What this cable does

The Fervit 100W USB-C to DC 4.5×3.0mm cable converts a USB-C Power Delivery source into a barrel jack output for laptops and other devices. It supports up to 100W at 20V/5A and also works with 65W chargers. The woven braid sleeve adds durability and tangle resistance. Total length is 18cm including connectors.

Check before ordering

Your USB-C charger or power bank must deliver DC 15V–20V input and support the required Power Delivery profile for 20V/5A output. Verify that your laptop or device uses a 4.5×3.0mm DC jack and accepts 20V, 9V or 5V at the stated currents. Using an incompatible voltage or current rating can damage the connected equipment.

Who this suits

This cable suits users who want to power a barrel-jack laptop from a high-power USB-C PD charger or power bank. It is not for devices that require a different barrel size or a voltage outside the 5V, 9V, 20V range. Buyers needing a longer cable or a right-angle connector should look at something else.

Questions about this item

Does the 18 cm cable include both connectors or do I need a separate USB-C power brick?

The 18 cm length covers the whole assembly including the USB-C plug and the 4.5×3.0 mm DC jack; you must supply a USB-C charger or power bank that can deliver up to 100 W at 20 V 5 A.

My laptop needs 65 W at 20 V — will this cable handle that or should I choose a different one?

The cable supports 5 V 1.5 A, 9 V 1.5 A and 20 V 5 A outputs, so a 65 W 20 V laptop is within the 100 W maximum and will work provided the charger also provides 20 V.

What does the 100 W rating mean when I plug this into my MacBook Pro 2020?

It means the cable can pass up to 20 V 5 A from a compatible 100 W USB-C charger to the DC jack, letting the MacBook draw its required power up to 100 W while in use.
