My mini draws about 40-50w at start then stabilizes at 25w-30w at steady state. I put mini in my backpack next to my laptop with a 86Wh power brick and go hiking.
Phone now has satellite that makes me reachable. In case of emergency I bust out the mini and the laptop and I join the bridge.
This is not in theory, I actually joined emergency calls a few times.
Probably don’t need mini2 at this time. It only removes the power brick for me.
I find it's funny, when some hikers try to save every ounce of weight, to even using the Haribo powerbank because it's slight lighter than average.
Then there this guy who hiking with a laptop, a big ass powerbank and a starlink lol.
