One other thing to watch out for that
@drewby already alluded to is the Amperage draw. Here in Tennessee, as you may have heard, had a bad ice storm last week like many other areas. Fortunately, WE did not lose power, but we have some friends that are still out of power and the electric company is saying it could be another 7-10 days before they get it back. It really made me start thinking about options in case we do lose power in the future.
Fortunately, we have a gas water heater that requires NO electricity, and we also have a gas furnace. I watched
this YouTube video a few years ago where the guy shows you how to rewire your furnace to run on a traditional heavy-gauge extension cord plugged into a 110V outlet. Then, when the power goes out, theoretically, you can plug it into a battery power station like a Jackery, EcoFlow, Anker, etc.. Granted, it wouldn't run it 24 hours a day for a week (unless you had the multi-thousand-dollar power station), but if it ran it for 10 minutes an hour during the coldest temps, it MAY keep your house warm enough to keep your pipes from freezing.
Anyway, I was going to do it, but never got around to it. Fortunately, I didn't need to worry about it this time, but I did follow through with the video, and the new wiring works just fine. However, when I plugged it into my Anker Solix C800, it would run for a few minutes and then the Anker would shut off completely. This was confusing me since the Anker has a 1200Watt continuous and 1600W peak output. So, I plugged the furnace into my handy-dandy device that measures wattage and amps passing through, and sure enough, the wattage never got over 1,000. However, when it was at peak draw, it was hovering around 9.85 amps. The Anker's output is 1200W at 10 Amps. My guess is that it was occasionally spiking over the 10 Amps, and the Anker was shutting down as a protective measure.
Anyway, I'm not 100% sure what the amps out are on the inverter but that is something to consider in addition to the total wattage. I'm considering buying a larger Anker that has a 20Amp output for emergency purposes. I really like the Anker's because they have a "turbo charge" feature where I could conceivably have the 2KWH station recharged completely from my truck (or Startbucks/McDonalds) in less 1.5 hours in an emergency. Some of the others have the quick charge as well but since I already have an Anker and the app to control it, I may keep my next one "in the family" so to speak.
