I feel his pain!
It has taken way too long to add USB-C to my chargers, a combination of Covid and parts. A 4-port version with 2 x Type A and 2 x Type C will be available shortly. Literally just waiting for the assembled PCB panels to arrive. The website will be updated in a couple of weeks, including options to upgrade a current v2 charger to USB-C.
Trying to get parts is still a huge problem, even for contract custom electronics projects. There can be 5000 processors on a Monday, go to order on Wednesday, and they've gone. Just left with the option to back order for delivery in 2024. Crazy.
