USB-C to DC 19V adapter for laptops

This adapter connects a USB-C power source to a laptop that uses a 4.0×1.7 mm DC barrel jack. It is intended for users who want to power or charge such a laptop from a compatible USB-C charger instead of the original brick.

Works with 65 W or 87 W chargers delivering 18–20 V

The adapter requests 18 V to 20 V from a 65 W or 87 W USB-C charger and passes that voltage to the DC plug. It does not support 5 V output, so it cannot run from standard phone chargers or low-power ports. The connected charger must be rated higher than the laptop's draw.

90° angled DC plug with 4.0×1.7 mm tip

The output connector is a right-angle barrel plug measuring 4.0 mm outer diameter by 1.7 mm inner diameter. Only laptops that accept this exact tip size and a 19 V input will work with the adapter.

Questions about this item

Will this adapter let me keep using my existing 65 W USB-C charger with a laptop that needs a 4.0×1.7 mm DC jack?

Yes, the adapter accepts a 65 W or 87 W USB-C charger at its Type-C female input and delivers 18 V–20 V through the 4.0×1.7 mm DC male plug, provided the charger’s rated power exceeds the laptop’s requirement.

How can I confirm the adapter is delivering the correct voltage after I plug it in?

The built-in PD emulator trigger negotiates a 18 V–20 V profile with the charger; you can verify output with a multimeter on the DC plug — it should read within that range and never drop to 5 V.

Does the package include a USB-C charger or only the 90° adapter cable?

Only the 90° angled USB-C female to DC male adapter is supplied; a 65 W or 87 W USB-C charger must be purchased separately.
