There is more to USB than just wire and connectors these days. Have a look at this site: What is PPS Fast Charging, and What’s the Difference Between PD, QC, and PPS? https://blog.ravpower.com/2021/02/pps-fast-charging/ Mobile devices are becoming more powerful by the day and their power consumption has increased drastically, making fast charging indispensable. In 2017, the USB Implementers Forum (USB-IF), the organization that supports the advancement of USB technology, added PPS fast charging to the USB PD 3.0 standard, creating a unified solution for today’s fast charging devices. That same year, Qualcomm’s QC 4.0 met the PPS standards, attaining a unified charging scheme. So, what is Programmable Power Supply (PPS)? PPS fast charging is the most advanced charging technology for USB-C devices. The technology adjusts the voltage and current in real-time, depending on a device’s charging status, feeding it with maximum power ... etc If you want to get down and dirty, this is a pdf on the design of USB Power Delivery: https://usb.org/sites/default/files/D2T2-1%20-%20USB%20Power%20Delivery.pdf -- Regards brd Bernard Robertson-Dunn Canberra Australia email: [email protected] _______________________________________________ Link mailing list [email protected] https://mailman.anu.edu.au/mailman/listinfo/link
