DC 5.5x2.5mm to USB-C adapter cable

This 21cm cable converts a DC 5.5x2.5mm barrel input into a USB-C output rated for up to 140W. It targets users who want to power USB-C laptops, tablets or phones from an existing DC power source without carrying a bulky brick.

Woven braid sleeve and plug-and-play design

The tangle-free braided jacket protects the conductors during frequent transport and the short length keeps cable clutter to a minimum. An integrated LED display shows real-time voltage, current and power so you can verify the negotiated profile at a glance. It requires a DC source capable of 15V to 20.5V input and a USB-C device that accepts 5V, 9V or 20V PD profiles.

Sustained 140W delivery

When paired with a 140W-capable DC supply and a compatible device, the cable maintains a continuous 20V 7A output rather than throttling after a short burst. Supported protocols include PD, QC 2.0, QC 3.0, DCP, PE+1.1, PE 2.0, FCP, AFC, SFCP and SCP, allowing the adapter to settle on the highest stable voltage the load requests. Buyers whose DC source cannot reach 20V or whose device lacks 20V PD support will not achieve the maximum rating.

Questions about this item

Will the 140 W output hold steady during long charging sessions?

The cable delivers up to 140 W at 20 V / 7 A when paired with a 140 W source and a compatible device; sustained output depends on the power supply and the device's own power management.

Does the LED display or the braided jacket add noticeable heat or noise?

The cable is passive with a woven braid sleeve and an LED digital display that shows voltage, current and power; it has no fan or active components, so it adds no audible noise and minimal heat.

What power source must I already have to use this cable?

You need a DC 5.5 × 2.5 mm power supply that provides 15 V to 20.5 V input and can deliver up to 140 W for the cable to reach its maximum 20 V / 7 A output.
