I've just got one of these devices, having been using Starlink at home for a year or so. The mini dish fits easily into my carry on bag and I've tested it with an Anker battery pack. According to reviews, it works well through sunroofs and glass (I'm not planning on holding it next to an aircraft window) but I wondered about the usefulness of taking it on my trips. All hotels now have reasonable wifi and I don't tend to be sitting outdoors very much. In car might be the most useful place for it, particulalrly where cellular signals are bad, but am I just trying to find a problem for this solution?
