Portable DC-to-USB-C adapter

This cable converts a 7.4x5.0mm DC barrel input into a USB-C output for laptops, tablets and phones. It targets users who need to power USB-C devices from an existing barrel-style charger or power supply. The 21cm length keeps the connection tidy on a desk or in a bag.

LED metering and protocol support

An integrated LED display shows real-time voltage, current and power so you can verify the negotiated rate at a glance. The adapter handles PD alongside QC 2.0, QC 3.0, DCP, PE+ 1.1, PE 2.0, FCP, AFC, SFCP and SCP profiles. Output steps include 5V/1.5A, 9V/2A and 20V/7A up to 140W maximum.

Braided jacket and fixed connectors

A woven braid sleeve resists tangling and protects the conductors during frequent transport. Both ends are moulded directly onto the cable, so there are no detachable tips to lose. The short, fixed layout suits stationary charging but cannot reach distant wall outlets without an extension lead.

Questions about this item

How often will the woven braid sleeve on this 21cm cable need replacing under daily use?

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

What power limit appears first when running this cable at full 140W output continuously?

The cable’s maximum output is 140W at 20V/7A; sustained operation at that level is limited by the 20V/7A rating and the DC 15V‑20.5V input range.

How much heat does the LED display generate when the cable charges at 140W all day?

The LED display shows voltage, current and power in real time and adds negligible heat; the cable is rated for 140W continuous throughput without thermal throttling.
