The Bluetti AC180 will draw at most 1440W when recharging. The Honda eu2200i will charge it just fine, the Bluetti will get up to 80% charge in 45 minutes. This is actually my strategy for dealing with power outages going forward. I have an Anker Solix C1000 that I'll use to keep lights on, Starlink on, phones charged, and some other basic stuff. When the battery starts to run low, I'll charge it with my generator (Predator 2000 inverter generator). I just had to deal with 11 days without power and having to run the generator to get internet and charge our phones was a pain in the ass.

Sure, so, at least as of now, and I'm still playing with ecoflow, bluettis randomly shutoff even if they have a load. Usually, it's an issue of ECOmode being turned on, but we've had it happen when it's off enough times to confound me. We haven't had ecoflow do this yet. Bluetti's have to be carried. Nice handles, heavy and bulky to lunk around. The ecoflows we got have a wicked cool wheel setup with a handle we didn't know about until I bumped it. Bluetti accessories stay in a bag, the ecoflows we are using have compartments. Bluetti has nifty wireless charging spots on top of their cases, I didn't see this on the exoflows but I really don't care about that as a gimmick. (That's a personal thing) Bluetti has API access, which I have yet to work with to integrate with our systems, Ecoflow has an app, but I'm hopeful that I can figure out integration. For Californians - ecoflow is on the list of state approved systems - much easier for permitting since we can point at it on the state website. Also, Bluetti's touch screens and menus are interesting, but highly inconvenient and excessive. The ecoflows we got keep it simple and clear. It's entirely possible that our perspective changes over time using the ecoflow system, but, at least right now, we're pretty happy with what we're seeing after trying out Bluetti's products. But, for all the companies doing this stuff - great job! They're making portable, rechargeable, renewable energy systems accessible to the lay person in a plug-and-play way. I wouldnt want to knock anyone for accomplishing such a feet!

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.
