Single USB port outlet for use with puck mount?

I'm having a hard time finding a single USB port outlet like the one shown here: https://cdn.shopify.com/s/files/1/1116/7826/products/Puck_USB_Wallmount_Stud.png?v=1573846066

I can find outlets with multiple USB ports, but not single port ones. Anyone have a pointer to one like this? 

Thanks!
