This question is regarding about the USB 3 port and Thunderbolt 3 port on the back of the iMac Pro. was wondering can these ports be used to power and charge up other devices? like say iPad Pro, iPhone 11 Pro, and Apple Watch? and if so what is the amount of watts can these ports put out. 12 watts? 18 watts? etc...
iMac Pro
Yes you can, but some larger iOS devices like your iPad and even iPhone may take longer or even refuse to charge.
see > If your iPhone, iPad, or iPod touch won't charge - Apple Support
Personally I prefer to use the supplied cord and power adapter (wall charger) for each of my iOS devices.
yea that’s my back up plan if it doesn’t provide enough wattage for powering them up. I just want to have the cables to plug into one power source instead of having wires go down the back of my work desk my little OCD
Also, the ports probably don't provide power when the computer is off. Sleep should be OK.
