What is the wattage output fr iMac 2015 model if I used the desktop to charge my phone?

Check System Information > USB.

The 2015 only has USB-A which will charge a modern phone but very slowly, it’s about equivalent to those small charging cubes Apple used to provide with the iPhone 5s/5/4s/4 etc. but charging an iPhone Pro Max on that connection will take a long time.

I can verify my iMac is USB 3.0. Anyway my question is not what version type of USB port but what is the wattage output
