Anker 523 Power Bank (PowerCore 10K) comes with 3 accessories:

1. 2ft / 0.6m USB-A to USB-C cable
2. 2ft / 0.6m USB-C to USB-C cable

We recommend using the included USB-C to USB-C cable with this power bank. Using a  USB-C cable and Power Delivery wall charger will enable the fastest recharging speed. If you use a USB-A to USB-C cable with a 5V/2A wall charger, the recharging time is 10.5 hours. Any random USB-C to USB-C/ USB-A to USB-C cable can be used.
