Thank you. This solution works!
I was led to believe that my existing cable and brick would not work, since Apple provided a new cable with the iPhone 13 that has a different connector. This new cable is of no use to me, since I have no charging devices with this new connector style.
Why would Apple provide half of a charging solution? Why not include something in setup or in the box to let users know that lightning cables and bricks from older iPhones will work with the iPhone 13? Apple knew I had an iPhone 8, as I am trading it in with the purchase of this new iPhone.
Apple could have saved even more money and e-clutter by providing neither the cable or the brick.
User experience needs improvement here.
