12 Volt Portable Oven

Have any of you used one of these? I have a couple trips planned that are going to be more than 5 days long. I will have limited solar power. 200 watt solar generator. It will power our alpicool fridge. Does great! Plenty of power left in the morning.
I cant eat a lot of foods. Preservatives, flavor enhancers, coloring, grease. it kills me. I am also diabetic. So I need to make quite a few meals.
Good? Bad? Did it warm? Did it cook?

What was your experience? Your thoughts?

I’ve used a “Hot Logic Mini”, which is similar. It heated up nicely and works well. For example, I was able to heat up a frozen Lean Cuisine within a couple of hours and it was the perfect temp, nice and hot.
