One other thing that is pretty cool with the mini - I power it over USB C via a cable that starlink sells.My starlink mini pulls around 20-25 watts once running. Maybe double that for the first 10-15 minutes. So, you can just do some math to get an idea of how long any give battery pack will run it.
And the $50.00 for 50gb roam plan is pretty nice if you are not using it a ton. A single teams video call used like 8gb an hour, but I barely used any data for most of the time. Even teams voice calls were not too bad.
