In the Bay area, my power-outage planning has been less about heat (it never really gets cold enough to be dangerous), and more about making sure we can still run air filters in case a wildfire and a power outage happen at the same time. For that, I have a couple of 75Wh Li-Ion batteries with inverters. The air filters I have use 45W on a high setting (significantly less on low settings), so this isn’t enough to run them on high continuously, but is enough to re-clear the air each time a door is opened and periodically deal with particulates that have leaked in. Lead-acid batteries would provide a lot more Wh/$, but they’re also heavier and less compact.

Makes a lot of sense! And in the bay, a simultaneous wildfire and power outage seems quite plausible.
