What the cable does and who needs it

This Fervit cable connects a rectangular-jack power source to a USB-C device, delivering up to 100W at 20V 5A. It supports PD and multiple fast-charge protocols including QC 2.0, QC 3.0, PE 1.1 and PE 2.0. The 18 cm braided length suits travellers who carry a compact charger for laptops such as Mac Pro 2018, 2019, 2020 or XPS models. Buyers who need a longer reach or a straight USB-C-to-USB-C cable cannot use this product.

Thermals noise and power in normal use

The cable handles 100W maximum output with selectable 5V 1.5A, 9V 1.5A and 20V 5A steps, drawing from a 15V-20V DC input. No active cooling or fan is present, so operation is silent. The woven braid sleeve resists tangling and heat build-up during sustained high-current charging. Users must verify their device voltage and current rating before connecting to avoid damage.

What the bundled items change

No extra accessories or software are included in the package. The cable itself is plug-and-play, requiring no drivers or configuration utilities. Its only functional addition is the rectangular-jack connector that matches specific ThinkPad X1 power inputs, enabling those laptops to charge from a standard USB-C PD source. Without a compatible rectangular-jack power supply the cable cannot be used.

Questions about this item

How do I plug the rectangular jack into my ThinkPad X1 and which way round does it go?

Align the rectangular jack with the ThinkPad X1 power port and push straight in; the keyed shape only fits one way so it cannot be inserted backwards.

Will the woven braid sleeve wear out or need replacing after frequent bending?

The tangle-free woven braid sleeve is built for long-term rugged durability and requires no scheduled replacement under normal use.

At what point does the cable hit its thermal or current limit during continuous 100 W charging?

The cable is rated for a maximum of 100 W at 20 V / 5 A; sustained operation at that level is within its design limit.
