One of the ultimate must haves for preppers is the solar powered battery. It’s also very handy for off grid solutions. The best part about it: when the power goes down, the sun will still charge your battery and the sun will ofc not go out (unless the sun doesn’t shine ;)).
You have them in so many different price ranges and different power ranges, so you need to take a close look at where you will use yours for and what your budget is. If you need it to just power you phone charger or example, you will be able to buy a smaller less expensive model, but if you plan to power your refrigerator or freezer, you will need a bigger one.
Have you already bought a soloar powered battery for yourself and your emergency supply?
