Compatibility between Quick Charge (QC) and Power Delivery (PD)

[kiranmk2]

I'm looking to get a new charger for my UGreen qi wireless pad. Like most of the qi pads out there it has a microUSB socket on it and says that it requires a QC3.0 charger to charge at 7.5 W. However, the QC standard seems to be on the way out as USB-PD chargers come in. My question is - can I use a USB-PD charger plug with a qi charging pad (with a USB-C to microUSB cable) to get fast charging or am I limited to using a QC charger (with USB-A sockets)?

QC3 (and below) and PD still speak different languages and are not compatible.

QC4 is based on PD, and adds a superset of enhancements, so the two are compatible, but if the charger is designed to connect to a QC adapter, in all likelihood a QC3 adapter, it won't work with a PD adapter.

QC4 also requires a USB-C connector, so if your charger doesn't have one, it most assuredly is not QC4 compatible, and again, will not work with a PD adapter.

QC is cheap, has good market penetration, and as long as Qualcomm plays a role in mobile devices, isn't going anywhere.

Not sure QC will be around that much longer as Google has mandated that future Android phones must support PD so not sure the incentive for manufacturers to add QC will remain. https://www.theverge.com/2019/10/7/...ental-controls-usb-c-pd-charging-requirements

Think I will hold off any further qi pads until there are more supporting PD/USB-C
