This is my kit I use for doing some Hyperlapse Astrophotography with my S23Ultra
Pretty simple set up, a tripod, phone tripod adaptor, 10W Samsung Battery Pack, C type cable, S23Ultra.
The tripod wasn't an expensive brand and the phone tripod adaptor was $10 from Ali Express.
I connect the battery pack and then I know I have all the power I need for up to 8hrs of filming.
You can see the hyperlapse settings I use in this post.
And the result
