Purpose and audience

This 18 cm cable converts a DC 7.4x5.0 mm barrel jack into a USB-C power input, delivering up to 140 W at 20 V/7 A. It targets laptop owners who need to power or charge USB-C devices from a compatible DC source.

Build integration

The woven braid jacket resists tangling and adds durability for portable use. It requires a DC supply rated 15 V to 20.5 V and a USB-C device that accepts 5 V/1.5 A, 9 V/2 A or 20 V/7 A profiles. No software or drivers are involved.

Who it suits and who it does not

Suits users with a matching barrel-output adapter and a USB-C laptop, tablet or phone that operates within the listed voltage and current limits. Not for buyers whose DC source falls outside 15 V to 20.5 V, whose device needs a different charge profile, or who need a longer cable for desk routing.

Questions about this item

Will the 18 cm length reach my laptop without strain?

The cable measures 18 cm including both connectors, so it only spans a short gap between the DC jack and the USB‑C port.

Does the cable get hot when delivering 140 W continuously?

The braided jacket is designed for rugged durability and heat dissipation during sustained 140 W charging sessions.

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

You need a DC supply with a 7.4 × 5.0 mm plug that can output 15‑20.5 V and at least 7 A to reach the 140 W rating.
