 3A

The converter operates with USB-C PD wall chargers rated at 65W or above, delivering 18.5V to 20V at 3A maximum current. This specific voltage and current window decides whether the adapter will safely power a given Dell laptop. Confirm the laptop's original charger matches these output values before use.
