And so is the Bluetti... if you had read the page through (before you dismissed it ) you would have seen the PRO model which is good for whole house backup (which is the title of this thread).... and it is sold through Lazada... here is a vlogger who bought one and reviewed it
Both are very good, wouldn't mind any of them. ecoflow pro can connect extra batteries if need be. But the bluetti has a larger battery.
