140W Power Delivery Cable

This Fervit cable delivers up to 140W through a USB-C output using a rectangular jack input. It supports Power Delivery at 20V and 7A while automatically adapting to 100W and 65W devices. The 21cm braided design resists tangling and suits portable use with compatible laptops, tablets and phones.

Upgrade from Basic Charging Leads

The built-in LED display shows real-time voltage, current and power so you can confirm the negotiated rate at a glance. Multi-protocol support covers PD, QC 2.0, QC 3.0, DCP, PE+, PE 2.0, FCP, AFC, SFCP and SCP. The jump is worth it when you need visibility into the actual power flow and broad protocol coverage.

Build Integration Requirements

The cable accepts a DC input between 15V and 20.5V and negotiates output steps of 5V at 1.5A, 9V at 2A and 20V at 7A. You must verify that your source and device match these ranges to avoid damage. The short length keeps desk clutter low but requires the power brick to sit close to the device.

Questions about this item

What size is the rectangular input jack so I know if it fits my power adapter?

The cable has a rectangular jack input that plugs into a matching DC port on your power adapter; the compact 21 cm length keeps the connection tidy.

How do I connect this cable and what is the common mistake to avoid?

Plug the rectangular jack into a DC source supplying 15 V to 20.5 V, then connect the USB-C end to your device; the mistake is skipping the voltage check and using an incompatible adapter.

Will the braided jacket or LED display need replacement over time?

The woven braided jacket is built for durability and tangle-free use, and the integrated LED display is sealed into the cable, so neither component is designed to be replaced separately.
