Power bridge for USB-C laptops

This cable converts a 5.5×2.1 mm DC barrel jack into a USB-C power input, letting you run compatible laptops and tablets from an existing 100 W adapter. It targets users who want a single charger for barrel-jack and USB-C devices without carrying two bricks.

18 cm braided link with 100 W headroom

The 18 cm braided cable supports up to 20 V at 5 A when fed by a 15–20 V source capable of 100 W, and also passes 5 V at 1.5 A and 9 V at 1.5 A for smaller devices. Length and fixed voltage steps mean it cannot negotiate intermediate levels or exceed the 100 W ceiling.

Replaces a dedicated USB-C charger

It upgrades a barrel-jack power supply into a USB-C source for MacBook Pro 2018–2020, XPS, Chromebook and other 20 V/9 V/5 V PD devices. Buyers whose laptops need more than 100 W, or whose barrel adapter tops out below 15 V, will not gain usable power from this cable.

Questions about this item

Will the 5.5 mm by 2.1 mm DC jack on this 18 cm cable fit the barrel connector on my older 65 W laptop charger?

The cable accepts a DC input of 15 V to 20 V, so it will work with a 65 W charger that delivers 20 V within that range and uses a 5.5 mm by 2.1 mm plug.

How can I confirm the cable is delivering the negotiated 20 V 5 A profile after I plug it in?

Check the charging indicator on your USB-C device; it should show a 100 W or 20 V 5 A rate when the source and device both support that PD profile.

Does the package include a DC power adapter or only the braided USB-C to DC jack cable?

Only the 18 cm braided cable with a 5.5 mm by 2.1 mm DC jack on one end and a USB-C plug on the other is supplied; a compatible DC power source must be provided separately.
