Product identity

This Fervit cable converts a rectangular 11.0 by 4.5 millimetre DC jack into a USB-C Power Delivery output. It is built for owners of compatible laptops, tablets or phones who want to charge those devices from an existing 15 to 20 volt DC power source.

Critical specification

The cable accepts a DC input between 15 and 20 volts and delivers up to 65 watts through USB-C with selectable profiles of 5 volts at 2 amps, 9 volts at 3 amps or 20 volts at 3.25 amps. Matching the source voltage and current to the device requirements is mandatory to avoid damage.

Capacity and limits

The 65 watt ceiling comfortably powers ultraportable laptops, tablets and phones that negotiate supported PD or legacy quick-charge protocols. Devices demanding more than 65 watts or requiring an input voltage outside the 15 to 20 volt window cannot be used with this adapter.
