When you solve this specific problem it really takes a headache away. I’ve got complete confidence now that even turning my fridge on overnight whilst on the driveway before I need it for a trip or to work out of it as a mobile office the next day, when I come to put things in it the next day it is cold and not orange winking at me with the “yeah, I switched myself off 14 hours ago!” attitude.
I suspect for you that battery will still be a factor - but a beefier cable in the meantime direct to the battery gives you the best chance of finding out by ruling out other factors.
If and when it comes to it I recommend the fogstar I went with as a budget option. It hasn’t put a foot wrong in a year. Another fire and forget solution. I understand there’s and even cheaper ECO version now that’s only just a bit more expensive than a large standard leisure battery.
Good luck. If you solve it, be sure to post!
