Agreed. Huawei's 66 watt fast charger can charge an Apple phone, mainly because their charging protocols are compatible with each other. However, because the Apple phone's own charging power does not support 66 watts, with Huawei's 66 watt charger, it can still reach a maximum of 20 watts of charging power. Unable to reach higher charging power.
Huawei's 66 watt fast charge can charge Apple, but Huawei's 66 Watt fast charge does not support Apple's charging protocol, so the power cannot reach 66 watts, and can only maintain 5v 2a ten watts of charging power.
