USB-C to 20 V DC cable for 4.0×1.7 mm laptops

This 1.5 m adapter cable converts a USB 3.1 Type-C source into a 20 V, 4.0×1.7 mm barrel output. It is intended for users who want to power compatible laptops, notebooks, routers or similar 20 V devices from a single USB-C charger or power bank. The black plastic construction keeps the cable light and easy to pack.

Requires a 20 V PD source.

Suitable for owners of devices that accept 20 V via a 4.0×1.7 mm jack and who already have a USB-C supply capable of delivering 20 V. Buyers whose charger or power bank tops out at lower voltages cannot use this cable. It also does not suit devices with a different barrel diameter or polarity.

4.0×1.7 mm barrel plug at 20 V output

The connector measures 4.0 mm outer diameter and 1.7 mm inner diameter and delivers a fixed 20 V from the USB-C end. Verify that the target device matches this exact plug size and voltage before purchase.

Questions about this item

What connectors and cable are included and is a charger supplied?

The package contains one 1.5 m USB-C to 4.0×1.7 mm DC cable; a USB-C charger or power bank is not included and must be purchased separately.

How do I know if my USB-C charger works with this 20 V cable?

Your USB-C charger or power bank must support a 20 V output profile; check its specification label or manual for a 20 V PDO before buying.

What does the 20 V rating mean when I plug this into my laptop?

The cable delivers a fixed 20 V from a compatible USB-C source to the 4.0×1.7 mm barrel jack, so the connected device receives 20 V directly.
