Anker powerbanks have several models with USB-C ports as output and also USB-A ports as output.
Firstly, you need to find the model of your powercore. If the Powercore comes with a USB-C port, then need to find either in the listing or in the instruction manual whether the USB-C port is only input or it does have output function too.
A few of the models we have are equipped with USB-C ports but with the input-only function, which means they cannot be used to charge other devices via USB-C ports such as Anker Powerbank 313 (A1229) and Anker Powerbank 325 (A1268). But these models have USB-A ports as output that still can be used to charge iPhones with. This USB-A port can be used to charge iPhones with USB A to lightning cable. Please find it here.

For example, Anker Powerbank 313 has two input ports (USB C+Micro USB) and only one output (USB-A port). So the recommended cable above (USB A to Lightning cable), you can use to charge your iPhones with this kind of Anker Powerbank model.
Most of the new models of Anker Powerbanks are equipped with USB-C ports as input/output both functions. Some of the Powerbanks have more than one USB-C port, so in these powerbanks, at least one USB-C port has a dual input/output function (which means it can also use to recharge itself and also use to charge other devices) such as in Anker Powercore Elite 26K has two USB-C ports both have dual
Input/output function in both of its USB-C ports. In this scenario, the recommended cable to charge your iPhones with is called “USB-C to Lightning cable”. Please find it here.

For example, Anker 737 Powercore 24K USB-C port information is in the diagram below:
If you see this Anker 737 Powerbank 24K (A1289). There are two USB-C ports, but only one USB-C which is “C1” has an nput and output port function, which means it can charge itself via the USB-C1 port and also it can be used to charge other devices via the USB-C1 port too, while the other USB-C2 port is only output port, it cannot be used to charge itself. It can only be used to charge other devices. So the recommended cable above (USB-C to Lightning cable), you can use to charge your iPhones with this kind of Anker Powerbank model.
