USB-C PD to 4.0×1.7mm DC adapter

This adapter converts a USB-C Power Delivery source into a 4.0×1.7mm barrel jack for laptops that require DC input. It is aimed at users who want to power or charge a compatible laptop from a high-wattage USB-C charger or power bank.

Replaces a proprietary laptop charger

The adapter lets you leave the original brick at home when you have a USB-C PD charger rated at 100W or higher. The jump is worth it if you travel light and already carry a multi-port USB-C charger that can deliver 20V at 5A.

Check your laptop and charger first

Confirm the laptop uses a 4.0×1.7mm DC jack and accepts 20V input within the 18.5V to 20.5V range. Verify the USB-C charger and cable both support 100W PD; otherwise the adapter will fall back to 65W or lower.

Questions about this item

What clearance does the 90-degree angled DC 4.0×1.7 mm plug need beside my laptop port?

The right-angle design lets the connector sit flush against the chassis, so only a few millimetres of side space are required for the 4.0×1.7 mm barrel to mate with the female jack.

Which charger and cable ratings are required to trigger the 100 W PD profile?

Both the USB-C charger and the cable must be rated for 100 W or higher; otherwise the adapter will fall back to 65 W or the 18.5 V–20.5 V range.

Does the built-in LED display itself draw power that could affect long-term reliability?

The display is powered from the PD negotiation circuit and consumes only a few milliwatts, so it adds no measurable load and requires no separate maintenance.
