Teardown of Baseus 240W USB-C Cable
Introduction
Following the Power Delivery 3.0 standard, the USB-IF introduced its latest PD 3.1 specification in May 2021. New features include EPR, which was added to expand the maximum power of the PD 3.0 power supply from 100W all the way to 240W (48V 5A). And today, we got our hands on a 240W USB-C cable from Baseus, which supports the latest PD 3.1 specification.
