We've been on a little road trip this weekend and the Mini has been really useful since we left with no plans and have had to basically boondock each night so far because our campsite destinations were all full or closed for the season.
Due to some unforeseen circumstances we ended up looking for someplace to overnight in the dark with no cell coverage so we tossed the dish in the dash of our Transit and it worked great while we were driving around. I did not align it or check for obstructions.
I've been plugging it in to our BioLite Basecamp 1500 charging station with the USB-C cable and after several hours one day, and several yesterday I left it on all night and my BioLite is only down to 70% charge. I also used our Jackery 1000 with the AC cable a few weeks ago and the power consumption was decent.
I've got some mounting hardware I have to try out for the roof but haven't messed with any of it yet, and these are just for while at camp and not for driving. I plan to make my own mount for the roof for driving at some point, but it works so well in the dash I might never get around to it.
