Fervit USB-C to DC 5.5x2.5mm PD Cable

This cable adapts a 65W USB-C charger to power laptops that use a 5.5mm by 2.5mm DC barrel jack requiring 18-20V. It targets owners of older or proprietary laptops who want to replace a bulky original brick with a modern GaN charger. The built-in PD trigger negotiates the correct voltage automatically. It is not for devices that only charge at 5V or need more than 65W.

Thermals noise and power draw

The cable itself generates negligible heat and no audible noise during normal charging. Power draw at the laptop end matches the charger output up to 65W at 18-20V. Efficiency depends on the charger used; the cable adds no active components beyond the PD trigger chip. It does not support 5V output, so low-power USB devices cannot be run from this adapter.

Replaces proprietary barrel charger

This cable replaces a lost or damaged proprietary AC adapter for laptops with a 5.5x2.5mm 18-20V input. The jump is worth it when you already carry a 65W USB-C charger for other gear and want one less brick in your bag. It will not work if the laptop draws more than 65W or requires a voltage outside the 18-20V range.

Questions about this item

How do I connect the Fervit cable so the built-in PD trigger activates correctly?

Plug a 65 W USB-C charger into the female Type-C end, then insert the 5.5 × 2.5 mm DC plug into the laptop; the trigger negotiates 18-20 V automatically.

What part of this adapter is most likely to wear out first with daily plugging and unplugging?

The 5.5 × 2.5 mm DC barrel connector and the USB-C female socket see the most mechanical stress and will eventually loosen or lose contact.

At what power level does the cable stop delivering full output during a long charging session?

If the attached USB-C charger cannot sustain more than 65 W, the output will drop once the laptop demands more than that limit.
