I use a Roamsat case for my mini and absolutely love it. Built in power and it’s weatherproof. The case comes with options for either suction, magnet, or rubber nubs. The built in battery powers the Starlink for about 7 hours on a charge (plenty for my use cases) and can also be run through a charge cable that bypasses the battery. Had it on my truck hood at highway speeds exceeding 100mph and it was absolutely rock solid. Downside is the cost, but it’s an extremely well built and engineered product.
