Laptops are not an emergency item. when the power goes out I for one don't go immediately looking for my laptop. I look for my phone, and then immediately go looking for any flashlight, because I need to save as much power as possible until the power is back up.
Every year there's a hurricane, wherever it passes, a good amount of people will be out of power for maybe a week, If you cannot buy a battery in the corner store, you haven't bought a flashlight, you've bought a toy.
In my house, we hand candles and oil lamps instead of flashlights. To this day, I still have more candles than flashlights. A benefit of candles is most people are okay with them being part of the decor and visible where flashlights/torches tend to be in a drawer and maybe the batteries are still good when needed.
