USB-C to DC 4.5mm coiled charge cable with inline trigger module

Fervit

Fervit USB-C 100W 20V to DC 4.5mm 65W Charge Cable

SKU CH-09RG-TA75V

Converts a USB-C 100W or 65W charger into a DC 4.5mm 20V 5A power source for compatible laptops

  • Charges laptops via USB-C using 100 W PD trigger
  • Delivers 65 W at 20 V through 4.5 mm DC jack
  • Works with QC 2.0 and QC 3.0 chargers
  • Requires charger rated above 65 W for full output
  • Compatible with 5.5 mm barrel-port laptops

Purpose and compatibility

This Fervit cable converts a USB-C Power Delivery input into a DC 4.5 mm barrel output for laptop charging. It accepts a 100 W or 65 W Type-C charger and delivers up to 20 V at 5 A, with a maximum output of 100 W and a 65 W mode also supported. The built-in PD trigger negotiates the required voltage automatically.

Who this suits and who it does not

It suits owners of laptops that charge through a 4.5 mm DC jack and who already carry a compatible USB-C PD charger. It will not work for devices that require a different barrel size such as 5.5 mm, nor for laptops that draw more power than the connected USB-C charger can supply. Buyers needing a straight USB-C to USB-C cable should look elsewhere.

Sustained-load behaviour

The cable passes the negotiated 20 V 5 A continuously as long as the source charger maintains its rated output. Because the conductor cross-section is fixed, extended operation at the 100 W limit will warm the cable more than brief bursts, but the PD handshake prevents over-voltage. Ensure the charger’s continuous rating meets or exceeds the laptop’s demand to avoid throttling.

Questions about this item

Which USB-C charger do I need to power this cable?

You need a USB-C charger that delivers 100W or 65W and supports PD or QC 2.0 / 3.0 so the built-in 20V 5A trigger can negotiate the correct voltage.

Will this cable charge a laptop that uses a 5.5 mm barrel jack?

No — the output plug is 4.5 × 3.0 mm, so it only fits laptops with that exact DC jack size.

How can I confirm the cable is delivering 65 W to my laptop?

Check the laptop's battery indicator while charging; it should show a 20 V input and the charge rate matching the 65 W output the cable is rated for.
