2020 Mac Mini - 3.5 MM audio jack power output?
Did anyone know the power output on the 3.5mm jack on 2020 and later Mac Mini's?

It's a standard 3.5-mm headphone jack. The new Mac Studio offers 3.5 mm headphone jack with advanced support for high-impedance headphones! If that is what you want to know.
Headphones are measured by their Impedance not Voltage, here's a bit more: Headphone Buying Guide: What Is Headphone Impedance?

There still is a level of power output that's dependent on resistance levels. There is a range of voltage in relation to resistance and that's the range I wanted to know. Apple has posted it for studio, macbook 14 & 16" (2021) and I needed this info for the mini as well
@Steve Madden - The voltage is proportional to the impedance of the load.
Standard headphone jack:
Maximum output voltage drive: 150mV
Microphone bias voltage: 1.8V - 2.9V
What are you trying to do? Maybe it would be better to understand the concern.
As I tried to explain the newer Mac systems now offer advance support of high-impedance headphones: Use high-impedance headphones with MacBook Pro (2021) and Mac Studio
The first Gen of the M1 systems only offered the older design.
So I just measured the voltage of the jack when split to two RCA plugs. I get 1 volt RMS at 1000 hZ on the meter.
