When any of my UPS kick the bucket, I'll most likely buy one of these things, as they can work as a UPS, and the battery life is several times as many years, so definitely worth it.
Bluetti should think about a product line that is simply UPS with either LFP or sodium, without the solar power stuff.
Bluetti has officially introduced the Elite 300 portable power station in the global market. Advertised as the world's smallest 3 kWh portable power station, the Elite 300 offers 2,400 W of continuous output, AC + solar dual fast charging, up to 10 ms switchover speed, app-based controls, and a LiFePO4 battery with a 6,000+ cycle lifespan.
