USB-C PD Trigger Cable for Laptops

This SMUGDESK cable converts a USB-C Power Delivery source into a 20 V DC output for laptops. A built-in PD trigger chip requests the higher voltage from compatible power banks or chargers. The cable delivers up to 65 W to devices that accept a 5.5 mm barrel connector. It is intended for users who want to power a laptop from a portable USB-C supply.

Check Your Power Source and Laptop Port

Before ordering, confirm that your USB-C charger or power bank explicitly supports 20 V Power Delivery output. The laptop must use a 5.5 mm DC input with either a 2.5 mm or 2.1 mm centre pin. Devices that require a different voltage or a proprietary connector will not work with this cable.

Interchangeable Tips Expand Compatibility

The package includes both 5.5×2.5 mm and 5.5×2.1 mm plug tips, covering the two most common barrel sizes. Swapping the tip lets a single cable serve multiple laptops or monitors without carrying separate adapters. No drivers or software are involved; the cable operates purely as a passive power converter once the PD handshake succeeds.

Questions about this item

What plugs are included and does the cable need a separate charger?

The cable ships with interchangeable 5.5×2.5mm and 5.5×2.1mm DC plugs. You must supply your own USB-C PD charger or power bank that can deliver 20V.

How do I know which of the two DC plugs fits my laptop?

Check the laptop’s original power jack: 5.5×2.5mm is the larger centre pin, 5.5×2.1mm the smaller. Match the plug to that measurement.

What does the 65W PD trigger rating mean when I connect the cable?

The built-in chip negotiates a fixed 20V output from the USB-C source, allowing up to 65W of power delivery to the laptop’s DC port.
