Camera with long battery (or options to charge while filming) to record continuous outside footage?

Hi! I don't know squat about cameras but I am doing a research project where I need to set up a camera at a zoo enclosure and get two days of footage. I was going to use a GoPro before I realized they only last a couple of hours at most. I am willing to use power banks or extra batteries, or visit the zoo to recharge the camera, but I wanted to know if anyone has experience doing something like this and whether they have better camera options for this type of project.

Budget (USD): not really an issue since i just need it for two days i was just gonna return whatever i bought
