Fervit USB 3.1 Type-C to Rectangle 11.0x4.5mm PD Trigger Charge Cable

SKU CH-06FV-EBZF7

Connects a 65W or 87W USB-C charger to a rectangular 11.0x4.5mm laptop port, triggering 18-20V DC output

  • Charge legacy laptops from modern USB-C chargers
  • Built-in PD trigger negotiates 18-20 V output
  • Rectangular 11.0×5.0 mm plug fits compatible ports
  • Works with 65 W or 87 W USB-C power sources
  • USB 3.1 Type-C female input for broad charger compatibility

Purpose and fit

This cable lets owners of Lenovo ThinkPad X1 Carbon models with an 11.0×4.5 mm DC barrel port use a 65 W or 87 W USB-C PD charger instead of the original brick. The integrated trigger negotiates 18 V or 20 V output, so the laptop receives the voltage it expects. It is not for devices that only accept 5 V over USB-C or that use a different barrel diameter.

Connector quality and daily use

The USB-C female end accepts any standard 65 W or 87 W PD charger, while the rectangular 11.0×5.0 mm male plug mates securely with the laptop socket. A moulded strain-relief protects the junction during frequent connect and disconnect cycles. The trigger circuit is embedded in the USB-C housing, keeping the cable profile slim for travel bags.

Power behaviour

The adapter requests 18 V or 20 V from the charger and passes that voltage directly to the laptop; 5 V is not supported. The charger must be rated at or above the laptop’s power draw, otherwise the trigger will not negotiate the required voltage. No active cooling is present, so the cable runs warm only under sustained high-load charging.

Questions about this item

Does the USB 3.1 Type-C input support 65 W and 87 W PD chargers?

The cable accepts a USB-C female input from a 65 W or 87 W Type-C PD charger and negotiates 18 V to 20 V output.

What is the exact size of the rectangular DC plug that fits the laptop?

The output plug measures 11.0 mm by 5.0 mm and is a male rectangle connector for compatible laptop ports.

How do I connect the cable so the PD trigger activates correctly?

Plug the USB-C charger into the cable's Type-C female end first, then insert the 11.0×5.0 mm rectangle into the laptop; the charger must exceed the laptop's power requirement.
