Fervit USB-C PD to DC 5.5x2.1mm Cable

This adapter cable converts a 65W USB-C Power Delivery charger into a 18-20V DC barrel output for compatible laptops. It targets users who want to replace a proprietary brick with a standard GaN charger. The built-in PD trigger negotiates the required voltage automatically. It does not suit laptops that charge only at 5V or require more than 65W.

Practical limits of the PD trigger

The cable only delivers 18V or 20V and explicitly does not support 5V output. The source charger must supply at least 65W and implement PD negotiation; a plain 5V USB-A port will not work. Polarity follows the 5.5mm outer, 2.1mm inner centre-positive convention, so reversed-pin laptops cannot use it. Maximum current is capped by the 65W ceiling of the trigger chip.

Installation notes and common pitfalls

Plug the USB-C male end of your charger into the female socket on the cable, then insert the DC plug into the laptop. Ensure the charger is rated 65W or higher; lower-power bricks will not trigger the 18-20V profile. A frequent error is using a charger that only offers fixed 5V or 9V profiles, which leaves the laptop unpowered. No drivers or configuration are required.

Questions about this item

What output voltage should I select for a laptop that needs 18-20V?

The cable outputs 18-20V DC from a 65W USB-C charger and does not support 5V, so match your laptop's required voltage within that range.

Will a 65W USB-C charger actually deliver 65W to my laptop through this cable?

Yes, when paired with a 65W USB-C charger the built-in PD trigger negotiates 20V at up to 65W, provided the charger can supply that power.

Does the 5.5x2.1mm DC plug fit every laptop barrel jack?

The cable uses a standard 5.5mm outer and 2.1mm inner diameter barrel connector; verify your laptop's jack matches these dimensions before use.
