I bought a 12 volt cigarette socket lead (plugs into the Starlink dish) off the eeeeBy mob .
So it will power your Starlink Mini if you get two 12 volt batteries hooked up to make 24 volts .
The Starlink Mini will operate from 12V but do not use the supplied 15m cable, it is too light and the voltage drop too high. Jaycar do an adaptor with heaver cable.
