DC Jack to USB-C PD Cable

This Fervit cable converts a 3.5x1.35mm DC barrel input into a USB-C power delivery output rated for 65W maximum. It accepts DC input from 15V to 20V and supplies variable output profiles including 5V/2A, 9V/3A and 20V/3.25A. The adapter suits users who want to power USB-C laptops, tablets or phones from an existing barrel-type charger.

Upgrade from fixed-voltage barrel supply

The cable replaces a single-voltage barrel charger by adding PD negotiation so one power source can serve multiple USB-C devices. The jump is worth it when you already own a 15V-20V DC adapter and need flexible 5V, 9V or 20V output without buying a new multi-port charger. It does not suit buyers who need a standalone wall plug or a higher wattage than 65W.

65W headroom for mainstream USB-C gear

At 65W maximum the cable comfortably handles ultraportable laptops, tablets and phones that charge over PD, QC2.0, QC3.0, DCP, PE+1.1, PE2.0, FCP, AFC, SFCP, SCP and standard USB PD. It runs out for larger laptops or workstations that demand more than 65W, and it cannot supply power to devices that require a different barrel size or a pure DC pass-through without PD handshake.

Questions about this item

What size DC jack does this cable plug into?

The cable has a 3.5 x 1.35 mm DC jack input that fits power adapters with that exact barrel size.

How do I connect the cable so the laptop actually charges?

Plug the DC jack into a 15 V to 20 V source, then connect the USB-C plug to the device; the cable negotiates PD automatically.

When should I replace this cable?

Replace it if the USB-C connector feels loose, the barrel jack wobbles, or the cable no longer delivers the rated 65 W output.
