Black cable with USB-C plug on one end and rectangular 11.0 by 4.5 mm DC connector on the other

Fervit

Fervit USB-C to DC 11.0×4.5 mm 135W PD Charge Cable

SKU CH-GPTG-ABZ0E

Charges compatible laptops through a rectangular 11.0×4.5 mm DC port using a 135 W or 140 W USB-C charger

  • Delivers up to 135 W charging via integrated PD trigger
  • Works with 135 W or 140 W USB-C power adapters
  • Fits laptops using an 11.0 × 4.5 mm DC rectangle port
  • Compatible with ThinkPad X1 and Legion Y7000 series
  • Supplies 20 V at 6.25 A for full-speed laptop power

Purpose and compatibility

This cable converts a USB-C power-delivery source into a DC rectangle connector measuring 11.0 by 4.5 mm. It is intended for users who want to charge compatible laptops such as the ThinkPad X1 or Legion Y7000 series from a high-wattage USB-C charger.

Power delivery and thermal behaviour

The integrated PD trigger requests 20 V at 6.25 A for a maximum of 135 W from a 135 W or 140 W USB-C charger. Because the adapter is passive aside from the trigger chip, it adds negligible heat and no audible noise during normal charging.

Build integration and constraints

The cable requires a USB-C charger rated at 135 W or higher; lower-wattage sources will not provide the negotiated voltage. It frees the user from carrying the original proprietary brick but cannot charge devices that need a different DC barrel size or a lower fixed voltage.

Questions about this item

How do I connect the 11.0×4.5 mm rectangle plug and what step do people miss?

Plug the USB-C male end into a 135 W or 140 W PD charger first, then insert the rectangle male into the laptop DC jack; the built-in trigger only negotiates 20 V 6.25 A when the charger advertises 135 W or higher.

What part of this cable wears out first and needs replacement?

The USB-C male connector and the rectangle male tip endure repeated insertion cycles; the internal PD emulator trigger is solid-state, so mechanical wear on the two plugs is the typical failure point.

At what power level does the cable hit its limit during a long charge session?

The cable is rated for 135 W maximum output at 20 V 6.25 A; sustained loads above that will exceed the built-in trigger’s negotiated profile and the cable will not pass more power.
