Power Adapter for USB-C Charging

This eForChina adapter converts a 4.0 x 1.7mm DC barrel input into a USB-C female output so you can power a USB-C device from a compatible barrel jack supply. It supports 65W maximum power delivery across the listed voltage steps up to 20V 2.25A. The cable measures about 15cm and the housing is 70x30x17mm ABS.

Travel-Friendly Connector for Compatible Barrel

The plug-and-play design suits users who want a compact bridge between an existing 4.0 x 1.7mm charger and a USB-C laptop or tablet that accepts 5V, 9V, 12V, 15V or 20V input. It will not work with barrel jacks of a different diameter or with devices that require more than 65W.

Simple Plug-In Installation

Connect the barrel plug to the power source and the USB-C device to the female port; no drivers or configuration are needed. The short cable limits placement flexibility and the 15cm length may not reach between distant ports. Ensure the source voltage and current match one of the supported profiles before use.

Questions about this item

Which power supplies with a 4.0 x 1.7mm tip can connect to this adapter?

Any supply delivering 5V/3A, 9V/3A, 12V/3A, 15V/3A or 20V/2.25A up to 65W fits the 4.0 x 1.7mm jack on the 15cm cable.

Will a legacy barrel-tip charger still deliver full power through this USB-C female port?

The adapter passes the input voltage profiles unchanged, so a matching 65W barrel charger provides the same 5V to 20V levels to the USB-C device.

How do I confirm the 65W link is active after plugging in?

The connected USB-C device should show a 20V/2.25A or 15V/3A charge rate, matching the adapter's rated 65W output.
