Heyo, I'm looking to buy either a crackpot or a multicooker like the ninja possible cooker (not a pressure cooker)

I normally use a crackpot but I forgot to bring one, living in a cabin for the next 3 months with only a microwave, so I need to get something to cook with.

I like the idea of a multicooker, since I don't have many cooking options - but realistically 90% of the time it would just be used as a slowcooker. (Also feels silly to buy a second crackpot when I have one in storage at home) Do they do a comparable job? Slow cooking is still my top priority over the other features
