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.

Wife and I each have one of [THESE](https://www.anker.com/products/a1695-anker-power-bank-25000mah-165w?variant=44320657997974&ref=power-banks) from Anker (best battery backup I've ever used) and then [THIS](https://www.ecoflow.com/us/river-pro-portable-power-station) big boy from EcoFlow with a couple fold out solar panels. Done us great through multiple trips and power outages. Pretty much my perfect setup, not sure what I could improve if I wanted to beyond more solar for faster charging, maybe another big battery unit (they can daisy chain) but I haven't ran the one I've got dead yet so it's clearly not pressing. We also have [THIS](https://www.bougerv.com/products/crpro30-vip-30-quart-portable-fridge) electric cooler that can plug in or use a 9h battery for camping/travelling/power outages. VERY happy with it's first road trip from Seattle to Vegas and back, when we got home with covid we just plugged it in and our leftovers were still 31f a week later when we felt good enough to unpack.
