Type C to lighting cable is original?
Can the power bank charge other phone?
Test the type with other devices that is type c too. Possible your type c port may be broken
I read on HWZ the xiaomi pro power bank 10000 mah type c port cannot be use to charge your devices. It’s only used for charging the Pb itself.
Your usb c to lightning must be mfi certified i think only anker and the original apple cables are certified for now.
there are a lot of mfi usb c to lightning cable now, anker is not the only that has it. in fact the first one I have seen is from xiaomi, I am not sure if it is sub branded under zmi.
Any good recommended power bank with power delivery that I can buy locally?
