USB-C to DC 3.0×1.1mm adapter

This compact adapter converts a USB-C Power Delivery source into a DC 3.0×1.1mm barrel output for laptops that use that connector. It targets users who want to charge a compatible notebook from a high-wattage USB-C charger instead of the original brick.

100 W limit and charger requirement

The adapter delivers up to 100 W at 20 V and 5 A, but only when the connected USB-C charger and cable are also rated for 100 W or more. It also accepts 65 W sources and voltages between 18.5 V and 20.5 V, though maximum output drops accordingly.

Check DC jack size and charger rating

Verify that your laptop uses a 3.0 mm outer diameter and 1.1 mm inner diameter barrel jack before ordering. Ensure your USB-C charger and cable support at least 100 W if you need the full 20 V 5 A output. Not for devices with different barrel sizes or proprietary connectors.

Questions about this item

Should I choose the 3.0×1.1 mm jack or a different size for my laptop?

This adapter only provides a 3.0×1.1 mm DC male plug. Check your laptop's charging port dimensions before buying; if the jack size differs you will need a different adapter.

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

It can pass up to 100 W at 20 V / 5 A from a compatible USB-C charger to the DC jack. Your charger and cable must also be rated for 100 W or higher to reach that maximum.

Which USB-C charging standards does the adapter support and what do they limit?

It works with USB PD and QC 2.0 / 3.0 sources. The built-in trigger requests 20 V at 5 A, so output is capped at 100 W; lower-power chargers will deliver less, down to 65 W or the 18.5–20.5 V range.
