DC Jack 5.5x2.1mm to USB-C 140W cable

This 21 cm adapter converts a 5.5 mm by 2.1 mm DC barrel input into a USB-C output capable of delivering up to 140 W. An integrated LED display shows real-time voltage, current and power so you can monitor the charging status of a laptop, tablet or phone. The woven braid jacket resists tangling and adds durability for daily carry. It is built for users who need a compact bridge between a high-wattage DC source and modern USB-C devices.

Replaces bulky proprietary chargers

Instead of carrying a manufacturer-specific power brick, this cable lets you run a compatible USB-C laptop from a 15 V to 20.5 V DC supply rated for up to 140 W. The step up makes sense when you already own a suitable DC source and want a lighter, plug-and-play connection with on-screen power metering. It supports output profiles of 5 V 1.5 A, 9 V 2 A and 20 V 7 A across multiple fast-charge protocols. The short length keeps the setup tidy on a desk or in a bag.

Suits travelers with high-power USB-C laptops

Professionals using 140 W, 100 W or 65 W USB-C machines such as recent MacBook Pro or Dell XPS models gain a compact charging option with live power readout. Buyers whose devices require more than 20 V input or exceed 7 A current should look elsewhere. Anyone needing a longer reach than 21 cm or a different barrel size will need an alternative cable. The display adds value only if you actively monitor charge rates.

Questions about this item

What size DC barrel jack does the cable accept for power input?

The cable has a 5.5x2.1mm DC jack input that accepts a compatible barrel plug from your power supply.

How do I connect the cable so the LED display shows voltage and current?

Plug the DC barrel end into a 15V to 20.5V source, then insert the USB-C plug into the device; the display activates automatically when power flows.

When should I replace the cable if the braided sleeve shows wear?

Replace it if the woven jacket frays enough to expose inner conductors or if the USB-C or DC connectors become loose during use.
