There are proprietary issues related to charging methods. Consequently, it ensures charging method abides by the specified voltage of USB-C output (between 4.40V and 5.25V) and does not change over time. Additionally it is not in a manner defined by USB methods.
Quick Charge technology runs at above recommended voltage level which is default. Thus, goes against the specifications. On the other hand, USB Power Delivery is an open source charging method.
“Created alongside USB-C, it is with specs even though it also increases voltage. The big difference is USB PD uses communication lines to negotiate power transfer. While proprietary methods take over the data lines for their negotiation. They do so because legacy USB connections, such as USB-A, don’t have comm lines.
There is no known risk with running proprietary charging standards over USB-C. Manipulating the data lines does disrupt data transfers. But when plugging into a wall charger or power bank there is no data transfer anyway. A few USB-C engineers warn against using any USB-C chargers with third party standards. Their concern is unforeseen consequences. Future technology may prove to be incompatible with such configurations. And pulling out a charger several years from now with a new device could have a bad result.
I have not run into any issues with these fast charging standards on this or any other charger. But as it is a spec violation I want you to be informed. If you’re a stickler for meeting USB-C specifications this isn’t a good charger for you. If you’re more pragmatic it works fine and has no known issues.”
