There are some that can be recharged with solar panels and/or a wind turbine. However, that just adds to the cost. I've heard, haven't confirmed it yet, that if you buy from one of our local battery stores, they'll let you recharge it during a storm at their store. Of course that is assuming their store is able to reopen.
I just really need to keep my phone and laptop charged for medical communication. The mini fridge would be a plus along with a small fan. I have no plan to do big appliances at all. I have a grill to cook food if I need it. I had to evacuate to Louisiana during Irma. One of the sneaky things our county does is, they drive around listening for generators. If someone on your street has one, your street gets put at the bottom of the list for power repair.
I've watched this video a few times. I think it might work for my needs.
