Any Generators, Power Banks, Solar Panels, etc…?

Edit: So I’m gonna answer my own question. I’ll probably freak out and would have zero generators to deal with it. Heater is Gas, but I don’t know if gas would work during power outage. Cooking, well there’s a butane burner stove. I have 3 10000mah batteries, but they have 60% efficiency due to power loss during transfer, so its effectively 6000mah, enough to roughly charge my 5000mah battery once, 3 batteries is 3-4 charges. Then I’d be bored with zero entertainment, along with all the food melting and going bad, very not fun 🙃
