Purpose and compatibility

This USB-C female to 7.4x5.0mm DC tip converter cable lets you power compatible Dell laptops from a USB-C Power Delivery charger. It supports models rated at 65W or below that use the 7.4mm by 5.0mm barrel connector, covering a wide range of Inspiron, Latitude and Alienware systems.

Power delivery under load

The adapter handles 18.5V to 20V at up to 3A, matching the output profile of a 65W USB-C PD source. It passes the negotiated voltage directly to the laptop’s DC input, so sustained charging performance depends on the charger maintaining its PD contract without thermal throttling.

Build and daily use

A male 7.4x5.0mm barrel plug mates with the laptop while a female USB-C port accepts the charger cable, creating a straight-through connection with no extra bulk. The black housing is rated as brand new and plugs in without tools, making it a practical spare for travel or a permanent desk setup.

Questions about this item

Does the cable or the Dell 7.4x5.0mm tip get warm when I run a 65W charger all day?

The converter is rated for 18.5V-20V at 3A, matching the 65W PD profile, so heat stays low during continuous use.

What charger must I already own to power a Dell laptop through this converter?

You need a USB-C PD wall charger that can deliver 65W or more at 18.5V-20V; the cable itself only passes that power through.

Will the 7.4x5.0mm tip fit the Dell Latitude E6440 and E6230 I still use?

Yes — both models are listed among the compatible Dell laptops that use the 7.4x5.0mm DC barrel connector.
