A re-programmable USB Type-C Power Delivery (PD) cable that converts any PD-capable USB-C power adapter into a configurable DC barrel jack output. Programme the built-in PD sink negotiation chip to request 5 V, 7 V, 9 V, 10 V, 12 V, 15 V, or 20 V at up to 2 A — replacing the need for multiple wall adapters with different voltage outputs.
The cable terminates in a 5.5 mm outer / 2.5 mm inner barrel jack that also fits 2.1 mm sockets. One metre long with a Velcro cable tie included. Reprogramming is done via the included programmer dongle and Windows software.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- DC barrel jack
- A round power connector commonly used for low-voltage DC power supplies, often described by its outer and inner diameters such as 5.5 x 2.1 mm. Matching the barrel size and polarity is important so the plug physically fits and powers the device correctly.
- Type-C
- USB Type-C (USB-C) is a small, reversible USB connector used for charging, power, and data transfer on many modern devices. A Type-C port or plug indicates the cable and charger connection needed to power, charge, or communicate with a device.
- USB Type-C
- USB Type-C is a small, reversible USB connector used for power, data and sometimes video on many modern devices. The connector itself does not guarantee a particular speed or voltage, so check the supported USB version, data rate and whether it carries more than 5V via USB Power Delivery.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
