BUCIER 100W PD DC 6.3 x 3.0mm Adapter

This adapter converts a DC 6.3mm x 3.0mm female input into a USB Type-C male output, delivering up to 100W of Power Delivery. It contains a built-in PD automatic identification chip that negotiates 5V, 9V or 20V output profiles for connected devices.

Suits users with barrel-tip chargers and USB-C

It works when the original DC charger supplies more power than the laptop requires; for example a 90W source can run a 65W or 86W notebook. Buyers whose charger power equals or falls below the laptop demand should look elsewhere, as the adapter will not function in that scenario.

Input must exceed laptop power draw

The critical rule is that the DC source must be rated higher than the laptop's maximum consumption; equal ratings such as 90W-to-90W will not operate. Verify your charger's wattage against the laptop specification before purchasing.

Questions about this item

Does the package include a DC 6.3 x 3.0 mm power supply or only the adapter?

The box contains one DC 6.3 x 3.0 mm female-to-USB-C male adapter. The DC power supply itself is not included and must be purchased separately.

My laptop needs 90 W — can I use this 100 W adapter with a 90 W DC charger?

No. The input power must exceed the laptop power. A 90 W DC charger cannot drive a 90 W laptop through this adapter; you need a DC charger rated above 90 W.

The adapter is rated 100 W at 20 V — what current does that deliver to my laptop?

At the 20 V PD profile the adapter supplies 5 A, giving the full 100 W to a compatible USB-C laptop.
