If you're willing to spend the money up front I have two jackery 300 battery Banks and one jackery 1000 battery bank that is a lot of money up front but one jackery 1000 battery bank if you're only going to buy one will run your incubator for 12+ hours depending on its wattage it will also run a Cozy Coop heat panel for 8 to 10 hours or any kind of like Coop radiant heater I keep one because I live where we get a lot of heavy snow so power outages in the winter do happen and I also use them in the house when I lose power too, I can plug a lamp in charge my phone Etc and you can buy the solar panel to go with the jackery too. I do have a solar panel mounted on the roof of the coop connected to one of the jackery 300s which runs their fan full-time in the summer but the other two I keep in the house and I keep charged it takes a long time for them to lose charge just sitting so I usually have to plug them in and charge them like twice a year just so they're always at 100% or 99% ready to use in an outage. I know that doesn't help for this round but just some advice for future incubations. I hope everything goes well!
