    My Starlink dish uses around 60watts average, up to 80 sometimes, but I think it can draw more. So if you want to run it for 24 hours, you'll need at least 24*60=1440Wh. I didn't have it during Helene when I needed it the most, but now I have a Anker C1000 that I really like. It's small and only has 1056Wh of energy, but I don't need it to run my Starlink dish 24/7, just a few hours at a time. And I can recharge the C1000 in an hour with my gas generator. During Helene, I had to run my gas generator whenever I wanted to charge phones or laptops or use Starlink which was annoying. It's nicer to be able to run everything from a battery bank and then recharge that with the generator.

    I watched countless YouTube videos and read countless reviews about this market over the last two weeks and Ecoflow comes out on top basically every time. The only thing I’m not getting through Ecoflow is the panels and that’s because you can get a lot more for your money if you don’t go for foldable ones. I wish I would have bought on the last Amazon Prime sale, but I’m going to get the Delta Pro Ultra on Black Friday. I’m just some dude though, so what do I know.

    I might just need one F3800 with two expansion batteries, which provides 12kwh power to run my essential appliances. I just checked their website and found out they're around $6K. That looks reasonable. Bluetti ac500 and ecoflow delta pro might not in my lists cuz they cannot support 6000W, while delta pro ultra is too expensive. I need one can go up to 6000W and support high-voltage appliances like AC, fridge and my LG dryer.
