Ya, I don't think you really need that much as a UPS but if you ran the AC180 in UPS mode, it would turn the fan on every 15-20 minutes as the circuity in the battery is still powered by the battery, even though the power is fed to your gear from the wall power. That results in it slowly going to 99% and then charging, which is noisy on the non-elite models in a quiet room. These LFP models are good for like 3000 cycles though, so using it as UPS it'll still last a decade or longer with 80% capacity left over.

There's the Elite 30 which can be a nice little battery backup / be portable and isn't too much more expensive then the comprable SLA types that don't last long.

Have you ever tried running a small coffee maker off of one of those? I've been trying to decide what power supply I'm replacing my battery system in my pop-up trailer with and I didn't want to go with anything that was too large or takes up too much space. But this looks like for price it's near perfect for my use case. The only thing I'm ever curious about is will it run my coffee maker in the morning. And what kind of charging are you using for it? Do you run solar off of it?

Ya they don't have that ability yet. If it was on something you'd want to shut down cleanly you'd want to be there to do it yourself or be able to remotely do it. The advantage of these new LFP ones though is it can last for hours instead of minutes, so there isnt a huge rush, and if your outages are short, it might not be an issue.

Edit: i had my internet, a couple security cameras and a small low power computer running some things last the whole ~1h45m outage last time I was away and power went out.
