DC 4.5x3.0mm to USB-C 140W Cable

This new cable converts a DC 4.5x3.0mm input into a USB-C output with Power Delivery up to 140W at 20V/7A. A built-in LED display shows real-time voltage, current and power so you can see the charging rate at a glance. The 21cm braided jacket resists tangles and suits portable use. It is intended for users who need to power USB-C laptops, tablets or phones from a compatible DC source.

Suits owners of compatible DC power adapters

Buyers with a 15V to 20.5V DC supply that fits the 4.5x3.0mm barrel can use this cable to charge USB-C devices supporting PD, QC 2.0, QC 3.0, DCP, PE+, PE 2.0, FCP, AFC, SFCP or SCP. It automatically negotiates 5V/1.5A, 9V/2A or 20V/7A output. Users without a matching DC source, or whose devices lack USB-C charging, should look at other solutions.

15V to 20.5V DC input range

The cable only accepts an input voltage between 15V and 20.5V on the 4.5x3.0mm barrel connector. Supplying a voltage outside this range will prevent operation or risk damage. Verify that your power adapter delivers within this window before purchasing.

Questions about this item

What size DC barrel jack does the input connector need to fit?

The input uses a 4.5x3.0mm barrel connector that must match the laptop charger tip exactly.

How is the cable connected, and what voltage range must the source provide?

Plug the DC barrel end into a 15V to 20.5V power source, then connect the USB-C end to the device; the cable negotiates 5V/1.5A, 9V/2A or 20V/7A automatically.

When should the braided cable or LED display be checked for wear?

Inspect the 21cm braided jacket and LED screen if the display flickers or charging drops below the negotiated 140W, 100W or 65W levels.
