    Charging iPhone using USB-C connection
    Is it possible to charge my iPhone7, without causing damage to it, using an Apple cable with a lightening connector on one end, for the iPhone, and a USB-C (thunderbolt) connector on the other end, to plug into my iMac, for charging?

    Which model/year iMac? I don't think it should matter, because both the iMac and the iPhone should have smart power/charge capabilities.

    Please backup. Everything has a life cycle, unexpected and warning free. Nothing will last as long as you want it to.

    A warm welcome to Mac-Forums, Louiss97 and thank you for your post.

    The answer is yes, probably.

    Have a read at these Apple & other articles on this:

    About the Apple USB-C to Lightning Cable – Apple Support
    What's the difference between USB-C and Thunderbolt? | iMore (do read this)
    About the Apple Thunderbolt 3 (USB-C) Cable – Apple Support

    A quote from the second reference may help: "You can plug a USB-C device and cable into a Thunderbolt 3 port whenever you want because Thunderbolt 3 fully supports USB-C."

    So I think it should be okay.

    Of course, that should be completely fine. Thunderbolt is capable of providing significantly more power than what USB can provide, but that doesn't mean it can't throttle back down what the end device needs.
