Fair enough Spiritburner, of course for me it would be a deal breaker as I would not be able to make a cuppa with my 12v 350w kettle !
The reason I guess why the Ecoflow only offers 10amp at 12v is probably because the unit is using 24v or 48v architecture, so they will have used a 12v 10amp regulated buck converter for the 12v outlet, guess they cheaped out there as a 30amp buck converter would have added cost, but would have been a nice feature.
As the saying goes, "What will do more, will do less".
Maybe not quite as niche as you might think Spiritburner I notice that the Aferiy P280 has 12v 25amp outlet, which would probably run my 12v 350w kettle, as I guess it would cope with a 31amp load for 5 minutes.
The Afriy P280 seems a decent bit of kit for the money considering it has a 2,800w inverter, and around 160ah (2048wh) of LFP battery capacity, and like the Ecoflow supports additional batteries.
I would probably struggle to build my own version with that spec for the £700 price tag.
It could become mainstream tomorrow & it wouldn't change our MO. Once our vans leisure system is upgraded to 460ah, fast charging & increased solar next month the Ecoflow will mostly be redundant except when I shift it to my little slumcamper for charging devices & low amp minimal 12v use. Other systems will be powered by meths & paraffin.
with that set up Spiritburner, you will be able to go off grid indefinitely, these are interesting times indeed, Starlink Mini is built for mobile use, it's all good news for those wanting to wander.
