Connector match

This cable bridges a USB-C power source to a laptop with a 7.9 by 5.4 mm DC jack. The built-in trigger negotiates 20 V at up to 5 A from a compatible charger. It is intended for users who want to power a barrel-port laptop from a modern USB-C supply.

Power negotiation limits

The cable only delivers 20 V output and requires a charger that can provide at least the wattage the laptop draws. It supports QC 2.0, QC 3.0 and USB PD protocols, but will not step voltage up or down. If the source cannot negotiate 20 V the laptop will not charge.

Output headroom

Maximum throughput is 100 W at 20 V 5 A, while 65 W operation is also supported. The cable handles laptops that draw up to its rated current, but cannot supply more than the negotiated 5 A. Buyers needing higher current or a different voltage must choose another solution.

Questions about this item

Which DC connector size matches my laptop — 7.9 × 5.4 mm or the 5.5 mm mentioned?

The cable ends in a 7.9 × 5.4 mm barrel; the 5.5 mm figure in the notes is a generic reference, so verify your laptop's jack measures 7.9 mm outer and 5.4 mm inner before buying.

What does the 100 W rating mean when I plug this into a 65 W charger?

The 100 W figure is the cable's maximum capability with a 20 V 5 A source; using a 65 W charger limits output to that charger's 65 W ceiling.

Will the USB-C PD trigger negotiate 20 V with any charger?

The built-in emulator requests 20 V 5 A via PD or QC 2.0/3.0, but the charger must explicitly support that voltage and current profile.
