Black USB-C to barrel DC cable with 5.5mm connector

Fervit

Fervit USB-C to DC 5.5×2.1mm 20V 140W PD cable

SKU CH-7GR4-WHB6D

Connects a USB-C PD charger of 135W or 140W to a laptop with a 5.5×2.1mm DC jack, delivering up to 140W at 20V

  • Charges laptops at 20V via USB-C PD
  • Supports 140W maximum power delivery
  • Works with 135W, 100W and 65W sources
  • Built-in PD trigger negotiates 20V automatically
  • Fits 5.5×2.1mm barrel charging ports

Purpose & Audience

This Fervit cable converts a USB-C PD source into a 5.5 × 2.1 mm DC barrel output at 20 V. It is built for owners of laptops or devices that charge through a 5.5 mm jack and want to use a high-power USB-C charger instead of the original brick. The integrated trigger chip requests 140 W from the source, enabling full-speed charging where the hardware allows.

Fit & Limits

It suits users who already have a 135 W or 140 W USB-C PD charger and need to power a 20 V barrel-input laptop. Buyers whose charger tops out at 100 W or below cannot reach the cable’s maximum output. Anyone whose device requires a different barrel diameter, voltage, or a proprietary connector should look at something else.

Deciding Spec

The cable delivers up to 140 W at 20 V and 7 A through a 5.5 mm DC plug, but only when paired with a 135 W or 140 W USB-C PD charger that supports the required power profile. Lower-power sources will fall back to 100 W, 65 W or less.

Questions about this item

What charger do I need to power this cable?

You need a USB-C charger rated at 135W or 140W that supports PD or QC 2.0/3.0 to deliver the full 20V 7A output.

Will it work with my older 65W or 100W USB-C charger?

Yes, the cable also supports 65W, 100W and 135W outputs, but the charger must still negotiate PD or QC 2.0/3.0 at 20V.

How can I confirm the cable is delivering 20V to my laptop?

The built-in PD emulator triggers a 20V 7A contract; check your laptop's charging indicator or power meter to see 20V negotiated.
