So I just bought this battery pack for my Thinkware dash cams. The manual says to hardware it to a 20A fuse using the provided Smart Fuse. Does anyone know which fuse inside a 2018 BMW X3 is 20A (or more), the owners manual doesn’t say.
For a BMW you're likely going to need to get permanent power directly from the battery, if you take power from one of the cars circuits you may find that the cars computer will have an issue with it
