USB-C 100W to DC 4.5mm cable

This cable converts a USB-C Power Delivery source into a 4.5 by 3.0 mm barrel connector for laptops that still use a round DC jack. It targets owners of compatible notebooks who want to charge from a single USB-C brick instead of carrying the original adapter. The integrated trigger chip negotiates 20 V at up to 5 A with the charger.

Practical limits of USB-C PD and QC

The cable only delivers power when the connected USB-C charger can supply 20 V at 5 A, so a 65 W or 100 W PD or QC 2.0 and 3.0 source is required. If the charger cannot negotiate that voltage the laptop will not charge. The output is capped at the charger's capability, so a 65 W brick limits the cable to 65 W even though the cable itself handles 100 W.

Build quality and daily use

A moulded strain relief protects the USB-C plug and the barrel tip from bending stress during repeated insertion. The fixed 4.5 by 3.0 mm tip means the cable works only with laptops that accept that exact jack size, so buyers must verify the port before purchasing. No additional adapters or detachable tips are included in the package.

Questions about this item

Should I use the 65W or 100W USB-C charger with this cable?

Use a USB-C charger rated at 100W or 65W. The cable's built-in trigger requests 20V at up to 5A from the charger, so the charger must be able to supply at least the power your laptop needs.

What does the 100W rating mean when I plug this into my laptop?

The cable can pass up to 100W (20V at 5A) from a compatible USB-C charger to the DC jack. Actual power delivered depends on the charger's capability and the laptop's charging circuit.

Does the DC plug fit the 4.5mm or 5.5mm barrel jack on my HP laptop?

The cable terminates in a DC 4.5 * 3.0mm male plug. Verify your laptop's jack dimensions match this size before purchasing.
