What is EPR? The simple version is Extended Power Range, a higher rate of power delivery (240w).

Our new range of USB 4 cables support EPR and are available with 20Gbps or 40Gbps transfer speed.

All these cables also use e-marker chips. Why do USB C cables need an E Marker chip?

With the rapid popularity of USB PD fast charging in mobile devices such as notebooks and mobile phones, many USB PD cables that support high current output are equipped with E-Marker chips. This tiny chip plays a vital role in modern mobile devices and chargers, but why is it so important?

Many USB PD chargers that support high power output are equipped with E-Marker chip USB-C cables. But the problem is, there are differences between different E-Marker cable types. Some can deliver up to 240W of power, while others can only deliver 100W and below. Some cables can achieve transfer speeds of up to 40Gbps, while others only support USB 2.0, with a maximum data transfer speed of only 480Mbps. Embed E-Marker in the USB-C cable to ensure that charging is under a safety protection mechanism when the power adapter output current is greater than 3A.
