I had my Mini set up outside and extended the power line as far as it would go, but then once inside, the Wifi signal was very weak, even just 30' away.
So I've ordered the Ethernet cable, and will attach it to a simple Wifi extender that's also at the point of power, so the inside signal is strong.
They really should have thought of this in the design -- going through walls is always a challenge.
The idea design would have the router combined with the power adaptor ("wall wart"), so the signal originates inside.
12-48V DC input is nice flexibility & so so easy for devices to do given the SMPS architectures they run off. 25-40W is both a big improvement but also a serious limitation for anyone lugging batteries about. https://www.starlink.com/specifications?spec=5
