Short black cable with USB-C female socket and 5.5×2.1 mm DC barrel plug

Fervit

Fervit USB-C Female to DC 5.5×2.1mm PD Cable 65W 18-20V 0.2m

SKU CH-TP83-909ND

Connects a 65 W USB-C PD charger to a 5.5×2.1 mm DC laptop port delivering 18–20 V in a 0.2 m cable

  • Converts USB-C PD power to 5.5 × 2.1 mm DC output
  • Built-in PD trigger negotiates 18-20 V from a 65 W charger
  • 2 m cable keeps desk clutter minimal
  • Designed for HP laptops requiring 18-20 V DC input
  • Does not support 5 V output, ensuring correct voltage delivery

Purpose & Audience

This short adapter cable lets you power a laptop that uses a 5.5 mm × 2.1 mm barrel jack from any USB-C charger capable of 65 W Power Delivery. It is built for owners of compatible HP notebooks who want to travel with a single compact charger instead of the original brick.

Voltage Negotiation

The cable contains a built-in PD trigger that requests 18 V to 20 V from the source; it does not negotiate 5 V, so the connected charger must support the higher PD voltage profile. A USB-C charger rated below 65 W or limited to 5 V will not activate the output.

Capacity Limits

At 65 W the cable comfortably runs most ultraportables and charges their batteries under normal workloads. It reaches its limit with larger laptops that draw more than 65 W or require a voltage outside the 18 V to 20 V window, and the fixed 0.2 m length restricts placement to very close proximity between charger and device.

Questions about this item

What does the 65 W rating mean when I plug this into my laptop?

The cable can pass up to 65 W from a compatible USB-C charger to a laptop that accepts 18-20 V through the 5.5×2.1 mm barrel connector.

Which USB-C power standard does the built-in trigger use and what voltage does it request?

The integrated PD emulator trigger negotiates 18-20 V from a 65 W USB-C charger; 5 V is not supported.

What clearance does the 0.2 m cable and 5.5×2.1 mm plug need at the laptop port?

The 0.2 m length leaves only a short tail, so the barrel plug must sit directly at the laptop's DC jack without strain.
