The bike dynamo with its Intelligent Power Management System (IPMS) can pump out a stable 1A current from its 5V USB port when the speed of the bike reaches 15-17km/hour. I have done some field tests to find out its charging performance with an iPhone 11 Pro in different scenarios, including when the phone is in Airplane mode with no Apps running, when the phone is in Non-Airplane mode with no Apps running, when the phone is in Non-Airplane mode and used for navigation and tracking, and when the route involves some climbing.
