Purpose-built charging cable

This Fervit cable connects a rectangular jack input — used on ThinkPad X1 power supplies — to a USB-C device for power delivery up to 140 W. A woven braid jacket resists tangling and the 21 cm length keeps the link short and tidy. An integrated LED display shows voltage, current and power in real time so you can verify the charging rate at a glance.

Best for single-port charging, not data or video

It suits owners of compatible Lenovo ThinkPad X1 chargers who want to power USB-C laptops, tablets or phones that accept 5 V, 9 V or 20 V profiles. The cable carries only power; it does not transmit video or data, so users who need a full-featured USB-C link for displays or peripherals should choose a different cable.

Rectangular jack to USB-C with LED metering

The defining spec is the proprietary rectangular jack on the input side paired with a USB-C output that delivers up to 20 V at 7 A. That connector shape only fits the matching ThinkPad X1 power supply, so the cable works only when that specific charger is available.

Questions about this item

Does the LED display on this 140 W cable generate noticeable heat during all-day charging?

The LED display only shows voltage, current and power; it draws negligible power itself, so it adds no measurable heat during continuous use.

What power source must I already have to reach the 140 W rating on this 21 cm cable?

You need a USB-C charger or dock that can deliver 20 V at 7 A (140 W) and supports the PD profiles listed for this cable.

Will this Rectangle Jack cable charge my 2018 MacBook Pro at full speed alongside newer USB-C laptops?

Yes, it supports 5 V, 9 V and 20 V PD outputs up to 140 W, so a 2018 MacBook Pro and newer USB-C laptops both charge at their maximum negotiated rate.
