Since I live in Florida, AC is necessary and while I had a couple of solar panels and gold cart batteries plus a 1400W inverter to make coffe in the morning, I also carried a portable generator & fount that 2200W could run the AC and the Westinghouse I used was also designed for electronics.
For more than you ever wanted to know about portable generators see
here (and links). From 2017 but still relevant.
ps sold my 2720 since have an empty nest but would not mind a 2417 or similar.
