They did. It’s in the manual. You posted it above. That’s all you need in terms of specs.
I use a charging cable for a Minirig speaker:

The second one down on that page can be daisychained so you can power multiple devices from one port.
So are you saying all power banks 5V or 12V or whatever will work to power MC, I just don’t want to fry the MC, I want to power MC and a pair of monitors. I don’t understand how the 2nd one down powers multiple devices daisychained. I see a double headed USB plug on one end … thanks for your help.
The side input can accept 4–10V. I wouldn’t plug a 12V source in.
The Minirig cable has a USB plug that has a socket on the other end, so you can plug another USB cable in to power something else. I haven’t tried plugging multiple devices in yet though.
Pretty much all USB powerbanks (ie. the ones that are designed to charge a phone) put out 5V. Get one of those and the cable I mentioned and you’re good to go. I don’t know if you’d be able to power monitors from a USB powerbank, unless you don’t mean monitors and instead mean some portable speakers.
