QC3+ is compatible with USB-PD I believe. This means they are compatible with both QC and USB-PD.Aren’t android phones compatible with quick charge from Qualcomm? Doesn’t that make a lot of them incompatible with PD?
Also this EU rule is not yet in charge. The deadline is December 28th, 2024 after that even Android phones will have to comply, yes. So up to 100W USB-PD is mandatory. Above 100W custom protocol is allowed. I.e. if your device handles 120W, you have to allow 100W USB-PD, but you can have also 120W QC. That's how I understand the EU's 'Common Charger' directive.
