In May 2021, the USB-IF promulgated V2.1 of the USB-C cable charging standard. The most important update is to greatly increase the supported maximum voltage from 20V to 48V, while the current maintains 5A, so the maximum power reaches 240W, double from 100 watts to 240 watts, which will let you plug into more productive laptop and gaming computers, hopefully, you can throw your proprietary power chargers to the trash can.
What is USB-C 240W EPR?
USB-C 240W refers to a USB-C cable that can carry max 240 watts (double of max 100 watts previously) and with EPR (extended power range).
There is still a long way to go for USB-C 240W EPR
From the manufacturer’s point of view, the power supply capacity of USB-C 240 Watts is estimated to take some time to be practical, because the 48V voltage has exceeded the range of weak current and safe power consumption, the extreme working voltage may even be as high as 50.9V, which exceeds the safety voltage requirements of the human body, the withstand voltage value of the VBUS capacitor built in the data line needs to be higher than 50.9V, which is different from the previous 100W standard.
End-users can easily clarify USB-C cable by the certified logo
In addition to double charging from 100W to 240W, the USB-C V2.1 specification has also added more standardized certification information this time. Both data and power supply capabilities are clearly marked. There are complete logos for different speeds and power supply capabilities. In the future, you will be able to distinguish between the interface and the cable logo, and it will not feel as messy as now.
USB-IF stop USB-C 100W certification
In addition, the USB-IF has opened the 240W EPR Type-C data cable certification, in which EPR stands for “Extended Power Range” , the original 20V/5A 100W USB- C data cable has stopped certification. At present, some cable manufacturers have reported that the USB-C has not accepted the new 100W certification.
What to expect
With 240W charging, you can expect a USB-C cable can charge not only your laptop, phone but also the gaming laptop or more productive computer, or 4K TV, speakers, or any other smart displays, which will be more convenient and environmentally friendly, a 240W USB-C cable for all.
