Wired: iPhone (or iPad ) with Lightning connector
This should be straight forward if you have the correct cables and charger.
Connect the FLX4 to a fast, high power charger (I have tested several and the minimum is a 20w, 9v 3A USB-C charger), using the included USB-C-C cable to the power socket on the controller.
Connect the FLX4 from the “device” socket to your iPhone / iPad with a USB-C to Lightning cable (provided with iPhones in the last few years). This should connect and also charge your phone.
