USB-C to DC 7.9 by 5.4 mm cable 1.8 m

Fervit

Fervit USB-C 100W 20V to DC 7.9*5.4mm PD 65W Cable 1.8m

SKU CH-0W36-6JQVA

Converts a USB-C PD charger into a 20 V DC supply for laptops with a 7.9 × 5.4 mm barrel jack, delivering up to 100 W over 1.8 m

  • Charges laptops via USB-C using 100W PD trigger
  • Delivers up to 65W through 7.9×5.4mm DC barrel connector
  • Works with QC 2.0 and 3.0 chargers for broad compatibility
  • 8m cable length gives flexible desk placement
  • Requires charger rated above laptop draw for safe operation

Cable purpose and target user

This USB-C to DC cable connects a 100W or 65W Type-C charger to laptops fitted with a 7.9 by 5.4 mm barrel jack. It suits owners of compatible notebooks who want to use a single high-power USB-C supply instead of the original brick.

Sustained-load behaviour

The built-in PD emulator requests a 20V 5A contract from the charger, allowing continuous delivery of up to 100W through the 1.8 m cable. Output falls back to 65W when the source adapter is limited to that level, so the cable runs within its rated capability without throttling.

Deciding specification

The 7.9 mm outer and 5.4 mm inner diameter of the DC plug must match the laptop jack exactly; an incorrect barrel size will prevent connection regardless of charger wattage.

Questions about this item

Does the 100 W PD trigger generate noticeable heat during all-day charging?

The cable embeds a 100 W DC 20 V 5 A PD emulator trigger; heat depends on the charger and laptop load, not on the cable itself.

What charger must I already own for this cable to deliver 65 W to my laptop?

You need a USB-C charger that supports 100 W or 65 W PD output at 20 V; the charger power must exceed the DC output.

Will this 7.9 × 5.4 mm tip fit the 5.5 mm barrel port on my older laptop?

The tip is 7.9 × 5.4 mm, which differs from a standard 5.5 mm barrel; verify the laptop jack size before use.
