Video out

I am going camping and want to have a way to watch movies and not on the "small" screen. I can't find info about MHL for the Note 5. All I saw was screen mirroring and my tv in the camper doesn't have that. I do have a Sony Bluetooth stereo but I don't think video will work over it. So how do I get video out?
I am using Amazon Prime video on Android with the download feature so I can take movies with me. It's supposed to rain tonight and would prefer to watch tv not the rain.
