charger for iPhone 13 Pro Max

iPhones no longer ship with a power adapter. They ship with a Lightning to USB-C cable.

Options include:

If you have both the Lightning to USB cable and the USB power adapter from a previous iPhone, you can use those.

If you want to buy a power adapter that fits the cable that came with the new iPhone, one option is Buy 20W USB-C Power Adapter - Apple

If you want to buy a Lightning to USB cable that fit an older power adapter, one option is: Lightning to USB Cable (2 m) - Apple

No iPhone has a USB-C -- they all have a Lightning connector. The iPhone 13 comes with a Lightning to USB-C cable but you can use a Lightning to USB cable with it as well and if you have that cable you can connect it to USB power adapters, including a 10W.

Can I use a 10W power adapter to charge a iphone 13 that has a usb-c

Thank foxfifth for you answer. It great to know I can use any of my adapters on the iphone 13, Leo
